My wife and I were on vacation in Lake Placid, NY. This location is somewhat remote, but certainly not isolated. We were doing some shopping separately along Main Street. She has Cingular coverage and I have Verizon. After several hours I called her cell phone to find out exactly where she was so we could meet for dinner. My phone had coverage although the call went directly to her Cingular voice-mail. I then searched several minutes for her and found her in a store a couple of hundred yards down the street from where I had been. Her phone had been on but she had no coverage at all, which is why the call went directly to her voice-mail. We travel a lot and we run into this problem with no Cingular coverage a lot.
