I had AT&T. Their service sucked at my house. And most of my town. So I switched to Verizon. FULL BARS at my home. 3 years later to now. They changed their tower configuration (the tower is -2mikes from me) and now I get 1-2 bars. Marginal at best, and Verizon support even said that. My service went from great to sucky. I am pissed.
