I'm currently on a Vodafone SIM only contract for £15.50 a month, for which I get 600 minutes and unlimited texts. I'm using some bog standard Nokia. I've decided to make the giant leap into the world of Smartphones. I was going to buy a phone and keep on a SIM only contract but start paying £20.50 a month for which I'd get some MB (that's what I'd need isn't it?), however I've come across this contract with Orange which is available through Tesco. I'd get a free Galaxy S2, 400 minutes, unlimited texts and 250mb for £26 a month on a 24 month contract. Is this quite a good deal? Do I even need such a phone? I don't really know what I'm talking about so if someone could talk to me about it I'd be eternally grateful.
