I bought mine in the north but I imagine it would be the same anywhere. I bought a cheap PAYG phone for about £12 in Tesco. I feed it using PAYG coupons, also bought in Tesco. Both bought with cash (and without loyalty card) so totally untraceable and anonymous.
I got mine (SIM & Phone) in a Vodafone shop too. I wasn't asked for an ID, address or anything at all when I bought it.
Needless to say too, I haven't registered it online either, and I top it up using cash only aswell.
