Martin Lewis has updated his MoneySavingExpert.com website article about making ‘free’ calls from mobiles to 0800, 0808 and 0500 numbers. He talks about 0800Buster.co.uk and QXCall.co.uk, which route calls through a standard UK number. This enables customers to take advantage of their inclusive minutes, which can’t usually be used for calling ‘free’ telephone numbers. [MoneySavingExpert.com]
