[arch-general] experience with gprs/umts cards & linux?

Hi, Unfortunatly i need to travel a lot recently. For windows you can use those pcmia cards that act as a modem for umts/gprs connections. If anyone tried something like that on linux, please share your experience. Maybe i could use a mobile with bluetooth as well. -- best regards/Mit freundlichen Grüßen Arvid Ephraim Picciani
