Réunion eSIM

 Absolutely. Reliable data for Google Maps or Waze is essential to navigate the winding "road of 400 bends" to Cilaos or the coastal Route du Littoral. 

 Yes. Coverage is excellent along the western lagoon beaches like l'Ermitage and Boucan Canot, allowing you to post sunset photos instantly. 

 Yes. Saint-Pierre, the "capital of the south," has robust 4G+ infrastructure, making it a great base for remote work and video calls. 

 Most modern phones do, but you must check our specific list here: eSIM Compatible Devices to be 100% sure before purchasing. 

Yes, in most key areas. Réunion has a world-class French network. You will have a strong 4G/5G signal at the Piton de la Fournaise (volcano) viewpoint and in the main villages of the "Cirques" (like Cilaos). However, once you go deep into a remote hike, you will lose signal. It is perfect for navigation to the hikes, but not during the entire trek. 

 To give you the best speed (as you'd expect in France), our eSIM connects to Réunion’s premium Tier-1 networks, typically Orange Réunion or SFR Réunion. This ensures you get the fastest available 4G/LTE (and 5G) speeds, whether you are in Saint-Denis or at the beach in Saint-Gilles. 

Yes, 100%. Buying a physical "prepaid" SIM at Roland Garros Airport (RUN) requires finding the kiosk (which may be crowded), and going through a mandatory passport registration process as required by French law. Our eSIM is 100% digital, requires no ID registration, and can be installed before you fly, so you are connected the moment you land. 

It is complicated.

• For EU Citizens: Yes, "Roam Like at Home" (RLAH) technically applies. However, many non-French carriers (e.g., from Germany, Spain) enforce strict "Fair Use Policies" for remote territories and may cap or throttle your data.
• For UK/US Citizens: No! Post-Brexit UK plans and all US plans will charge you very high international "Rest of World" roaming fees.

A Cellesim eSIM guarantees a fixed price and high-speed data without "Fair Use" limits.
