Getting to Sainte-Marie Island

Save the airport or ferry departure shown on your booking, your accommodation address and operator details before leaving Wi-Fi. Check current transport schedules and weather notices directly with your provider. Do not assume mobile signal aboard a boat or offshore, and keep your tickets available offline.

Beach and village days

Keep meeting points and return-route details offline before exploring. Supported local service depends on network, device and terrain, and may vary inside buildings or away from main towns. The eSIM does not include accommodation, transport or excursions.

Seasonal wildlife outings

If booking a whale-watching or other marine excursion, follow the licensed operator's season, conservation and safety guidance. Save the meeting point and emergency contact before departure. The eSIM cannot guarantee reception on the water or at remote coastal locations.

Install and troubleshoot
