Alright so to you guys that think AT&T has the right to force you to have a data plan if you have a smart phone really don't know what you are talking about. Sure there may be no law against what AT&T is doing technically, but they may be breaking some FCC rules and nothing is being said. Lets look at the thing about AT&T not letting unlimited data users to use FaceTime over data and tethering. A company decided to look into this and see if it was ok for them to be doing this. Well come to find out it is not and the company has taken the FaceTime to the FCC and now on the iPhone 5 unlimited data users can FaceTime over LTE. I have the iPhone 5 and have tested it and it does work. AT&T never said anything about cause they don't want you to know, but it does work. I am not sure what the name of the company is that is going after att but it seems to be working.
Just because AT&T does something does not mean they are allowed to. About 5 years ago you could own a smartphone without data. The problem is the right people are not complaining to the FCC or AT&T and nothing is getting done. OP if you want to stay with att I would call them and complain and see where that gets you. For those that said you signed a 2 year agreement with them, I don't ever remembering reading anywhere on the contract that I had to have a data plan if I had a smart phone.

Here are the groups that are going after AT&T:
"This brought plenty of criticism from consumer advocacy groups like Free Press, Public Knowledge and New America Foundation. These groups claimed that AT&Ts actions violated net neutrality laws by forcing their customers into plans with fewer options and less data."
