How to Turn Off Location Services on Android? [2021]

Location services on Android can be turned on and off without you knowing properly.

There’s a reason why apps ask for permission to use your location so regularly, even if they work fine without it. Many organizations, such as Google, rely on your location data to give accurate weather forecasts or the most up-to-date traffic events.

In some circumstances, apps may just require your location data for market research purposes. If you’re not sure what information you’re transmitting or just want to remain anonymous, here’s how to turn off location services on Android phone.

Note: While it’s simple to turn off location services entirely on your iOS or Android smartphone, you can also turn them off for certain apps. Because some apps rely on location services to work, you may want to make some exceptions.

Disable Location Services on Android

Android versions work on “stock” as well as custom interfaces depending upon the manufacturers. The procedure, though, should be comparable enough to follow.

We are going to use Samsung S20 with Android 10 running under OneUI of Samsung.

 To disable location services on Android, follow these steps:

Step 1: Open “Settings” from the app drawer or simply go to them via the top right corner of your notifications panel.

samsung settings

Step 2: Tap on the “Location”.

Step 3: Toggle it “Off”.

Disable Location Services on Android for Specific Apps

Specific apps run on android’s location services. If you frequently use Google Maps, or apps that may use location, you may not want to disable the location services on Android. If you don’t, then you can disable the location services for the specific app instead of the whole.

Follow these steps to do so:

Step 1: In the “Location” settings, go to “App permissions”.

app permissions

Step 2: Select the app you want to disable the location services for.

Step 3: Make sure you toggle “Deny”.

Disable Google Location Services

No matter what Android you are using, Google will have its location-specific apps running and turned on in the background.

If you are a privacy paranoid, follow along these steps to disable these Google Location Services:

Step 1: Go to the “Location” in the settings.

samsung settings location services on android

Step 2: Here you will find Emergency Location Service, Google Location Accuracy, Google Location History, Google Location Sharing, and Location in Search.

Step 3: If you find it “On”, you can disable it by tapping and toggling them Off.

One-time Access

android one time access

You can allow apps to ask for one-time access to location services on android to complete certain tasks. When the notification appears, select “Only this time” to allow the app to access your location for a single time before disabling it (iOS has a similar feature). This is a great way to get specific information without having to give an app broad access.

The Bottom Line

The privacy implications of location tracking data, which is at the center of our modern life, are rarely discussed. The information about a person’s whereabouts is extremely sensitive. It’s not so much about personal privacy as it is about a web of interconnections. If you’re a victim of a data breach, you’re not the only one who suffers; anyone with whom you have a relationship also suffers.

What is the answer? Keep a close eye on the apps you download and the rights you provide them. Be aware of the implications of allowing location services. Examine your social media privacy settings to improve your privacy.

How to Turn Off iPhone Location Services? [2021]

iPhone location services might look quite normal to you but they are a very serious privacy threat. This post will guide you on how to take control of your iPhone location services and monitor what apps are harvesting data through it.

Have you ever wondered why apps ask for your location services permission? They mine through your private data to make use of it. And how would you know what apps on your iPhone are tracking your location? Even if you are not using your phone, still these apps can record your data possibly after every 2 seconds.

Even though Apple has a very secure server and they claim not to sell your data. But many other apps do use this data.

How to check your iPhone location history?

iPhone’s default setting automatically records your location. You can log in to view your iPhone location history just to get a head start of how important this really is. As per Apple, “your iPhone and iCloud connected devices will keep track of places you have recently been, as well as how often and when you visited them, in order to learn places that are significant to you. This data is end-to-end encrypted and cannot be read by Apple.”

Here’s how you can view the iPhone location data

Go to Settings> Privacy> Location Services> System Services> Significant Locations> History. You can also turn this off.

How to stop iPhone Location Sharing?

It is sort of convenient to share your iPhone’s location with your contact but if you are a privacy paranoid, turn this off with these steps:

  • Go to the “Find My iPhone” app.
  • Tap “People”.
  • Tap and select the contact’s name.
  • Select “Stop Sharing My Location”.
  • Tap and confirm “Stop Sharing Location”.

As a privacy freak, you would love to view these iPhone privacy tips.

iPhone Location Settings

iphone location for apps

App permissions are very significant. You really need to be careful which app are you permitting to track your iPhone or look into your iPhone location services. Apps can use your location and even display at times without your knowing. They may use this data for machine learning and/or targeted ads but hackers are loving these location data services. Stay safe.

How to turn off iPhone location services for selected apps?

