Airtel Nigeria offers a customized Huawei E5336BS-2 router, and you can not unlock it using only unlock code. When you change the Simcard and log in to the device, you will be redirected to the unlocking page, where you will find zero (0) attempts to enter the “unlock code/simlock.” Since all the attempts are already exhausted, it is impossible to open it for all other networks.
However, if you change the default firmware with universal firmware, you will again gain ten attempts left to enter the code. That means unlocking, but before that, you need to change the firmware of your device.
