SMS Scam: What to Do? The Right Reflexes

Received a strange text asking you to click a link or call a number? Don't panic. Here's how to spot a scam, what to do in the first few minutes, and how to protect yourself going forward.

🚨 How to spot a fraudulent text message

Scammers are getting more sophisticated, but their messages almost always share the same telltale signs.

⚠️ The 7 warning signs
  • A strange link — shortened URL or odd domain name (e.g. royalmail-delivery.xyz)
  • Artificial urgency — "Your parcel expires in 24h", "Immediate action required"
  • A request for money — customs fees, unpaid delivery charges, a fine to pay
  • Unknown sender — foreign number (+44, +1…) or hidden number
  • Spelling mistakes — poor grammar is often a giveaway
  • Request for personal info — card number, password, verification code
  • Unexpected prize — "You've won an iPhone", "Your refund is ready"

Real examples of SMS scams

✅ What to do if you receive a suspicious text

  • Do not click the link — even just to "check" if it's real
  • Do not call back — premium rate numbers can be costly
  • Report it — forward the text to 7726 (free, works on all UK networks)
  • Block the sender — in your phone settings
  • Never share a one-time passcode you received by text
  • Don't reply "STOP" — it confirms your number is active

😰 What if you already clicked?

⚡ You clicked but didn't enter anything
  • Close the browser immediately
  • Run an antivirus scan on your phone
  • Monitor your accounts for a few days
  • You're probably in the clear
🚨 You entered your bank details
  • Call your bank immediately on the number on the back of your card
  • Ask them to block your card
  • Change your online banking password
  • Report it to Action Fraud (actionfraud.police.uk)
