7, 15 or 30-day plan for Japan?

How to choose your plan duration

• 7 days: short breaks or stopovers. If your trip is 5–7 days, this is the most cost-effective.
• 15 days: the sweet spot for a standard holiday. Covers most itineraries without paying for unused days.
• 30 days: long trips, remote work or multi-destination routes. More expensive overall, but lower cost per day.

Important

• The countdown starts when you activate the eSIM, not when you buy it. Buy early, activate later.
• If you run out of data before it expires, you'll need to buy a new plan or use Wi-Fi.
• Not all plans allow top-ups — check before buying if this matters to you.