Go to Settings> Privacy> Location Services. For each app, you will be asked to choose between Never, Ask Next Time, or While Using the App. You can select as per your preference but we advise you to go for Never if you don’t want apps to track you at all.

When to turn off iPhone location services?

Ride-sharing, delivery, or fitness apps need your location to work appropriately, yet numerous apps run behind the scenes discreetly assembling information when they’re not effectively being utilized. Restricting or turning off iPhone location services totally could have results. Understanding what organizations don’t esteem your privacy is vital to staying away from smartphone apps taking your information.

How to turn off the iPhone location services completely?

turn off iphone location services

Go to Settings> Privacy> Location Services. Simple toggle/tap the button above and the location services will turn off completely.

You can also reset your iPhone location settings to factory default. This means you will need to grant the apps permission of your iPhone location services again. For this, simply go to Settings> General> Reset> Reset Location & Privacy.


We hardly pay attention to the privacy implications of location tracking data, which is at the heart of our modern lives. Data about a person’s location is highly sensitive. It’s not really about personal privacy, but rather about a network of connections. If you’re vulnerable to a privacy breach, it’s not just you who suffers; anyone with whom you have a relationship suffers as well.

What is the solution? Pay special attention to the applications you install and the permissions you grant them. Be mindful of the consequences of enabling location services. To improve privacy, take a look at your social media privacy settings.

The art of recognizing and getting rid of phishing scams

One of the most aggravating risks we face is phishing. Even though most of us understand what a phishing scam is and how it works, we are always caught off guard. This cyber attack  is a form of social engineering that is typically used to steal private information from users, such as their sensitive credit card details and login credentials.

Frankly speaking, we’re all aware how to get rid of phishing scams, although we fail to realize how sophisticated targeting is growing and we still (unconsciously) end up entertaining these cyber attacks. Thus, we need to comprehend the anatomy of phishing attacks and best practices to get rid of phishing scams. 

DISCLAIMER: Since hackers are resourceful, artsy, and constantly devise new ways to penetrate cybersecurity safeguards, no single strategy is likely to provide absolute safety. However, organizations can do a lot to raise awareness about phishing scams and how it operates by implementing policies, practices, and training.

The phishing attack’s anatomy

As the planet earth fights the deadliest Coronavirus offline, cybercriminals are trying to profit from the case online. Due to the large number of people trapped indoors and thus digital, phishing campaigns have increased by 600% in the last year (and yes, by last year I mean 2020!).

ICYMI, scammers often use social engineering as part of their phishing schemes to trick their victims into trusting them for fraudulent purposes, often by pretending to be a legitimate individual or company. Criminals may use phishing attacks to distribute malware and other malicious material. 

How does phishing scams work?

The following is the most common scenario:

  • When you open your email, you are greeted by a message from your bank. When you click the link in the email, you will be taken to a page that resembles your bank in appearance.
  • The catch is that this website is set up to steal your personal information. The warning will inform you that there is an issue with your account and that you must verify your username and password.
  • You will normally be directed to the actual institution to enter your credentials a second time after entering your credentials on the page that appears. Since you are directed to a reputable organisation, you are not immediately aware that your information has been compromised.

How does a Phishing Email appear?

One of the reasons phishing emails are so dangerous — and so often popular — is that they are designed to appear legitimate. The following characteristics are commonly found in phishing emails and can raise red flags:

  • Ties or attachments
  • Spelling error
  • Grammatical errors
  • Graphics that aren’t professional
  • Unnecessary stress over instantly checking your email address or other personal details
  • Instead of your name, generic greetings such as “Dear Customer” are used.
  • Since hackers often hurry to set up phishing sites, some of them will appear to be very different from the previous business. These characteristics can be used to identify a phishing scam that strikes your spam section.

Phase 01 – The evolution of phishing scams

What began as an attempt to steal users’ credentials through email and instant messages has since evolved into new ways, such as SMiShing, or adapted its content to hook the victim with a surprising subject line.

Phase 02Why has this cyberattack still haunting since its very inception?

FYI, phishing scams doesn’t necessitate extensive networking or even basic knowledge of programming. It actually relies on human error, capitalizing on their emotions, and a lack of security knowledge at all, exploiting the psychology in the same way as technical tools do. 

Phase 03 – Nature plays harder

Our inherent psychology (i.e. human nature) fails to recognize cyberattack like a typical (or more advanced) phishing scam. This is one of the main reasons why phishing has become so popular among hackers. Sadly, perpetrators also use negative or upsetting news to pique the interest of their target, causing them to click on suspicious links or willingly hand over personal information.

