Should I buy a SIM or eSIM at the airport?

Buying an eSIM online in advance is usually cheaper and works on landing; airport counters are convenient but slightly pricier.

What if my K-ETA is rejected?

You can apply for a short-term tourist visa at the Korean embassy instead, with full financial evidence and an itinerary.

Can I refund the remaining balance?

Yes, at convenience stores for a small fee, up to a capped amount.

K-ETA: what it is and how to apply

K-ETA is Korea's electronic travel authorisation for visa-waiver passport holders. Apply online at least 72 hours before departure; approvals remain valid for multiple years under current rules.

T-money card and using the subway

T-money is a rechargeable card for subways, buses and taxis across Korea. Buy it at convenience stores and stations, top up from 1,000 won, and tap both in and out to get distance-based fares and transfer discounts.

Incheon Airport to central Seoul

Three main options run from Incheon: the AREX train (43-60 minutes, cheapest and most punctual), a limousine bus (60-90 minutes but drops near hotels), and taxis, the most convenient but several times pricier.
