Huawei, ZTE, Micromax, Alcatel, and Novatel are the popular 3G/4G modems/router providers globally. Huawei had earlier launched Huawei B260A, B960/E960, and B970 routers in various places and cannot be unlocked with simple software for unlocking USB routers like card lock unlock tool, Huawei modem code writer tool, etc. This software supports only USB routers/modems, and it cannot detect the LAN port. Hence, Huawei B260A, B960, and B970 routers cannot be unlocked by this software.
But, Huawei B260A, B960, and B970 Routers can be unlocked with FMC UnLock software (download link is provided at the end of the article). If your Huawei B260A, B960, and B970 routers have un-customized firmware, create a LAN connection between PC and your Huawei B260A, B960, or B970 router; and then run FMC UnLock software.
Now click on the Detect Device button, and it will replicate the IMEI of your Huawei B260A, B960, or B970 router. In the password field, put NCK / unlock code of your IMEI and click on the Unlock button (it will be highlighted only after detecting the IMEI of your router/gateway).
Note: Make sure that you have disconnected from the internet and closed everything related to your Huawei B260A, B960, and B970 routers.
