To apply the code, you usually insert a "non-accepted" SIM card into your Huawei device and connect it to your computer. When the management interface opens in your browser, it will ask for the unlock code. You enter the "Unlock" or "v201" code provided by the calculator. It is vital to remember that most devices only allow ten attempts to enter the code correctly. If you exceed this limit, the device may become permanently locked to the original carrier.
