Girlfriend's Tour Won't Dial or Recieve Calls

So my girlfriend's tour will not recieve calls or dial out while at our house. When in a city it works fine. Granted that we do live in a really rural area and cell coverage is limited at best. The problem is that my Samsung will show 1x with no bars and Her Blackberry will show 1x with 2 bars while side by side in our house. I can Call her and my phone will dial out but hers never recieves the call... 3 rings and then Voicemail on my side... Samsung works while Blackberry doesn't... Oh, messaging works ok on her phone just not phone calls

You can try updating the PRL on your girlfriend's phone. That might improve her reception at your house. Dial *228 and at the prompt, select Option 2 to update her phone's roaming capabilities.
