• All-stop stations in order: T2, T1, Cargo Terminal, Unseo, Yeongjong, Cheongna Intl City, Geomam, Gyeyang, Gimpo Airport, Magongnaru, Digital Media City, Hongik University, Gongdeok, Seoul Station.

When do limousine buses and taxis make sense?

VisitKorea says several limousine bus routes serve Seoul and that tickets must be bought before boarding. They suit hotels near a route's stop when you want to avoid changing transport.

• Limousine bus: check which route and stop is nearest your hotel before buying.
• Taxi: Incheon has standard, first-class (deluxe), large/jumbo and International taxis.
• International taxis offer foreign-language support and need advance booking.

How do you get from Gimpo Airport to Seoul?

From Gimpo Airport, AREX all-stop reaches Seoul Station in about 23 minutes, according to VisitKorea. Gimpo Airport Station is also on Subway Lines 5 and 9, the Gimpo Goldline and the Seohae Line.

Central Seoul is about an hour away by subway from Gimpo, which is handy if your flight lands there rather than at Incheon.

Should you buy a SIM at Incheon or use an eSIM on arrival?

At Terminal 1, KT, SK Telecom and LG U+ have roaming centers on 3F (departures) and 1F (arrivals), and each carrier has a 24-hour counter near Arrival Hall F on 1F, according to the airport's facility list.

• VisitKorea says airport roaming centers sell SIM cards and rent Wi-Fi eggs, and that eSIMs can be bought online.
• eSIMs are set up with a QR code, so check that your phone supports eSIM.
• If you choose a physical SIM, ask at the counter whether it works with your phone, and make sure you are online before you leave the arrivals hall so you can follow a map to your platform or bus stop.
• At T2, check airport signs and maps for the carrier counters.
• VisitKorea says free public Wi-Fi is available at airports and at subway and train stations.

Why does mobile data matter on the way into Seoul?

Having data from the moment you land lets you open a map, check your destination station and message your hotel straight away, which helps when choosing between AREX Express and all-stop. It also helps if a plan changes, for example when you need to look up another bus route or tell your hotel that your flight arrived late.

• Visit Jeju says Google Maps navigation does not work in South Korea, so use Naver Map or KakaoMap.
• Download offline maps before you fly in case signal is weak on B1.
