Scammers rely on urgency and trust. They create time pressure so you act before verifying, and they impersonate a sender you\u2019d normally trust without a second thought.<\/p>\n\n\n\n
\n- A missed call from an unfamiliar international number, especially unusual country codes<\/li>\n\n\n\n
- The call lasted only a second or two<\/li>\n\n\n\n
- You don\u2019t recognise the area\/country code at all<\/li>\n<\/ul>\n\n\n\n<\/div>\n\n\n\n\n\n
How to protect yourself against one-ring fraud<\/h2>\n\n\n\n\n\n\n- Don\u2019t call back numbers you don\u2019t recognise, especially international ones that only rang once<\/li>\n\n\n\n
- Look up unfamiliar country\/area codes before calling back<\/li>\n\n\n\n
- Ask your mobile operator whether they offer premium-rate call blocking<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div><\/div>\n<\/div>\n\n\n\n<\/div>\n\n\n\n\n\n\n\n
If you think you’ve been targeted<\/h2>\n\n\n\n
\u2022 Check your next bill for unexpected premium-rate charges.
\u2022 Contact your mobile operator to dispute the charge and block the number.<\/strong>
\u2022 Report the number to your operator and national telecoms regulator.
