A new scheme called the Vodafone Bonus Bank will reward prepay customers every time they top up their phone. For example, for every £10 someone tops up by, Vodafone will place an extra £1 into a savings account. However, customers will only be able to spend this 'bonus' after three months and as long as they've saved a minimum of £5.
Customers will then be able to decide whether to spend their savings on topping up their phone, or putting it towards a new handset.
Any Vodafone prepay customer can sign up to the scheme by simply texting the word "BonusBank" to 2345, or alternatively by calling the same number or visiting www.vodafone.co.uk/bonusbank.
