Calling / sending SMS (text messages) overseas

How to make a phone call and send an SMS (text messaging method) from your travel destination

Making a call

Example: Calling from your travel destination to Japan number "03-1234-XXXX"
+ 81 (country code) -3 (area code) -1234XXXX (number of the person you are calling)

Example: Calling from the US to US number "123-456-XXXX"
+ 1 (country code) -123 (area code) -456XXXX (number of the person you are calling)

  • Press and hold "0" or "*" to dial "+".
  • If the person you are calling has a Japanese mobile phone, enter "81" (Japan) as the area code regardless of their travel destination.
  • Please note that calls may connect even when dialed differently from the above. In such cases, you will be charged the applicable call rate based on the destination of the call (within the country of travel, to Japan, or to other countries outside the country of travel).

Sending SMS (text messages) overseas

SMS (text messages) can be used the same way as in Japan.

Important notice for customers not using data communication overseas

If you do not wish to use data communication abroad, please set your data roaming setting to "OFF" before traveling.

For "au Overseas Unlimited," data communication will not start until you tap [Start Usage] via the "au Overseas Unlimited App" (which you can pre-register for in Japan) or through the browser at your destination.

However, for "Overseas Double Rate," if your device's data roaming setting is "ON," data communication will automatically start at your destination. To avoid unexpected charges, we recommend checking and setting this in advance.

[Procedure]

Settings → Mobile Data → Mobile Data Options → Turn OFF Data Roaming
