I use Pantech modems with Debian ARM linux for real-time vessel tracking.

Linux can use the cdc_acm and ppp kernel modules to drive many of the USB modems on the market. You may need to compile these modules depending on how stripped your embedded platform is. Alternatively, you can use a turnkey system like a Raven or MultiTech, but they draw much more power.

Avoid USB modems that have additional hardware such as SD cards. These modems require specialized drivers (many unavailable in open source) to peel away the non-modem hardware layers before exposing the actual modem.

Thanks, I have bought simple E220(Huawei) USB modem. It is supported by default on linux. — emblinux, May 05 '12 at 11:24

Use a modem that is supported by ModemManager, an OpenSource project that is in many major Linux distro's, no need to reinvent the wheel!
