Taking advantage of AT&T's promotion: 2GB to 3GB for same price (exp. 11/15/2014?)

AT&T is offering 3GB of MobileShare data for the $40 price of 2GB - part of a price battle with Verizon. It’s the default for new customers, but existing customers can get it by using the web site as though changing data plan. This is what I saw on that screen:

If you do this be careful not to miss the Submit button on the final screen, it’s lost below the formal fine print agreement.

Based on my reading and what a rep told me, there’s no known catch and no contract. Since Emily and I routinely use 1.9 GB I considered going to 1GB and paying the overage fee, but there’s no new discount at the 1GB level.

AT&T used to charge us $15 for an extra GB when we occasionally exceeded our 2GB limit, so this promotional plan should save us $45 a year — and we don’t have to be quite so obsessive about our iPhone data use.

I’m not sure how long this offer will be in place, the fine print says you have to make changes before November 15, 2014:

We don’t have any contract with our MobileShare (all our iPhones are unlocked), so I’m less worried now about AT&T treating me badly. I can leave at any time.

The change was applied immediately. Instead of 1.8 GB left this billing cycle we have 2.8GB.
