Réunion eSIM for the coast, Cilaos and Mafate
Use a Réunion eSIM for data between a Saint-Denis arrival, a booked Saint-Gilles or Saint-Leu coast address, a Cilaos road stage and preparations for Mafate on foot. Compare the shown data and validity with the confirmed route, without inferring coverage from mainland France or another island.
If you arrive via Saint-Denis and stay in Saint-Gilles or Saint-Leu, save the booked hotel’s exact entrance and transfer. The approach to Cilaos continues via the west and Saint-Louis onto a winding road with tunnels, so save the route, lodging and current road information. Mafate is different again: the trailhead, overnight stay and return arrangement are separate, and the tourism authority directs walkers to current ONF trail-status information.
For this trip
Which eSIM suits a Réunion trip?
Choose enough data for coast navigation, organiser messages, internet calls and intended uploads, with validity spanning every booked day. Confirm Réunion by name in the selected product; it is included in Horizon’s current Africa regional package, but France, Mauritius or another island is not added by inference.
Horizon sells the plans presented on this page, so the page is not a neutral market comparison or ranking. Compare the current details of the available products before choosing.
Intended data use
Maps and messages are lighter than frequent uploads or shared laptop work.
Entire itinerary validity
Cover the coast, Cilaos and any Mafate overnight from first connection through departure day.
Réunion listed explicitly
Use the exact destination list rather than assuming France, Europe or a nearby island applies.
Refund policy
We always refund the full amount you paid when you request it, whether your eSIM is unused, partly used or fully used. There is no time limit for requesting a refund.

How eSIM works in Reunion
Install the eSIM over dependable Wi-Fi before travel and keep the QR code separately. Leave the line off until Réunion, then select Horizon for mobile data and enable data roaming on that line. For this Réunion product, the first successful connection to a supported network in Réunion starts the chosen validity period. Download route, road and trail details before leaving the coast.
Install your eSIM
Scan the QR or auto-install in the app — no physical SIM.
Land & connect
Data activates on first connection at your destination.
Size it to your trip
Pick the profile closest to your trip. The estimate assumes normal use — maps, messaging, photos, a short call home.
As a rule of thumb, a 3–4 day city break runs on about 1–3 GB, a one-week trip on 3–5 GB, a two-week multi-country tour on 8–12 GB, and working on the road takes about 1 GB a day, so 15 GB or more for two weeks.

In total, a 5 GB data allowance covers roughly 1,700 shared photos, 83 hours of social media and browsing, 15 hours of video calls, 63 hours of music streaming, or about 1000 hours of maps and navigation. Messaging apps barely use data.
Important cities in Reunion
Saint-Denis · City guide
Saint-Denis
Saint-Denis may be the first island address, while the booked stay is in Saint-Gilles or Saint-Leu on the west coast. Save the actual accommodation entrance and transfer or rental-car confirmation.
Saint-Denis eSIM — set up before you fly →Saint-Gilles and Saint-Leu · City guide
Saint-Gilles and Saint-Leu
Saint-Gilles and Saint-Leu are distinct west-coast areas, so use the town named in the reservation. Keep the entrance, host contact and any departure point for an interior day together.
Saint-Gilles and Saint-Leu eSIM — set up before you fly →Cilaos and Mafate · City guide
Cilaos and Mafate
Cilaos is reached by a winding road via Saint-Louis, so store the route, lodging and current road information without relying on a fixed driving time. If Mafate is booked, save its trailhead, overnight reservation, return arrangement and current ONF trail status before departure.
Cilaos and Mafate eSIM — set up before you fly →Why Horizon
Why choose an eSIM for Réunion?
A prepared eSIM provides one data line for arrival messages, coast navigation and changes before an interior stage. Every Horizon plan includes free hotspot use, and Horizon does not throttle it; the phone and connected devices share one allowance. The Réunion eSIM is data-only and includes no local number. A compatible dual-SIM phone can keep your home line active, but its provider may charge for calls, messages or roaming.

Frequently asked questions
Does a France or Europe eSIM automatically cover Réunion?
Not automatically. Réunion must be named in the product’s destination list. Réunion is one of the six destinations in Horizon’s current Africa regional package, but that fact does not add mainland France, Mauritius or any other island.
What should I save before travelling to Cilaos?
Save the route via Saint-Louis, the Cilaos lodging entrance and the host or driver contact. Check current road information before departure because a fixed journey time or an always-open road is not promised.
Can I drive to my accommodation in Mafate?
No. The tourism authority describes Mafate as having walking access, so the car destination and the overnight lodging are not the same point. Confirm the appropriate trailhead, lodging instructions and return plan with the organiser before setting out.
Will the plan guarantee reception on every trail?
No. A country listing does not promise service at every mountain or trail location. Download the relevant information, check current ONF trail status and follow the agreed trip preparations before departure.
Can I use hotspot without an extra Horizon fee?
Yes. Hotspot is free on every Horizon plan, and Horizon does not throttle hotspot use. Your phone and connected devices draw from the same plan allowance, so count a laptop or companion’s tasks when choosing data.
When does validity start, and is a local number included?
The first successful connection to a supported network in Réunion starts the selected validity; installation or a failed attempt does not. The eSIM is data-only and has no local number. On a compatible dual-SIM phone you may keep your home line, whose provider may charge for its use.
