Well I'll have to admit I was quite sceptical when I saw the deal online with mobiles.co.uk, it was hands down the best I'd seen,and with three mobile trying there best to cast doubt in my mind I nearly didn't bother. Anyway I did and there was some issues with the delivery - not due to the service by mobiles.co.uk though, no, someone decided to steal the delivery before it reached me, being a bank holiday this led to some considerable delay. However despite this and the obligatory pretend hold to rack up the bill, customer services dealt with this in a timely and friendly manner, and even offered after my suggestion to refund some line rental and a free gift up to £20-25 from the car phone warehouse (although I have yet to receive this) as compensation for my hassle. I did have to source myself a new sim card from o2 though as they were unable to do that. So despite the initial delay I'm now sat here with my new, s7 edge and have all the credentials from o2 I would have had and paying less than I would've done from my old network three for a better service. Would I recommend mobiles.co.uk? In short yes.
