Frequently Asked Questions about eSIM for Japan

What is an eSIM and how does it work?

An eSIM (embedded SIM) is a digital SIM card built into your smartphone. Instead of inserting a physical chip, you scan a QR code or download a profile to connect to a mobile network in Japan. It works exactly like a regular SIM for data but without swapping cards.

Is my phone compatible with eSIM?

Most newer smartphones support eSIM, including iPhone XS and later, Samsung Galaxy S20 and later, Google Pixel 3 and later, and many more. Check your phone settings or manufacturer website to confirm eSIM compatibility.

Can I keep my WhatsApp number?

Yes! Your WhatsApp account is linked to your phone number, not your SIM card. When you activate your eSIM data in Japan, WhatsApp will continue working exactly as before.

When should I activate my eSIM?

Most eSIM providers recommend installing the eSIM before your trip while you still have a stable Wi-Fi connection. The data plan usually starts counting when you first connect to a network in Japan.
