- Unlocked smartphone
- Valid passport (for physical SIM registration)

Ensure your phone is unlocked and supports the bands used in South Korea (FDD-LTE). For eSIM, check if your device supports eSIM profiles.
Purchase Your Plan
Buy a physical SIM at the airport or online, or purchase an eSIM from a provider like Holafly. You will receive a QR code or activation code.
Insert SIM or Install eSIM
For physical SIM, insert the card into your phone. For eSIM, go to Settings > Cellular > Add Cellular Plan and scan the QR code.
Activate and Test
Restart your phone if needed. Turn on mobile data and test your connection. For physical SIMs, registration may take a few minutes.
Practical Tips
💡 Use Naver Maps for Navigation
Google Maps is limited in South Korea. Download Naver Maps or Kakao Maps before your trip. They require internet but work offline with cached data.
💡 Keep Your Passport Handy
When buying a physical SIM, you must show your passport. Keep a photocopy or digital scan as backup.
💡 Consider a Data-Only Plan
Most tourists use messaging apps like KakaoTalk for calls. A data-only eSIM is often cheaper and sufficient.
