Understanding the Nature of Restricted Calls

Before you can effectively block these nuisances, it’s essential for you to understand what you’re dealing with when it comes to the nature of restricted calls. These are the calls that show up as ‘Unknown Number‘ on your phone, hiding the caller’s identity. This can be done using the *67 code or specific device settings.

While sometimes it’s just a harmless prank, other times it can be a part of cyber attacks like Smishing and Vishing. Don’t fret though, as there are ways to block these calls on both Android and iPhone devices. You can either block all unknown numbers at once or individually.

Service providers and third-party apps offer options to handle these calls, ensuring you stay safe.

Steps to Block Unknown Calls on Android

You’ll need to go into the settings on your Android device to effectively block unknown or restricted calls. Here’s how:

  • Open the ‘Phone’ app.
  • Tap on the three-dot icon at the top right corner.
  • Choose ‘Settings’.

Scroll down and select ‘Block numbers’.

Now, you’ve two options:

  • Toggle on ‘Block unknown callers’ to block all unidentified calls.
  • Or, manually type in the number you wish to block.

Remember, the steps may slightly vary based on the Android version and the phone’s manufacturer.

If you’re still receiving nuisance calls, consider downloading a third-party app like ‘Truecaller‘ or ‘Hiya’. These apps can help identify spam calls and provide additional blocking options.

Stay vigilant and don’t respond to suspicious calls.
