CoreESIM advises scanning and installing your Ireland eSIM QR code before you depart for your trip, ideally while you are still at home. This proactive activation ensures that your data service is immediately operational upon your arrival at major entry points like Dublin Airport (DUB) or Cork Airport (ORK). Having instant connectivity eliminates the need to seek out airport Wi-Fi and allows for immediate navigation and communication.
