Frequently asked questions

Will my phone work with a Japan eSIM?

Any eSIM-compatible phone bought in the last few years (iPhone XS or newer, Pixel 3 or newer, recent Samsung Galaxy, etc.) works with our Japan eSIMs. Use our compatibility checker if you are unsure.

When does the Japan eSIM start counting?

Validity starts the moment the eSIM connects to a network in Japan, not when you buy it. You can install it before your trip without losing days.

Do I keep my regular number while using the Japan eSIM?

Yes. Your physical SIM stays active for calls and SMS on your normal number. The Japan eSIM only handles mobile data, so WhatsApp, maps, and apps keep working.

Can I tether or use a hotspot in Japan?

Yes, all our Japan plans allow tethering and personal hotspot, so you can share data with a laptop or another device.

What happens if I run out of data in Japan?

You can buy a new plan for Japan at any time and install it on top of the previous one. No need to wait or visit a shop.

Is the Japan eSIM refundable?

If you have not installed or activated the eSIM yet, contact our support and we will issue a refund. Once the QR has been scanned and the eSIM activated, it cannot be refunded.
