South Korea eSIM plans at a glance
Wanderly lists 51 fixed-data South Korea plans, ranging from 1GB up to 50GB over 7 to 365 days. Prices start at $1.99, and the lowest cost per gigabyte is $0.47/GB on the 50GB 30-day plan.
Unlimited day-passes are also available from $1.99 per day, billed per day rather than per gigabyte. All 67 South Korea plans can be topped up without reinstalling the eSIM.
Every plan is data-only and installs from a QR code, so your home number stays active on its own line. Validity starts when the eSIM first connects to a network in South Korea, not at purchase, which means you can install before you fly.
🇰🇷 About eSIMs in South Korea
South Korea has the fastest 5G network on the planet, and Wanderly connects you to it. Plans run on SK Telecom or KT, which together cover Seoul, Busan, Jeju and the entire high-speed rail corridor with near-flawless signal. Real-world speeds in Gangnam and Hongdae regularly exceed 500 Mbps.
Korea leans hard on apps. You will use Naver Maps and KakaoMap far more than Google Maps (Google is deliberately restricted for mapping in Korea), and Papago for translation. That means constant data — plan on 8–10 GB per week for a normal itinerary, more if you rely on video calls or K-drama streaming on the KTX.
Airport pickup SIMs at Incheon are quick but often twice the price of an eSIM you install in advance. Wanderly delivers the QR by email within a minute; you scan it once, arrive, and connect the moment you clear immigration.
How to activate your eSIM in South Korea
- 1Order in advanceBuy your Korea eSIM before departure — you cannot install one reliably without Wi-Fi, and airport Wi-Fi at ICN can be crowded.
- 2Install and labelScan the QR from Settings and label the profile ‘Korea’. Keep your home SIM active for iMessage and 2FA codes.
- 3Activate on arrivalToggle airplane mode after landing, set Cellular Data to the Korea eSIM, and enable Data Roaming. This is required for eSIMs and does not incur roaming charges.
- 4Grab Naver MapsDownload Naver Maps or KakaoMap. Google Maps is unreliable for walking directions inside Korea due to national mapping rules.
