I'm brand new to ubuntu and linux. We access internet from a usb stick issued by a local telephone company. When I plug the stick into the computer, I see the device listed under internet connections as a mobile broadband device but it is grayed out and inaccessible.

I tried to create a new mobile broadband connection but my country (Gabon) is not listed and we have no payment plans per se (we pay from a pre-paid card system)..

Any clues as to how I can get the system to recognize the internet connection?

Thanks for any help...
