How to Get a Korean Phone Number as a Foreigner in Korea

Overview of Getting a Korean Number

In Korea, all mobile numbers are registered under a national ID or Alien Registration Card (ARC). Foreigners can choose between prepaid and postpaid services, depending on the length of stay and visa type. Prepaid SIMs are easier for short-term visitors, while postpaid contracts are suitable for residents with long-term visas.

Documents and Requirements

  • Alien Registration Card (ARC)
  • Passport (for identity verification)
  • Korean address (for billing or registration)
  • Bank account or debit card (for postpaid plans)
⚠️ Note Some prepaid SIMs only activate after ARC issuance, so short-term visitors may need temporary travel SIMs.

SIM Card Options for Foreigners

There are three main carriers in Korea: SK Telecom, KT (Olleh), and LG U+. Each provides foreigner-friendly plans available at official stores or through online retailers like EG SIM and Chingu Mobile.

  • Prepaid SIM: Ideal for visitors or students; no credit check needed.
  • Postpaid Plan: Requires ARC and local bank account; offers stable service and data plans.
  • eSIM: Available at major telecom stores for supported smartphones.
💡 Tip You can also register a SIM through HiKorea or visit a nearby Government24 linked telecom shop.

Step-by-Step Process

  1. Prepare your ARC and passport.
  2. Visit a carrier store (KT, SKT, LG U+).
  3. Choose prepaid or postpaid plan based on your visa and stay length.
  4. Provide address and payment details for registration.
  5. Activate your SIM and confirm your new number via text or call.
💡 Tip If you’re new in Korea, you can buy an EG SIM at convenience stores like CU or GS25 for easy activation without language barriers.
