Unlimited, clearly explained
Made for travel: maps and ride apps the moment you land, WhatsApp and video calls with home, photos and social media on the go. Your home number stays on your own SIM for calls and texts.
Full speed, then continued data
What is an IP exit?
The country where your internet traffic exits to the public internet. It is not a VPN or a fixed IP address, and an app may still place you elsewhere.

Questions about Japan & South Korea
View all FAQs →Does one eSIM really work across all of Japan & South Korea?
Yes. It is a single eSIM with roaming across every one of the 2 countries built in, so crossing a border changes nothing — no second purchase, no swapping profiles, no new QR code. The phone attaches to whichever local network is strongest, the way a local phone does.
When do the days start counting?
When the eSIM first connects to a network in Japan & South Korea — not when you buy it and not when you install it. Install it at home on wifi before you fly and you land already online.
Is a Japan & South Korea plan cheaper than buying each country separately?
For a trip through more than one of them, almost always — one bundle at one price against one eSIM per border. For a single country, that country’s own plan is usually cheaper; every one of them is listed below with its own price, so you can see rather than take our word for it.
