This service can provide the factory unlock code of all HTC device. This database can provide the unlock code of any network phone of any country. It is connected to HTC official database, hence we only need 15-digit correct IMEI to generate the unlock code.
Once order placed and code not found in this database, I will submit it to another server.
Newest HTC models from MetroPCS and T-Mobile USA do not ask for a Network Unlock code. They use “Device Unlock app” to unlock the device. You will not find any option to enter the code, so don’t place any order. Once code will come from the server, there will be no refund.
