Sim is not use al network sim is not allow

Your question does not make complete sense, but let me try. It would seem that your phone will not allow you to use the SIM you have. Is that the case? If so, then it would appear that you have an iPhone that is locked to a carrier that is not the one you have a SIM for. If the iPhone is locked, then you need to use a SIM from the carrier it is locked to. Only the carrier that has the lock on the iPhone can remove the lock.
