How Does an eSIM Japan Unlimited Data Work?
Watch videos, engage in live video calls, browse the internet and manage all your daily online work with an unlimited data eSIM for Japan. Physical SIM card installation is not required for an eSIM as it is a digital SIM card. Just having a smartphone with eSIM support is enough to activate the eSIM on your phone. The eSIM Japan for unlimited data works in the below manner:
- 1
Purchase an eSIM Plan: The Japan unlimited data eSIM can be purchased from an eSIM providing app or site.
- 2
QR Scan: Once you purchase the eSIM, a QR code will be sent on your registered email address. Scan this code after activating the WiFi of your phone to activate the eSIM profile.
- 3
Activate eSIM: The eSIM plan does not start immediately after profile activation. It starts only when you arrive in Japan and the eSIM connects with a local network.
- 4
Use Unlimited Data: Once these steps are completed, the eSIM for Japan unlimited data will start working. You can also keep your home SIM active for receiving calls, SMS. and OTP codes.
