About Course
Your phone rings once and stops. The missed call is from a long number you do not recognise. It is natural to want to call back – but that is exactly what scammers hope you will do. This course explains “missed call” (Wangiri) scams, how to recognise an overseas number, and how to block and report these calls.
This course gives general information about phone scams in the UK. Country codes are examples only; scammers change the numbers they use.