Phase 04 – Phishing scams bait-and-switch

This pandemic led recession has forged numerous closures amongst businesses environment or the mandatory restructuring leading to uncertainty in the job security area. In reality, phishing emails with the subject line “HR Redundancy List” have recently been discovered in some companies. Fraudsters use intimidation tactics to entice recipients to click on a link contained within emails or download harmful material via these malicious attempts.

The very nature of phishing scam not only encompasses these tricks but also has bookmarked the unimagined work-from-home scenario. The increase in the rate of global unemployment and desperation towards work-from-home practices has made these cyber attack attempts so powerful that it has been hard to get rid of phishing scams. This has challenged the mere scope of cyber security. 

Users should not, however, users should remain tacit when job searching, otherwise it would deter them from detecting phishing indications. Some phishing texts and emails, according to The Motley Fool, claim to provide work-from-home job opportunities, loans, or other types of financial relief. 

Phase 05: Recognition: The very nature of human psychology

Most Americans claimed to receive hoax messages from “FCC Financial Care Center” promising $30k in relief for those who have recently been furloughed, according to the Federal Communications Commission (FCC). Since this may seem to be an achilles heel, it is actually a sneaky downfall designed to dupe victims into handing over their credentials.

Pro-tip: Disregard emails that fall in such categories

  • Any email requesting personal financial details in a hurry should be avoided.
  • To get people to respond quickly, phishers usually include disturbing or exciting (but false) statements in their emails.
  • They usually ask for user IDs, passwords, credit card numbers, SSN, and other personal details.
  • Genuine messages from your bank or e-commerce company are usually personalized, whereas phishing emails aren’t. Wait, modern sophisticated are “too personalized” (check act fast).

Phase 06: Types of phishing scams

  • Phishing scams appear in your inbox, typically requesting that you click on a connection, send money, respond with personal information, or open an attachment. The sender’s email could be tailored to look like a legitimate one, and it could contain information that feels unique to you.
  • Voice phishing (vishing) Scammers use voice phishing (vishing) scams to trick you by impersonating a legitimate individual or organisation. They can disguise their phone number and redirect you from an automated message. Vishers will try to hold you on the phone as long as possible, pleading for you to take action. This could lead to sim hacking.
  • Domain Spoofing an email phisher can use domain spoofing to imitate legitimate email addresses. These scams alter a legitimate company’s domain (for example, You could become a victim of the scam if you interact with an address like “”
  • Smishing – Phishing Scams via SMS (smishing) This scheme, like vishing, would mimic a legitimate organisation by using urgency in a short text message to deceive you. You’ll typically find a connection or a phone number in the message that you can use. This also applies to mobile messaging systems.
  • Clone phishing is when a valid attachment or connection is replaced with a malicious one in a previously sent post. This is most often seen in email, but it can also be seen in other places, such as false social media profiles and texts.
  • Criminals use posts or direct messages on social media to trick you into falling for a scam. Some are overt, such as freebies or dubious “official” organisation pages with a pressing order. Others can impersonate your friends or develop a long – term relationship with you before ‘attacking’ to complete the transaction.

Phase 07: In other cases, legal websites can be hacked or imitated using the following methods:

  • With the classic “padlock next to the URL bar” indicator or infamously known as the HTTPS phishing scam gives a fraudulent website the appearance of protection. Previously, this encryption sign was only available to sites that had been verified as secure, but now it is available to any site. So, while your link and the information you send may be hidden from outsiders, you’re still linked to a hacker.
  • When an unattended fraudulent page reloads into a spoof of a legitimate site login, this is known as tabnabbing. When you come back to it, you may mistake it for the real thing and unwittingly give it access to your account.
  • Typosquatting (URL hijacking) is a method of chasing people who type the wrong URL for a website. For instance, “MccDonald” instead of “McDonald” could lead to an unwanted nest.
  • Another branch of phishing scam is “watering hole phishing” targets famous websites that are regularly visited by a large number of people. An attack like this might try to take advantage of flaws in a website to launch a variety of other phishing scam. Malware distribution, link redirection, and other methods are often used in this form of cyber attack.
  • Pharming (DNS cache poisoning) reroutes traffic from secure websites to phishing sites using malware or an onsite vulnerability. If a domain is pharmed, manually typing a URL would always take visitors to the malicious site.

