Should we install our Triply eSIMs before we fly or at Paris CDG Airport?

We strongly recommend your entire group installs their Triply eSIMs before you even board your flight! Why? Because airport Wi-Fi, especially at busy hubs like Paris-Charles de Gaulle (CDG), can be slow, unreliable, and often requires registration. Installing at home means everyone can securely set up their eSIMs using a stable Wi-Fi connection. Your plan's validity only begins once it connects to a local network in France, so you'll all be instantly connected the moment you land, ready to navigate and share your arrival.
