The issue I have is that the marketing materials rarely seem to capture those nuances. And that seems kind of scummy to me. http://www.t-mobile.com/cell-phone-plans/individual.html# http://www.t-mobile.com/cell-phone-plans/individual.html# As an ex-T-Mobile customer, I will completely admit they do a passable job of information (especially compared to other carriers). I think mostly because they take the saner business strategy of "limited 4G + unlimited <= 3G". But the phrase "unlimited data" still appears an awfully lot on that page, without a lot of caveats... Unlimited data isn't unlimited if they limit the devices you can use it on.
