Notes

  • Calls to special numbers including the Answering Service (1417, 09044441417 (remote operation)) are not counted as 24-hour free domestic calls to au mobile phone users.
  • This discount is not applicable to au World Service calling and data communication charges when used outside of Japan, and calling charges through use of a CDMA Prepaid Card.
  • If you sign up for the service, or cancel the contract partway through the month, the flat rate is calculated on a prorated basis.
  • This discount cannot be combined with "Call Designation Flat Rate".
  • You can choose the timing of the change from two options, "this month" and "next month". If you choose "this month", the change will be applied from the day of the application.
