i find it impossible for verizon not to have an unlimted data plan.
I don't. They offered it at one point, and the US is one of the few last countries to offer any sort of unlimited plan for a long while. At some point I saw it coming... AT&T followed, T-Mobile offers unlimited but throttles you starting on how much you pay 200MB, 2gb, 5gb, or 10gb. Sprint offers unlimited while on their network, and if you end up roaming you only get 300MB before they terminate your data plan for the month. Do it enough times they'll terminate your contract. When they start rolling out their 4G I expect them to drop the unlimited data plan themselves as they already did it with their internet cards.
