"Hello mum, I've got a new phone, please save the number": how a WhatsApp scam hit families in north Wales

The "Hi mum" scam feels personal, but it isn't. In early 2022 North Wales Police said it was seeing new victims every day. 12

What happened?
North Wales Police said scammers tried to steal £24,000 from people in north Wales alone. That was in two weeks at the start of January 2022. Victims in Wales lost an average of almost £2,500 each. 1
One mother in Denbighshire got a WhatsApp message that began "Hi mum". It said her daughter's old phone had crashed and asked her to save a new number. The two chatted for a while, and then the "daughter" asked for help paying an invoice. 12
The mother sent £2,100, but the payment bounced. Police think the bank already considered the scammer's account suspicious. 12
A woman on Anglesey saved a new number under her daughter's name and made four transfers totalling £4,800. The bank became suspicious and the last transfer didn't go through. 12
A detective constable with the force said many victims were women with adult children. The detective constable advised calling people back on a different number to check it's really them. 1
Across the UK, the national fraud reporting service received 1,235 reports between 3 February and 21 June 2022. The reports described criminals posing as loved ones on WhatsApp. They involved losses of £1.5 million. 3
How did the scam work?
- A friendly first message from an unknown number, saying they've got a new phone and asking you to save the number.
- Chat to build trust. The scammer makes small talk the way your child might.
- A reason they can't pay. There's no banking app on the "new" phone.
- The request. A bill, invoice or deposit paid to an account that isn't your child's. That makes it a type of APP fraud.
- Some versions ask for your WhatsApp code instead. See one-time passcode scams.
What are the red flags?
- A new number claiming to be family, especially one that opens without using a name.
- Pressure to pay soon, or a short message saying they can't talk.
- Bank details in someone else's name, such as "a friend's account".
- An excuse for not being able to call.
What should you do?
- Don't pay. Call your child on their old, usual number, or ask someone who's with them.
- Ask something only they would know, or ask for a voice note. Bear in mind voices can be faked.
- Forward scam texts to 7726. In WhatsApp, use Block and Report.
- If you've already paid, call your bank on the number on your card as soon as you can. Then report to Report Fraud (opens in a new tab) (Police Scotland 101 in Scotland).
