Block specific numbers using Carrier services on Android

Sometimes, no matter how hard you try to shield away from spam, they manage to sneak into your call log or messages. This is when you can seek help from carrier services who can block a specific number on Android.

In the US, depending on your service provider, you can seek help from Verizon, AT&T, and T-Mobile. However, before using their services, make sure to analyze their terms and conditions.

Use third-party apps to block numbers on your Android device

Third-party call-blocking apps are an excellent substitute for the built-in call-block feature on your Android phone. FYI, Google Play Store houses many apps that can easily save you from bothering callers. Some of my favorite call-blocking Android apps are: 

Will blocked contacts get notified that they have been blocked? 

No, the blocked person won’t receive any notification that they have been blocked. Their calls will go to voicemail or appear as undelivered for texts.  

Do blocked calls go to voicemail on Android? 

Blocked calls might be redirected to voicemail, depending on your Android phone settings.  

Can I block a number from which I haven’t received a call or text? 

Yes, you can manually include a contact to your blocked list using the Phone app’s settings or third-party apps.

Where technology keeps you connected, it also blesses you with the power to choose your people. The built-in block facility in your Android phone is the perfect example of this.
