Japan Unlimited eSIM Offer

Choose Unlimited when you prefer a daily high-speed allowance with reduced-speed data afterward. Choose the 30-day fixed-data plan when you want one total allowance to use across your trip. Compare the current totals in the selector, and adjust the Unlimited days to your actual travel dates.

A Japan package uses its supported local networks as you travel between those cities. You do not need to change the eSIM for each stop. Coverage and speed still vary by network, building and route, so keep the next hotel address and connection saved offline.

Use data for route searches, train changes and station directions wherever the supported network has signal. Tunnels and remote sections can interrupt service. Save any ticket you must show, along with the next connection and your accommodation address, before boarding.

Read the selected package's start rule before installing. Some packages start at installation and others at the first supported network connection. Use a reliable internet connection for setup, save the instructions, and select the travel eSIM for mobile data when the instructions tell you to.

Treat the package as data-only unless its details explicitly include a number, calls or SMS. A data connection does not supply a Japanese number for reservations or verification. You can keep your usual SIM available for messages, subject to your home carrier's roaming charges.
