Is CoreESIM a more convenient option than purchasing a local SIM at Brunei (BWN) Airport, and what are the ID requirements?

CoreESIM offers a significantly more convenient method for obtaining mobile data in Brunei compared to acquiring a physical local SIM card at Brunei International Airport (BWN). Purchasing a local SIM from carriers like DST or Progresif typically involves locating a kiosk, waiting in line, and undergoing a mandatory passport registration process as required by Bruneian law. CoreESIM is a fully digital product, eliminating the need for physical interaction, queues, or ID submission, allowing for seamless pre-arrival activation and immediate connectivity.
