What should I know before a trip to South Korea?
In South Korea the plan runs on SK Telecom and LG U+, both with 5G. Coverage is among the best in the world, including in the metro and on high-speed trains.
Google Maps doesn't give full walking and driving directions in Korea, so most travellers use Naver Map or KakaoMap. Taxis are booked through Kakao T, and the metro and buses are paid with a T-money card.
Frequently Asked Questions

Are eSIM, digital SIM, and virtual SIM all the same thing?
Yes. An eSIM (also called a digital SIM or virtual SIM) is a SIM with no physical component, installed on your device by scanning a QR code instead of inserting a card. You use it exactly like a regular SIM for data abroad, without hunting for a SIM kiosk at your destination.
Does my device support eSIM technology?
Most smartphones released in the last five years support eSIM. We recommend checking your device settings, or looking up your phone model in the FlySim compatibility checker. Open the compatibility checker
How exactly does activation work?
After payment, you'll receive a unique QR code by email. Scan it in your device's cellular settings (Add eSIM), confirm, and that's it.
