Wireless service for traveler

I'm looking for a reliable wireless service that will operate in the Vicksburg area of Michigan (49097), plus have coverage for traveling which would include Las Vegas, New Orleans, Boston, Nashville, and West Palm Beach. I currently use Verizon out of Grand Rapids, MI and it has been an outstanding service. The only place it hasn't worked is Elizabethtown, KY. The problem is I can't get digital service in Kalamazoo and I've purchased more batteries and battery chargers than I care to count and all my customers in the Kalamazoo area have to call long distance through Grand Rapids. I would like to find a digital service for this area as well as decent nationwide service. Any ideas? I keep seeing advertisements for Voicestream, Nextel, CenturyTel, etc., and they promise you the world, but I don't want to jump until I get some personal input. Replies will be very appreciated.

 

Jack, thanks for the reply. We'll drive to all except Las Vegas and beyond. For that we'll fly. We have kids and grandkids on the East Coast and my dad is in Florida. It's nice to have a car to tour the areas.

Thanks for the reply. Trying to choose a wireless company is like shooting in the dark. The local Nextel dealer was a little wary about coverage in my town, so he gave me a phone to try. The coverage was decent, but their phones tear up my hearing aids. TMobile says they don't have coverage in my area. People who have had Sprint around here tell me to avoid it at all costs.
