We strongly recommend installing your eSIMFlyer plan before you even depart! Why wait for potentially spotty or congested airport Wi-Fi at Paris-CDG or Orly? By installing it at home or during a layover where you have stable internet, you ensure immediate connectivity the second your plane lands in France. Your plan's validity period only starts when it connects to a local network, so there's no downside to being prepared. Be airport-ready, not airport-waiting!
