well i guess all my travels in the U.S. have been in major metropolitan areas, but ive had zero issues with my WiMo phonesATT's coverage isn't as good nationwide - not even close for 3G which is vital for a smartphone and while I had users (sample size approx. 100 nationwide field reps some of which were in Canada, Mexico, Guam, and Puerto Rico too) on their networks we had far more outages than Verizon. Some carriers might be better in select local or regional areas on voice, but nevertheless, ATT isn't nearly as good for smartphones in the US.
