Text messages bouncing back
I text this person everyday and I was in the middle of texting him when my message bounced back with (Edited as per community guidelines) number saying he had an invalid number. I can call and send pictures to him and that's it. I can receive his messages and I can text other people. He can also receive messages from other people so I'm not sure what the problem is. I cleared my cache and data but the problem is still ongoing.
