“Installed it at the gate while boarding. By the time we taxied to the terminal I had 5G and three missed group chat arguments. Used about 8GB in two weeks with maps running daily, zero dropouts.”

Japan eSIM FAQ
Buy a plan, scan the QR code we email you, and your phone gets a digital SIM for Japan. It connects to fast local networks the moment you arrive. Your home SIM stays in place for calls and texts, so nobody has to learn a new number.
Fixed data plans for Japan start at $4.20, and Unlimited Data runs about $4.90 per travel day. Either way it is a flat price you see before paying, which is more than your roaming bill can say.
No. The eSIM installs alongside your physical SIM, so there is nothing to eject, lose, or drop between two seats on the plane. Land, switch on data roaming for the eSIM line, and you are online.
Yes. We connect you to leading local networks, so coverage holds up whether you are posting from Kyoto's pagodas or somewhere your map app pretends does not exist.
Yes, tethering is included on every Japan plan. Share data with your laptop, tablet, or the travel buddy who promised to sort their own internet and is now smiling at you hopefully.
Any time before you fly. You have 180 days to activate after purchase, and validity only starts when the eSIM connects to a network in Japan. Buying early just means one less thing to do at the airport.
