Mobiles.co.uk had the best tariff price i could find for the phone and network I wanted (Samsung Galaxy S5 on O2). When I put the price to my existing network (Orange/EE) and other service providers they could not come near to the price so Mobiles.co.uk were very competitive. The ordering process was very straightforward and didn't take too long. The delivery date that I was given wasn't met, and when I logged on to mobiles.co.uk to use their order checker it just said that my order was processing, even though I had an email to say it should already have arrived. It only took a few additional days to arrive and I am in Northern Ireland so that may have been the reason. When the phone did arrive it was in perfect condition.
