First Day in Korea — A 24-Hour Checklist
Your first day can eat itself if you do things in the wrong order. Follow the sequence and you go from airport to accommodation in under two hours.
The order that works
| Step | What | Where |
|---|---|---|
| 1 | Get online | Prepare before flying (or airport counter as last resort) |
| 2 | T-money card | Airport or city convenience store |
| 3 | Small amount of cash | Airport ATM or convenience store Global ATM |
| 4 | Get to the city | AREX or airport bus |
| 5 | Drop your bags | Storage if check-in is later |
| 6 | Install and set up apps | Ideally done before you fly |
Step 1 comes first for a reason. No data = no map, no translation, no transit app. Everything else depends on it.
1. Internet — eSIM vs. SIM vs. pocket WiFi
| eSIM | Physical SIM | Pocket WiFi | |
|---|---|---|---|
| Price range | 7 days from ~$10, unlimited from ~$20 | Airport ₩45,000 / online ₩25,000 (weekly) | ₩5,000–7,000/day (₩8,000–12,000 at airport counters) |
| Setup | Buy online, scan QR code | Swap physical card | Pick up and return a device |
| Works on arrival | ⭕ Instant | A few minutes to activate | Counter pickup required |
| Multiple users | ✕ (one per person) | ✕ | ⭕ (up to 5 devices) |
| Hassle factor | None | Card swap, risk of losing original SIM | Pickup, charging, return |
How to decide:
- Solo traveler → eSIM. As of 2026, for one person this is almost always cheaper and easier. No device rental fees.
- Two or more people → do the pocket WiFi math. At ₩5,000–7,000/day split across people, per-person cost drops. The catch: one person carries the device, so it falls apart if your group splits up.
- Older phone, no eSIM support → physical SIM. Check your device before leaving.
- Buying at the airport costs more. The same plan is routinely half the price online.
Prices reflect 2026 market ranges. Telecom promos shift constantly — compare at the time of purchase.
You might need a Korean phone number. Delivery apps and some reservation services require Korean phone verification. Data-only eSIMs do not include a number — if you plan to use those services, check whether your plan includes voice.
2. Transit card — T-money
Buy a physical T-money card at any convenience store and load it with cash. This is the most reliable method.
- Works on subways, buses, and taxis.
- Works at convenience stores for payments.
- High acceptance rate at unmanned luggage lockers — this alone is worth it.
- The mobile T-money app: foreign card top-up supports Mastercard, Amex, and UnionPay — not Visa. If Visa is your only card, plan on cash loading.
For an unlimited pass: the foreigner-only M-PASS runs ₩15,000 (1 day) to ₩64,500 (7 days), includes AREX All-stop trains, and requires cash purchase in won. The Seoul Climate Card was discontinued in September 2026 — ignore outdated guides. → Seoul Subway Guide
3. Cash — how much
Korea runs on cards, but you still need cash for a few things:
- Traditional markets, old restaurants
- Some older locker models
- Loading your T-money card
₩30,000–50,000 is plenty. Airport currency exchange desks give poor rates — change a small amount and use city ATMs or your card for the rest. Look for ATMs with a “Global ATM” sticker; not every machine takes foreign cards.

4. Getting into the city
Depends on your destination. Hongdae, Gongdeok, or Seoul Station → AREX. Gangnam or Itaewon → airport bus is the usual call. → Incheon Airport to Seoul
5. Drop your bags — the step everyone forgets
Morning arrival + 3 PM check-in means half a day with your suitcase. This is the single most common way a first day goes wrong.
If your accommodation accepts early bag drop, great. If not, store at a station locker or counter. Staying in Hongdae? Hongik Univ. Station has you covered. → Early Arrival, Late Departure Guide
6. Apps — install before you fly
| App | What it does | Why no substitute |
|---|---|---|
| Naver Map / KakaoMap | Navigation | Google Maps cannot navigate Korea properly |
| Papago | Translation | Korean menus, signs |
| Kakao T | Taxi hailing | Payment method registration may be restricted |
| T-money apps | Balance check | Optional |
The first row is the one that matters. Google Maps walking and driving directions are effectively broken in Korea due to map data regulations. Install Naver Map and set it to English before you leave home.
Sample timeline — morning arrival
| Time | Action |
|---|---|
| 09:00 | Land at Incheon, clear immigration |
| 09:40 | Baggage claim, customs |
| 09:50 | Activate eSIM (or pick up SIM / pocket WiFi) |
| 10:00 | Buy T-money at convenience store, load it; withdraw cash at ATM |
| 10:20 | Board AREX All-stop |
| 11:20 | Arrive at Hongik Univ. Station |
| 11:30 | Store bags |
| 12:00 | Lunch — your trip starts now |
| 15:00 | Retrieve bags, check in |
Mistakes people make
1. Buying a SIM card on impulse at the airport. You pay nearly double the online price. Prepare before you fly.
2. Relying on Google Maps. It cannot navigate Korea. Install Naver Map.
3. Buying single-journey tickets every ride instead of getting a T-money card. Ticket machines may reject foreign cards. The deposit refund process is annoying.
4. Not checking the check-in time. Most places are 3 PM. If you land in the morning, you need a bag plan.
5. Bringing zero cash. Markets and old restaurants will stop you cold.
Bottom line
The order: internet → T-money → cash → train → bags → go.
- Solo traveler: eSIM. Two or more: check pocket WiFi math.
- Buy your SIM or eSIM before you fly — it costs half as much.
- T-money loaded with cash is the safest setup.
- Naver Map, not Google Maps.
- Before check-in: drop your bags first, then start your day.
