Sorry to sound like a doofus, but I'm just a PAYG user, so just wanted to check something.

Looking at the page here:

Which do I need that isn't a contract, ie just to get 30 days worth?

Yes it just a 30 day contract, it will be taken out of your bank account though. It's not a pay as you top up. Also is you go over you data limit because you will be charged.

Thanks. I got it all sorted. As a long time PAYG customer, the whole Pay As You Consume thing was a bit new to me - kind of a cross between PAYG and a contract. So I had to get the whole credit check signing up thing, but I can set my monthly DD to £0, and then just pay for what I use, without being tied in to a minimum monthly amount or time.
