Money-saving expert Martin Lewis says a simple step—typing a “code” on a mobile phone—can help some consumers lower their phone bills. In commentary reported by multiple UK outlets, he describes the process as entering a set of digits that can change how charges are applied, potentially preventing overpayment.
The reports frame the advice as applicable to a large number of people across the UK, with one outlet stating it could help “14 million” users save money. Another describes the action more generally as entering a single code to reduce costs. While the sources emphasize the same core instruction, they differ slightly in the way they quantify potential impact and in the wording used to describe what the code does. Both accounts present Lewis’s guidance as an easy check or adjustment that could reduce mobile spending.
Overall, the outlets agree that Lewis is advising consumers to use a specific in-phone code to improve their mobile deal and avoid higher-than-necessary charges, rather than switching plans directly or making complex changes.
