All mobile phone contracts will require a credit check, this will be done by the registrations department of the service provider eg orange. They will get a score back and then that tells them how good a customer your likely to be, Orange use equifax and experian. You will have to have one done if you want a contract phone, nowt to worry about.
Please bear in mind that every time the companies to a credit check on you the score goes down, so if you fail a credit check with orange your likely to with voda etc and each time you try it lowers your credit rating so dont go from shop to shop
yes thats exact, they just tryed orange yesterday and it failed was in today for a couple of hours

and the only 1 that passed me was 3G but what they had to offer me was aloud of rubbish and could only pick from about 5 out of 100 phones, the way to get around it is to take out a sim only contract for 6 months and after 3 months upgrade to a contract, the reason i wanted a contract was to get a new decent phone as the 1 i have got is broke. does anybody know another way around this?
