In the area where I am AT&T is much faster than Verizon's 3G network.
I average about 3-3.5 mbps down and 1-1.5 up. My VZW mifi will get <1.5 mbps down and up!
To me, data speeds are way more important than an occasional dropped call so I'll be sticking with at&t.
Not only that as more leave att to join verizon, hopefully voicecall on att will improve. i will stick with att for now also.
losing internet because of a phone call so much reminds me of the dial up days. shuddering...
