Tap Block numbers and messages (or just “Block numbers” on some models).
Confirm Unblock . Note: Unblocking here also removes the number from the Phone app’s block list, as both apps share the system-level block list on Samsung devices. Method 3: Unblock via Contacts (Quickest for Saved Contacts) If the blocked person is already in your contact list, this is the fastest method.
You will see a list of all blocked numbers. To the right of each number, you’ll see a minus (-) icon or a trash can icon . Tap it.
That number can now call and text you normally again. You can also tap the “Add from Contacts” or “Add phone number” option in this menu to block new numbers. Method 2: Unblock via the Samsung Messages App If you blocked a number directly from a text conversation, it may also appear in the Messages app’s block list.
