CoreESIM advises scanning your eSIM QR code prior to departure for Indonesia, ideally while connected to a stable Wi-Fi network at your home location. This pre-activation ensures that your device's eSIM profile is provisioned and ready. Upon arrival at major entry points such as Soekarno-Hatta International Airport (CGK) in Jakarta or Ngurah Rai International Airport (DPS) in Bali, your CoreESIM service will automatically connect to our partner network, providing immediate data access without relying on public Wi-Fi or local SIM acquisition.
