Wangiri fraud.

Wangiri fraud (a Japanese term meaning “one and cut”) is when a fraudster calls a number and hangs up after one or two rings, which encourages you to call them back. These numbers are often based internationally, so you could receive a charge for calling them back. We're taking the necessary measures to protect and maintain security on our network. If you have received an unexpected call from an unknown international number, do the following:

  • Don't answer the phone
  • Don't call the number back
  • Never share any personal information.

If you suspect you've received one of these calls, please Contact Us. When you do, please ensure you include the full number of the call received, country code and date/time of the call received.
