C.O.
D.,
I have Verizon because of their coverage and where I go AND because my family (dad, sister, brother, etc.) are on Verizon.
We tried T-Mobile - my husband couldn't get service in our metro tunnels. Verizon did. We tried AT&T - coverage sucked at the time as well as the rates.
Now? TODAY? I don't know if I would change or not. There's a lot to consider - phone, coverage, cost, etc. If you are looking for a temporary plan? then I would go with a pay as you go. If you need a phone like I do for business? Go for stability.
