It is highly recommended to pre-install your CoreESIM for Paris prior to your departure. After purchasing, you will receive a QR code via email; simply scan this with your compatible smartphone to install the eSIM profile. This proactive measure ensures that upon landing at Charles de Gaulle (CDG) or Orly (ORY) airports, your device will immediately register with a local network, providing instant mobile data access for navigation, communication, and other essential services without any on-site activation delays.
