Yes, 100%. Buying a physical "KT" or "SKT" SIM at Incheon Airport is cheap but often involves long queues, especially after a big flight lands. It also requires a mandatory passport registration process. Our eSIM is 100% digital, requires no ID registration, and can be installed before you fly. You will be connected the moment you land, ready to use Kakao Maps or call an Uber/Kakao T.
