Wangiri Missed Calls: Why One Ring From an Unknown Number Is a Trap

This tutorial video explains the "one ring" or Wangiri scam, where a number rings your phone once and hangs up so that you will call back out of curiosity. You will see what a typical missed call from an unfamiliar international or unusual-looking number looks like, and why calling back can lead to a premium-rate line or a long recorded message designed to keep you connected. The video shows how to check a number safely by searching it online or asking a trusted adult instead of calling it. It then walks through blocking the number in your phone's call settings, reporting it as spam, and checking your call history and credit if you already rang back. You finish with a simple rule to follow: if you don't know who called, don't call back.
