I had AT&T for over 10 years, traveling for work on the east coast it worked, but at Powell I never had reception when friends with Verizon did. Changed to Verizon 5-6 years ago and couldn't be happier. We even managed to log in and work remotely from the front deck of the houseboat in the Halls buoy field the last few years with VerizonI had NO cell service or G-anything down in Stanton this week with my new ATT service I-Phone 5. I know it is old technology, but is new and failed to preform. It was quite relaxing.
P.S. my old flip phone, with ATT worked great in Stanton. Sq
