South Korea has some of the fastest 5G in the world and cheap unlimited travel eSIMs are abundant. WiFi is everywhere in Seoul and Busan, but a data plan is still essential for maps, KakaoTalk, Naver Maps and translation.

Tips for data usage in South Korea
- Unlimited plans are very competitively priced in Korea — often cheaper than a 10 GB capped plan in Western Europe.
- Most unlimited tourist plans throttle to 3–5 Mbps after a daily high-speed cap (commonly 500 MB–1 GB/day), which is still fine for maps and social.
- KakaoTalk and Naver Maps work best on a local IP, which a Korean eSIM gives you.
Major networks: SK Telecom, KT, LG U+. Unlimited data plans (often throttled after a daily cap) for 3–30 days, plus high-speed 1–20 GB options.
