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.

After a lot for searching, I find these two project which aim to provide this functionality for Linux:

1- gsm-ussd :  [ http://linux.zum-quadrat.de/  ]
2- ussdq

I try them with my modem Huawei E1750 but without success unfortunately. If you have any other solution, please share it with us.