Personal and public email addresses:

Create a private email address. Only personal correspondence should be sent here. Since spammers create lists of potential email addresses by combining obvious names, words, and numbers, you should make it difficult for them to guess your address. Your private address should be more than just your first and last name, and you should safeguard it by doing the following:

  1. Never put your private email address on a website that is open to the public.
  2. If you must publish your private address online, try to mask it to prevent spammers picking up your address. Spammers can easily locate email addresses like ‘’ Instead of ‘,’ try ‘’.
  3. If spammers discover your private address, you can update it. Changing your email address can be annoying, but it will help you prevent spam and scammers.
  4. Make a public email address for yourself. When you need to register on online forums and chat rooms, as well as subscribe to mailing lists and other Internet services, use this address. 
  5. Make yourself a public email address. Using this address to sign up for online forums and chat rooms, as well as to link to mailing lists and other Internet services. Don’t be afraid to switch up your public email address on a regular basis.
  6. Make use of a variety of public addresses. You’ll have a better chance of figuring out which services are selling your address to spammers this way.

ACT FAST!! How to eventually get rid of phishing scams?

We’ve to act fast. 


  1. Go straight to the source, first and foremost: Be wary of text messages or the emails purporting to be from firms that make unusual requests or provide information that seems to be smugly moralistic. Instead of clicking on a connection contained within the email description or link, go directly on the website of the mentioned company or contact their customer service/ live chat, whatsoever.
  2. Be wary of emails that invite you to take unwanted action: Do not click on something in an email or text message that asks you to take a specific action or download apps. Instead, revert to step 1, visit the organization’s official website or social media. You will no longer be able to or urged to download malicious content from phishing links.
  3. Set up a security software or upgrade carrier plan automatically to protect your mobile device. A mandatory update policy in an organization can also pluck any incoming cyber security threat in advance and mitigate it to an acceptable level. These adjustments can provide you with essential security protection against unwanted hacking, such as sim swap
  4. Employees technical training: Although the first three are applicable for companies as well, another aspect would be to train employees to indicate different types of cyber attacks and get rid of phishing scams.
  5. Multi-factor authentication is a good way to keep your accounts secure. Some accounts provide an extra layer of protection by having two or more passwords to log in. It is important for organisations and individuals to realise this and to have the resources necessary to resist it if they fall prey to it by using a password manager to prevent password reuse. However, if you have a complex or high-threat model, a hardware MFA such as a yubikey is something we strongly suggest. Anything like the Twitter hack couldn’t have happened if this had been in place.
  6. Back up your data to keep it secure. Create a copy of your data and make sure it isn’t linked to your network (on your home). Your data files can be copied to a cloud storage or external hard drive. Back up your phone’s data as well.
  7. Without opening the email, delete it. When you open an attachment or click a connection in an email, most viruses are enabled. However, some email clients allow scripting, making it possible to get a virus simply by opening an email that appears to be suspicious. It’s better if you don’t open them all at once.
  8. Block the sender manually. You can build a block manually if your email client requires it. Make a note of the sender’s email domain and link it to a blocked sender list. If you share your email box with someone in your family, this is particularly wise and useful. Someone else might come across a legitimate-looking email that isn’t in your spam folder and decide to do something with it.

How to Block Unwanted Spam Texts on Android and iOS?

You’re probably getting spammy text message updates if you have a smartphone. Security codes from your account, meal coupons, political party messages—the list is endless. Here’s how to avoid receiving unsolicited automatic texts from a business. 

In contrast to newsletters, SMS messages do not have “unsub” links. They frequently leave no instructions for unsubscribing. And if there are no directions for stopping a text message, there is a virtually standardized way to do so.

Simply reply to the text with one of the following words to unsubscribe from automatic text messages sent to your mobile phone number:

  2. STOP
  3. QUIT
  5. END
  6. STOP ALL (note)

NOTE – Send this message instead to be removed from all lists sharing the short code number. 

Numerous automated SMS services exchange “short code” numbers from which they submit you messages. Sending out a message like “STOP” or “UNSUBSCRIBE” to the number would delete you from the list that texted you last.  These are pretty common commands, and most systems that are will notify you right away if you use them. 

How can I block spam texts?

Some people send spam text messages, just as they send spam emails, and they ain’t going to stop no matter how nicely you’ve asked them to stop. 

Here are some considerations:

  1. How to block text messages from a number on iOS and Android
  2. How to block text messages from multiple numbers on Android and iOS

How to block spam text messages from a number on iOS and Android

On occasion, you can receive spam messages on your phone. People can be irritating at times. Often all you need to do is block someone. 

Blocking numbers on an iPhone has one minor idiosyncrasy: the number you wish to block should be saved in your Contacts, because there is no way of blocking a particular number otherwise. Howtogeek recommends users to create a dummy spam section so individuals can add spam contacts there to smooth the blocking process (this involves blocking texts and calls). 

