Yep, I saw that one, but it's specifically for Sprint and EVDO cards. There's a UMTS version available in Europe, but that may not work with Cingular cards. The cards are designed to be serial ports and require the correct ATD command, login, and passwrd information to work.
A guy camped next to Dave at Las Cruces mentioned he was using a router that accepted an air card. I didn't pay a lot of attention to the brand of router or air card service, but Doc did. Next time you talk to him, ask him for the info.
After several calls (linksys, cingular(3) ) cingular agreed it will work. linksys says the "Option 3g card" will work (only one that cingular sells that is compatable with this router. It will be at least a month before I try and set this up. The advantage to this setup is largest mobile area in the US plus being able to use while in route.
I've got the old Verizon card but don't use the dang slow thing. Have cable here at PEM Only trouble is when I go to the Q is finding enough cable to attach to the MH as I motor toward tje Q, before I go broke.
