Even if we complete our SIM unlocking service, it will not help change any Network Block that may be in place (either enforced for just your carrier, or possibly your entire country). If you are the rightful owner of the device, get in touch with your network as they are the only ones who are able to unblock it. We will not refund you if you asked us to unlock a device that was stolen and it still doesn't work on your network.
The "No Service" message can also appear if there is hardware damage to the device antenna, which you are responsible for checking prior to ordering the unlock. We cannot refund if we complete our service and the device has issues due to hardware damage.
