Well, verizon just recently changed their network where there is no longer any roaming charges. And if you look at their coverage maps, the all-digital rate area, is just as big, if not the same size as their entire network including the AMPS (analog) which verizon has almost completely wiped out. I travel with my all digital phone (Samsung SCH-A670) all the time, even in what I would consider rural areas, and I have never been off of verizons digital network. Plus the anolog signal is crap. It completely draines your battery. There is an area in virginia that I drove through a year ago with my old tri-mode phone, and it went into analog mode. I drove through the same area two days ago and the signal was full strength and completely digital. I hope this answered your questions.
