Japan & South Korea eSIM — frequently asked questions
Everything travelers ask before buying a Japan & South Korea data plan.
How do I activate my Japan & South Korea eSIM?
After purchase you'll receive a QR code by email. Scan it from your phone's cellular settings to install the Japan & South Korea eSIM. Install over a reliable internet connection, then follow the activation instructions supplied with your plan.
Does my phone support eSIM in Japan & South Korea?
Your phone must support eSIM and be carrier-unlocked. Support varies by exact model and the country where the phone was sold, so check your model and regional variant in our compatibility checker before buying.
Can I keep my regular phone number?
Yes. The Wanderly Japan & South Korea eSIM runs as a secondary line alongside your primary SIM, so you keep calls and texts on your home number while using mobile data from the eSIM. Your home carrier may still charge for calls and texts abroad; disable data roaming and automatic data switching on the home line.

Not for Japan & South Korea yet — the plans here are data-only, so keep your home SIM active for calls and texts, or use WhatsApp, FaceTime and other apps over the eSIM's data. We do sell plans that include a phone number for many other destinations.
