Essential Apps for Korea

Which apps speak your language

English is the safe bet: all six offer it. Japanese and Chinese are patchier, and it is worth knowing where the gaps are before you count on a map you cannot read.

Naver Map picks up your phone's language, or whichever one you set inside the app. It also runs visitor reviews through Papago, so a Korean review reads in English, Japanese or Chinese, and the restaurant filters come translated as well (NAVER, October 2024).

Phone numbers and sign-up

KakaoTalk checks your phone number with a text message. Kakao's help centre says the code can be slow to reach some countries, depending on the carrier, and to contact them if nothing has arrived within 24 hours. Sometimes it asks you to send the text yourself instead. That fails if your plan will not send messages abroad.

Kakao T runs on the same Kakao account and verifies the number you will use, again by text. Do both before you fly, while your home SIM is still in the phone - a data-only eSIM cannot take verification texts.

Naver went another way. Since 4 June 2026, visitors with a passport issued outside Korea can verify their identity with it, then book, order and pay through Naver Map without a Korean mobile number (NAVER, 9 June 2026).

Kakao T with a foreign card, or none at all

Kakao T takes credit and debit cards issued abroad on Visa, Mastercard, JCB and AMEX. Kakao Mobility lists them for taxis, bikes and its pet service only, so the trains, buses and parking sold in the same app are out. With a card registered and auto-pay on, the fare is charged when you get out.

You can skip the card altogether. Choose a Regular taxi, set the payment to Pay to the driver, and settle up in the car with cash, a card or a Tmoney card. That option exists on Regular calls only.

If the Kakao account is the wall, Kakao Mobility has a separate app for visitors, k.ride. It needs no KakaoTalk sign-up, accepts a Google or Apple login and overseas credit cards, and runs in English, Japanese and both forms of Chinese (VisitKorea).

The extras that earn their place

Papago translates between 14 languages from typed text, photos, handwriting or speech, and text translation keeps working offline - handy when your data runs out halfway through a menu. Photograph a Korean dish name and it pulls the dish's details from VisitKorea. Since April 2026, photo translations can also show restaurant and shop information from Naver Place (NAVER, October 2026).

KakaoMap's best trick for a visitor is Road View. Search a route and you can look at the street around the place before you set off, which helps when the door you want is down a side alley. Naver Map, for its part, has extended real-time subway information beyond Seoul and Busan and added ferry routes (VisitKorea, May 2025).

Subway Korea covers five networks - Seoul, Busan, Daegu, Daejeon and Gwangju - each with real-time train information, timetables and transfer details, according to its App Store listing. For paying the fare itself, see transport and payment.
