Im specifically referring to the credit checks involved. Do you basically just need a bank account and a permanent address or is it done on some sort or credit scoring ?

You will need a credit/debit card and a permanent address ,this is becasue if you try and cancel the contract the contract stipulates they can charge you upon cancellation 12(minus how many months you have had it) months of monthly line rental

The credit check is usually done by credit card. You give them the card, they charge £60 to it, wait for it to be authorised, and then refund it.

I don't know whether I'm allowed to do this or not, if not I apologise to Digital Spy but there is a good site by the 'Which' people to help you decide what kind of contract would be best suited to you.
