If you're visiting more than one country on your trip, this is an important distinction to understand before you purchase.
If you buy a regional plan (e.g. "Europe" or "Asia-Pacific"), you can use the same eSIM across all countries included in that region. Your data allowance is shared across all covered countries — no need to swap eSIMs at each border.
If you buy a country-specific plan (e.g. "Japan 5GB"), it will only work in that country. If you travel to another country, you'll need a separate eSIM for that destination.
If you're visiting several countries in one trip, a regional plan is usually the best option. It saves you the hassle of buying and managing multiple eSIMs, and you get one shared data pool across all your stops.
