Can I just confirm which 3G Dongle you are trying to use. The necessary steps to get a 3G broadband modem working (depending on model) are:
1. Make sure the Firmware is upgraded to V70.
2. Make sure drivers for the E220 modem are installed (they contain some necessary software which is used by later drivers).
3 .Make sure the E160G / E169G drivers are installed.
4 .Follow the setup guide for the operator you are with from
