How to Call Japan from the U.S.

It’s easy to call Japan from the United States.

You can use either your Ooma Telo-connected home phone or the Ooma Mobile app.

  • First dial 011 to exit the U.S. telephone system.
  • Now dial 81, which is the country code for Japan.
  • Next, dial the local number, which is either 9 or 10 digits.

Calls made with the Ooma Mobile app do not use any cellular minutes or incur international charges on your wireless bill. Instead, these calls are routed over your data connection and may not count against the data allotment with your cellular phone provider. To minimize data usage, connect to a W-Fi hotspot.
