Does CoreESIM streamline connectivity compared to Incheon (ICN) Airport SIM purchases, and what are the ID requirements?

CoreESIM significantly simplifies the process of obtaining mobile connectivity in South Korea compared to purchasing a physical SIM card at Incheon (ICN) or Busan (PUS) airports. Traditional local SIM acquisition, even for major carriers like KT or SKT, typically involves queues and a mandatory passport registration in compliance with Korean telecommunications law. CoreESIM is a digital product, eliminating the need for physical kiosks, wait times, or any form of ID verification, offering immediate activation upon arrival.
