How do I check if my phone supports Japanese eSIMs?
Dial *#06# on your dialer to verify your device has an EID number. Make sure your carrier has fully unlocked your handset before traveling to Japan.
When should I install my Japan eSIM QR profile?
Scan and install the profile 1 to 2 days before departure via Wi-Fi. Turn the data roaming line on only after touching down at Haneda, Narita, or Kansai airport.
