Busan eSIM
Busan packs beaches, a fish market and a hillside village into one metro line, with Seoul two and a half hours away on the KTX. You book, ride and order on a phone, so plan the data with the days.
Before your Busan trip
Gimhae Airport and the KTX
Gimhae International serves the city, and the KTX from Seoul reaches Busan Station in about two and a half hours. Install the eSIM before you travel so the first ride is online.
Coast and city on one plan
Haeundae, Gwangalli and the old town all sit on the metro. Keep the maps and the bookings live with the travel eSIM.
A base for Gyeongju
The old capital is about an hour away by train or bus, and the same Korea plan covers the trip. The card names the network.
A few things before you fly.
How do I travel from Seoul to Busan?
The KTX from Seoul Station reaches Busan Station in about two and a half hours; Gimhae handles the flights.
Does the plan cover the beaches?
Yes, the whole city and the coast are covered by the same Korea plan; the card names the network it uses.
Is one day enough in Busan?
A day covers the beach and the market, or the old town, but not both comfortably. Two days leave room for the coast and a Gyeongju trip.
