Absolutely! One of the biggest advantages of using an eSIM like Cellesim for your Seoul trip is the ability to activate it pre-arrival. You'll receive a QR code via email; simply scan it to install the eSIM profile. This means you're connected immediately upon landing at Incheon (ICN) or Gimpo (GMP) airports, ready to navigate or call a taxi.
