South Korea
Useful apps for South Korea: transport, maps, translation
Install Naver Map or Kakao Map for routes, Kakao T for taxis, Papago for translation and Korail Talk for trains before you fly; Google Maps runs in Korea but gives limited walking and driving directions, so treat it as a backup. Add a card app with travel notifications and you can land at Incheon ready.

Details
Set up your phone before departure, not in the arrivals hall. Download Naver Map or Kakao Map, Kakao T, Papago and Korail Talk over home Wi-Fi, create any accounts you can, and add a payment card to the taxi app. Korean apps often ask for a phone number at sign-up; if you are buying a tourist SIM or eSIM with a local number, do that first, then register. Data-only eSIMs work for maps and translation but can block apps that verify identity by SMS.
Naver Map and Kakao Map are the two that actually route you in Korea. Both cover subway, bus, walking and driving, show live arrival times and handle Korean addresses, which Google often cannot. Pick one and learn it: search in English usually works for landmarks and station names, but typing the Korean name gives better results. Kakao Map pairs naturally with Kakao T, the taxi app almost every Korean uses.
Kakao T calls a regular metered taxi, shows the fare estimate and lets you pay in-app or in the car. Uber also operates in Korea, mostly with the same licensed taxis, so it is a reasonable fallback if your card will not link to Kakao T. At Seoul stations and airports, follow the taxi rank signs rather than hailing on the street.
Papago, made by Naver, is the translation app to use for Korean. It handles menus, signs and short sentences better than general-purpose translators, and has a camera mode for reading labels. For anything longer, keep sentences short and show the screen rather than reading aloud.
For trains, Korail Talk covers KTX, ITX and regular services, with seat selection and mobile tickets. SRT is a separate operator on the Suseo–Busan line and has its own app. Both are in Korean-first interfaces; English is available but thinner. If an app defeats you, tickets are also sold at station counters and machines with a passport.
Two practical extras: a banking or card app with travel notifications switched on, so a blocked card does not strand you, and a messaging app. KakaoTalk is what Koreans use; WhatsApp mostly connects you with other foreigners. Neither is required to travel, but both make meeting people and booking things easier.
| Need | App | Notes |
|---|---|---|
| Maps and routes | Naver Map or Kakao Map | Best coverage of Korean addresses; English search works for landmarks |
| Taxi | Kakao T | Metered taxis, fare estimate, in-app payment; Uber as fallback |
| Translation | Papago | Camera mode for menus and signs; better Korean than general translators |
| Trains | Korail Talk / SRT | KTX and regular trains; SRT for the Suseo line; counters sell tickets too |
| Messaging | KakaoTalk | Standard in Korea; WhatsApp mostly with foreigners |
| Payments | Your bank or card app | Turn on travel notifications before you fly |
| Getting online | SIM or eSIM | A local number helps with app sign-ups; data-only is cheapest |
All apps are free to download; you pay only for data. Interfaces and English support change — check before you rely on one.
Tips
Download everything before you fly and log in once at home, so a verification SMS reaches you on a familiar network.
Screenshot your hotel address in Korean and show it to the taxi driver; Kakao T lets you set the destination in the app, which avoids the conversation entirely.
If an app refuses your foreign card, try another card or pay the driver directly — most taxis take cards.
Keep Google Maps installed as a backup for reviews and opening hours, but do not trust it for turn-by-turn directions in Korea.
Free public Wi-Fi is common on the subway and in cafés, but do not depend on it for a taxi at midnight; have data.
FAQ
Questions people ask
Which apps do I need in South Korea?
Naver Map or Kakao Map for routes, Kakao T for taxis, Papago for translation and Korail Talk for trains. Add a card app with travel notifications and a messaging app such as KakaoTalk. All are free; you pay for data through your SIM or eSIM.
Does Uber or a local taxi app work in South Korea?
Both. Kakao T is the local standard and calls metered taxis with fare estimates and in-app payment. Uber also operates in Korea, largely with the same licensed taxis, and is a useful fallback if your card will not link to Kakao T.
Does Google Maps work well in South Korea?
It runs, but directions are limited in Korea, so walking and driving routes are unreliable. Use Naver Map or Kakao Map for navigation and keep Google Maps as a backup for reviews and opening hours.
Do I need a Korean phone number for these apps?
Not for maps, translation or basic taxi use, but some apps and identity checks ask for a local number at sign-up. A tourist SIM or eSIM with a Korean number avoids most of these blocks; data-only plans are cheapest but can fail SMS verification.
Can I buy train tickets without the Korail app?
Yes. Korail Talk and the SRT app are convenient, but station counters and ticket machines sell the same seats, and staff can help in English at major stations. Bring your passport for identification.
