Block Calls: Android

Android offers two options to block unwanted calls. You can either use the blacklist feature to completely block calls or directly send calls to voicemail for preventing calls in specific situations.

Black List Feature

The Black list feature allows you to choose phone numbers that you don’t want to receive calls from and block them. When the black listed phone numbers tries to reach you, they will always get a busy tone. Here’s how you can block calls on Android.

Follow these steps to blacklist phone numbers:

  • From the home screen, tap ‘Menu’.
  • Select ‘Settings’.
  • Then select ‘Call Settings’ to reach ‘Black List’.
  • Tap on ‘Black List’ option to ‘Add Phone Number’. Type the phone number manually or insert from the contact list.
  • Click ‘ok’ and you are done.

You can also blacklist the phone number by selecting the contact and tapping the menu of the contact to select ‘Add to Black List’. Or else, when the number that you want to block calls you, follow the same method. You can easily remove the blocked numbers from the blacklist by going back to the list and unchecking the contact.

Voicemail on Android Phone

To block calls by sending calls directly to voicemail list, select the Menu – Edit Contact – then Incoming Calls and lastly select Send Calls Directly to Voicemail. The call will go directly go to the voice mailbox without notification. To disable this setting, follow the same instructions to reverse it.


You can also use third party apps to block calls on Android but you need to be selective when it comes to the Android OS. Here are some of the few options.
