Will my eSIM work as soon as I land at Seoul Incheon (ICN)?
Yes. Install the eSIM at home, switch it on when you land at Seoul Incheon (ICN), Seoul Gimpo (GMP), and Busan Gimhae (PUS), and it connects to a local network within a minute or two. You can order a ride or message your hotel before you leave the airport.

Which apps are useful for travelling in South Korea?
Travellers in South Korea commonly use Naver Map, KakaoMap, Kakao T, KakaoTalk, and Papago. They all work over the eSIM data. Sign up and receive any SMS verification codes before you travel, as the eSIM has no phone number.

For maps, messaging and social media, 1 to 3 GB per week is usually enough. If you make video calls, stream or work online, choose 5 GB or more, or an unlimited plan.
Can I buy my South Korea eSIM before I travel?
Yes, and it is the best option: install it at home over Wi-Fi. The plan only starts when your phone first connects to a network in South Korea.
Will WhatsApp still work with my usual number?
Yes. WhatsApp stays linked to your number. Keep your regular SIM on for calls and SMS if you want, and use the eSIM for data.
