How to Unblock a Phone Number on a Samsung Device Whether you’ve accidentally blocked a friend or have decided to give a previously restricted caller another chance, unblocking a phone number on a Samsung Galaxy device is a straightforward process. You can manage your blocked list directly through the Phone app or individual contact settings. Method 1: Using the Phone App Settings
If you can call the person but aren't receiving their texts, you might have blocked them inside the Messages app rather than the Phone app.
If the issue persists or if you're dealing with a device that's locked to a carrier, you may need to contact your carrier or Samsung support for further assistance.
