Question about Cell Phones
Invalid SIM and Unregistered SIM are two different problems. Invalid SIM means the phone is locked to a certain company and you are trying to use a SIM card for another company. Unregistered SIM means the SIM card you are using is not active and you need to contact your service provider to get it activated. In order to unlock the phone so you can use anyone's SIM, you must contact the provider that the phone is locked to.
