eSIM South Korea for Canadians: Seoul, Busan, Jeju (2026)
South Korea eSIM guide for Canadians: skip $16 to $18 a day in roaming, use SK Telecom and LG Uplus 5G, and learn why Naver Map beats Google Maps in Korea.
ArriGo team 12 min read Updated
The best eSIM for South Korea is a prepaid, data-only plan that runs on Korean 5G networks such as SK Telecom and LG Uplus and installs on your phone before you leave Canada. It costs far less than the $16 to $18 a day that Bell, Rogers and Telus charge for roaming in Korea, and it gives you the data you need for Naver Map and KakaoMap, the apps that do the job Google Maps cannot do in Korea.
South Korea is one of the best-connected countries you can visit, but it has a quirk that catches many first-time visitors: Google Maps will not give you walking or driving directions there. This guide covers what roaming in Korea costs Canadians, which Korea eSIM networks to look for, the map apps to install before you fly, how Seoul, Busan and Jeju compare for connectivity, how much data you need, and how to set everything up.
Key takeaways
- South Korea is an international destination for Canadian carriers: $16 a day with Bell and $18 a day with Rogers or Telus, per phone.
- Our South Korea plans connect to SK Telecom and LG Uplus, both with 5G, and the days only start when the eSIM first connects in Korea.
- Google Maps in Korea shows transit routes but no turn-by-turn walking or driving directions. Install Naver Map or KakaoMap, which both have English menus.
- Canadians can visit without a visa for up to 180 days and are exempt from the K-ETA until December 31, 2026, according to the Government of Canada.
How much does roaming in South Korea cost for Canadians?
Bell, Rogers and Telus all bill South Korea at their international rate, which is higher than their US rate. The charge applies on every day your Canadian line uses data abroad, even if all that happens is an app refreshing in the background.
| Carrier and plan | Daily rate in Korea | 7 days | 10 days | 14 days | 21 days |
|---|---|---|---|---|---|
| Bell Roam Better | $16 | $112 | $160 | $224 | $320 (20-day cap) |
| Rogers Roam Like Home | $18 | $126 | $180 | $252 | $378 |
| Telus Easy Roam | $18 | $126 | $180 | $252 | $378 |
Canadian dollars before tax, October 2026 rates, per phone. Bell stops charging after 20 days per line in a billing period, according to its travel page. Rogers also sells an International Travel Pass ($45 for 3 days, $75 for 7, $100 for 14, $120 for 30), which is cheaper than its daily rate on longer trips; details are on Rogers’ roaming page.
Most Korea trips from Canada last a week or more because of the long flight, so the daily rate adds up quickly. A couple spending two weeks between Seoul, Busan and Jeju pays around $450 to $500 in daily roaming charges. The Government of Canada’s advice on using your phone outside Canada warns that phones use data in the background, which is how many travellers trigger a daily charge without opening a single app. Our Bell, Rogers and Telus roaming vs eSIM guide has a calculator for your exact dates.
What is the best eSIM for South Korea?
A good Korea eSIM gives you fast data on a strong local network, installs before you fly and has enough data for a navigation app running most of the day. When you compare plans, check these points:
- Network access: a plan that can use more than one Korean network gives your phone a fallback where one signal is weak.
- 5G: handy in Seoul and Busan, where you will lean on maps, translation and photo uploads.
- Validity that starts on arrival: install at home and land with data ready, without losing days to the flight.
- Hotspot: useful if you carry a laptop or tablet, or want to share data with a travel partner for an afternoon.
- Plan size: match it to the length of the trip and how much time you spend away from Wi-Fi.
Korea has three national mobile operators: SK Telecom, KT and LG Uplus. Our South Korea plans connect to SK Telecom and LG Uplus, both with 5G, and your phone joins whichever has the better signal where you are. Plans are data-only, so your Canadian number stays on the phone for calls and texts.
Each plan page lists its networks and shows whether hotspot is included under “Coverage & networks”. You can see every operator we work with on our mobile networks page. Not sure your phone supports eSIM? Check it with our compatibility checker before you buy.
Does Google Maps work in South Korea?
Only partly, and this is the most important thing to know before you land. According to a Korea Herald report from August 2026, Google Maps in Korea offers place listings, reviews and public transit directions, but no guided navigation for walking or driving. The walking parts of a transit route appear only as a dotted line, without step-by-step directions.
