Unlocking by code Huawei
This service is used to remove a network blockade from all Huawei models. To generate an unlock code, we need an IMEI number which can be found by dialing *#06#, or by checking in the phone settings.
Unlocking process doesn't interfere in the system, so it is safe and easy for your device.
In order to unlock the device the customer receives from 1 to 4 unlock codes separated by a comma.
The codes include:
NCK - NETWORK code used for removing the main network blockade.( the first one )
SPCK - Service provider code or subset Unlock PIN used for removing the blockade from a subset network( like tesco in the UK), the next two codes
The last code is used to reset the code counter if somebody has entered wrong codes too many times in the device. When phone asks for "simlock block unlock reset key" the last code will allow the user to enter the unlock codes again
