I gave up on iMessage with iOS 7.XX and decided to give a try again with 8.XX. I'm experiencing the same problems. Some texts I send don't get delivered (I received error messages with do I want to send as a text), I don't get some messages, etc. My husand has the same problem. I've turned it off again on my iPhone 5 and my IPad Air 2. Missing receiving texts or people not getting mine won't work.
Am I missing something?
