Precautions

Even if you encounter problems when setting up the communication line

Please do not delete the registered QR code.

Once you delete a registered QR code, you will not be able to use the same QR code.

In addition, when registering the QR code and switching mobile communications, we recommend connecting to a different Wi-Fi network for registration instead of using the main line.

How can I tell if my phone supports eSIM?

Your phone must meet two conditions:

Scenario 1:

• If the query results are as follows, it means your phone is not locked, and you can continue to the next step.
• Android: Set up mobile network connection with SIM card [Information and settings: Auto-select carrier (select multiple available networks)]
• Apple: General settings regarding shipping lock (no SIM card restriction)

Scenario 2:

• Access your phone's dial pad and dial *#06#. If an EID message appears, your phone supports eSIM. If no EID message appears, your phone does not support eSIM.
• In this case, please do not place an order to avoid affecting your travel plans due to your phone's lack of eSIM support.

This line can be used throughout Japan, but there are areas where the signal is difficult to reach, and in some areas outside the supported area, it cannot be used at all.

Some places are inaccessible to radio waves, such as inside buildings or underground areas with many shielding objects like concrete, high-altitude areas, mountainous areas, or forested areas.

Additionally, some areas within the airport may experience difficulties using the service due to radio interference. In such cases, please try moving to another location to see if you can connect.
