Coreia do Sul — 6 GB plan
6GB
30 days·Data only·Reloadable
Destination
One eSIM covering Coreia do Sul. Add another destination and it joins the same plan — you never install a second eSIM, and between trips it costs nothing.
Choose your dataMost of the ground is covered by KTX - Seoul to Busan in a couple of hours, Gyeongju slotted in along the way - with Jeju bolted on as a flight. The thing people arrive unprepared for is that Google Maps gives no walking or transit directions here, so the trip runs on Naver Map or KakaoMap, and on Kakao T once the subway stops for the night.

Prices in USD, shown before tax. Data only — no calls or SMS. Run out and you can reload the same eSIM, no need to install a new one.
What the plan covers, and what is worth sorting out before you fly.
Install Naver Map or KakaoMap before you fly and search one real address in it - arrivals at Incheon is not where you want to be learning how it handles English.
Add a country and it joins this plan. No second eSIM to install, no second bill to reconcile, and the same number of profiles on your phone as when you started.
Pick a size, use it, top it up from the browser when you need more. Nothing renews on its own and nothing expires the day you land home.
A person, 24/7, in the language you booked in. Not a chatbot, and not a form that answers on Monday.
How it works
Pick your destinations and buy the plan. Nothing to download.
Scan the QR code to install the eSIM. Do it before you fly.
Land already connected. No hunting for a SIM at the airport.
Add a destination and see what one plan covering both costs. It stays the same eSIM.
