For a smooth start to your Japanese adventure, we highly recommend scanning your EastESIM QR code before you even leave home. This way, your eSIM profile is ready to go. The moment you land at Narita International Airport (NRT) or Kansai International Airport (KIX), your EastESIM will automatically connect to our partner networks like NTT Docomo, providing instant data. No need to hunt for airport Wi-Fi or worry about connectivity; you're online and ready to navigate Tokyo from touchdown.
