The providers don't want you to have a data only plan, because they stand to lose far too much money by allowing that. As it is now, they can cash cow you to death and get away with it because you have no choice. If that changes however, we could see them possibly go to an advertising based model like Google as well. Which, honestly, if you were required to look at an advertisement or receive advertising texts or something like that every time you did something, then I say, bring it on. I'll just set my volume for texts to off, and let them have their fun.
