Practical Korea: K-ETA, T-money, Naver Map & Etiquette

Before you fly: K-ETA and entry

Many nationalities need a K-ETA (Korea Electronic Travel Authorization) before boarding, though some countries are currently exempt — always check your own nationality on the official site. Apply only at the official k-eta.go.kr, not lookalike agency sites that add a fee.

Do it a few days ahead rather than at the airport, and keep the approval handy on your phone.

Staying connected

A SIM or eSIM makes maps, translation and messaging work everywhere. You can buy one at the airport on arrival or set up an eSIM before you land. Public Wi-Fi is common but a data plan is what keeps navigation reliable while you are out.

Getting around: T-money and the right maps

A rechargeable T-money card covers subway, bus, most taxis and even convenience-store purchases. Grab one at the airport or any convenience store and top it up as you go; many Seoul subway gates now also accept foreign contactless cards.

Crucially, Google Maps barely works for walking and driving directions in Korea. Download Naver Map or Kakao Map — both have English — and you will navigate like a local. Every spot on this site links straight into Naver Map.

💡 The plain T-money card works the same as the pricey character editions — buy plain unless you want the souvenir.

Paying for things

Cards are accepted almost everywhere, including small shops and taxis, and contactless is normal. Still, keep a little cash for traditional markets, some street-food stalls and the occasional cash-only spot. ATMs marked “Global” accept foreign cards.

Food for every diet

Halal, vegan and allergy-aware eating is more doable than many visitors expect if you know where to look. Itaewon has certified halal restaurants, Buddhist temple food is naturally vegan, and convenience-store items label allergens. Filter restaurant picks by your needs rather than hoping to improvise on the day.

Timing and closures

Most palaces close on Tuesdays and most museums close on Mondays, so double-check before you build a “culture day.” Public holidays can also shift opening hours. A good itinerary routes around these automatically — but it is worth knowing so a marquee sight is not shut when you arrive.

Everyday etiquette

• Give and receive with two hands, especially with elders or staff.
• Keep phone calls quiet on the subway; it is noticeably calmer than many cities.
• Take your shoes off where you see a raised floor or a shoe rack — homes and some restaurants.
• Nobody expects perfection from visitors; a little effort earns a lot of warmth.
