1. Why You Need a Korean Phone Number
While free Wi-Fi is common in Korea, a local phone number is essential for receiving verification texts (used in 90% of apps and services), using Korean taxi apps, and getting alerts. It also simplifies banking and delivery setups.
2. SIM, eSIM, or Carrier Plan?
- Prepaid SIM: Great for short stays. No ID needed for up to 90 days. Includes data, calling, and SMS.
- eSIM: For newer phones. Easier to activate online before arrival. Visit eSIM Korea.
- Carrier Postpaid Plan: Requires Alien Registration Card (ARC) for long-term stay. Good for students or residents.

At Incheon Airport, head to:
- KT Roaming Center (Terminal 1, 1F): Open 24/7

Alternatively, order online and pick up on arrival via sites like Klook or Trazy.
4. Best Carriers in Korea
- SK Telecom: Best nationwide coverage
- KT: Great for urban areas and 5G speeds
- LG U+: Budget-friendly prepaid plans
Many MVNOs (budget carriers) like Chingu Mobile offer cheaper rates tailored for foreigners.
