How do you do USSD queries for 3G modems in Linux? for example if you want to know your balance, you press "*100#". In Windows most of manufacturers of 3G modems (like Huawei E220) supply a spacial program for USSD queries but that not an option in Linux.
Myself, I always disassemble my 3G modem, remove the SIM card, put it in my mobile, do what I need and then reverse the whole procedure. It is not fun. Therefore, I start looking for a solution.
