## Two arrival problems to solve first For a first trip, it is often worth sorting out luggage and mobile data before rushing into sightseeing. Both are easier when you know which services are airport-only, which continue into Seoul, and which need advance setup. ## SIM and eSIM VISITKOREA says Korea’s major mobile carriers offer both physical USIM and eSIM products. Physical SIM cards can be purchased at roaming centers in major international airports and at selected retailers; eSIMs can usually be bought online and activated by scanning a QR code on a compatible phone. Incheon Airport’s current facilities directory lists carrier roaming centers in both terminals, including some 24-hour locations. Exact counters and opening hours differ by terminal, so check the airport directory rather than assuming every carrier has the same location or schedule. ### Before buying - Confirm that your phone is unlocked and supports the SIM/eSIM type you plan to use. - Decide whether you need data only or a Korean phone number for calls/SMS. - If using eSIM, save the activation information somewhere you can access even if mobile data is not working yet. - Keep your passport available; telecom registration requirements can apply. ## Luggage storage and delivery Seoul Metro’s T-Luggage/T-Locker network offers storage and, on supported routes, same-day luggage delivery between selected subway locations and the airport. Incheon Airport’s official guide lists staffed T-Luggage points at Incheon Airport and major Seoul locations such as Seoul Station, Hongik University Station, Myeong-dong Station and Gimpo Airport Station. The service does **not** mean every subway locker can send a bag anywhere. The official guidance says at least one end of a delivery route may need to be a staffed T-Luggage location and service is limited to supported Seoul Metro lines/lockers. Incheon Airport also lists courier and baggage-related facilities, including 24-hour options in some terminal areas. For departure, separate services such as Easy Drop may allow eligible passengers and airlines to complete baggage drop away from the airport, but eligibility, closing times and routes are restricted. ## A useful arrival routine 1. Before landing, decide whether your phone will use roaming, physical SIM or eSIM. 2. At the airport, confirm the terminal-specific telecom counter if you need in-person setup. 3. If your hotel cannot take bags yet, compare airport storage with a Seoul T-Luggage/T-Locker location near your route. 4. For delivery rather than storage, check cutoff times and supported origin/destination pairs before handing over luggage. 5. Keep essential medicine, passport, electronics and valuables with you rather than sending them in checked or couriered luggage. ## Do not build the day around a service you have not confirmed Airport counters, locker capacity and delivery cutoff times can change. If a luggage service is essential to your itinerary, verify the exact location and operating window on the day rather than treating a map pin as a reservation.
