Questions fréquentes

How does an eSIM help with sightseeing in Japan & South Korea?

At Haneda Airport, you walk past the SIM counter queue and open Google Maps for the train into Tokyo. Your eSIM gives you data without that extra stop. On the ride, you trace the route to Asakusa and save the address of a ramen shop. Outside the station, Google Translate helps you read the menu, and you send a photo of your bowl home through WhatsApp.

Your Japan & South Korea route continues in Seoul, where you open NAVER Map to find your way through Jongno to a courtyard cafe. You book a palace tour, then use KakaoTalk to message a friend about where to meet. Back in Tokyo for your final stop, you use Uber to arrange a ride and Uber Eats to order dinner to your accommodation, following the delivery progress while you sort your photos.

What should tourists look for in a Japan & South Korea eSIM?

For Japan & South Korea, look for a regional eSIM that covers both countries and the routes between your sightseeing stops. This plan covers both, with its strongest reach in cities and main tourist areas. Hotspot works on most plans, and you can top up with more data when needed.

Choose an option you can prepare before flying. This eSIM installs in one tap from the button in your order email, with 180 days from purchase to activate. It is data-only, and the data allowance and validity depend on the package you choose.

Where does the Japan & South Korea eSIM have coverage?

Your Japan & South Korea eSIM connects to local networks including KDDI/au, SoftBank, SKTelecom, LG Uplus, with 3G/4G/5G coverage.

What digital travel tips help in Japan & South Korea?

  • Save accommodation addresses in Japanese and Korean, plus screenshots of booking confirmations, so you can show them without loading a page.
  • Download offline walking maps for Japan; save route screenshots for South Korea, where offline navigation options are more limited.
  • Bring an adapter for Japan’s Type A sockets and South Korea’s Type C or F sockets; check your charger supports both voltages.
  • Carry a physical payment card and cash in Japan & South Korea; small restaurants and market stalls do not all accept mobile wallets.
  • Set your phone to silent on trains in Japan and South Korea, and use headphones for navigation audio.
  • Keep a power bank insulated during winter sightseeing in Seoul; cold weather drains phone batteries faster.
