Check your phone first
  • โœ“Your exact phone model supports the SIM or eSIM you plan to use.
  • โœ“Your phone is carrier-unlocked.
  • โœ“You can add an eSIM in Settings.

eSIM support can vary by exact model and country of purchase, so check your device settings or the makerโ€™s specifications before you buy.

Already bought an eSIM?

You usually do not need to visit a counter.

  1. 1Connect to the airport Wi-Fi.
  2. 2Open the eSIM installation information from the company that sold it.
  3. 3Add the eSIM, by scanning the QR code or entering the details.
  4. 4Select the Korea eSIM for Mobile Data.
  5. 5Turn on Data Roaming if your provider tells you to.
  6. 6Open a webpage or a map to test the connection.

Settings differ between providers, so follow the installation guide from the company that sold your eSIM first.

A counter can also help you buy an eSIM or set one up. You can collect the QR or setup details there, not a physical card.
