I have AT&T. Two phones with 700 mins, 2 gb data and unlimited texting is 180 a month. Sprint is unlimited everythi ng for 100 a month. The only not unlimited thing is calling land lines. You get like 400 mins a month for land lines.
Verizon is so awesome never had an issue. I unfortunately for now am locked into a contract with t mobile and hardly ever have a good signal anywhere. Got it for the free phone...regret it. Nothing but issues and never had better than a 2g. Only plus its cheaper than most contracts....wish I had stayed with Verizon.
