I live in the Cincinnati area and have Verizon, I don't have as many problems as my friends on sprint or some of the other companies
one other thing to consider is that the local phone company, Cincinnati Bell offers a package with your home phone that includes their PCS cellular phone, it is a pretty good deal
if you are going to be traveling aroound in KY alot, you need to realize that just about everyones service sucks in most of KY except along the interstate highways, northern KY and the big cities have good coverage
