The issue happened with both an iPhone 5 & 6. The 5 was a couple of years old and I assumed it was just worn out. Now the 6 has the same symptoms. No send or receive text and no placing or receiving calls. It is also warm as if it is trying to do something. Searching settings and multiple on/offs and hard resets have not helped. In settings iMessage is off and it will not let me change it. On my iTunes account I went to my cloud backup and used it instead of allowing a backup from my desktop. This is actually 3 phones in 6 weeks with the same issue.
