How do foreigners usually get a Korean phone number when they first arrive?

Daniel Novak ·

I just arrived in Korea and I need a local phone number for banking, deliveries, and signing up for apps. What is the usual way for foreigners to get a Korean phone number at the beginning, and are there any documents or carrier options I should know about?

Getting a Korean phone number is one of the first things you should do after arriving. Here are your options:

Option 1: Prepaid SIM card (fastest)

  • Buy at the airport (Incheon has KT, SKT, LG U+ booths in the arrivals hall)
  • You need your passport. Some carriers also accept ARC.
  • Cost: around 30,000-55,000 won for 30 days with data
  • Chingu Mobile and Korea SIM are foreigner-friendly prepaid options
  • You can also buy at CU or GS25 convenience stores

Option 2: Postpaid plan with ARC (best long-term value)

  • Once you have your ARC (Alien Registration Card), visit any carrier store:
    • KT: Best coverage nationwide
    • SKT: Largest network, premium pricing
    • LG U+: Often cheapest, good coverage in cities
  • Monthly plans: 30,000-55,000 won for unlimited calls + 5-15GB data
  • Bring your passport + ARC + Korean bank account (for auto-pay)

Option 3: Budget MVNOs

  • Budget phones: Cheaper carriers using KT/SKT/LG networks
  • Tplus, Hello Mobile, KT M Mobile
  • Plans as low as 10,000-20,000 won per month
  • Sign up at their stores or online (may need Korean language help)

Important tips

  • A Korean phone number is essential for banking, Kakao, Naver, and delivery apps
  • If you don't have an ARC yet, prepaid is your only option
  • Keep your passport ready when signing up for anything
  • Ask about phone installment plans if you need a new phone. 24-36 month plans are standard.
  • Port your number for free if you switch carriers later