You have an option to block a contact, directly from the message


  • If you’ve the text from that unknown number, the only way to block a specific sender is to do so directly from the message.
  • Tap the ‘contact’ at the top of the message.
  • In this menu, tap the ‘info’ below person’s name, then scroll to the bottom of the page.
  • “Block this caller” should be chosen.


So, here’s the deal: there are a ton of Android phones available from a variety of manufacturers. And it appears that nearly every single one of them has its own Text message app, making it difficult to tell you how to do it on your specific phone.

For the sake of clarity, I am going to show the blocking process on Infinix Hot 10.

  • Blocking SMS from a particular individual is as simple as blocking them from a sent post. To do so, go to the Messages app and open the chat thread from them.
  • Select “Details” from the three dots in the upper right corner.
  • “Block ” should be selected. A popup window will appear, asking you to confirm that you want to block the number, and will inform you that you will no longer receive calls or texts from this user. To confirm, tap “Block

Manually block the user’s number


  • To get started, go to the Settings menu and scroll down until you the relevant tab i.e. “Messages.” The menu can be accessed by tapping it.
  • Under the SMS/MMS subsection, about three-quarters of the way down this menu is an entry named “Blocked.” That should be tapped.
  • This is where all blocked numbers will appear. Tap “Add New” to create a new one in the list.
  • This will bring up your phone contacts; simply check for the contact associated with the phone number you want to block. Upon finding the digits that have to be blocked, click on the relevant action to block to get rid of those incessant messages. 


  • You can also manually type in the person’s phone number to block them if you don’t have an open message with them. Click the three dots in the upper right corner of the main Messages interface, then pick “Blocked Contacts.”
  • Mostly it would be a spam and blocked section and not every device prompts such action to add a new contact to be blocked. 

How to unblock a number on iOS and Android?

On iOS:

  • If you change your mind, you can unblock users by returning to the Settings menu and scrolling down to “Messages.”
  • Go to the “Blocked” menu and choose it.
  • In the upper right corner, tap “Edit.”
  • Click on the red icon. This is available to the left of the person’s name, and then tap “Unblock” on the right side to confirm.


  • Simple click on ‘x’ right next to blocked numbers on your messaging apps. This interface varies device-to-device. 

Please note that there will be another part to this blog where we’ll discuss how to apply spam filter to block telemarketing and other Mr. Random guy numbers on Android and iOS! Stay tuned, readers

Best Practices to handle roaming on an Android Device

The Android device is highly configurable, allowing you to manage simple phone features such as the usage of data and international roaming settings while you’re not on your own carrier’s network. This guide is intended to answer the following questions:

  1. The prerequisites of taking an android device overseas.
  2. How to set an android device to turn off data when roaming?
  3. BONUS

Renting or purchasing an Android phone in the country where you intend to stay is the most convenient way to use an android device when travelling. International roaming fees are often so high that it is often recommended to simply buy a temporary mobile phone wherever you travel, particularly if you intend to stay for an extended period of time. 

If you choose to use your own phone rather than purchasing a local mobile device, everything must go fluently — as long as you have access to a compatible cellular service in your area of residence. Not every Android phone is compatible with the same cellular network, and not every foreign country is compatible with the same mobile network. Before the mobile attempts to operate in response to the surroundings, it is important to ascertain the roaming charges you could expect from a foreign carrier.

Anyways, enough with the jibber-jabber, let’s get started chronologically. 

The prerequisites of taking an android device overseas 

Turning your phone on is one of the prerequisites to deciding that an android device can be used in a foreign country as a potential asset.  Another key determinant would be the emergence of a country specific cellular service where the previous carrier name once appeared.  So, if your phone previously mentioned Verizon Wireless, it could now say Telstra if you’re abroad, for instance.

  • When you’re travelling, make sure to ask about texting and cellular data (Internet) prices.
  • If you’re unsure, call your mobile provider for advice and details unique to the country you’re visiting. For example, efani offers international roaming via eSim.

How to set an android device to turn off roaming? 

Roaming may seem to be convenient, but there’s a catch: it almost always comes with a surcharge for using another cellular service — an unwelcome charge at your disposal.

Take a deep breath, relax!  When you’re roaming, disable all data usage in your Android’s key settings. A roaming “R” icon appears in the status area at the top of the screen to notify you once you’re roaming. 

