South Korea eSIM: on the AREX train from Incheon before the luggage comes out
Korea has some of the fastest mobile networks anywhere, and everything from the subway map to the taxi app to the restaurant queue runs through the phone. The eSIM4 South Korea eSIM is a prepaid tourist eSIM, paid once, from USD 2.98 for a week of high-speed mobile data with no physical SIM card, and it is connected before the AREX train has left Incheon. It runs on the SK network, the largest network in the country, and the email with the QR code arrives within minutes of paying.
Coverage across South Korea
Coverage on the SK network takes in Seoul and every line of its subway underground, Incheon, Busan and Haeundae, Daegu, Gyeongju, Jeonju, the KTX high-speed lines between them, the ski resorts around Pyeongchang and the whole of Jeju Island, with 5G almost everywhere people go. Only on the high trails in Seoraksan and Jirisan and at the far end of the DMZ tours does connectivity thin, on every network, so save the offline map before a hiking day. Naver Map and Kakao Map work better than Google Maps in Korea, and both are lighter on data than you would expect.
Which South Korea eSIM plan to choose
1 GB over 7 days is USD 2.98, enough for maps, messaging and a few photos a day. 5 GB over 30 days is USD 9.98 for a longer stay with photos going home every evening. 20 GB over 30 days is USD 28.98 for a working trip. Unlimited data runs from USD 10.98 for 3 days up to USD 67.98 for 30 days, for anyone who would rather never look at a data counter. Every plan tops up online in about a minute if the trip stretches, and the days only start counting when the eSIM first connects in South Korea, so buy it whenever you like, install your eSIM on Wi-Fi at home and switch on data roaming when you land.
Beyond South Korea on the same trip
Adding Tokyo, Osaka, Taipei or Hong Kong to the same trip? This plan stops at the Korean border. The Asia eSIM covers South Korea, Japan, Taiwan, Hong Kong, China, Singapore, Thailand and eleven more countries on one plan, from USD 3.98 for 1 GB over 7 days, so a Seoul to Osaka to Taipei loop needs one purchase.
Pick a plan, check out and stay connected from the arrivals hall; the QR code will beat you to the suitcase.
Frequently Asked Questions
For nearly every visitor, data is enough. Kakao T taxis, Naver Map and Kakao Map, the Papago translator, the subway apps and Coupang Eats all run on the eSIM data with an email login or your home number, and your home SIM stays in the phone for the one-time codes your bank sends. The one place a Korean number still comes up is the waiting-list kiosk at a handful of popular restaurants, which the host will usually work around if you ask; a Korean-number plan is sold only in person at a carrier counter against your passport, which is a long queue to stand in for a kiosk. Buy the South Korea eSIM at home, install it over Wi-Fi, and it is live when you land, from USD 2.98 for a week.
You can, and the counters in the arrivals hall at Incheon are well run; the cost is a queue after a long flight, a passport check, and a physical SIM card to swap and keep safe for the way home. The South Korea eSIM is a foreign line roaming on SK Telecom: no counter, no passport check and nothing to swap. Buy it at home, install it over Wi-Fi, and your phone connects on the walk from the gate, so the AREX timetable and the hotel address in Naver Map are already on the screen before the luggage comes out.
SK Telecom, the largest network in South Korea, with 5G in Seoul, Incheon, Busan, Daegu and Gwangju, on every line of the Seoul subway and on the KTX between the cities, and 4G everywhere else people go, including the whole of Jeju Island. Your phone should automatically pick the strongest SK Telecom signal as you move between cities, and the same plan works nationwide, from 1 GB over 7 days at USD 2.98 to unlimited data for 3 to 30 days.
An eSIM is a digital SIM built into your phone. Instead of swapping a plastic card, you scan a QR code, or tap one link on a recent iPhone, and the plan installs in about a minute alongside your existing SIM. Your home number stays exactly as it is, and you can switch between plans in Settings whenever you like.
