Absolutely! One of the primary benefits of using a Truly Roaming eSIM 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 on your device while you still have an internet connection at home. This means you'll be connected immediately upon landing at Incheon (ICN) or Gimpo (GMP), allowing you to access maps, book transport, and notify your team without any delay or hassle.
