Three pay-as-you-go prices to rise by up to 250% for thousands of users

Above-inflation increases for calls, data and text messages will be blow to struggling customers

The mobile phone company Three is pushing through another round of big price increases for its pay-as-you-go customers, with the cost of making a call jumping by an inflation-busting 250%.

The higher call, data and text message costs will be a fresh blow to households already struggling with soaring living costs. Pre-paid mobiles are more commonly used by Britons aged over 65 and those in low income households.
