This eSIM gives you mobile data in Japan and South Korea without switching eSIMs, which makes it handy for a trip that combines both countries. In Japan it connects to au (KDDI) and SoftBank, in South Korea to SK Telecom and LG Uplus, with 4G and 5G where the network offers it. Coverage is excellent in cities such as Tokyo, Kyoto, Osaka, Seoul and Busan, and you usually stay connected along the shinkansen and KTX rail lines too. NTT Docomo and KT are not used by this eSIM, but the networks it does use cover the usual tourist routes well, including Hokkaido, Okinawa and Jeju. Networks: au (KDDI), SoftBank, SK Telecom, LG Uplus.
For a short stopover, 1 GB (valid for 7 days) or 3 GB is usually enough. For a two-week trip through both countries, 10 GB (valid for 30 days) works well if you use hotel wifi in the evening for video and large downloads.
Japan and South Korea are outside the EU roaming rules, and many home plans charge separate roaming rates or day passes there. With this eSIM you arrange your data for both countries in advance, separate from your home plan.

No. Keep data roaming switched on for the eSIM and it will pick a Korean network by itself after landing, usually within a few minutes. If it does not connect straight away, turn airplane mode on and off again.
In Japan Google Maps works very well, including for trains and the metro. In South Korea Google Maps does not yet offer full turn-by-turn walking or driving navigation. Install Naver Map, which has an English version, or Kakao Map instead. These apps need mobile data on the go.
For navigation, translation apps and social media, count on roughly 0.5 to 1 GB per day. A week usually needs about 5 GB, and two weeks with hotel wifi around 10 GB. If you need much more data in one country, there are also separate eSIMs for Japan and South Korea with larger bundles.
