Cell Phone Providers in Iowa
I would say Verizon, US Cellular & AT&T Wireless are the most popular here. We also have Sprint, Nextel, T-Mobile & Cingular (maybe others that I'm forgetting?). I guess it depends on where in Iowa you need coverage to decide which carrier you want to go with. I know that Sprint and T-Mobile only have good coverage along the interstates, not anywhere else.
We currently have AT&T and are not that impressed with their coverage outside of Des Moines - about an hour out of the city in any direction and we have no signal. US Cellular and Verizon seem to be pretty good, though. I think most companies have local, regional, and nationwide plans. I would think Minnesota would be included in some of the regional plans. (But it is not included in our regional plan with AT&T.)
