Absolutely. We recommend installing your WestESIM before you even board your flight. The plan will only activate once your device registers with a supported network in your destination country, such as France or the United States. This proactive approach ensures that you have immediate, high-speed internet access the moment your plane touches down, allowing you to navigate, communicate, and stay productive without any delay.
