I am a cell phone noobie.....just coming up on my 1st year anniversary next month.
That being said, I use Verizon and am quite happy with it. While it didn't work at my parents farm in nowhere northern Minnesota, I could pick up reception when I got near town and that was great. I was in their extended service area (didn't have to pay any roaming charges). As for coverage here in the valley, it is great. Damn hard to hide from a good signal. Coverage along the freeway cooridores while doing intrastate travel is nothing short of amazing. And it works in Moab so we can call the kids while we are on vacation!
Can you hear me now?
