There are a few ways to tell if you’ve been blocked on your iPhone text message. The most common way to determine if you’ve been blocked is to check the “Block Blocked Messages” option in your settings. If this option is not present, then you may have been blocked for some other reason. If the “Block Blocked Messages” option is present, then your phone has been blockaded and you will not be able to send or receive text messages until it’s unblocked.
