A word about carriers... Last July I switched over to Cingular after being on Verizon, or it's predecessor, since '98. I loved the coverage and what was then, freedom to mave from plan to plan at anytime, as often as I needed, without any financial penalty or renewed obligation (extending the contract). Well, apparently this freedom from contract restrictions was done away with over time by the high muckee-mucks at Verizon. I really loved this feature, in addition to good coverage everywhere excet in the most remote spots, or where otherwise blocked by things like mountains surrounding my position. Well, as I mentioned above, I decided to give Cingular a try. ...They're not bad, especially in urban and suburban areas. But they're coverage in the areas where I like to play with guns and various critters left me wanting. I'll be going back to Verizon just as soon as I can. I had cell coverage with them in spots where I never expected it. For folks of our passtimes and intrests, this is a very important feature, if you ask me.
I'm not that familiar with Alltel, they may share networks with Verizon or some other company. I know they are more of a regionalized carrier than some others, like Cingular, Sprint and Verizon. The FCC regulates how many carriers can be in a certain market or region. Most carriers have agreements with other carriers for roaming issues. Some charge, some don't. Alltel may even be Verizon, more or less, or some other company, operating under a different, more regional accepted name to justify higher airtime rates, fees, and to escape running afowl of monopoly regulations.
