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.
