MY phone was fine today. Then all of a sudden it said invalid sim. I tried resetting the network setting and turning off airplane mode then on, nothing. Turned phone off then on. Nothing
iPhone 5, iOS 6.1.4

Q: Invalid sim on iphone 5. Any ideas
Try cleaning and reseating the nanoSIM. If that does not work then replace it.
