Going to be buying the iPhone 6 64GB unlocked and going with a decent sim-only plan on this, probably three's £15 unlimited data, 200 minutes plan. EE is getting wifi calling, but I'm not sure whether to go for that when the data offering is worse. Maybe they'll give me a discount as I'm on Orange at the moment. I can also get 20% off Vodafone through work, so that's an option. Hmm. Will have to do some research.
