Frequently Asked Questions

Questions about this plan

Activate it just before leaving (or as soon as you land) and start the installation via Wi-Fi. The validity period begins when the eSIM connects to the mobile network in Japan: avoid activating it the day before if you want to make the most of your 24 hours there.

Install the eSIM over Wi-Fi, then configure your key apps before heading out: Google Maps (offline maps), messaging apps, QR codes/booking information. Next, use the eSIM as your data line and keep your power-saving mode enabled: you stay connected everywhere without needing a device to charge or carry.

You don't have a daily data limit to monitor: you can browse the internet, use GPS, messaging, social media, and watch videos. Depending on the local network and network traffic, speeds may vary, and traffic management may be implemented after periods of high usage, but you will remain connected for the entire validity period.
