Yes and no, the maps I saw were not that good, BUT what I found was this that was better for specific spots to start with and another map that was excellent in the same way. In the link pop in your area code and it shows who is using what bands in your area. I will if I get time try to find the other map later. It showed the area and in color who owned what bands. In Virginia most of the north ATT has the 850 bands, but in the southern part of Virginia, Alltel owned 1 and Verizon the other half of the 850 band, so when Verizon bought them, they got it all. So ATT can only transmit on 1900.

Didn't take long
http://www.cellularmaps.com/regions/ Click on your area and go from there. This shows who OWNS the license to the frequency which is very important, as if you don't have it now, if they don't own it you never will.
