All 5 of HelloRoam's Reunion plans roam on Orange, the island's 5G network and part of the French overseas territories infrastructure. As a French department, Reunion benefits from the same high-standard telecommunications investment as mainland France. Orange covers the full coastal road circuit, all major towns from Saint-Denis in the north to Saint-Pierre in the south, and tourist areas including Piton de la Fournaise and Saint-Gilles-les-Bains.
Coverage analysis
Orange covers Saint-Denis (the capital), Saint-Pierre, Saint-Paul, and the coastal strip around the island. The Route Nationale ring road maintains strong 4G throughout. Highland areas including the Piton de la Fournaise volcano crater rim and the Cirque de Cilaos have 4G along approach roads and at lookout points, with signal weakening on remote trails.
The Cirque de Mafate, accessible only by foot, has limited coverage in lower valleys.
Activation
Install your eSIM QR code before flying into Roland Garros International Airport (RUN) in Saint-Denis. Orange registers the profile when you land. No SIM shop or registration required.
Enable data roaming in your phone settings post-landing. iPhone XS or newer, Pixel 3a or newer, and Galaxy S20 or newer all support eSIM. Your device must be carrier-unlocked.
Data usage tips
Budget 400-600 MB per day for Google Maps navigation around the coastal road, WhatsApp messaging, and social media from beaches and viewpoints. Uploading drone footage or Instagram content from Piton de la Fournaise adds 1-2 GB per upload session. The 2 GB day pass at $3.49 suits hikers and road-trippers driving the ring road in a single day.
Offline maps for the cirque hiking trails are recommended as a backup.
