Depends on the device and such You'll probably have to do some
configuration of /etc/ppp/ppp.conf, but if the device is supported it
should be doable.
It's an Internal Huawei 3G Modem, it works fine in OpenSuse 11.4 Milestone 6 and in Ubuntu 10.04 and 10.10, It gets detected when the text part of the Installer is working. I'll update when it's finished Installing everything.
