How to block or unblock a phone number on Android

If you don’t want to get calls from a certain phone number, you can block it. When the number tries to call you, your phone declines the call automatically.
Note: Some of these steps work only on Android 6.0 and up. Learn how to check your Android version.

2. Tap Call history .
3. Tap a call from the number you want to block.

Note: If your phone doesn't have visual voicemail, you could still get voicemails from blocked callers. Learn how to see voicemails listed in your Phone app.

Unblock a number

2. Tap More .
