Vodafone’s Monthly Sim Only plan is packed with more minutes and text for less money than a contract phone. With Vodafone Sim Only you can call any UK mobile or standard landline for just 20p a minute any time you want. Text Messages cost 10p each. You can keep your existing phone and number with Vodafone. When you want to cancel your contract you can do this any time you want, just notice it within 30 days. One example of Vodafone’s Sim Only contract is the 600 minutes and UNLIMITED texts for just £20 a month with a super 30 day contract!
