It's a very good deal, and it's available to existing customers as well as new users, which is great (AT&T user here). But, a couple of caveats: 1) it's over 30 months, not 24 (Verizon's deals are over 24 months). So the per-month isn't as high as it seems. 2) it's only available on certain AT&T plans. I haven't called to find out which ones yet… but I'm sure it's going to be unlimited, and maybe only certain unlimited plans. I'm currently on an older family share plan with plenty of data and would have to go to a more expensive unlimited plan to get this.
