Modem Manger / GUI is not expected to work for all 3G dongles out there. You might want to use the software developed by the manufacturer of your dongle to use the USSD feature.

For Huawei dongles:

Huawei Mobile Partner

enter image description here

There is a higher chance that you can find the Huawei Mobile Partner available inside your dongle.

If you don't have the it with you, heres how to download and install it:

Installing Huawei Mobile Partner 22

  • If you don't have Internet to the host machine, first click here & download the Huawei Mobile Partner 22 to your Home directory. Then execute the below command in Terminal:

     tar -xvzf megafone.tar.gz
 cd mp22-linux-64
 chmod +x install
 sudo ./install

  • If you already have Internet to your machine copy the below command into the Terminal at once and execute it:

    wget -O mp22-linux-64.tar.gz https://db.tt/XtrP9KPw
tar -xvzf mp22-linux-64.tar.gz
cd mp22-linux-64
chmod +x install
sudo ./install

If your dongle is not detected by 22nd version of mobile partner, you may try installing 21 or 23.

If you have a Prolink or ZTE dongle see ZTE mobile connect section from here.
