Japan eSIM for Travellers: Tokyo, Kyoto and Osaka
Travel eSIM data in 210+ countries
Visiting Tokyo, Kyoto, Osaka or Hokkaido? A travel eSIM gives you mobile data from the moment you land, for train routes, maps and translation apps – without renting a pocket Wi-Fi.
Why use an eSIM here
- Data from the moment you land at Narita, Haneda or Kansai.
- No pocket Wi-Fi to collect, carry and return.
- Keep your home number for calls and bank texts.
- Ideal for rail trips across the country.
How to get connected in 3 steps
- Choose your plan on our eSIM page and enter code CONNECT at checkout.
- Install the eSIM before you travel by scanning the QR code you receive by email (most recent iPhones, Samsung Galaxy and Google Pixel phones support eSIM).
- Turn on the eSIM line and data roaming for it when you land – your normal SIM can stay in the phone for calls and texts.
Travel tips
- Map apps show train routes, platforms and times – keep data for travel days.
- Translation apps help with menus and signs.
- Install the eSIM at home on Wi-Fi before you fly.
Questions travellers ask
Is an eSIM better than a pocket Wi-Fi in Japan?
For most travellers, yes: there is nothing to collect or return, nothing to charge, and each person has their own data.
When should I install it?
Install it a day or two before you fly, while you are on Wi-Fi at home. Then turn the eSIM line on when you land.
Does my phone support eSIM?
Most recent iPhones (XS and newer), Samsung Galaxy S and Z models and Google Pixel phones support eSIM. Your phone must also be unlocked. You can check under Settings: if you see “Add eSIM” or “Add mobile plan”, it is supported.
Can I keep my WhatsApp and my normal number?
Yes. The eSIM only gives you data. Your normal SIM and number stay in the phone, and WhatsApp keeps working with your usual number.
