This is for Sim only deals where you use your existing phone. Had 4 phones with Vodafone and all contracts were due to upgrade, was costing me £140 month. Now switched to Lebara which uses the Vodafone network(only one that works at our house). The plan we're on is 15GB data with unlimited calls and texts at £10 month (£5 for 1st 3 months) but you pay for picture messages-or use whatsapp for free. Its a 1 month rolling contract so you can jump ship at anytime, I swapped last month to make sure it worked -you need to text PAC to 65075 to keep your own number- and just switched the rest of the family over. If you use this link - http://aklam.io/yEkIEq - you get first 3 months at half price and i get a tenner! I'll have saved enough to pay the increase in our electricity bill....
