I can't seem to make calls or receive calls all of a sudden. I checked my payment and it has gone through, so it's not an unpaid bill issue. How can I resolve this?
incoming and outgoing texts work. It's just phone calls that are not coming in or going out. As soon as a number is dialed, it disconnects. Tried rebooting the iPhone and removed sim card and re installed it, still nothing. What can I do next?
