This links to a previous thread (http://www.hotukdeals.com/deal/459778/vodafone-sim-10-m-inc-600-x-net-any/) but with a number of advantages.

The tariff is their 'Low Price Reward Plan' and offers:-

Need to call 0808 0 408 408 - they may state that the deal is no longer available but if you say that a friend has been offered it or that you will just get it by going via a cashback site (quidco etc) they will refer it and quickly offer it. Have confirmed that it is still available today and this is confirmed.