The reason is a long-running dispute over map data. South Korea restricts the export of its high-precision map data on security grounds, and it turned down Google’s requests in 2007 and 2016. The same report says Korea conditionally approved the export of 1:5,000-scale map data to Google on February 27, 2026, and that Google plans to add turn-by-turn navigation, but no launch date has been given. Until that happens, plan your trip around the Korean apps.
Naver Map and KakaoMap: the apps to use instead
Two Korean apps do what Google Maps does at home, and most visitors install both.
| Naver Map | KakaoMap | Google Maps in Korea | |
|---|---|---|---|
| Developer | NAVER Corp. | Kakao Corp. | |
| English menus | Yes (also Japanese and Chinese) | Yes | Yes |
| Public transit routes | Yes, with real-time departures and get-off alerts | Yes, with real-time bus information and a subway map | Yes |
| Walking directions | Yes | Yes | No turn-by-turn guidance |
| Driving navigation | Yes, with live traffic | Yes, turn-by-turn | No |
Features as described on the App Store listings for NAVER Map and KakaoMap, October 2026.
All of these apps need a live data connection to be useful, which is the strongest argument for having a Korea eSIM rather than relying on café Wi-Fi. A few habits make them easier to use:
- Install and set the language at home. Download both apps on Wi-Fi in Canada and switch them to English before you fly.
- Search in Korean when English fails. If a place does not show up, copy its Korean name from your hotel booking or a website and paste it in.
- Keep Google Maps for research. It is still handy for saving places and reading reviews before the trip; just use Naver or Kakao for the route itself.
Tip: Save your hotel’s address in Korean as well as English in your phone’s notes. Showing it to a taxi driver or pasting it into Naver Map is far easier than spelling it out.
Seoul eSIM: getting around the capital
Seoul is a city where you will use your phone constantly: to plan subway and bus transfers, check opening hours, translate menus and find the right exit at large stations. A Seoul eSIM with 5G makes all of that quick, and a plan that can use both SK Telecom and LG Uplus means your phone can switch to the stronger signal as you move between neighbourhoods.
Most visitors split their time between palaces and markets in the old centre, shopping districts and the Han River parks. Naver Map handles transfers between subway lines and buses well, and its alerts tell you when to get off, which helps when station names are announced quickly. If you plan a day trip outside the city, check the route on the app before you leave the hotel, while you can still ask the front desk for help.
Busan and Jeju: coast, islands and coverage
Busan is South Korea’s big port city on the southeast coast, known for its beaches, seafood markets and hillside neighbourhoods such as Gamcheon Culture Village. A Busan eSIM works the same way as in Seoul: the same plan covers the whole country, so you do not need a new one when you change cities.
Jeju is a volcanic island off the south coast and one of Korea’s most popular holiday spots. In towns and along the main coastal roads you can expect normal mobile service, but signal can weaken on hiking trails, in forests and on the slopes of Hallasan, the island’s central mountain. Before a hike, download what you need while you have a strong signal and tell someone your route.
A few tips for the coast and the islands:
- Ferries and flights: if you are hopping between Busan, Jeju and smaller islands, check departure times on the day, since sea conditions can change schedules.
- Car rental on Jeju: both Naver Map and KakaoMap offer driving navigation in English, so you do not need to rent a separate GPS unit. Google Maps will not guide you while driving.
- Hotspot for a group: if you are driving with friends or family, one phone with hotspot can serve as the car’s navigation and music source. Check that your plan includes hotspot.
How much data do you need in South Korea?
Korea is a data-heavy trip. Navigation apps run most of the day, translation apps use your camera, and fast 5G makes it tempting to upload photos and video as you go. As a rough guide for one phone:
| Type of trip | Typical use | Suggested data |
|---|---|---|
| One week in Seoul, hotel Wi-Fi at night | Maps, transit, messages, some photos | 3 to 5 GB |
| Two weeks: Seoul, Busan and Jeju | Daily navigation, translation, social media | 5 to 10 GB |
| Three weeks or longer, including road trips | Heavy maps use, video calls home, photo uploads | 10 to 20 GB |
| Working remotely or sharing a hotspot | Video calls, cloud files, large uploads | 20 GB or more |
Video is the biggest drain, so streaming and short-video apps will use far more than maps. To stretch your plan:
- Set photo backups to Wi-Fi only.
- Turn off background refresh for apps you will not use on the trip.
- Download Korean in your translation app so text translation still works offline.
Our guide to how much data you need when travelling explains what each type of app uses. If you are wondering whether 5G matters on holiday, see 5G vs 4G when travelling.
