Setting up your eSIM for Tokyo is straightforward. After purchasing online, you'll receive a QR code. Scan this code using your smartphone's settings (usually under 'Cellular' or 'Mobile Data') before you leave home. Do not activate the data plan until you land in Tokyo to maximize your validity period. This ensures you're connected the moment you arrive at Narita or Haneda.
