Two Easy Ways to Block Unwanted Calls on Your Android Phone

Posted by on November 18, 2013

Unwanted telemarketing calls can be both frustrating and annoying, particularly when they interrupt your sleep, dinner, or time with your family or friends.

If you’ve ever been annoyed by those telemarketers or other unwanted callers, then you can simply block their phone numbers so that they can not call you again. Here’s I will show you two different ways to block unwanted calls on your Android phone.

Method #1: Use the built-in call blocking feature on your android phone

Most android phones come with this feature, but the procedure may differ according to the device manufacture and the version of android that you are using. In this example, I’m using Samsung Galaxy S3 to do the trick.

Open the phone app, tap the menu button and navigate to Call settings -> Call rejection -> Auto reject list. You can check the ‘Unknown’ option to automatically reject all calls from ‘Unknown’ numbers or tap on ‘Create’ to add individual phone numbers that you want to block permanently from your phone.

Method #2: Use a Call blocking app

If your android phone does not has an built-in call blocking feature and you really want to block calls, then you can use call blocking apps that are available in Google Play store.

Mr. Number is one of the best call blocking apps that allow you block unwanted calls from any phone numbers. Not just calls but Mr. Number also allows you to block text messages. You also can reverse lookup numbers so that you can get information about the caller.
