About South Korea eSIM coverage
Coverage & Networks
4G/LTE and 5G via SK Telecom, KT and LG U+ — World-class 5G everywhere — the underground, mountain trails and even ferry crossings. South Korea consistently ranks among the fastest mobile networks globally.
How much data do I need?
2–5 GB covers a week of Seoul underground navigation, K-drama streaming and social media. Heavy map use in Busan and Jeju adds up; opt for more if you're a streamer.
Tip for South Korea
Install Naver Maps before arriving — it's far more accurate than Google Maps for Korean addresses, public transport and local dining reviews.
