iPhone not calling contacts in contact list
Hi,
All of a sudden, and out of the blue, my phone has stopped me being able to call people that are already saved in my contact list. It says 'you have dialled an incorrect number' when attempting to call.
It does however allow me to call people by typing their number in to my keypad. It also allows me to receive calls from people in my contact list, but it does not state their name, and only states the number they are calling off.
Any help would be brilliant!
