The eSIM is a Digital SIM, embedded into your smartphone which allows you to activate a data plan anywhere in Japan (such as Tokyo, Chiba, Osaka, Kyoto)
eSIMs are available for a wide range of devices including smartphones (such as Iphone 11, iphone 12, iphone 13, iphone 14 as well as the pro and max versions, Samsung Galaxy S23 Ultra and the Samsung Galaxy A14), and tablets. Please check here for the full list of compatible devices before purchasing.
It depends on the device. Some devices support dual SIM functionality, allowing for the use of both an eSIM and a physical SIM card at the same time. Others may only support one SIM card at a time.
Unfortunately no. Japan Wireless eSIM limits the use to one device at a time.
Our eSIMs exclusively offer data services without a phone number for text messaging or calling. However, you’ll still be able to make calls or send messages via communication applications (Messenger, Whatsapp, LINE, etc).
We accept the following payment methods for our cheap eSIM service:
・Credit and debit cards (Visa / Mastercard / American Express / JCB / Discover & Diners)
As eSIMs are digital SIM cards, there are no physical assets involved. Upon ordering, an email will be sent to you containing a QR code for eSIM activation.
Feel free to place an order for our eSIM before you leave or after you reach your destination. Just keep in mind that the validity period commences when you scan the QR code and install the eSIM onto your device. If you are visiting Tokyo, both Haneda & Narita airport provide free internet access which will allow you to install the eSIM onto your device.
The eSIM must be activated within 180 days for the BASIC plan and 30 days for the HIGHSPEED plan from the purchase date; otherwise, it will expire and become unusable.
Please activate your eSIM in Japan since the validity period starts once your eSIM is activated regardless of your location. Airports such as Haneda, Narita, Itami and Kansai International provides free wifi access so you’ll be able to download your eSIM there.
The validity period starts once your eSIM is activated regardless of your location. 1 day is calculated as 24 hours. For example, if activation time is April 17th 22:00, the expiration time will be April 18th 22:00.
Your usage of the data plan will reset the next day at the same time in which you activated your eSIM.
If your device is equipped with this functionality, you can certainly share your data with other devices. E.G. If you activate your eSIM on your Iphone 14 pro max, you can utilize your hotspot to share data to your Samsung Galaxy A14.
For IOS devices: Go to [Settings] > [Cellular] > [Personal Hotspot or Settings] > [Personal Hotspot] and make sure it’s turned on. Then verify the WiFi name & password. Make sure to stay on this screen so that you can share your eSIM data WiFi to other devices.
For Android Devices: Go to [Settings] > [Network & Internet] > [Hotspot & Tethering] > Toggle on [WiFi Hotspot]. Once turned on you should be able to share your eSIM data with other devices!
Our eSIMs can go up to 40Mbps (download).
No. Your eSIM can still be activated outside of Japan but it will only be able to access the internet in Japan. Therefore it is recommended to download the eSIM by utilizing the free internet service in airports such as Haneda, Narita, Kansai International or Itami if visiting Tokyo or Osaka.
I already ordered and I have questions
There are two methods of eSIM activation: 1) QR Code eSIM Setup 2) Manual eSIM Setup
Please refer to the eSIM setup guide. - iOS (Iphone, Ipad) eSIM Setup Guide - Android(Samsung Galaxy, Google Pixel, Motorola etc.) eSIM Setup Guide
When it comes to Daily eSIM Plans, your eSIM internet connection will remain active, but it will operate at a decreased speed. For our eSIM Data Plans, once you exceed your data limit, the internet connection will be suspended.
Unfortunately, topping up your eSIM plan is still not available at the moment. If you require additional data, the only option is to purchase more data. For temporary usage, we recommend selecting daily plans.
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. .
While coverage, congestion, and the local carrier's prioritization can impact connection speed, if you're facing slow network speed, please follow these steps:
- Change your APN (Access Point Name) settings.
- Temporarily set your device to 4G.
If the issue persists, try the following:
- Set your device to 4G or LTE.
- Enable and disable airplane mode.
You cannot cancel your order once you have purchased a data plan, even if you have not activated your eSIM yet.
Regrettably, we cannot issue refunds for eSIMs. Therefore, it is important to verify in advance that your device, whether an iphone or a Samsung, is unlocked, designed for data-only eSIMs, and intended for use solely in Japan before making a purchase. *Please note that some devices may not be compatible based on the purchase location.
Make sure your data roaming is turned on. If you have it turned off, your eSIM will not work. Please refer to our activation guide for a step by step process:
