I think AT&T might change some of their other service prices. T-Mobile and Sprint have both been lowering their prices while AT&T and Verizon have stood strong, but eventually one of them is going to break and the other will immediately follow.
There is an especially huge gap in prices between individual and family plans right now. Family plans are so much cheaper. For example, $30/month for unlimited text across up to 5 people on a family plan, versus $20/month for one person unlimited text. Obviously the idea of the family plan is that it would be somewhat cheaper, but individual plans are pretty exorbitant right now, I wouldn't be at all surprised if AT&T dropped individual text rates or something like that.
