Block a Phone Number or Contact on Your Phone
If you're receiving spam calls or someone won't leave you alone, you can block their phone number. That way, their calls and text messages will no longer appear on your phone. But don't worry, you can always unblock them if you change your mind.
Block Numbers from the Contacts App
The power is in your hands. Block unwanted numbers from contacting you.
Navigate to and open Contacts, and then touch the contact you wish to block. Touch More Options, and then touch Block contact.
Note: Even if you block a contact, they will still appear in your Contacts list.
Block Numbers from the Phone App
You can also manually add a number to your Block list.
Navigate to and open the Phone app. Touch More Options and then touch Settings. Then, touch Block numbers. Touch Add phone number and then use the on-screen keypad to enter the phone number you want to block. Next, touch the Add icon (the plus sign) to add the contact to your Block list.
Note: You can also navigate to the Recents section in the Phone app, and touch the phone number you want to block. Touch Details > More Options > Block number.

Or, navigate to and open the Phone app. Touch More Options and then touch Settings. Touch Block number and then touch the Remove icon to remove the corresponding phone number from your block list.
