"Hi Mum, it's me on a new number"

Escudo guide · Updated July 2026

Every other scam in these guides hangs on a dodgy link or a fake payment page. This one has neither. There is nothing for a filter to catch in the wording, no giveaway domain, no countdown timer. It is built entirely out of love and worry, which is why it is the hardest of the lot to defend against and why it deserves a guide shaped around the feeling, not the technology.

The slow open, then the ask

It rarely starts with money. It starts warm. A text or a WhatsApp from a number you do not recognise: "Hi Mum, dropped my phone down the loo, this is my new number, save it please x". No request, just a hello and a reason the number changed. You save it. You feel a small relief that your child sorted their phone out.

Then, an hour or a day later, the real message. A bill that has to clear today. A deposit they will lose. A new phone they cannot get into their banking on, so could you just pay this one thing and they will send it straight back tomorrow. Because you already accepted the new number, the part of you that would have paused is quiet. That gap between the friendly hello and the urgent ask is not clumsiness. It is the design.

Why it slips past careful people

People who would never tap a parcel link fall for this one, and it is worth being honest about why. It does not target your judgement, it targets the thing underneath your judgement.

• It runs on love, not logic. The second you believe your child is stuck, the careful, sceptical part of your mind steps back to let you help. That is a good instinct being turned against you.
• The number is explained before you can question it. By the time money comes up, the strange number already has a story, so it no longer feels strange.
• Pressure wears a shy face. "Please don't tell Dad", "I'm really embarrassed", "it just has to be today". A genuine emergency almost never needs you to keep it secret from the rest of the family. Secrecy is a scammer keeping you away from the one person who would say "ring her first".
• A familiar voice is no longer proof. Some of these have moved to phone calls that use a few seconds of a cloned voice. If it sounds right on the phone, that still is not confirmation. The check below is.

The check that ends it in one call

Whatever the message says, the answer is always the same small act. Put the text down and make a separate call.

1. Send no money and read out no codes while you are unsure, however urgent it sounds. Urgency is the pressure, not the truth.
2. Ring the old number. The one already saved in your phone, not the new one that texted. If your child picks up and knows nothing about it, you have your answer in ten seconds.
3. Ask something only they know and that is not on Facebook. What you cooked last Sunday, the name of the cat you had when they were small. A scammer stalls, dodges or gets cross.
4. Say the pressure out loud. "I'm going to call you before I send anything" is a full and reasonable sentence. Your real child will understand completely. A scammer pushes harder, and that extra push is the confession.

The Escudo app does not tell you a message is fake, because it cannot know that and neither can anyone else. What holds here is simpler than any app. Verify on a separate call and never pay under pressure, and if someone is frightening you into sending money, ring the authorities.

If money has already gone

• Ring your bank now on the number on the back of your card. A transfer can sometimes be stopped or clawed back if you call within minutes, so do not wait.
• Keep the messages and the number. Do not delete them in a fluster, they are evidence.
• Report to Action Fraud at actionfraud.police.uk or 0300 123 2040. In Scotland, report to Police Scotland on 101. Call 999 only if you believe someone is in genuine, immediate danger.
• Under UK rules banks must reimburse most victims of authorised push payment fraud, which is what this is. Ask your bank about a reimbursement claim and do not let shame stop you.

Being caught by this is not a mark of being gullible. It is a mark of loving someone, which is exactly what the scammer was banking on. If it turned out there was a link involved rather than a transfer, see you already tapped a scam link.

The plan that protects your mum before it happens

This is the scam that wounds the most, because it wears the face of family, so it is the one most worth heading off in advance. Two agreements do nearly all the work. First, pick a family word today, out loud at the dinner table: an ordinary phrase anyone can ask for on an odd call before a penny is discussed. Second, agree one rule between you all, that no money ever moves on a text from a new number until someone has rung the old number first. Boring, and it works every time.

The very same wound is pressed the same way abroad, running in the States as the "Hi Mom" text and in Portugal as "olá mãe, mudei de número", one script wearing many languages. The Escudo app helps with the first door, the flood of scam texts that pile into the unknown senders folder, by filtering known scam patterns and setting them aside before they are read. It cannot judge whether a particular message is truly your child, and it never claims to. Nothing is deleted, only set aside, and your messages never leave the phone. The family word and the phone call are still what keep everyone safe. To understand who is on the other end of these, read how SMS scam gangs actually operate.
