There are a few things that are much easier to sort out before your trip — or at least before you need them.
SIM cards, payments, maps, useful apps, basic rules, and the little things that can become annoying when you’re tired, jet-lagged, and standing in an airport.
We keep this section focused on the practical stuff worth knowing early.
Before you travel
Sort out entry documents, mobile data, power, apps, and seasonal packing while you still have time to compare options.
K-ETA and Korea e-Arrival Card
Check who needs K-ETA, who is exempt, when to submit the e-Arrival Card, and which official sites to use.
eSIM or physical SIM?
Compare setup, phone compatibility, data needs, calls, airport pickup, and the trade-offs that matter after landing.
Plugs, voltage, and adapters
Confirm Korea’s Type C/F plugs and 220V supply before packing chargers, grounded devices, or hair tools.