  • As an initial step, press the “Home” button.
  • Select “Menu” from the drop-down menu.
  • “Settings,” “Wireless & networks,” and “Mobile networks” are the relevant options you need to tap.
  • Make sure the “Data roaming” feature is unchecked. Tap to remove the check.
  • To exit the “Mobile networks” settings, press the “Home” or “Back” button.

ICYMI – when your phone roams, it can always use the Wi-Fi connection to access the Internet. You don’t have to pay extra to set up a Wi-Fi connection, unless you have to pay to access a wireless connection.


Multimedia, or MMS, text messages are another network service you may want to disable while roaming. Follow these measures to prevent surcharges from another cellular network when downloading an MMS message:

  • Open the text messaging app on your mobile.
  • Tap the Back or app icons in the upper-left corner of the phone unless  the main screen of the app appears.
  • Tap on the Menu icon.
  • Select Messaging Settings from the drop-down menu.
  • The Auto-Retrieve or Roaming Auto-Retrieve commands can be used to remove the check mark. By the way, you’re good to go — practically — if the item isn’t selected.

How to set up visual voicemail [2021]?

Direct-access voicemail with a visual interface is known as visual voicemail. Rather than the sequential listening required by conventional voicemail, such an interface provides a list of messages for playback, which may include a message transcription with it. 

The masterpiece reinvention by Steve Jobs and YouMail

Apple’s iPhone was the first mobile phone to promote this feature back in 2007. YouMail was the very first third-party, multi-platform cell phone based visual voicemail service in 2007. The voicemail cloud storage was implied rather than the mobile carrier’s network and making it accessible from any email or web browser.

What is visual voicemail? 

Visual Voicemail allows you to view and listen to your voicemail messages (that you have received) in any order on your devices. You can navigate throughout your texts, choose those you would like to listen to, and delete those directly from the screen of your computer.

In a Nutshell: 

Visual voicemail gives us the ability to do the following:

  • Messages can be sent and listened to in any sequence.
  • Visually scroll through the texts.
  • By touching the screen, you can save, archive, or delete messages.
  • Obtain message transcriptions 
  • Send voice messages as an email attachment or as a text message.

Android voicemail 

The operating system of the Android comes with a native VVM feature that allows you to display voicemail messages as text. By moving into the device dialer, you have to click or swipe over to voicemails, you can see your voicemails.

Once you open each documented voicemail, you would be able to see a Play button (to listen to the message) as well as the message’s transcribed text. If you’ve an older version of Android, there may be a possibility that your service provider doesn’t offer this feature, so you are open to downloading a third-party application. 

Voicemail on the iPhone

Open the dialer app and press the voicemail icon in the bottom right-hand corner to access your iPhone’s built-in visual voicemail. Either you’ll be required to set up your visual voicemail inbox or you’ll be linked to an automatic voicemail system that only accepts audio messages. If the latter happens, and your carrier does not have visual voicemail, your safest choice is to download a third-party app.

Android – Google Voice

For calling, messaging, and voicemail, Google Voice provides you with a phone number. You’ll need a G Suite account, and text messaging isn’t available in every area. The voicemail system’s most important feature is that it transcribes reasonably well. You can also get the transcripts sent to you by email. For people who make a lot of intern calls, Google Voice is especially useful for those who make international calls more frequently.

How to set up visual voicemail?

It all begins with a voice message to text conversion. Getting a stenographer on standby to translate each call on your answering machine into text is akin to converting voicemail to text. The voicemail invention to text technology is comparable to the alphabetic invention. The ability to convert voicemail to text makes language more tangible. Text messages are, in a sense, tangible.

1. How do I activate Visual Voicemail Setup on an iPhone?

If your carrier supports Visual Voicemail, follow these measures to set it up:

  • To access Voicemail, open the Phone app and select the Voicemail tab.
  • Set Up Now should be selected.
  • After that, tap Done to create a voicemail address.
  • To double-check your password, type it in again, then tap Done.
  • Choose between Custom and Default. You can record a new greeting if you choose Custom.

2. How do I activate visual voicemail on Android?

We assumed the device to be Samsung in this case. There is less variation of the steps in android, however. 

  • From the home screen, swipe up.
  • Choose the Voicemail application from the drop-down menu.
  •  Enable the access to the Phone, SMS, and Contacts this is mandatory and definitely needed for Visual Voicemail Setup.
  • Accept the Visual Voicemail Terms and Conditions after reviewing them.
  • Once you get acquainted with the Visual Voicemail interface , select Continue.

Do I really need a visual voicemail?

