If you could get ANY two cell phones on ANY two carriers for maximum terrestrial coverage in the United States, what would they be? I would think I might be inclined to go with one Android and an iPhone. One would be Verizon and the other would be AT&T. I realize that a satellite phone would give better wilderness coverage, but I am referring simply to cell phones for this discussion. Anyway, would anybody here go with Sprint or T-Mobile? Or, would anybody go with a phone other than iPhone or Android?
