Very easy to order. Great price, better than direct with O2. Phone arrived next day as stated. Can't fault them at all. I got an O2 tariff. The only problem I had is that when trying to keep my current number O2 wouldn't activate the sim for me over the phone as it hadn't come directly from them. I had to go into an O2 shop for them to give me another sim directly from them, then swap my number over. Surely this can be changed as I see no point in Mobiles.co.uk or any other third party phone company sending sims out with their phones if the companies won't activate them directly. All very time consuming and a bit of a pain but all sorted & up & running now.
