Device Compatibility and Unlocking Requirements
To use an eSIM card intended for Japan, your smartphone must be eSIM-compatible and carrier-unlocked. Most modern iPhones, Samsung Galaxy, Google Pixel, and other flagship devices support eSIM technology. Carrier-locked phones cannot install or activate an eSIM. We strongly recommend checking your device’s compatibility before purchasing.
Dial *#06# to check if your phone is compatible with eSIM. If you see the letters [EID] after dialing, it means your phone is compatible with eSIM! Congratulations!
Detailed, step-by-step instructions for checking your phone’s unlock status on Apple and Android devices are available in the “Device unlock check”.
