I have an iPhone 5 running iOS 7.1.2, I recently turned off the iMessage and FaceTime and then ejected my SIM card and inserted SIM card of another network. After few hours I again switched my SIM again to previous network.
After that I am trying to activate my iMessage and FaceTime but no luck. It is not displaying my number in address. I checked my number in Phone but there my number is correct.
I have tried network reset, phone reset, hard reset, turning on and off both services but no luck. How do I go back to using FaceTime and iMessage on my original network?
