Install the eSIM before Narita, or buy at the airport?
Affiliate links. Airalo is tracked. Holafly and Ubigi are official, untracked. Recheck prices at checkout.
Buy and install at home. Activate data after you land. The airport is for phones that refused the eSIM.
Holafly’s Japan page: install before or during the trip; the plan starts when you connect in Japan. You still need internet to add the plan. Home Wi-Fi is that internet.
This page does not invent an airport booth yen price.
