Korea Pre-Trip Checklist: What to Sort Out 2–8 Weeks Before You Fly (2026)

Korea is one of the easiest countries in Asia to land in unprepared — and still, three things consistently bite travelers who wing it: entry paperwork, data, and money. Here's the checklist, ordered by deadline, with the honest version of each decision.

8+ weeks out

□ Check your entry requirements (K-ETA). Depending on your passport, you either need a K-ETA electronic travel authorization or are currently exempt — Korea has run rolling exemptions for dozens of countries, and the list changes. Check the official K-ETA site, not a blog (including this one). If you need it: apply at least 72 hours before departure; it's cheap and usually fast.

□ Book the high-demand stuff. DMZ tours, popular hanbok studios, and weekend KTX trains sell out. Everything else in Korea can be booked on 2 days' notice.

4–6 weeks out

□ Decide your data setup: eSIM, SIM, or pocket Wi-Fi. The short version:

• eSIM — right answer for most people with a 2018-or-newer phone. Install before you fly, land connected, skip the airport SIM counter queue entirely.
• Physical SIM at the airport — fine, but you'll queue after a long flight, and the counters price for captive customers.
• Pocket Wi-Fi — only makes sense for groups of 3+ sharing, or laptops-heavy work trips. One more battery to charge, one more thing to return.

Whichever you pick, get it before departure — the one moment you most need data (airport, jet-lagged, finding your transfer) is the moment you won't have it.

□ Sort your money plan. Korea is heavily card-friendly — foreign Visa/Mastercard works in nearly every restaurant, café, and shop in Seoul. You need cash for: markets, street food, some taxis outside Seoul, and small rural places. The practical setup:

• A prepaid travel card (e.g. WOWPASS — issued in Korea, doubles as a T-money transit card) or your own fee-free travel card.
• T-money transit card — non-negotiable for subway/bus. Buy at any convenience store, load with cash.
• Exchange a small amount only (₩100,000–₩200,000) — airport counters have the worst spreads; downtown offices and card top-ups beat them. (Wondering if a quoted rate or price is fair once you're there? That's what Price Guard does.)

□ Install the apps that actually work in Korea. Google Maps famously half-works (walking and transit routing are limited by mapping regulations). The local stack:

• Naver Map — navigation. English search is imperfect; save places in advance while you have Wi-Fi and patience.
• Papago — best-in-class Korean translation.
• GoKorean — the layer the others don't cover: point your camera at a menu, a price, a label, and it tells you what it is, whether it's safe for your diet, and whether the price is fair — the three questions translation alone can't answer. Set it up before you fly: pick your language and any dietary profile (halal, allergies) so it's ready at first use.
• Your airline app + offline copies of bookings.

□ Muslim travelers: do your restaurant homework now — see Is Korean Food Halal? for the dish-level rules and the certification tiers worth knowing before you build an itinerary.

48 hours out

• □ K-ETA / entry docs screenshot saved offline
• □ eSIM installed and toggled off (activate on landing)
• □ One day of cash + cards in separate places
• □ Hotel address saved in Korean (for taxi drivers) — copy it from your booking
• □ Apps installed, GoKorean dietary profile set
• □ Incheon → city transfer chosen: AREX express (₩13,000; online ₩11,500), all-stop train (₩5,000), bus, or taxi (fair range ₩55,000–₩90,000 — know it before someone quotes you $450)

The one-line version

Paperwork early, data before you fly, small cash + T-money on landing, local apps installed — and a way to check what's in front of you when the menu, the label, and the meter are all in Korean. Have a great trip.
