Like that mention of Alltel providing GSM roaming in ND, I had coverage from Unicel in Jackpot, NV (just south of Twin Falls, Idaho) about a month ago. They are now part of Verizon, so are presumably not a GSM company, but just make some roaming income by putting GSM on their towers.

BTW, apart from Reno, I haven't found anywhere else that the Simple Calling will roam on 3G. I wonder what is different about 3G in Reno?

Alltel used to be GSM and switched to CDMA, which Verizon later bought out. Alltel never converted all of their GSM towers over (likely because they could make money off roamers in areas that have no other GSM coverage).
