  1. How to get USSD to work ? Its not working in my device………….originally Optus branded unlocked router has no USSD settings.

    After webui update i have USSD on the menu but it doesnt work.

    Any idea???

  2. My device model is Huawei E5573Cs-609 and currently it’s running with WebUI ver. Unfortunately, it doesn’t have USSD support so I’d like to replace current WebUI version and possibly have to downgrade in order to get USSD function enabled. Please provide instructions on how to replace current WebUI ver. with another ver. which includes USSD functionality. Consider my device as already Unlocked so we can skip unlocking part. Also please suggest any another higher WebUI ver. (if available) with USSD support for this model…
