I live in Saskatchewan but I'm in eastern Montana quite regularly.

I noticed last month that service in the eastern strip of Montana has been turned off (e.g. Plentywood, Culbertson). I checked with my Canadian provider and they advise me that AT&T turned down service on October 7.

What's happening? Presumably someone is taking over this service. AT&T phones (and phones with networks that normally roam on AT&T here) are simply showing No Service in this area now, which is quite annoying.

Nemont (Sagebrush Cellular) is as far as I know the only provider in the area now and they use CDMA.

Any info?
