Money-saving expert Martin Lewis has called on mobile phone users to stop overpaying for their contracts, urging them to switch to cheaper SIM-only deals that could slash their bills to as little as £6 per month. In a TikTok video featuring The Martin Lewis Money Show segment, he captioned it bluntly: “Stop burning cash.”

During the program, Lewis highlighted a shocking trend: while prices for most household bills are soaring, mobile phone costs have dropped. Yet, many people are still paying over £30 a month unnecessarily. He said that if a mobile bill exceeds £10 per month, it’s time to reconsider.

“Are you paying over £10 a month? If so, why?” he asked viewers, referencing a Twitter poll he had posted in which a surprising number of respondents admitted to paying upwards of £30.

While some may justify higher costs due to handset repayments or frequent roaming, Lewis pointed out that most people simply overpay out of habit.

Lewis explained that the key to saving money is switching to a cheaper SIM-only plan. He outlined how easy it is to move networks while keeping the same number.

Simply text PAC to 65075, and the current provider will send a PAC code, which can be given to the new provider to switch seamlessly.

Most SIM-only deals now come with unlimited minutes and texts, meaning the main factor in pricing is data usage. While heavy streamers may need more, the average UK user only consumes 4GB of data per month, and deals for that amount are available at incredibly low prices.

This means customers can keep their network’s signal strength while significantly reducing costs.

In addition to switching to a lower-cost SIM, Lewis recommended looking into airtime rewards apps, which can provide cashback on mobile bills.

He also mentioned the Nationwide FlexPlus bank account, which, for £13 per month, includes mobile phone insurance for the entire family, as well as travel insurance and European breakdown cover, potentially saving hundreds of pounds a year.

With SIM-only deals now available for just £6 per month, there’s no reason to continue “burning cash” on overpriced contracts.

By switching to a cheaper provider, consumers could free up hundreds of pounds per year, money that could help offset the rising price of other household bills.
