AT&T is at it again. In June of 2010, AT&T pulled the plug on its unlimited data plans and switched to tiered bandwidth plans. Now, AT&T is switching things up again – giving customers more megabytes per dollar, but charging more money in the process. So, which AT&T data plan is right for you?

Currently, AT&T offers basically three data plan options. You can get 200MB per month for $ 15, 2GB per month for $ 25, or add the ability to do hotspot tethering from a smartphone with an additional 2GB of bandwidth to bring it to 4GB for $ 45 per month. If you exceed the 200MB plan, you will be charged an additional $ 15 for another 200MB, while going over the limit on the 2GB plan results in an additional 1GB of bandwidth for $ 10.
