You need three things: Naver Map, a transit card (T-money, or a Climate Card if you ride a lot in Seoul), and any translation app. Kakao T is your late-night backup for taxis. KORAIL+ (the new name for Korail Talk) or Klook only matter if you're taking the KTX. Google Maps can stay on your phone, but don't make it your main map in Korea.

Someone on r/koreatravel asked today which of these apps and cards they really need. A local already answered well: Naver Map, T-money and Papago as must-haves, Kakao T and Korail Talk as nice-to-haves, the Climate Card only for heavy subway days. Below is what I'd add to it, with the foreigner catches checked against official pages.

Why Naver Map instead of Google Maps?

In my recent experience, Google Maps misses a lot of detail in Korea, both for restaurants and for directions. I went to Google to check reviews of a restaurant that had been open for three months, and it wasn't on Google Maps at all. I don't think any other country has a map service as detailed as Naver.

The directions part is not just my impression. Google itself says its walking and driving directions aren't offered in Korea. In August 2026 Google said it plans to bring full turn-by-turn navigation to Korea, but there's no launch date yet.

Naver Map runs in English, Japanese, Korean and Simplified Chinese. It has walking directions and subway and bus routes, and Naver added English, Chinese and Japanese for visitor reviews and place filters in 2024. I compared the three map apps side by side in Naver Map vs Kakao Map vs Google Maps, and how locals actually pick restaurants in How Koreans find local restaurants.

Do you really need a T-money card?

Yes, or something that does the same job. You tap it at the subway gate and on the bus, and the same card pays for taxis and at convenience stores. Seoul's subway base fare is 1,550 won with a transit card, plus 100 won for every extra 5 km past 10 km.

The catch is topping up. Seoul City says the station machines take credit cards only for single-journey tickets, commuter passes and the Climate Card short-term pass. Topping up a prepaid card is cash. T-money's own English guide says the same thing in softer words: don't count on a foreign card, cash is the reliable way. So keep some won on you. More on that in Do you need cash for Seoul transport?

T-money or Climate Card: which one fits your plan?

T-money vs Climate Card really depends on how you plan your trip.

The Climate Card short-term pass is Seoul City's unlimited pass for the subway and Seoul buses, and it works inside Seoul only. Ride out to a city outside Seoul and you pay extra. It starts on the day you load it, so you can't load it in advance. You buy the 3,000 won card from the ticket machines at Line 1–8 stations, then load a pass. Since March 2026 the newer machines take foreign Visa and Mastercard cards, with a fee of about 3.7%.

Pass	Price	Subway rides to break even (pass only)	With the 3,000 won card
1 day	5,000 won	4	6
2 days	8,000 won	6	8
3 days	10,000 won	7	9
5 days	15,000 won	10	12
7 days	20,000 won	13	15

Calculated from the 1,550 won base fare. Longer rides cost more, so if you cross the city a lot you break even a bit sooner.

Your plan	Pick	Why
Walking around one or two neighborhoods a day, 2–3 rides	T-money	You won't reach the break-even count
A packed Seoul day with 6 or more rides	Climate Card, 1 day	Even with the card fee it pays off
Day trips outside Seoul	T-money	The Climate Card covers Seoul only. Get off at a station outside Seoul and staff charge the extra fare
Shinbundang Line, GTX, airport buses	T-money	Not covered by the Climate Card
iPhone and you want to pay with your phone	T-money in Apple Wallet	The mobile Climate Card is Android only

Do you need Papago, or will any translator do?

Translation apps are all good these days, so it doesn't have to be Papago. Any of them is fine.

Papago, Google Translate, DeepL: use whichever you already have, as long as it handles Korean.

If you do pick Papago, it's made by Naver. It translates the text in a photo, which is handy for menus, and it has offline text translation.

Do you need Kakao T?

Kakao T is for emergencies. In Korea, if public transport has stopped, you can just take a taxi. In Rome I couldn't get an Uber at all in the small hours, or even early in the morning, and it was a real problem.

Kakao T is the app most Koreans use to call a taxi, and it runs in English. Kakao also makes k.ride just for visitors: you log in with Google, Apple or email, pay with a foreign card, and chat with the driver through auto-translation. Uber works too, for licensed taxis. Taxis themselves take foreign cards, T-money and cash.

Korail Talk or Klook for KTX tickets?

Skip both if you aren't leaving Seoul by train. If you are, there are three ways:

Korail's English website (korail.com/global/eng). You can book as a non-member with an email and a password and pay with a foreign card. It's Korail's own site, in English.
KORAIL+, the app that used to be called Korail Talk. It was renamed in an August 2026 update, ahead of KTX and SRT merging under one name on Sept 1.
Klook. Since April 2026 it sells Korail tickets in real time through a partnership with Korail, and you board with a mobile voucher.

The whole booking walk-through, with the new two-months-ahead booking window, is in How to book KTX as a foreigner.

FAQ

Which map app should be my main one?

Naver Map. Google Maps has no turn-by-turn walking or driving directions in Korea, and new places can be missing.

Is the Climate Card worth it for tourists?

Only on heavy days inside Seoul, since it doesn't cover cities outside Seoul. A 1-day pass needs 6 subway rides to beat T-money once you count the 3,000 won card.

Do I need Kakao T if I have Uber?

Not strictly. Uber calls licensed taxis in Korea. Kakao T or k.ride is the backup if Uber can't find you a car.

Do I need Klook to book the KTX?

No. Korail's English site sells the same trains directly, and you can book as a non-member.

For topping up T-money, see our guide to paying cash and card on Seoul transport.

When Google adds full navigation

Google has said it plans full navigation for Korea. When that launches, the Naver-vs-Google advice could change, and I'll update this page. I'm also watching whether foreign contactless cards on Seoul transit make carrying cash for T-money less necessary.
