Your sim either went bad, they do that, or its disabled. a simply way to test it is to put the sim card in another phone and see if you get the same message. if you do then you'll need to get a new sim card, which means all your stored contact information on it is lost, but they are still on your phone, well most of them should be, all depends on how you stored your information
