Seoul eSIM
Seoul is subway, markets and long evenings, and almost everything is found, booked or ordered on a phone. Plan the data by the days you stay, and the same plan covers the city and the day trips around it.
Before your Seoul trip
Two airports
Incheon International takes most arrivals, with Gimpo for short-haul and domestic flights. Install the eSIM before you fly, and the airport rail and the first subway ride work on landing.
The subway is the map
Apps pick the fastest line and update live. Keep the travel eSIM on mobile data; on a dual-SIM phone your home line stays free for calls and messages.
Day trips by train
Gyeongju, Jeonju and the border tours leave from the city, and the same Korea plan covers them. The plan card names the network it uses.
A few things before you fly.
Which airport do I land at for Seoul?
Incheon International for most international flights, and Gimpo for short-haul and domestic ones. The airport rail links both to the city.
Does a Seoul eSIM work across Korea?
Yes. A Korea plan covers the whole country, including the day trips; the plan card names the network it uses.
Can I keep my usual phone number?
On a compatible dual-SIM phone you can keep your home line for calls and use the travel eSIM for data. Check your carrier’s roaming charges before you change any setting.
