Frequently Asked Questions

Questions about this plan

Activate the eSIM just before you need it in Japan (ideally upon arrival, or whenever you want the timer to start). Once the eSIM is activated and used, the 3-day period counts down continuously. To avoid wasting time, avoid activating it the day before if you don't need internet access before departure.

You don't have a data quota to monitor: GPS/maps, messaging, social networks, audio/video calls, and app updates remain usable without counting gigabytes. Depending on local network policies, the speed may be adjusted in case of very heavy usage or congestion, but you remain connected throughout the entire period.

Activate tethering only for the necessary time, connect your computer, and then turn off the hotspot as soon as you're finished. To conserve battery, keep your phone screen off, turn off Wi-Fi/Bluetooth when not needed, and choose a location with good coverage (the phone will heat up less).
