Hi I've just upgraded my Mums phone with Vodafone to an iPhone 5s. She has got it for £37 a month 1gb data, unlimited txts and minutes. The handset was free. I have a couple of questions though, will it do 4g and could I have got her a better deal. Since upgrading my sister had claimed she was offered the same phone and plan for only £28 a month. I personally don't believe her and Vodafone confirmed they would never offer this handset and plan for that price. What do others think? Could I have got her a better deal? Cheers.
