Réunion is a French overseas department in the Indian Ocean, governed as part of the French Republic and using the euro as its currency. Its mobile network is operated by four carriers: Orange Réunion, SFR Réunion, Free Réunion, and Telco OI. 4G covers approximately 98% of the coastal population and all major towns including Saint-Denis, Saint-Paul, Saint-Pierre, and Saint-Gilles-les-Bains. Because Réunion is part of France, some France-coverage eSIM plans may include Réunion — always verify before purchasing. The island's dramatic interior — the three Cirques of Cilaos, Mafate, and Salazie — has very limited signal, as does the upper rim of the Piton de la Fournaise volcano. Orange Réunion has the best overall network, with the widest coverage including parts of the Cirques.
A travel eSIM is the fastest way to get connected — no SIM shop, no roaming charges, and your home number stays active.

Best eSIM for Reunion by Traveler Type
Not sure which plan to pick? Here's what we recommend based on your travel style:
West coast beaches (Saint-Gilles, L'Hermitage, La Saline)
The entire west coast has excellent 4G coverage. Perfect for navigation, sharing photos, and staying in touch. A 3 to 5 GB plan for 7 to 10 days covers a beach holiday comfortably.
Piton de la Fournaise volcano
Coverage is solid on the lower approach roads but disappears on the high lava plateau (Plaine des Sables) and near the summit. Download Google Maps offline for the Route du Volcan and the Pas de Bellecombe trailhead before leaving Saint-Pierre.
Cirque de Cilaos and Cilaos town
Cilaos town has reasonable 4G (Orange). The road up from Saint-Louis has signal in most sections. High-altitude trails above the cirque lose coverage. A standard 5 GB plan for 10 days works for the accessible parts.
Cirque de Mafate (hiking only)
Mafate is accessible only by foot or helicopter — no reliable mobile data anywhere in the cirque. Download all maps, GPX tracks, and lodge information (îlets) offline before descending. Your eSIM will only be useful at your starting/ending trailhead.
Saint-Denis and north coast
Saint-Denis (the capital) has excellent 4G and early 5G from Orange. The north coast, Sainte-Suzanne, and Saint-André are all well covered. A 3 to 5 GB plan for a week covers urban exploring and day trips comfortably.
Mobile Networks & 4G/5G Coverage in Reunion
Reunion has 4 major mobile operators: Orange Réunion, SFR Réunion, Free Réunion, Telco OI. All offer nationwide 4G coverage, with 5G now available in major cities.
4G speeds in Réunion average 25 to 60 Mbps on the coastal ring — fast enough for HD video calls, navigation, and streaming. Saint-Denis, Saint-Paul, Le Port, Saint-Pierre, and the west coast beaches all have excellent 4G. The interior Cirques — Cilaos, Salazie, and Mafate — have patchy coverage; Mafate (accessible only on foot) has almost none. The road around the Piton de la Fournaise loses signal on the high lava plateau. Orange Réunion has started early 5G deployment in Saint-Denis and the coastal strip. Download offline maps for any Cirque hike — especially the Mafate Circuit — before leaving the coast.
Most travel eSIM providers use Orange Réunion or SFR Réunion infrastructure in Reunion — both consistently ranked among the best networks in the region. You'll get strong, reliable signal in all major tourist areas.
Tips for Using Your eSIM in Reunion
🗺️ Check your plan includes Réunion
Réunion is a French overseas territory, not mainland France — always verify your eSIM plan explicitly covers Réunion before buying.
- Some 'France' eSIM plans cover only metropolitan France
- Check the provider's coverage map or FAQ before purchase
- Plans from Airalo, Holafly and Ubigi specifically list Réunion as a covered territory

- Include the approach roads and all planned trailheads
- Mafate has zero connectivity — all logistics must be arranged before descending

The airport is well covered by Orange 4G — but activating your eSIM at home is still simpler.
- Free Wi-Fi is available in the terminal
- Your eSIM activates automatically on landing via Orange Réunion
- Keep your home SIM active for incoming calls from mainland contacts

Frequently Asked Questions about eSIM in Reunion
Does eSIM work in Reunion Island?
Yes — several international eSIM providers offer plans for Réunion, including Airalo, Holafly, Ubigi, and Saily. Always confirm the plan explicitly covers Réunion (some 'France' plans cover only metropolitan France). Coverage is excellent on the coastal ring and in all main towns, with limited to no signal in the interior Cirques.
Is Reunion covered by France eSIM plans?
It depends on the provider. Réunion is a French overseas department, but not all France eSIM plans automatically include it. Always check the provider's coverage page before purchasing. Some providers — including Holafly and Airalo — specifically list Réunion as a covered territory.
What network is best for Réunion Island?
Orange Réunion has the best overall network, with the widest coverage including parts of the Cirques and mountain areas. SFR Réunion is a strong alternative for coastal and urban travel. Most international travel eSIMs connect through Orange Réunion.
Is there 5G in Reunion Island?
5G is in early deployment in Réunion, primarily in Saint-Denis and parts of the coastal strip. For most tourist itineraries, you'll be using 4G LTE, which is fast and reliable on the coast. 5G is not available in the interior or mountain areas.
Can I use my eSIM hiking in the Cirques?
Partially. Cilaos and Salazie have patchy 4G (Orange) in the town centres and on lower approach trails. The Cirque de Mafate has almost no mobile coverage — it's accessible only on foot and has no roads or reliable signal. Download all maps and GPX tracks offline before entering any of the three Cirques.
How much data do I need for Reunion Island?
For a 10-day Réunion trip combining beach time and volcano/cirque hikes, 5 to 8 GB is usually sufficient. Coastal connectivity is excellent. The time spent in the Cirques or on the volcano uses no data — so your total consumption is lower than for a city-focused trip.
What is an eSIM?
An eSIM (embedded SIM) is a digital SIM card built into your smartphone. You install a travel data plan by scanning a QR code — in under 5 minutes. For a Réunion trip, this means activating your plan before departure so you connect automatically on landing at Roland Garros Airport.
What are the downsides of using an eSIM in Reunion?
The main considerations are: 1) Verify the plan covers Réunion specifically, not just France; 2) Interior Cirques and high-altitude areas have little to no signal — offline maps are mandatory; 3) Mafate cirque has zero connectivity; 4) Your phone must be carrier-unlocked and eSIM-compatible. For coastal and urban travel, connectivity is excellent.
