Traveler-compatibility checks for this destination are still pending. Local notes are useful, but phone, payment and signup eligibility are not yet sourced per service.
KakaoTalk is non-negotiable — friends, work, reservations, delivery updates and payments all run through it. Nothing else comes close.
The default for 95%+ of Koreans. Install before anything else; you'll be asked for a Kakao ID everywhere.
Minority use among some expats and interest groups; not how you reach a local.
Common for social/casual contact with younger Koreans and small businesses.
Rare locally — only useful for staying in touch with people back home.
Kakao T dominates and just dispatches licensed taxis (no private-driver Uber like the West). Street taxis are plentiful in Seoul too.
The default — taxi, black-car, and more. Register a card in-app; foreign cards work in recent versions but can be finicky.
Uber's Korea joint venture; the most foreigner-friendly for card payment and English. Solid #2.
Premium van/large-taxi bookings; useful for airport runs or groups.
All-electric premium fleet; smaller coverage than Kakao T.
Pay with a T-money IC card: buy at any convenience store, top up with cash, tap on/off buses and subway (transfer discounts within 30 min). Open-loop contactless bank-card tapping is rolling out but still limited — get a T-money card.
Metro-only app: real-time arrivals, first/last train, transfer and fastest-car tips; clean English mode.
Official T-money app for balance/records and Ttareungi bikes; account setup skews Korean.
Korea is nearly cashless — cards are taken almost everywhere. But Kakao Pay / Naver Pay / Samsung Pay mostly need a Korean bank account, so tourists lean on cards + a prepaid WOWPASS. Carry a little cash for traditional markets.
The dominant QR/P2P wallet locals use, tied to KakaoTalk — but needs a Korean bank account to set up.
Huge among locals (most carry Samsung phones); taps like a card and now supports T-money. Foreign-card registration is hit-or-miss.
The foreigner workaround: prepaid card you load with foreign currency at station kiosks; doubles as a T-money transit card.
Three-way market. Baemin is #1 overall; Coupang Eats is the easiest for foreigners (full English + fast). Baemin's 2026 update finally added English and an overseas-card checkout.
Korea's most-used delivery app with the widest restaurant selection; recently added English and foreign-card support.
Best pick for foreigners — English UI, single-order fast delivery, live tracking; bundled with Coupang membership.
The #3 option; has a web version and decent coupon deals.
Dawn delivery is the norm — order by ~11pm, groceries arrive before 7am. Coupang Rocket Fresh is the mass default; Kurly is the premium fresh specialist.
Cheapest and broadest same-day/dawn grocery; English support and free delivery on membership.
The dawn-delivery pioneer; premium fresh/organic and curated goods. Korean-first checkout.
Hypermarket delivery, often same-day from your nearest store.
Inside the Baemin app — 30-60 min convenience-store-style groceries and snacks.
Coupang is the Amazon of Korea with same/next-day Rocket delivery. Karrot (Daangn) is the everyday local secondhand marketplace and neighborhood board.
Korea has blazing 5G on SKT (best coverage), KT and LG U+. Global eSIMs work but often ride a single carrier — Airalo's Korea eSIM is KT and LTE-only. For a local number, grab a prepaid tourist SIM/eSIM from a carrier or at the airport.
Local carrier's own tourist prepaid eSIM with a real Korean number and 5G.
Seoul's public bike Ttareungi is cheap and everywhere. Heads-up: shared e-scooters legally require a car/motorcycle license and a helmet in Korea — enforcement happens.
Official Seoul city bike-share; very cheap daily/period passes, docks citywide.
Dockless shared e-bikes inside the Kakao T app; wide coverage.
Popular e-scooter/e-bike share; license required to unlock scooters.
e-scooter share in parts of Seoul; same license/helmet rules apply.
Mainly for longer stays: if you register for an Alien Registration Card (ARC) or need visa/immigration services, these are the official channels.
Official immigration portal — book visa/ARC/extension appointments (slots go fast).
Central e-government services and civil documents; Korean-first, needs local ID/login.
Government disaster/emergency alerts and nearest-hospital/shelter finder in English.
112 and 119 both offer live interpreter support for foreigners. For non-emergencies, 1330 (tourist) and 1345 (immigration) have multilingual staff.
Crime, danger, accidents. English/interpreter available; you can also text or send video.
Fire and all medical emergencies; connects to fire + ambulance, with interpreter service.
24/7 tourist help and live interpretation (English, Chinese, Japanese and more) by Korea Tourism Org.
Multilingual line for visa, ARC and foreigner-life questions.

Open-loop contactless bank-card tapping is rolling out but still limited — get a T-money card.
Open the map that works best locally and save your hotel or first stop.
The default map. Best transit routing, has English mode; some POIs only show under Korean search terms. Google Maps is crippled in Korea (no turn-by-turn driving, weak walking/transit) because the government bans exporting detailed map data. Use Naver or Kakao.
Check the local card, cash, and wallet reality before your first purchase.
