As the title says, I'm looking for the cheapest possible pay as you go vodafone/sim free mobile phone you can find. I don't care if it has a camera, I don't care if it has a colour screen, and I certainly don't care if you need jiggle your ass and shake it like a maracass to turn it on. All I want is a piece of plastic that will allow me to call people. Anything will do. Apart from a mile long string connected to two tin cans.
Reason for this: I plumped for the Vodafone sim-only offer the other day purely for the £90 quidco, and figure I might as well make use of my minutes.
