South Korea eSIM.
Seoul's palaces to Busan's beaches and Jeju's volcanic coast — online the whole trip.
Every plan: QR by email in minutes · data-only, keep your number · days start on first connection · top up anytime · the total shown is the whole bill. What's included →
Unlimited plans run at full speed up to a daily fair-use allowance, then at reduced speed until the allowance resets the next day — you're never cut off. Every plan is prepaid: the checkout total is the whole bill, and we never add overage charges.
Hotspot support varies by plan and destination — where it's available for your plan in South Korea, it's shown in the plan details before you pay.
The South Korea eSIM guide.
South Korea runs on its own apps: KakaoMap and Naver Map for getting around, KakaoTalk for messaging, Kakao T for taxis and Papago for translation — and Google Maps barely works here. Data keeps them all live, from KTX bookings to late-night Hongdae plans and photos back to the family chat.
How it works on the day
Scan the QR at home over Wi-Fi, then switch the eSIM on as you land at Incheon (ICN), Gimpo (GMP) or Busan Gimhae (PUS). It latches onto a major Korean network — SK Telecom, KT or LG U+ — automatically, while your home number stays live for texts.
Choosing your days
A 5-day plan covers a Seoul city break comfortably; 10 to 14 days suits the classic Seoul–Busan–Jeju run down the KTX line and brings the per-day rate down — the usual pick for pairing the cities with the coast.
Discover South Korea.
The short version.
A travel eSIM is data only. It sits next to your home SIM, so your number, texts and WhatsApp carry on as normal. Pick unlimited, priced per day, or a fixed bundle of GB if it's mostly maps and messages. Install it on Wi-Fi before you fly — the days only start once it first connects in South Korea, and it finds a partner network on its own.
