I am new to linux OS. I have connected d-link USB data card to my laptop and I can connect to internet with that using mobile broadband connection. but how can I check my data balance ? I mean USSD Code. I have tried both modem manager GUI and prepaid manager app.
In Modem Manager
See.. the modem is listed.
but in info tab
And when I try to run USSD code
Please help me. I have tried a lot of methods from askubuntu and other sites. no result.
I just only want to run ussd codes.
