We're having exactly the same problem in Kennesaw, Marietta, downtown Atlanta, and Hapeville at the airport. I was travelling the last two weeks and didn't have the first problem in Boston, MA, Richmond, VA, or Fredericksburg, VA using a Thunderbolt. We've also got a Razr and it's having the same problems in Kennesaw (no travel on that one). We've spoken to Verizon 3 times so far and they've already replaced the Razr, but it's still having issues. When I tried to tell them I hadn't had problems when travelling with the Thunderbolt, they didn't really want to listen to me and just suggested I replace the SIM card. It's getting ridiculous and it's TOTALLY not what I'm paying for!
