Which cell phone has the most reliable signal in rural areas?

I can only tell you from my own experiences that my cell phone which is a Nokia and my provider which is Sprint have been phenomenal when it comes to getting a signal. I have perfect signals in mountain areas beaches on boats, inside my home and I actually think I can tell you the only and I mean only area that we have signal problems in near my home and it happens with any phone in that area. My phone is the Nokia 2760 which ia a basic phone with camera and ability to email and text with all the data options included. It really matters on your provider to get the great signals. They should give you a map of calling areas they have and on it should signify blackout areas that are known to have poor reception. Sprint is awesome that Is all I can say! I added some phones that are rated high below and come with affordable prices as well. Enjoy!
