What is the difference between iPhone 4S ATT and Sprint?

I have Sprint iPhone 4S the unlimited plan. I'm paying $84 for one line.Am I getting ripped off, i don't know. Its the not the same for ATT but I have 3G. What's The difference of Sprint and AT&T in my situation for what I'm paying.

I don't think you are getting ripped off. I have Sprint and an unlimited everything plan including 4G will run you around $130.00 or so after taxes were included. I also had international and a few other odds and ends.So, if you switch to Sprint and go with unlimited minutes and data and the mandatory 4G upcharge you will pay more than you are now at AT&T.

Go to www.sprint.com and compare your plan.

AT&T is a lot more expensive, I have it! It's about 150 a month for me. I get charged $10 for going over my data, and for going over my minutes. You should stick with sprint, it's the better deal

Manuel_JRojas, This is a great question that I would like to figure out as well!
