I suspect that the phone which you are using is SIM locked and hence you are facing such problem. Usually the phones which are SIM locked cannot detect the SIM card other than the SIM card which has been allowed to be used. If any unsupported SIM card is inserted in the phone, such errors will be faced. Therefore I would suggest that you check if the phone is SIM locked or not and then go ahead with different troubleshooting procedure.
