I got an iphone 5c, but I didn't realise it needed a nano sim so I had to cut my micro sim, I put it in and it worked fine but it says there's no service, I've changed all the service settings and I get signal for a few seconds but then it goes. And every time I try to call someone, it goes straight to saying call ended. Please help, have I broken it?!