I can’t imagine going back to normal voicemail after years of using visual voicemail on my computer for the following reasons:

  • To find a particular message, quickly scroll through your messages. Most conventional voicemail systems require you to listen to each message in your mailbox in order, beginning with the oldest. Visual voicemails allow you to quickly scan a message.
  • The ability to send yourself or someone else voice messages via email or text. This is useful if you want to send a particular message to someone without having to describe it to them. Sure, simple (non-visual) voicemail will forward messages, but it’s probably more complicated.
  • You don’t have to listen to the messages to get what you need from them if you use transcription. The message above is an excellent example: a quick glance revealed that it was about a pending meeting, and I just needed to read the first three lines.
  • There’s no need to dial a phone number to receive your calls. It might sound ridiculous, but I used to despise having to do this and would put it off until my inbox was completely full. That is no longer the case.

How visual voicemail secures you from your crazy ex – or – robocalls?

The robocall nuisance is growing parallel to this pandemic and other prevalent cyberthreats (such as sim swapping). There are many third party applications that resolve this problem, such as YouMail. 

Please note that we cannot speak on any third party behalf due to liability and insurance issues. However, best is to read or check the reviews and research online on the unique features offered by the product. You can always contact our BDMs or consultants at EFANI that would be more than happy to secure your online presence and your number against sim swapping threats

Comprehending Phone (Caller ID) Spoofing – A 2021 Guide

Over the past year, three out of four Americans claimed they had been targeted by phone scammers (caller ID spoofing). When a caller sends false information to change the caller ID, this is known as call spoofing or spamming.

A VoIP (Voice over Internet Protocol) service or an IP phone that uses VoIP to relay calls over the internet is used for the majority of spoofing. When setting up a VoIP account, users normally have the option of having their preferred number or name displayed on the caller ID.

What is spamming?

Spam encompasses but not limited to unsolicited messages and/or calls, robo calls, Caller ID spoofing, or any form of unwanted communication(s). Spam is intended to reach a large audience (i.e. targeted users) for phishing purposes or other purposes like spreading infectious malware, advertising etc.

Neighbor spoofing is a spoofing form where robo callers feature a number that looks similar to yours on your caller ID in order to get you to pick up the phone. This multiplies the chances of entertaining the spammer.

What is Caller ID Spoofing?

You may have an idea what spamming actually is, however, when it comes to caller ID spoofing, it is the practice to cause the network to indicate that the call has originated from another station than its original station.

This is accompanied by a caller ID that is shown on your screen, displaying a regular phone number but the motivation is deemed to be malicious or corrupt. Incessant ringing is one of the patterns that makes you question if I can trust caller ID?

A brief summary

  • When a caller intentionally falsified information transmitted to hide the number they’re calling from, this is known as caller ID spoofing.
  • In an effort to trick you into answering the call, the number displayed on your Caller ID might appear to be from a government entity, a company, or even someone on your contacts list.

The instances when Caller ID Spoofing is legal or illegal:

  • Spoofing is illegal if the caller’s intent is to defraud, damage, or trick you into providing information you wouldn’t otherwise provide over the phone.
  • Spoofing is not illegal if no harm is intended or caused. Some individuals, such as law enforcement officers or doctors’ offices, may have valid reasons to keep their information hidden.

Did you notice the term: neighbor spoofing?

I hear you! You must be wondering what neighbor spoofing is? Think deeply. The crux is that bad actors want your attention. They want to target you, they want you to answer their call. Will you entertain their motives?

Once you receive a call from an anonymous telephone that bears a striking resemblance to the numbers where you reside, this is known as neighbour spoofing. The caller ID would have the same area code as your phone number, and also the same prefix (the three numbers after the area code). The evil ones do it in the hopes that you’ll mistake it for a “neighbor.” You see, a trick? This is such a malicious one, beware!!

P.S This is what this blog is about, to educate our readers to take their privacy seriously.

Did you know?

Robocalls have evolved from a minor annoyance to an unavoidable plague. Though some of these calls are legal – for example, a candidate campaigning for office, a charity asking for a donation, or a school notifying parents and students about campus closures – many are not, and some are outright ponzi schemes.

Unnecessary robocalls are the most common source of customer complaints to the Federal Communications Commission and the Federal Trade Commission.

Enough with the terms, what is their motive?

Notice the pattern. The caller ID appears to be coming out of your own numbers, which is known as reflection spoofing. Once again, it’s a crook attempting to get you to pick up the call.

People are more likely to answer a call if they know the incoming number (via similar number, area code), so these tricks work. Even if you don’t recognize the figure, if it looks familiar, you’ll be less suspicious.

