9 Apps to Download Before You Visit South Korea
Before you fly to South Korea, download a local map app such as Naver Map or KakaoMap, a taxi app, a translator and a travel eSIM, because Google Maps directions are limited there. Do the downloads on home Wi-Fi so everything is ready when you land.
Updated 27 October 2026
This list is for first-time and returning visitors to South Korea who want to land and move without fuss. Start with the entry rules and your airline app, then work down the list so each tool is installed and set up before you leave home.
1. Check entry rules officially
Entry requirements depend on your passport, and some travellers need an electronic travel authorisation before boarding. Finding out at the check-in desk is the most expensive way to learn.
How: Open the official South Korean government and immigration sites for your passport country and confirm what applies to you. Do it before you book anything non-refundable.
Tip: Screenshot any approval or confirmation so it opens without a signal.
2. Your airline's app
Gate changes, delays and baggage updates arrive in the app first, which matters at a big international airport where signs are busy.
How: Download the app, sign in with your booking reference and turn on notifications for the flight. Add the boarding pass to your phone wallet once check-in opens.
3. A travel eSIM, installed before you fly
Every other app on this list works better with data the moment you land, and you do not have to hunt for a SIM counter after a long flight. Fresim creator stores sell travel eSIMs, delivered by email with one-tap install buttons (Install on iPhone, iOS 17.4+ / Install on Android, Android 10+).
How: Buy from a creator store, open the delivery email on your phone and tap the Install button for your device. Follow the activation steps in the email so data switches on when you arrive.
Tip: The QR code in the email is handy if you want to install from a second screen or share it with a travel partner.
4. Naver Map
Google Maps gives limited directions in South Korea, while Naver Map is built for local walking, bus and subway routes and has detailed place listings. It is the one you will open most.
How: Install Naver Map, set the language to English in settings and search for your hotel. Save your hotel, the airport and a few sights as favourites.
Tip: Download offline map data over Wi-Fi if the app offers it for your area.
5. KakaoMap as a second opinion
Local map apps sometimes disagree on a route or a business location, and a second app settles it quickly. KakaoMap is widely used by locals, so its listings are current.
How: Install KakaoMap and search for the same hotel you saved in Naver Map. Compare the transit route the first time you plan a day out.
6. KakaoT for taxis
Hailing a taxi in a language you do not speak is stressful, and KakaoT lets you set the pickup and destination on a map instead of explaining them.
How: Install KakaoT, create your account and check which payment options are available to you before you travel. Keep your destination saved as a pin so the driver sees the exact spot.
Tip: Some features may be limited for foreign phone numbers or cards, so test the sign-up at home.
7. Papago translator
Papago, from the company behind Naver, is designed for Korean and handles menus, signs and short conversations well. Camera translation means you can point at a menu instead of typing it.
How: Install Papago, then try the camera and voice features once at home so you know where they are. Download any offline language option it offers.
Tip: Keep Google Translate installed as a backup for a second opinion on tricky phrases.
8. Phone wallet and bank notice
Cards and phone payments are common in South Korea, but a bank that blocks a foreign transaction can leave you stuck at a till. Setting this up early avoids that.
How: Add your card to Apple Wallet or Google Wallet and tell your bank your travel dates in its app. Carry a backup card kept separate from your main one.
Tip: Check whether your card charges foreign transaction fees before you go.
9. Addresses saved in Korean
Taxi drivers and hotel staff can read Korean addresses instantly, and your map app may not recognise an English spelling of a small guesthouse.
How: Copy the Korean name and address from your booking confirmation or the map listing into a note and screenshot it. Do the same for each place you are staying.
Tip: Add the phone number of each stay to the same note.
Staying connected
The easiest way to have data on arrival is a travel eSIM: Fresim creator stores deliver it by email, and you tap Install on iPhone (iOS 17.4+) or Install on Android (Android 10+) to set it up. The QR code in the same email is a second option, useful for installing from another screen or sharing the eSIM with a travel partner. Do it on home Wi-Fi so your map, taxi and translation apps are ready the moment you land.
