Especially with the strange way they sell it at the moment. In vodafone you cannot get 4G without going for the highest price plan for example. (or at least that was the case 2 months ago) Which may make sense to them, but for the customer that's a bit silly. They will actually use different software in samsung phones, so that if you buy a S4 on a lower plan, it's not capable of connecting to a 4G network.
