Some brands require a few different unlock code based on the different locks that could be active. Huawei have however made this process very simple, with one unlock code being needed to remove the network lock. Bringing up the prompt to enter this unlock code is also very easy with Huawei phones. Most of their phones, and certainly their modern releases, simply require you to turn the phone on with an unaccepted SIM card inserted, the phone should then automatically prompt you for the code if it is locked. This is where you can get the unlock code, which can be sent to you by selecting the phone you have from the list and completing the order form.
