For a seamless start to your Irish adventure, we recommend scanning your WorldESIM QR code and activating your plan before you even board your flight. This proactive approach ensures that the moment your plane touches down at Dublin Airport (DUB) or Shannon Airport (SNN), your data connection is immediately active. You can then instantly access maps, messaging, and transport apps without the hassle of searching for public Wi-Fi.
