I have AT & T and generaly have good service. But if I am drifting a River I.E. The Sandy or Kalama It is rare that I get service. On the Kalama once I get to Modrow bridge going up service is gone. Same on the Sandy Drift from Oxbow to Dabney, will finally pick service back up about 3/4 of the way down.

Up hunting I can get service once in awhile if I am on a ridge top or something. Generally it is something that surprises me while driving to a new spot, the phone will ring.

I am happy with AT&t Overall though. The places I don't get service are the places I don't need service
