Wifi
(Lecture room)
(Incheon Airport) Free Airport WiFi is available throughout Incheon Airport, allowing you to stay connected even as you wait for your luggage.
(Transit to the City) Free WiFi, named "PublicFreeWifi," is provided on most buses and trains en route to the city. Please note that the WiFi service on buses may occasionally be out of service.
Public transportation:
- To use public transit, you need a transportation card (T-money card), which you can buy at a nearby convenience store.
- You can also charge the card at convenience stores, but the charge must be done with cash.
Credit cards are the most commonly used payment method, and most stores prefer them over cash. However, traditional markets and a few small shops may still prefer cash.
