Martin Lewis has urged everyone with a mobile phone to dial a five-digit code and screengrab the result
It’s so rare that you’ll know someone who doesn’t own a mobile phone these days. These little squares have become a vital component of daily life, which is why it can be all the more annoying when they get stolen.
The devices that feel like that our whole lives are in, can be snatched in the blink of an eye and be a major inconvenience. And with technological advancements, it’s easier for thieves to target bank accounts.
But there are ways owner can protect their devices, as well as important information and one way to do this is by using a simple code. The useful tip has been backed by finance guru Martin Lewis, who previously explained why every phone owner should dial it as soon as, reports the Express.
The Money Saving Expert founder shared this advice on his ITV show in 2025, following reports at the time that phone thefts have surged by 40 percent, as criminals increasingly target individuals’ financial information via their mobile devices.
He stressed the importance of immediate action to secure handsets against unauthorised access in the event of theft, thereby reducing the risk of thieves draining bank accounts through stolen phones.
Martin advised viewers to modify key settings on iPhone, Samsung and Google phones for enhanced protection, including text message settings.
Speaking on his March 11 episode of Martin Lewis Money Show Live last year, he said: “Mobile security tips – thefts are up 40 percent in London but they’re going up right across the country too.
“Now the crucial thing, they’re not just trying to nick your phone, some of them are trying to access your financial data from your phone.”
“You have to protect yourselves on this, folks.”
Martin recommended the use of remote tracking apps such as Apple’s Find My, Samsung’s SmartThings or Google Android’s Find My Device to locate stolen phones and suspend payments.
He further suggested enabling biometric features like fingerprint ID sign-in on both mobile devices and banking apps, and emailing oneself a screenshot after dialling the provided code.
Martin advised: “Now, this one sounds a bit peculiar. Dial *#06# to get your IMEI image then take a screenshot and save it.
“That’s what you’ll need to provide to the police if your phone is stolen. Screenshot it and assuming you can access your email not just on your phone, I would just email it to yourself so you’ve got a copy somewhere.”
Lastly, Martin emphasised that ‘possibly the most crucial’ tip is to ensure two-factor authentication does not appear on your lock screen.
He explained: “Many people have that appear on their lock screen so when your phone’s locked, the code still appears. You don’t want that. It means if someone gets your phone they can get the code. So what you need to do to prevent that is turn off your ‘preview notifications’. It will still tell you you’ve had a message but it won’t display your code on your message. Everyone please do that one. It’s a nightmare if you’ve not done it.”
The Martin Lewis Money Show Live episode from March 11, 2025, is still available for viewing via ITVX.
