Go sprint, cheaper plans, and pretty much the same coverage (unless you live in the sticks, then go verizon)
Sorry i work at Radioshack, and im bias to the carriers i have, but sprint, is truly underrated.
Im getting the epic 4G next pay check, and uber cheap dealer line, but yeah, a single unlimited everything line is $80/ month, 500 mins, something like $50-60 i think?