If you respond, the bad person will use a compelling argument to threaten you or manipulate you into sharing your sensitive passwords, credit card numbers, or other personal data. Trust me, even experts in the field fall for these scams, so there are certain tips to apply when you’re or have been a victim of incessant calling.

What are the consequences of answering these scammers?

These dangers are self-evident. The motives are to trick people so they could possess your personal information or even money-related information, or even both. The motives vary person-to-person. The bad guy could impersonate a banker, an authentic individual from a charity organization, or authorized individuals distributing phony prizes.

Senior citizens or older people fall for it as the common aspect of vishing (voice phishing) or smishing (SMS attacks) / phishing (email) attacks trigger them to entertain such calls because of lack of awareness of the surmounting spoofing/caller ID threat.

An illustration of spoofing

A common scam would entail a call from the IRS. The caller attempts to intimidate the recipient into believing that they owe money in back taxes or that they must immediately hand over confidential financial details.

Another popular scam is phony technical support, in which a caller claims to be from a well-known company, such as Microsoft, and claims that there is an issue with your device that requires remote access to resolve.

Getting calls from a colleague’s or partner’s mobile number when they are present but not calling you. Instead of the calling party’s phone number, Caller ID shows ‘911 Emergency.’

There’s more to come..

There are indeed “SMiShing” attacks, or phishing by text message or emails, subsequently, in which you may receive a message that appears to come from a trustworthy individual or reputed organization that encourages you to click on a provided link.

However, if you do, it can install a malware on your laptop, mobile device, sign you up for a premium service, or even steal your online account credentials. Horrible, isn’t it? It could also lead to a convenient sim swap (face-palm).

What makes Spoofing so popular?

The ease with which digital phone signals can be sent over the network has resulted in an increase in spam and robo calls in recent years. Since robo calls use a computerized auto dialer to send pre-recorded messages, advertisers and scam artists may position many more calls than a real person might, and they frequently use deception techniques including making the call appear to come from a trusted source.

What should you do if you get spam calls?

This is the summary of the pre-provided information.

  • Don’t divulge any private information. To obtain account numbers, SSNs, mother’s maiden names, passwords, and other identifying information, identity thieves often pose as representatives of banks, credit card companies, creditors, or government agencies.
  • Terminate the call immediately and dial the phone number specified on the account statement / business or government website (if the request is reasonable).
  • You can report unwanted calls here.
  • Most carriers offer Do Not Call Registry, it could be costly but it brings you peace when the risk of spoofing is reduced to an acceptable level. Be vigilant when someone asks you for your private number as this could lead to sim swap or open an unwarranted portal of hacks. If you are asked to fill an online form requiring a number, leave it blank on purpose. Do NOT list your number on any social media profile.
  • In case you receive a call from an unauthorized number, make sure to leave it unattended.
  • Make a habit of reading privacy policy on any service you sign up for. This will ensure if your contact information is not sold. One of the USPs of efani is that it never sells your information to third parties.
  • While entering for online competitions and sweepstakes you should be mindful to avoid provision of any sensitive information to other businesses. You could open up a risk of hacks as these companies sell your information to other companies. Be wary of it!
  • Keep up with the latest schemes so you recognize what to avoid, and set up mobile protection on your devices to protect yourself from malware and relatable threats.

The belligerent hacker

Scammers that use robocalling technology can be diligent, looking for new ways to get their calls through ever-evolving blocking solutions.

Often callers attempt to hide their identity while using a mobile number that they are not approved to use, like that of the number of such a government agency or a legitimate company with which you might have a business relationship, or a phone number that you are not familiar with.

As stated above, the number will resemble (because it will contain your area code creating an impression as if it is from your neighbor or your friend). In this way, they hope to get you to pick up the phone while avoiding technology that might otherwise block the caller’s actual mobile number.

NOTE: Do not even try to outwit the bad person by deliberately providing false details. Simply hang up. Do not contact the company back, or any other number they send you, or any numbers (or ties in texts) you are sent.

FYI or ICYMI: In the telecommunication sector, caller ID spoofing is popular. This issue affects landline, wireless, and IP-based telephone service providers alike. This isn’t a problem exclusive to one carrier.

The learning outcomes from this article

Is it okay to pick up the phone, nowadays? The quick answer is no. It’s most likely a robocaller.

They also say they’re calling from the Social Security Administration or the IRS. (They aren’t; either service that will ever harass you or claim compensation right away over the call.)

They can even call to inform you that your car’s warranty is about to expire and that your credit card interest rate may be reduced. Please be sure that you should NOT answer such calls.
