  2. Smartphone applications and software may automatically communicate via the Internet, and the resulting packet transmission will be charged accordingly.
  3. Incoming calls received abroad are charged to the customer as well as the caller.
  4. Calls are timed and charged from the moment when SEND is pressed in some countries/regions. In such countries/regions, therefore, calling charges are charged even when calls fail to be connected.
  5. All transmissions, including those requiring no packet transmission charges in Japan, are subject to packet transmission charges abroad.

  6. World Flat-rate Data or Overseas Double-Teigaku is applied for the use of packet transmission through specified overseas carriers. For details of specified overseas carriers and conditions, check the World Flat-rate Data or Overseas Double-Teigaku page.

    World Flat-rate Data

    Overseas Double-Teigaku

    If you are subscribed to a domestic packet communication flat-rate service, packet communication charges eligible for World Flat-rate Data or Overseas Double-Teigaku are not eligible for free call allowances included in each rate plan. However, free call allowances included in each rate plan are applied to packet communication charges ineligible for World Flat-rate Data or Overseas Double-Teigaku. Even if you are subscribed to Family Discount or Business Discount and the Sharing Course is selected, unused free call allowances of other family members or other members in the group are not applied.

  7. The determination of International Roaming Service charges is dependent upon overseas telecom carriers and may become delayed, so calling charges may not be reflected in the call detail record of the billed charges or telecommunications record until the subsequent month or later. (The contracting person and user should understand this fully before transferring an au mobile phone or changing user information after use of this service.)
  8. Check "Using overseas (au World Service) -> Before leaving Japan" for the condition of overseas communication networks.
    Before leaving Japan (in japanese only)
  9. To reduce the risk that the au IC-Card of the customer may be used by another person if stolen or lost, it is strongly recommended that the customer set a "PIN1 code" for the card.
    Please see the "user manual" of the au mobile phone for the PIN1 code setting method.
