For seamless connectivity, CoreESIM recommends scanning your QR code and completing the eSIM installation while still in your home country, prior to departure. This pre-activation ensures that your data service is immediately operational upon arrival at V.C. Bird International Airport (ANU) in Antigua. This eliminates the need to seek out public Wi-Fi or manage connectivity issues during your initial travel phase, providing instant access to navigation and communication.
