One Ring Scam – International Number Trap
Medium RiskOverview
This scam relies on curiosity - victims receive a missed call from an unfamiliar or international number, and if they call back, they are charged premium rates or redirected to fake services designed to keep them on the line as long as possible.
Typical Targets
- •Anyone with a mobile phone
- •People expecting important calls
- •Those who don't recognise international dialling codes
- •Curious individuals who call back unknown numbers
Why This Scam Works
- •Curiosity about who called
- •Fear of missing something important
- •International codes aren't well known
- •One ring creates urgency
- •Premium rate charges aren't immediately visible
Real Example
“A Dublin man noticed a missed call from a number starting with +882 (satellite phone code). Curious, he called back. An automated message played in a foreign language. He stayed on for 3 minutes trying to understand before hanging up. His phone bill showed €47 in charges for that single call.”
