Which cell phone is the most reliable in rural areas?

I am from the country. Have you ever heard of Yanceyville NC? I don't live there anymore but I go out there a lot because I have family there and I go to church there. I had a hard time looking for a cell phone in the past that was reliable in the rural area. When I switched to alltel http://www.alltel.com it works everywhere I go. I always get a reception even when I past all those trees and most of the time go over the bridge. That's the best service for me.

Wireless carriers in the United States operate over two different networks: Code Division Multiple Access (CDMA) and Global System for Mobile Communication (GSM).

CDMA coverage is very strong in the United States, particularly in rural areas.  The best phones to handle rural areas would be the The LG VX8350, LG Chocolate, VX8000, and the LG Dare are excellent. They will pick up signals in the mountains and other rural areas.
