Gyeongju eSIM
Gyeongju was a capital for a thousand years, and its tombs, temples and stone pagodas sit in a green city without a metro. A Korea eSIM keeps the bus routes and the train times online while you walk.

Before your Gyeongju trip
The KTX stops outside town
Singyeongju Station is on the KTX line, a bus or taxi ride from the sights. Keep the connection in your route app when you arrive.
The sights form a loop
The temple, the tombs and the old town spread across the city, and the buses between them run on timetables worth keeping online.
A day trip or a slow stop
Gyeongju works from Busan in a day, and from Seoul as a longer stop. The same Korea plan covers it; the card names the network.
A few things before you fly.
Is Gyeongju a day trip from Busan?
Yes. The train or bus takes about an hour, so the main sights fit into one day, with an early start.
Where does the train arrive?
Singyeongju Station, on the KTX line outside the centre, with buses and taxis into town.
Does the plan work outside the cities?
The same Korea plan covers the region; the card names the network it uses, which is worth checking against the route you take.
