Will my eSIM have signal in South Korea?
Your eSIM joins LG Uplus and SKTelecom in South Korea, and both networks offer 5G. Your phone picks between them by itself, so there's no network to choose. Signal is excellent nearly everywhere, including the subway and most rural areas, so maps and KakaoTalk are close at hand.
Your data reaches the internet through Singapore, which is a normal setup for travel eSIMs, so nothing extra is needed from you. Read more on the IP address help page. If you pick a daily plan, speeds slow to 512 Kbps once that day's allowance is used up.

Using your phone in South Korea: data tips
- Land and switch on: Install your eSIM at home on Wi-Fi, then switch it on when you land at Incheon (ICN), Gimpo (GMP) or Gimhae (PUS). Keep data roaming turned on for the eSIM line.
- Getting around: Naver Map and KakaoMap give walking and transit directions, so save both before you leave. For rides, Kakao T and Uber are the apps to have ready.
- Staying in touch: KakaoTalk is the messaging app to download before you fly. Your home number stays on for calls and texts, and the help page shows how to keep your chats going.
- Sign-up tip: Many Korean apps ask for a local phone number to sign up, which a travel eSIM may not provide. Check that step before you count on an app.
- Data: Light use with maps and messages is about 0.25 GB a day, so check how much data you need before you pick a plan.

Which networks does the South Korea eSIM use?

Can I top up my South Korea eSIM?

Why does my IP address show another country?
South Korea plans route your data through Singapore, a normal setup for travel eSIMs. Websites and apps may show that country's content; your speed and coverage in South Korea are not affected.
Does it come with a phone number?
Every eSIMology plan is data only. Keep your own SIM switched on for calls and texts, and use WhatsApp, FaceTime or any calling app over your eSIM's data.
What if my plans change?
Cancel an eSIM you haven't installed within 30 days for a full refund to your card, in two taps from your eSIM page.
Is there 5G in South Korea with an eSIM?
Yes. South Korea's networks offer 5G, so your eSIM can connect over 5G wherever the signal is there. Check that your phone supports 5G before you fly, so you're ready to use it.
Which eSIM covers both Japan and South Korea?
Japan & South Korea covers both countries on one eSIM, so you won't need to swap plans when you fly between them. If China is on your route too, China, Japan & South Korea covers all three.
Do Naver Map and KakaoMap work in South Korea?
Naver Map and KakaoMap give walking and transit directions in South Korea where Google Maps can't. Download both before you fly, so you have them ready when you land at Incheon (ICN) or Gimpo (GMP).
Can I use KakaoTalk in South Korea on an eSIM?
Yes, KakaoTalk runs on your eSIM data, and it's the messaging app to have on your phone in South Korea. One catch: many Korean apps ask for a local phone number when you sign up, and a travel eSIM may not provide one, so set up your accounts before you leave home.
Which ride apps work in South Korea with an eSIM?
Kakao T and Uber are the two ride apps to have on your phone in South Korea. Both need mobile data to book, so turn on your eSIM before you leave the arrivals hall at Incheon (ICN), Gimpo (GMP) or Gimhae (PUS).
What happens when my daily data runs out in South Korea?
Your speed drops to 512 Kbps, which is still enough for messages and maps. If you plan to stream video on a busy day in Seoul, choose a bigger daily allowance before you go.
