Lightspeed EDGE-100M GPRS PCMCIA Card on Linux
Google doesn't know how to set up this card on Linux yet, so...
I use Ubuntu. Debian uses the same structure for pppd config files. Users of other distributions may have to adjust some things.
Here are the PPPD configuration files that work for me. They may contain some unnecessary things, but at least they work.
Substitute providername with any name you like, 1234 with your PIN, and apn with your GPRS APN ('banga' for Bite GSM users in Lithuania).
