Internet in Réunion: everything you need to know
Réunion, a French overseas department in the Indian Ocean, has roughly 88% internet penetration and 4G/5G mobile coverage exceeding 95% of the population (source: ARCEP, 2024). Four carriers share the market: Orange Réunion (~35%), SFR Réunion (~25%), Free Réunion (~25%) and Zeop (~15%). Commercial 5G has been live since 2022 in Saint-Denis, Saint-Paul, Saint-Pierre.
- ●Excellent 4G/5G along the coast: Saint-Denis (Le Chaudron, La Bretagne, Le Barachois), Saint-Paul (Saint-Gilles-les-Bains, L'Ermitage), Saint-Leu, Saint-Pierre, Saint-Joseph, Saint-Benoît, Sainte-Suzanne, Saint-André. Good in accessible Hauts (Plaine-des-Cafres, Plaine-des-Palmistes, Le Tampon, La Plaine-des-Chicots) and around tourist sites (Cilaos, Hell-Bourg, Salazie). Patchier on Piton de la Fournaise (signal at Pas de Bellecombe, weak/none at Dolomieu crater and inside the enclos), Maïdo (4G at viewpoint, weak on Mafate trails), Mafate (isolated cirque: signal at hamlets La Nouvelle, Marla, Roche Plate, weak/none on GR R2/R3 trails).
- ●Average mobile speed ~80–150 Mbps download in Saint-Denis per Ookla (Q1 2025), peaking 500+ Mbps on 5G.
- ●Réunion is a French department: your mainland France plan covers Réunion at no extra cost (national "RLAH"). B&You, Sosh, Free, Sensation, Red by SFR plans work fully as in mainland France. An eSIM is only useful for non-French travellers (EU, UK, Switzerland, US) or to preserve your mainland plan.
- ●Great for Karos (local carpooling), Citalis (Saint-Denis bus), Car Jaune (regional coaches, app), Google Maps, offline IGN Rando (essential for GR R1/R2/R3 Mafate-Cilaos-Salazie), Météo France (reunion.meteofrance.com for volcano/cyclone conditions), Ti Coq (food delivery), Leboncoin, Air France for Mayotte/Madagascar hops.
