To unlock the Huawei B315s-607 router to use any SIM card, you typically need to update it with "universal" or "mod" firmware. This process allows the device to accept network configurations from other carriers. Unlocking Methods

1. Download the older firmware (e.g., version 21.318).
2. Run the firmware update .exe file.
3. It will detect your router via the LAN connection.
4. Do not interrupt the power. Let the update process complete. The router will reboot.
5. Once rebooted, log in to the WebUI. If the version number is lower, the downgrade was successful.
