Hey all! Basically my boyfriend and I both have iPhone 5's running the latest iOS 8, but we seem to be having problems with iMessage lately. All of our messages on both sides have been going through as SMS for a few days now. I turned iMessage off and on on my phone, and that doesn't seem to have fixed it. I also tried to send an iMessage from my iPad Mini, but it failed and wants to try the SMS relay that I have enabled. It doesn't seem to make a difference whether I'm on wifi or LTE. My carrier is Verizon, and his is T-Mobile. iMessage seems to be working for my other contacts. I'm not sure about his, but it seems to be isolated to our Message thread. I'd rather not delete the message thread and start over if it can be helped. Any ideas?
