For the last 15 years, I have been a loyal customer. I always thought people were crazy for using any other carrier. Verizon is more expensive than any other carrier but the coverage area has always been superior, until about 6 months ago. Little by little the dead spots have grown bigger and bigger. What used to be a quick drop and back to work, is now mile after mile of dead zone. It's getting closer and closer to my house so I'm lucky to have wifi calling there. My zip code is 37876 - Boyd's Creek Hwy, Sevierville, TN. I'm checking into other carriers, I just want to be able to conduct business on my 2-hour drive to and from work! If the answer is that you have too many customers on the network, I'm about to make it about six fewer. Maybe my neighbor's signal will improve when I'm gone.
