eSIM for South Korea
Plans from $1.95 per day
South Korea
Korean plans run on KT and SK Telecom partner networks — and South Korea has some of the fastest, most pervasive 5G on the planet, blanketing Seoul, Busan, and Incheon and the subway systems travelers use constantly.
An eSIM lets you tap those speeds without queuing at an airport pickup counter or handing over your passport for registration. From the moment you land you're set for Naver Map and KakaoMap navigation, T-money transit top-ups, and translation — all data-heavy and all smoother on a fast connection.
Coverage is excellent essentially everywhere a visitor goes, including high-speed KTX trains and Jeju Island. With hotspot supported, a single plan can also keep a laptop online for remote work. Install at home and it activates automatically on first connection to a Korean network.

Why eSIM here, not a local SIM

Free Wi-Fi: Widely available. South Korea has some of the world's fastest 5G — eSIM users get full access to those speeds without needing to interact with a Korean carrier in person.

Common questions about South Korea
When does my plan's validity start in South Korea?
Validity starts when your eSIM first connects to a local South Korea network, that's usually as soon as you land and switch off airplane mode. Installing the eSIM at home days before your trip doesn't burn any days.
Can I use my phone as a Wi-Fi hotspot in South Korea?
Yes, all Esim70 plans support tethering by default with no separate daily cap. Your phone can share its data connection with a laptop, tablet, or travel companion's phone.
Will my home number still work in South Korea?
Yes, modern phones support dual-SIM. Your home SIM stays active for calls and SMS while the Esim70 eSIM handles data abroad. You can keep WhatsApp / iMessage tied to your home number too.
