Japan Wireless eSIM

Should I use unlimited plan or data plan?

If you plan to consume a large number of internet in a short amount of time. e.g. Streaming, Video calling etc. We recommend buying a 30GB plan or a 50GB plan instead.

What should I do if I deleted or lost the QR code for my eSIM?

Make sure to download the PDF and QR code that will appear the moment you finish buying your Japan Wireless eSIM on our website. You can also check your email if you forgot to do so. If you cant find your QR code please message us at: [email protected] Our 7 days a week customer service center will get back to you as soon as possible.

What should I do if my QR code is not working?

Firstly, it's important to understand that eSIM QR codes can only be activated once. Any subsequent scans will not be successful. To check the activation status of your eSIM, please go to the "My eSIM" section and look under the "Purchased" category on our website. If it's not activated, you can attempt a manual setup. . • iOS(Iphone, Ipad): Activation Guide • Android(Samsung Galaxy, Google Pixel, Motorola etc.): Activation Guide If it’s still not working, don’t hesitate to contact us at: [email protected]

When do you reset my data plan?
