I still have an old AT&T contract with unlimited data. I don't really use that much data relatively speaking, so last time I was up for renewal I tried several times to see if I could get a cheaper plan from AT&T, and no matter what I did it was always more expensive than just keeping my current unlimited data plan because they've raised prices on everything else. So when this iteration of the contract is up, if my only options are going to be something more expensive, and they're not going to subsidize my phone anymore, then that rather lowers the chance that I'd stick with AT&T.
