No cell coverage
Ther is no cell signal in the park.
No, they do have a payphone at the rangers station though. And you can get service if you drive into Townsend, Pigeon Forge, or Gatlinburg.
I'm at&t I had no single at all but a very beautiful place to visit
There is signal, but as I was on vacation and don't live there, I dont know the carrier.
