It say 02 were better.
altho voda are supposed to have better coverage , I think 02 are better because they dont complicate stuff like voda do.
my mates on a voda contract, and he has to pay extra VAT (on 02 its included), he has been stung with.. free TV, internet, ringtones.... for 3 months, then you have to pay for it
I dont think id go on vodafone. they would probably be my last choice tbh.
