I posted a follw-up to your question in the Ubuntu forums. Try the faster 3G service first man, it is not a pay service. I use my minutes like everyone else does. The slow service is just that....slower! I guess the qnc service will work on non-verizon towers when you are roaming -- mainly because the tower does not have the equipment to offer digital data services??? Don't know man, but try the 3G before messing around with qnc settings...
