Unblocking a phone number allows you to receive calls and messages again from a contact previously added to the blocklist. This can be done at any time through the app tab or on the specific phone number page.

Via the Blocklist Tab

1. Tap the Blocklist tab in NumBuster
2. In the list, tap the phone number that needs to be unblocked
3. In the pop-up window, tap Delete—the phone number will be removed from the blocklist

On the Phone Number Page

1. In NumBuster, find and go to section for the phone number that is blocked
2. Tap the Unblock button to remove the phone number from the block list

Once unblocked, you will be able to receive calls and messages from this phone number again.
