After your purchase, a QR code will be emailed to you. Please activate it within 30 days of arrival at your destination, or the plan will no longer be valid.

Please scan the QR code before your departure to activate the plan. Remember that the validity period will begin after the QR code is scanned.

No. To install this plan, please ensure you are connected to WiFi or the internet.

After scanning the Japan eSIM code on a phone, it cannot be moved to another device, as the plan associated with the code is exclusively linked to the original phone where it was activated.

Phones can install multiple eSIM profiles, but you can actively use only one (1) or a maximum of two (2) eSIMs simultaneously.

For example, your phone that supports eSIM functionality can use only one (1) eSIM at a time, along with one (1) physical SIM card. As a valued customer, you can temporarily deactivate your local phone number eSIM and switch to this eSIM for your travel needs. Alternatively, you may prefer to use a physical travel SIM card, allowing you to operate both lines at the same time.

  2. Select Data Usage.
  3. Please ensure the mobile data is activated, then click on Billing Cycle and Data Warning.
  4. Select the starting point for the billing cycle and adjust the date according to your arrival in the destination country.

  6. Allow the configuration of traffic limits and define those limits using numerical values. This option disables the transmission of data once you hit the specified limit.

For Google Pixel devices:

  1. Launch the Settings application, then select Network and Internet.
  2. Select SIM.
  3. Ensure that mobile data is activated, then select the data traffic warning and upper limit options.
  4. Select the mobile data usage period and adjust the date to match your arrival in your chosen country.

  6. Activate the option for setting a traffic upper limit and define the limit with a specific number. This option disables the transmission of data once you hit the specified limit.
