If you are a Dialog Broadband user in Sri Lanka (or any other region where this specific variant is sold), you have likely hit a frustrating wall. Your Huawei B310s-925 router, purchased from Dialog, is network-locked. This means you cannot use a SIM card from another carrier (like Hutch, Mobitel, or Airtel) without first going through a complex unlocking process.
- Download the "Universal Unlocked B310s-925 firmware" (often labeled

- Follow the tool’s instructions to read unlock code or perform an unlock operation via the modem’s COM port.
- Alternatively, if the firmware includes SIM-unlock, the device should accept other carriers’ SIMs after flashing.
Why choose this? No brick risk, retains original signal performance, and is legal.
