How much does an eSIM for Japan cost?

Can I keep my WhatsApp number while using an eSIM in Japan?

Yes! Your WhatsApp number is tied to your original phone number, not your data plan. When you add a travel eSIM for Japan, WhatsApp continues to work with your existing number. Just make sure to set the eSIM as your data line while keeping your original SIM for calls/SMS.

When should I install my Japan eSIM?

We recommend installing your eSIM before departure (you can do this via QR code at home) but only activating it once you arrive in Japan. Most plans start their validity period upon first connection to a local network.

Is my phone compatible with eSIM?

Most phones released after 2020 support eSIM, including iPhone XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, and many other Android devices. Check your phone settings for an 'Add eSIM' or 'Add Cellular Plan' option.

What network coverage will I get in Japan?

Coverage depends on the provider and their local network partners. Most eSIM providers offer 4G LTE coverage in Japan, with 5G available in select areas. Check the provider details above for specific network information.
