I travel all over the state and southern indiana, had ATT, Okay in Indiana but was not as good as Verizon in the boonies of KY. Bluegrass Cellular lets Verizon use their towers which is helpful down on Barren River Lake and such. When I had ATT, I had to walk outside my home office and into the backyard to make calls, I live in Beechmont pretty near the Airport and Watterson, which isn't exactly out of town.
