Noah landed at Incheon with two suitcases, a job offer and a list of 40 things to do, copied from five different blogs. By day three he had a bank account he couldn't use, a phone plan in his boss's name, and no appointment with immigration.

Everything in Korea depends on everything else. The order matters.

Do things in this order: phone data, ARC appointment, address, then the ARC unlocks banking, a proper phone plan and everything after. Here’s the sequence that saves the most backtracking.

Day 1Week 1Week 2–3Week 4+eSIM, T-moneyARC bookinglease, addressbank, phone
Each step unlocks the next.

Day 1: arrive and get connected

  • Prepaid eSIM or SIM with your passport, for maps and messages. See phone options.
  • T-money card from any convenience store for subway and buses.
  • Apps: KakaoTalk (everyone uses it), Naver Map or KakaoMap (Google Maps is limited in Korea), Papago for translation.

Week 1: start the paperwork

  • Book your ARC appointment on HiKorea. Slots can be weeks out, and you must apply within 90 days. Full guide: getting your ARC.
  • Ask HR for an employment certificate (재직증명서) and your contract. You’ll need them at the bank and immigration.
  • Check your payslip setup: salary, meal allowance and the four insurances. Run your figure through the salary calculator.

Weeks 2–3: housing

Week 4 and after: once the ARC arrives

  • Phone plan in your own name, spelled exactly as on your ARC.
  • Bank account, and ask to lift any transfer limits. See opening a bank account.
  • Health insurance: employees are covered from day one. Everyone else is enrolled after 6 months. See health insurance for foreigners.

Bank first, then phone, then ARC: the bank needs a phone in your name, and the phone carrier needs your ARC.

Prepaid data now, ARC booked in week one, then phone contract and bank once the card arrives.

Noah's redo: eSIM on day 1, ARC appointment booked on day 2 for week 4, lease signed in week 2 after a registry check.

ARC arrived in week 7. Phone plan and bank account were done the same afternoon.
