Well it is either a problem with the SIM card or the phone. First you should test out your SIM card.
Put the SIM in a friend's phone. If you put the SIM card in this other phone but it still says insert sim card, then it is the SIM that is no good. If the SIM works fine in the other phone, it would be the phone that is the problem.
