How much does data for your trip actually cost?

Pick your trip length and compare Airalo, Holafly, and Klook side by side — real plan prices, not marketing "from" numbers.

Heads up — all plans here are unlimited-data tourist eSIMs on Korean carrier networks (SKT / KT / LG U+). Prices shift with promotions, so treat these as a starting comparison and confirm the final price at checkout. SKT tourist plans are typically capped around 10 Mbps — fine for maps and messaging, noticeably slower for heavy streaming.

📖 Not sure if you even need a Korean phone number? Read How to Get a SIM Card or eSIM in Korea (2026 Guide) — covers the 2026 verification rules and which option fits your trip.

✈️ Landing soon? Your eSIM activates the moment you touch down, which means the next two decisions come fast: how to get from Incheon Airport into Seoul (the fastest option usually isn't the right one) and which transit card to buy. If you fall ill mid-trip, seeing a doctor in Korea is cheaper and faster than most visitors expect.

🏠 Staying longer than a holiday? A data-only eSIM stops being enough once you need a real Korean number. That runs through your Residence Card, then a bank account and somewhere to live. The Moving to Korea checklist puts them in the right order.
