I was just talking to a guy last night who's job is working in the mobile data speed business. He said it's all a bunch of semantics at the end of the day, because even if a company says they will provide an "Unlimited Data Plan", they will severely drop the speed of a user's connection once that user goes passes a threshold of data that would be considered excessive. So no matter whether you are on an unlimited data plan or a plan with a predefined amount of data included, you're going to basically get what you pay for in the end either way.
