Product FAQ

How will I get the QR code to install this eSIM?

Once purchased, you will receive an email containing the QR code. You must use it within 30 days, or else the plan will expire.

Can I scan and install the data plan and use it later?

You can install the plan by scanning the QR code before your departure and it will be connected once you arrive in Japan.

Can I install the plan without an active internet connection?

No. You must be connected to WiFi or an internet connection to install this plan.

Can I transfer my eSIM from one phone to another phone?

Once the eSIM code is scanned on one phone, it cannot be transferred to another phone because the plan tied to the code is specific to the original phone it was scanned on.

After installing the eSIM, can I delete it and reinstall?

No, once you remove or delete the eSIM plan from your device, it cannot be reinstalled and we will not be able to reissue new eSIM to you. Refund is not applicable for this said case.

I will arrive in Japan at 10pm local time, may I know how is the days validity counted?

Once you arrive and the eSIM is connected at 10pm (Japan local time), after 2 hours at 12am it will be considered as 1 day usage. The daily calculation is based on 12am-12am block.

My existing local phone number is an eSIM line. Can I still use this eSIM together with my local eSIM phone number?

Phones have the capability to install multiple eSIM profiles, but their active use is limited to just one (1) or a maximum of two (2) eSIMs concurrently. For instance, Samsung phones that support eSIM functionality can utilize just one (1) eSIM at a time, in addition to one (1) physical SIM card. Therefore, you have the option to temporarily deactivate your local phone number eSIM and switch to this eSIM for your travel needs, or you can opt for a physical travel SIM card and operate both lines simultaneously.
