Setting up life in Korea is not hard, but the order matters. Many services depend on each other — you need a phone number before most accounts, and a bank account before most subscriptions. Do things in the wrong order and you will make the same trip twice. Here is the sequence that works.
Day 1–2: phone number first
A Korean phone number is the key that opens everything else: banking, deliveries, memberships, even some cafe wifi. Long-term residents should get a SIM registered in their name (bring your passport and, once you have it, your residence card). Airport counters work for the first week, but a proper carrier or budget MVNO plan is cheaper for the long run.
Day 3–4: bank account and transit
With your phone number and ID, open a bank account — major banks have branches used to foreign customers, and some have English service desks. Ask for a check card (debit) at the same time; it works almost everywhere. Then pick up a T-money card at any convenience store for subways and buses. Charge it with cash and daily movement is solved.
Day 5–7: the four apps that matter
- Naver Map or Kakao Map — Google Maps has limited walking and driving directions in Korea; locals use these instead.
- KakaoTalk — the default messenger for everything from friends to restaurant reservations.
- Coupang or a delivery app — next-day essentials while you furnish your place.
- Papago — the translator that handles Korean best, including photos of documents.
The classic trap to avoid
Do not schedule anything that needs identity verification — apartment utilities transfers, memberships, secondhand marketplaces — before your phone number works, because Korean verification runs on SMS to a number registered in your name. That single dependency is behind most first-week frustration.
Phone, bank, transit, apps — four steps, one week, and the rest of settling in becomes errands instead of obstacles.
