My IPhone doesn't allow incoming or outgoing phone calls. Starts to dial then just goes back to the contacts screen I can receive messages and send messages BUT only to people with an Apple device. Please help.
A couple of things to try:
- Try forcing it off (hold power button and home button down for 10+ seconds) and back on.
Try removing and reseating the SIM.
Make a test call to customer service (611 in the US).
If none of the above work, you can reset network settings (Settings -> General -> Reset -> Reset Network Settings).
This is what any tech support (Apple Store, carrier) would have you do first.
