Mobile Networks in Réunion: What You Need to Know

Réunion's coastal areas have strong 5G and 4G coverage from Orange Réunion, SFR Réunion, and Free Réunion. The island's spectacular volcanic interior — the Cirque de Cilaos, Cirque de Mafate, and Piton de la Fournaise — has very limited or no mobile signal. Coastal towns from Saint-Denis to Saint-Pierre are well covered. Your HelloRoam eSIM connects through these three operators.

Best Time to Visit Réunion

Réunion's dry season from May to November is the best time for hiking and beach visits. The wet season from December to April brings cyclone risk and heavy rain in the east and highlands. The western coast around Saint-Gilles-les-Bains stays drier year-round. Volcano hikes to Piton de la Fournaise are best in the dry season. Always download offline maps before entering the cirques.
