Pick up a T-money card at any convenience store (CU / GS25 / 7-Eleven / Emart24) or at the airport. Top up with cash, then tap on subway, bus, taxi, even snacks at GS25. WOWPASS adds a Visa-Mastercard layer so you can use the same card at almost any store. load it with USD/EUR/JPY at the kiosk and it converts.
WOWPASS kiosks are at every major subway station and ICN airport.
Korean law restricts mapping data exports, so Google Maps has almost no walking routes or transit info inside Korea. Naver Map is the local standard. full English UI now, real-time bus arrivals, accurate subway, even indoor mall maps. Kakao Map is a fine backup.
Kakao T has a full English mode. Type your destination, tap "Hail," watch the car come. Pay in-app with a foreign card or pay cash at the meter. No phone calls, no awkward addresses, no surge.
For airport runs, the in-app "Black" tier gets you a premium sedan booked the same way as a regular ride.
Korea is the most-connected country on earth, but you still want your own data for Naver, Papago, and Kakao T the moment you step off the plane. Airalo and KT M Mobile sell eSIMs that activate before you fly. If you prefer physical, the SIM counters at ICN take 10 minutes.
Papago (Naver's translator) beats Google Translate on Korean by a wide margin. Point the camera at a menu. it overlays English in place. Voice mode lets you order conversationally. Save phrases for offline.
Google Lens works too if you already have it open. same trick, different app.
Apple Pay launched in Korea in 2023, Visa/Mastercard contactless is now standard, and WOWPASS gives you a tappable prepaid card without a Korean bank account. Cash is rarely needed except at small market stalls.
Olive Young, Lotte/Shinsegae department stores, and most large retailers process the ~10% VAT refund instantly at the register if you spend ₩15,000+. just show your passport. No airport queue, no envelope to mail.
Most popular Seoul restaurants don't take weekend walk-ins. Catch Table is the local Resy / OpenTable equivalent. English UI, instant booking, and the same slots locals use. Naver also has reservation built in.
Hotels often won't store after checkout, and station lockers fill up fast. T-Luggage and Bounce have partner shops/cafes across Seoul that hold bags hourly. perfect for a last-day shopping run before the flight.
The Korea Tourist Hotline is free, 24/7, and live-translates English / Japanese / Chinese / more. They'll call restaurants for you, route you when you're lost, help with lost items, and recommend on the fly. Just dial 1330. no app needed.
From outside Korea: +82-2-1330. Save it before you fly.
