South Korea travel eSIM comparison
Korean eSIMs ride KT, SK Telecom or LG U+ — city speeds are excellent everywhere including subway platforms. One local quirk matters more than the SIM itself: Google Maps barely works for walking/driving directions here, so install Naver Map or KakaoMap before you land.
Cheapest right now: Airalo KR · 1GB · 3 days at HK$31.79 per month.
What matters here
- Full data coverage on Seoul subway lines and platforms
- Use Naver Map / KakaoMap — Google Maps navigation is unreliable
- No Korean registration needed for tourist data SIMs

FAQs
Why doesn't Google Maps work properly in Korea?
Korean law restricts exporting detailed mapping data, so Google's walking/driving directions are limited. Naver Map and KakaoMap have full data and English interfaces — download them before arrival.
Do I need a separate T-money card if I have a data eSIM?
Yes for transit fares — Korean subways/buses charge by tap-in, and mobile payments via foreign cards aren't widely accepted on them. A physical or Climate Card handles transport; the eSIM handles everything online.
