Mayotte eSIM for family visits across Grande-Terre and Petite-Terre
Choose Mayotte eSIM data for a family or work stay in Mamoudzou, an airport arrival on Petite-Terre or visits farther along Grande-Terre. Include the crossing and onward road journey in your planning, and keep addresses and receiving contacts saved before departure.
Mayotte's main islands are Grande-Terre and Petite-Terre. Mamoudzou is on Grande-Terre, while Dzaoudzi–Pamandzi International Airport is on Petite-Terre, so an airport arrival can be followed by a water crossing before the main road journey even begins. That geography matters for appointments and family pickups. A plan labelled France does not by itself establish Mayotte coverage, and nearby Comoros is a separate destination. Hilly roads, buildings, lagoon journeys and infrastructure disruption can all change whether mobile data is usable at a given moment.

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 Mayotte
Check eSIM support and the handset's unlocked status, then install the profile over Wi-Fi before travel. Save the airport pickup on Petite-Terre, any confirmed ferry instructions and the final address on Grande-Terre as separate stages. In Mayotte, choose Horizon for mobile data and enable its line's data roaming, leaving automatic switching to home data off. Installing the profile does not start the validity period; it starts when the eSIM first connects to a supported network in Mayotte. The Mayotte plan provides data only; exact reception depends on the location, local network conditions and device.

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 3 GB data allowance covers roughly 1,000 shared photos, 50 hours of social media and browsing, 8.8 hours of video calls, 38 hours of music streaming, or about 600 hours of maps and navigation. Messaging apps barely use data.

Important cities in Mayotte
Mamoudzou · City guide
Mamoudzou
Mamoudzou is Mayotte's administrative and commercial centre on Grande-Terre's eastern coast. A family home, office or appointment can still be some distance from the landing used by your crossing. Ask the receiving contact for the actual entrance and onward pickup arrangement, and retain them offline so that arrival does not depend on a live message after disembarkation.
Mamoudzou eSIM — set up before you flyPamandzi · City guide
Pamandzi
Pamandzi is on Petite-Terre, the island containing Mayotte's international airport. A booking for a Mamoudzou stay does not mean your flight arrives beside that accommodation. Confirm whether your host meets you at the airport or after the crossing, and keep the relevant names and instructions together before leaving your departure connection.
Pamandzi eSIM — set up before you flySouthern Grande-Terre · City guide
Southern Grande-Terre
Southern Grande-Terre includes communities around Bouéni, beyond the Mamoudzou arrival area. A local visit can require a final turn that is clearer in a host's written directions than in a broad map pin. Save the road route and receiving address before setting out, with current access checked locally; hills and quieter stretches can change reception along the way.

Budget for messages and the devices staying with you
A family visit may rely mostly on messages, directions and appointment documents. A work stay can add laptop transfers that use the allowance much more quickly. Horizon includes free personal hotspot sharing on a compatible phone during your Mayotte stay, and the shared devices draw from the same balance. Horizon fixed-data plans have no throttling. Choose validity for the entire stay, including arrival and departure crossings, while downloading large documents before travel. Check current official travel advice, transport information and the host's local guidance; the ability to buy data does not confirm normal transport or infrastructure operation.

Frequently asked questions
Does a France plan automatically include Mayotte?
No. Read the offer's actual destination list for Mayotte. Administrative ties do not establish what a commercial plan includes, and this Mayotte country plan does not add mainland France or Réunion to its coverage.
Why does an airport pickup for Mamoudzou involve another island?
Dzaoudzi–Pamandzi International Airport is on Petite-Terre, while Mamoudzou is on Grande-Terre. Confirm the airport pickup, water crossing and onward road transfer as separate stages, with current boarding arrangements checked before departure.
Will the data work throughout the crossing to Grande-Terre?
Do not rely on continuous reception over the water. Keep the receiving person's details, the arrival point and your accommodation address offline, and agree who meets you on which side rather than requiring a live location message during the crossing.
Does a Mayotte eSIM include Comoros?
No. Comoros is a separate destination and needs its own explicitly listed coverage. A shared regional geography does not extend a Mayotte country plan to Moroni or another Comorian island; confirm any journey and access arrangements independently.
Can a family device or work laptop share my Mayotte data?
For family devices or a work laptop in Mayotte, Horizon includes free personal hotspot sharing when the handset supports it. Count the connected devices' downloads and syncing in the same allowance as your phone, and keep essential appointment documents locally available when a connection is interrupted.
What should I prepare for a stay outside Mamoudzou?
Save the host's directions, the final address and the return plan before leaving the urban area. Review current official travel advice and local transport guidance, and confirm the approach to a Bouéni-area stay rather than assuming reception or road access from the map alone.
Will Horizon slow down my data?
No. Horizon fixed-data plans have no throttling. There is no daily limit that slows you down, so you can use your whole plan in one day if you need to. Your speed depends on the local network, your signal and how busy the network is. When your data allowance is used up, the plan stops rather than slowing down.
Can I get a refund if I already used some data?
Yes. 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.
