Is it possible to activate my WestESIM after crossing into Monaco?

For optimal convenience, we strongly recommend installing your WestESIM before you cross the border into Monaco. The transition from France (e.g., Cap-d'Ail or Beausoleil) to Monaco is often seamless, a simple street crossing, which can lead to an abrupt loss of your previous network signal. By activating your WestESIM beforehand, your device will automatically detect and connect to the local Monaco Telecom network, ensuring uninterrupted service from the moment you arrive.
