Ultimate Ways To Block Unknown Numbers On Android

Incoming anonymous calls can be annoying. Many apps intended to block anonymous calls don’t work well. A third-party call-identification service can be expensive. Here are my best ways to block unknown numbers on Android.

Unwanted calls from unknowns are one of the drawbacks of carrying a phone in your pocket. You could, of course, ignore the call or say Adios, but that. By blocking unknown numbers on Android, you can prevent this. 

Today we shall go on a conquest to block unknown numbers on Android phones.

What Happens When I Block The Contact?

  • The blocked phone number is identified upon enabling the call blocking feature, and the smartphones won’t ring. 
  • You won’t get any notifications or alerts that a call is being made to you, regardless of whether you have blocked the phone number or followed the below-mentioned instructions to restrict all private and unauthorized calls
  • The numbers won’t send you SMS either.
  • If you check your voicemails, you won’t find them empty because the banned unknown caller can still leave a voice note.

On the contrary, private phone number blocking isn’t that ideal. A friend or member of your family who uses a private number will also be prohibited from calling because the setting applies a complete ban on all private numbers. This is because number blocking is a device feature, not a network function.

Due to the blocking feature’s inability to distinguish between family and strangers, it’s a good idea to inform your friends and family your phone won’t receive calls from their private numbers.