Entry rules for Canadians: K-ETA and the e-Arrival card
The Government of Canada’s travel advice for South Korea says Canadians do not need a tourist visa for stays of up to 180 days. It also says Canadians are exempt from the Korea Electronic Travel Authority (K-ETA) until December 31, 2026. If your trip is in 2027, check that page and the official K-ETA website again before you book, because the exemption has a fixed end date.
All travellers must submit an arrival declaration, either online in the three days before arrival or on paper when you land. The online form is on the official e-Arrival card site, and the Canadian travel advice notes the service is free, so avoid any website that charges a fee. Filling it in before the flight, while you are on home Wi-Fi, saves time at the airport.
The same page lists these emergency numbers, with English interpretation available:
- Police: 112
- Ambulance and fire: 119
It also notes that some ATMs from major banks accept foreign cards but may set a low limit per withdrawal, which makes fees add up. Your map app can help you find a bank ATM near your hotel before you run low on cash.
How to set up your Korea eSIM before you fly
Setting up takes about five minutes, and the best place to do it is at home on your own Wi-Fi. The plan’s days only start when the eSIM first connects to a network in South Korea, so installing it early costs you nothing.
- Check your phone. It must support eSIM and be unlocked. Our compatibility checker lists supported models.
- Buy your South Korea plan. The QR code arrives by email, usually within about a minute. Travelling as a family? You can buy up to 10 eSIMs in one order and send each QR code to its own email.
- Install it on Wi-Fi. On iPhone, follow Apple’s eSIM setup guide. On Android, open Settings, look for SIM manager or Network and internet, and add an eSIM by scanning the code.
- Label your lines. Name the new line “Korea” and your usual one “Canada”.
- Download Naver Map and KakaoMap while you are still at home, and set both to English.
- When you land, turn on the Korea line, switch on data roaming for it and choose it as your mobile data line.
- Turn data roaming off on your Canadian line so your carrier cannot start a daily charge.
With dual SIM, your Canadian number can stay active for calls and texts, including bank verification codes, while all your data runs through the Korea eSIM. Our guide to keeping your Canadian number with a dual SIM eSIM explains how. A data-only eSIM does not give you a Korean phone number, so if a local service asks for one, use your hotel’s number or ask staff for help. For step-by-step installation on every phone, read how to install an eSIM before you fly, and if something does not connect after landing, our help centre has the fixes.
Combining Korea with Japan or the rest of Asia
Many Canadians pair Seoul with Tokyo or Osaka, since the flights between them are short. A South Korea plan covers Korea only, so you will need separate data for the next country. Our Japan eSIM guide covers the Japanese networks, and you can find plans for other stops, such as Vietnam or Thailand, in our destinations list. For a longer multi-country route, compare our global plans.
Your next step
Check that your phone supports eSIM with our compatibility checker, then compare every South Korea eSIM plan by data and validity. Install it at home, download Naver Map and KakaoMap on Wi-Fi, file your e-Arrival card, and switch the eSIM on when you land at Incheon.
Frequently asked questions
Which network does a South Korea eSIM use?
Our South Korea plans connect to SK Telecom and LG Uplus, both with 5G. Your phone joins whichever of the two has the better signal where you are, so you are not tied to a single operator.
Does Google Maps work in South Korea?
Partly. Google Maps shows places, reviews and public transit routes in Korea, but it does not offer turn-by-turn walking or driving navigation. Most visitors install Naver Map or KakaoMap, both of which have English menus and full navigation.
Do Canadians need a K-ETA to visit South Korea?
Not for now. The Government of Canada says Canadians are exempt from the K-ETA requirement until December 31, 2026, and can visit without a visa for up to 180 days. Check the official travel advice again if your trip is in 2027 or later.
Do I get a Korean phone number with a travel eSIM?
No. Our plans are data-only, so your Canadian number stays on your phone for calls and texts. Apps such as KakaoTalk, WhatsApp, iMessage and FaceTime work normally over the eSIM data.
How much data do I need for two weeks in South Korea?
As a rough guide, two weeks with hotel Wi-Fi at night needs about 5 to 10 GB per phone for maps, transit, translation and messages. Choose more if you post a lot of video or share a hotspot with a laptop.
Can I install my Korea eSIM in Canada before I fly?
Yes, and it is the best way to do it. Install it at home on Wi-Fi; the plan's days only start counting when the eSIM first connects to a network in South Korea.
