My boyfriend has two numbers blocked on his phone so they cannot text or call his phone. If he downloads the new Verizon Messages app, does that mean that there is a possibility that they or he could message them through this app? Any ideas?
Your bf can message the blocked numbers; only incoming messages and calls are blocked.
Since the Messages app is linked to the phone number, my guess is the messages would not come through on the app either; he can still send a message to the blocked number, but replies will be blocked.
