I use my cell phone to connect, try looking for the username and password for airtell (on my netwrok you have to xyz for both no matter what). Also is the number you'r dialling correct? Most providers need you to dial something like #8#1234#2 or something like that.

Wouldnt hurt to search for compatibilty of your specific card cuz a lot of gsm modems basically refuse to work under linux (SPECIALLY the generic ones in my experiance anyway)
