HelloRoam carries the only verified Reunion price in this comparison, across 5 plans on Orange 5G from $3.99 for 1 GB. Orange rings the island on Route Nationale 1 and 2 and holds the cirque approach roads, so one profile covers the whole drive. HelloRoam's 3 GB plan at $5.99 is $2.00 per GB, though the Reunion list stops at 10 GB with no 20 GB tier, and Airalo sells in 200 destinations.

Verdict: HelloRoam on Orange 5G, 1 GB at $3.99 and 3 GB at $5.99
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.
通信範囲の分析
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.
開通方法
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.
データ通信の活用のコツ
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.
ReunionのeSIMプラン料金
Reunion prices sit close to European rates. The 1 GB plan costs $3.99 over 7 days, and the 3 GB plan at $5.99 lands at $2.00 per GB. The 5 GB plan costs $12.99 over 30 days.
The 10 GB plan costs $21.49, holding a rate of $2.15 per GB. A single heavy day on the coastal road runs on the 2 GB day pass at $3.49. Verdict: HelloRoam sells 5 Reunion plans on Orange 5G from $3.99 for 1 GB, and its 3 GB plan at $5.99 gives $2.00 per GB.

Which network does eSIM use in Reunion?+
eSIM plans for Reunion connect to Orange, the island's carrier operating under French overseas territories regulations. Orange delivers European-standard coverage across the coastal ring road, all major towns, and most tourist sites. All 5 HelloRoam Reunion plans use that network, priced from $3.99 to $21.49.
Which network covers Piton de la Fournaise?+
Orange covers the main approach roads and the Pas de Bellecombe viewpoint on Piton de la Fournaise. Signal weakens on the crater floor and the remote lava field walks. The Bellecombe parking area at the trailhead holds a steady signal for pre-hike planning and post-hike uploads, and the 3 GB plan at $5.99 carries a week of them.
Can I use an eSIM in the Cirque de Mafate?+
Coverage in Cirque de Mafate is limited. The cirque is reachable only on foot or by helicopter, and signal is sparse in the lower villages. Orange gives intermittent coverage at higher elevations near Dos d'Ane. Download offline maps before you enter, and remember the 3 GB plan at $5.99 covers the rest of Reunion.
How do I activate an eSIM in Reunion?+
Install the QR code before departure. Orange registers the profile when you land at Roland Garros Airport in Saint-Denis, and you enable data roaming in settings. No airport SIM counter is involved. Any of the 5 plans, priced from $3.99 for 1 GB to $21.49 for 10 GB, installs the same way.
How much data do I need in Reunion?+
Travelers using Google Maps, WhatsApp, and Instagram need 400-700 MB per day. Hikers doing the Piton de la Fournaise circuit need minimal data on trail but benefit from connectivity at the trailhead. The 2 GB day pass at $3.49 is the simplest choice for one heavy day of uploads.
Does my phone support eSIM in Reunion?+
iPhone XS or newer, Pixel 3a or newer, and Galaxy S20 or newer support eSIM in Reunion. Your device must be carrier-unlocked. Phones purchased on contract are often SIM-locked. Check Settings under About or contact your home carrier before departure.
Is Reunion an expensive destination for mobile data?+
No. As a French overseas department, Reunion runs on EU-standard infrastructure and prices follow it. HelloRoam's 3 GB plan costs $5.99, which is $2.00 per GB, against its $2.20 median per GB across 185 destinations. The 10 GB plan at $21.49 covers a two-week stay on Reunion.
Can I use a Reunion eSIM to stay connected while driving the coastal road?+
Yes. Orange holds consistent coverage along the full Route Nationale coastal circuit from Saint-Denis to Saint-Pierre by both the east and west coasts. Navigation apps, music streaming and messaging work throughout the drive, including the cliff section on the west route. The 3 GB plan at $5.99 covers a week of that driving.
