Huawei has recently launched the E8372h and E8372s 4G LTE wingle. If your E8372 is locked to a particular network and can not use any other network provider SIM, you must want to unlock it. Unlocking is simple and one-time work.
If your device is Huawei E8372s, then change the default SIM with another carrier SIM card and plug it into the PC. It will automatically redirect you to the unlocking page and will ask you for SIMLock / unlock code. Just enter the correct NCK / unlock code in the box and click on OK; the device will be unlocked permanently.

Firmware / WebUI / Dashboard changing is risky, and may it dead your device. The firmware update program may ask you for a password. Generate the firmware code from the universal master code tool and use it as a password while updating the firmware.
Note: Don’t try to use the unlock code generated by universal master code software. It generates old algorithm code and does not work with Huawei E8372h and E8372s devices.
