Huawei's newest Internet devices cannot be unlocked by simply entering an unlock code, like previous models of Huawei Internet modems and routers released before 2014. Therefore, the unlock codes of algorithms v1, v2, v3 (201) are useless on these devices. A new and different version of the algorithm is installed on these devices, i.e. Algo V4 (2015). Unfortunately, there is currently no direct unlock method and/or a direct calculation of this algorithm is available. Therefore, to get the unlock code for these devices, a complete process is performed, after which you can connect any SIM card to it.

The archive contains detailed instructions for obtaining all the necessary data for unlocking, and accordingly the NCK code!!!
