T-Mobile Sidekick II works great, connectivity is fast, since browser load fast therefore GSM / GPRS is excellent in our area. Mostly of time inside building kinda low signal and some area like Ez Casino or Alberston, and kind of building without windows that cause no signal. Most of time where ever I go has Voice / Data here Harlem and in Havre, except between these two town which is Chinook has some coverage but only Voice, got to be outside and search for better spot for clear conversation and the signal strenght is too weak to have Data for this area. All major cities in MT also has coverage, Great Falls and etc along major highways. T-Mobile pretty much workable around / by on the road. (T-Mobile customer roam on Alltel GSM / GPRS network, therefore no T-Mobile network exist in MT as of yet, just patnership with Alltel)
