When is the optimal time to activate my CoreESIM QR code for Iceland travel?

For your trip to Iceland, CoreESIM advises scanning and installing your eSIM QR code well in advance of your departure, preferably while you are still in your home country. This pre-activation strategy ensures that your data service becomes active immediately upon your arrival at Keflavík International Airport (KEF). Having instant connectivity avoids the need to locate airport Wi-Fi and provides seamless access to navigation and communication from the moment you land.
