Having trouble with your eSIM?
No internet when you arrive? Most of the time the line was switched on before departure and the phone did not restart its network search on landing: the three steps below unblock it. Also check the two roaming settings further down, which are essential on our data plans.

No internet after landing in Japan?
The 5 fixes, in order: line and data, roaming, line off for 30 seconds, restart, reinstall.
Tip: start the video, then switch it to picture-in-picture: it stays on screen while you change your settings.

Installation interrupted? Don't worry.
If you got cut off during the eSIM installation or setup, it's fine: in most cases the eSIM is already installed on your phone. You just need to enable the options directly in Settings — the two settings below.
The three steps that unblock your line
1Switch the line off, then on again. In Settings → Cellular, turn off your eSIM's line (the name your iPhone gave it, often “Travel” or “Business”), wait 30 seconds, turn it back on — and check while you are there that the data line selected is indeed your eSIM.
2Restart your phone. If nothing changes, a restart makes it search for the Japanese network again.
3Reinstall your eSIM from your installation page: it starts fresh and almost always reconnects straight away. You can reinstall it up to 10 times, but only on this same phone: it never moves to another one, not even a new one. And if this phone is lost with the eSIM on it, it cannot be reissued.
Roaming on your primary SIM
✕ OFF
Keep roaming off on your primary SIM: you'll avoid the high fees your home carrier charges abroad.
