Experts are warning everyone with a mobile phone that they risk overpaying by as much as £352 a year if they aren’t careful this month. Hundreds of thousands of mobile phone contracts are due to expire this month, according to Uswitch. Mobile customers who signed up for a 12-month deal during last year’s Black Friday sales or a 24-month deal in November 2022 will soon see their contracts expire, meaning they will be out-of-contract and at risk of overpaying if they don’t take action.

The biggest savings can be made for customers who will be out-of-contract on a pay-monthly handset deal, which could see them continuing to pay for a phone they have already bought during their contract. Customers on an expired mobile handset deal can save £352 a year on average if they hang onto their current handset and switch to a new SIM Only deal. Uswitch, the comparison and switching service, encourages all mobile customers to text INFO to 85075 to check if their contract is due to expire and see if they can save by switching to a cheaper deal this Black Friday.