You pay once, from a few dollars, instead of a daily roaming charge, and there is no airport kiosk, no ID check and no card to swap. Buy it at home, install it on Wi-Fi, and you land with maps, ride apps and WhatsApp already working in the arrivals hall. If plans change, every eSIM tops up online in about a minute.
As a guide: 1 GB covers a week of maps, messaging and a few photos a day; 5 GB over a month suits social media and daily browsing; 20 GB or unlimited suits streaming, video calls and working on the road. If in doubt, start small: every plan tops up online in about a minute, so you never pay for data you will not use.
Yes. Our regional plans cover many destinations on one eSIM, so a multi-stop trip needs nothing new at each border: Europe, Asia, Latin America, North America, Africa, Oceania and a World eSIM for trips that cross regions. The countries included are listed on each regional plan page, and you can combine a regional plan with a country plan for the best value.
No. Most people are done in under two minutes: scan the QR code from the activation email, or on iPhone with iOS 17.4 or later simply tap the Direct Installation link in the same email and the eSIM installs itself. Step-by-step guides are here for iPhone guide and Android guide, our support team is on hand, and a refund guarantee covers you if the eSIM cannot be installed on your device.
Most phones from the last five years support eSIM, including every iPhone from the XR onwards and recent Samsung Galaxy and Google Pixel models. Check your model in our compatibility guide before you buy. If your phone was bought on a carrier contract it may need to be unlocked first, which your carrier can do.
Open the activation email, then on iPhone go to Settings, Cellular, Add eSIM and scan the QR code, or tap the Direct Installation link on iOS 17.4 or later. On Android go to Settings, Connections, SIM Manager and scan. Most phones can scan the QR code straight from a screenshot in your photo gallery, so no second phone is needed. Once the eSIM appears in your cellular settings it is installed and ready. Full walkthroughs: iPhone guide and Android guide.
Install it any time before you travel, on Wi-Fi at home: the eSIM does not expire while it sits on your phone. When you land, switch it on and enable data roaming, and your days start counting from that first connection abroad, not from the day you bought it. You can also install on arrival, as long as you have Wi-Fi to download the eSIM.
Yes. Your phone runs as a dual SIM, with your home SIM and the travel eSIM side by side, and most phones store several eSIMs at once with one active for data at a time. Keep a plan for each country on your trip and switch between them in Settings as you cross borders.
Yes. Tethering is included on every plan, so your laptop or a second phone can share the connection whenever you need it.
Your connection pauses rather than charging you more. Top up online in about a minute using the link in your activation email, or in the Yabb app, and you are back online with the same eSIM.
The activation email includes a link to a live usage page for your eSIM, so you can see exactly how much data is left at any time and top up before it runs out.
Top local carriers at up to 5G speeds. The network for this destination is shown above the plans on this page, and the eSIM connects to it automatically when you land.
Choose a 90-day plan where one is offered, or top up your existing plan as you go. Either way the eSIM stays on your phone for the whole trip.
Travel eSIMs are data only, which is exactly why there is no ID or address check to buy one. Everything you normally use runs on the data: WhatsApp, FaceTime, iMessage, Uber, maps and your bank app. If you want a real phone number for calls and SMS abroad, our Yabb app gives you calls, texts and a temporary local number without roaming charges. In a few countries we also sell plans that include a local number, minutes and texts, shown in the plan name; those minutes and texts are for local calls and local texts within that country only.
Yes. WhatsApp, iMessage and Signal stay on your existing number with every chat intact; there is nothing to re-register. The eSIM simply supplies the data they run on.
Yes, with your home SIM left in the phone. The eSIM carries all your data, and most carriers deliver incoming text messages to your home number abroad at no charge, so one-time codes from your bank, Google, Airbnb and the rest arrive exactly as they do at home. Keep the home SIM switched on with data roaming turned off, and only the eSIM uses data. Two things to know before you fly: making a call or sending a text from the home SIM is what triggers roaming charges on most carriers, so leave calling and texting to WhatsApp and the like, and a few carriers do charge for incoming texts or block them abroad, so a quick check with your carrier before you leave settles it.
