Freebieworld

4 Free Sim Cards does exactly what it says on the tin (or website name) - they give you 4 free sim cards. They’re for the Vodafone network and all you have to do is register your address with the site (which we don’t believe is related to Vodafone, but a mobile phone company?) and they’ll send you your free sim cards. According to the blurb we’re sent, “none of the information will be sold to a third party and you’ll receive your sim card within 3-4 working days”.

As well as the free cards, they’re offering a prize £20 worth of calling credit - just answer a few additional survey type questions to enter the competition.
