When a carrier sells a router, they install customized firmware that includes their branding, configuration settings, and a SIM lock. This lock checks the IMSI number of the SIM card inserted; if it doesn't match the carrier's database, the router refuses to connect.
There are generally two ways to remove this restriction:
For the B311-221, Firmware Flashing is often the most effective method because it also removes carrier-specific limitations on features like VoLTE or changing APN settings.

⚠️ Warning: Flashing firmware carries a risk of "bricking" your device. Proceed at your own risk. 1. Identify Your Hardware Version
Check the label on the back or bottom of the router. Ensure the firmware you downloaded specifically matches the B311-221 model. Using firmware for a B310 or B315 can permanently damage the device. 2. Install Drivers and Tools
Install the Huawei Mobile Partner or standalone Huawei USB drivers. Restart your computer to ensure the drivers are active. 3. Enter Download Mode
Most Huawei routers require a specific "boot shot" (shorting two points on the motherboard) or a button combination to enter the mode where it can accept new firmware. This usually requires opening the device casing. 4. Flash the Firmware Open your flashing tool. Select the B311-221 unlock firmware file. Connect the router to the PC via USB. Click 'Start' and wait for the "Success" message. Troubleshooting Common Issues
Device Not Detected: Try a different USB port or replace the cable. Ensure drivers are visible in the Windows Device Manager.
Firmware Incompatible: This usually happens if the "Hardware Version" check fails. Double-check that you aren't trying to flash a branded firmware over another branded one without a "transition" file.
No Signal After Unlock: You may need to manually configure the APN settings for your new carrier in the router's web interface (usually 192.168.8.1). Is it Legal?
In most jurisdictions, unlocking hardware you own is legal. However, it will void your manufacturer's warranty. Always check your local laws and the terms of your contract if the device was provided on a monthly plan.
💡 Final Pro-Tip: Always backup your current configuration and NVRAM (if possible) before starting the unlock process. For the B311-221, Firmware Flashing is often the
