Is Réunion considered EU territory for roaming?

Réunion is a French overseas department and belongs to the European Union, but not every Italian operator automatically includes it in its 'Roam Like at Home' plans. Some leave it out altogether or add a surcharge. Before you go, it is worth checking with your operator or opting straight for a dedicated Datiovunque eSIM, so as to avoid nasty surprises on your bill.

Is there network coverage on the trails of the Piton de la Fournaise?

Inhabited areas and the main scenic roads enjoy excellent coverage. Around the volcano's summit and inside the Mafate cirque, which can be reached only on foot or by helicopter, the signal may be faint or missing. We recommend downloading offline maps before you set off and letting someone know your itinerary.

Will I need a plug adapter in Réunion?

No. Sockets in Réunion are Type C and E, which are the standard ones in Italy too. Voltage is 230V at 50Hz, exactly as in the rest of Europe, so all your chargers and devices can be plugged in as they are.

What is the best time to visit Réunion?

From May to November the weather is dry, which suits trekking, volcano excursions and diving. From December to April comes the rainy season, which is also the time for tropical cyclones, so outdoor activities can be restricted and some mountain roads are shut for a while.

Can I use the eSIM at sea and on boat trips?

You get a 4G signal along the coast and in the main harbours, Saint-Gilles-les-Bains among them. Out on the water it depends on how far you are from land: close to the island reception is generally good, but in open waters it is advisable not to rely on the mobile data connection.

How much does an eSIM for Réunion cost?

eSIM plans for Réunion start from €1.49. You pay once for the amount of data you choose — no subscription, no monthly fees and no hidden roaming charges. Plans with more data or longer validity cost more.

Can I keep my Italian number with the eSIM in Réunion?

Yes. Your Italian SIM and number stay active — the travel eSIM works alongside it as a data-only line. You stay reachable on WhatsApp, iMessage or Wi-Fi while you use the local network to browse. Traditional calls and SMS still go through your Italian number.

Should I activate the eSIM before or after I leave?

Install the eSIM at home, on Wi-Fi, before you leave. The data plan then activates automatically when you connect in Réunion. That way you are online as soon as you arrive, without looking for airport Wi-Fi or buying a local SIM.

Can I top up or renew the plan for Réunion?

Yes. When the data runs out or the validity expires, just buy a new plan — the eSIM profile already installed is kept and does not need to be installed again. You stay connected without interruption.

Can I share the connection (hotspot) in Réunion?

Yes. You can share the connection in Réunion through a personal hotspot with a computer, tablet or other devices. Shared data is deducted from your plan, so allow a few extra gigabytes if you expect to use the hotspot often.

How many GB do I need for Réunion?

For a normal trip, 1–3 GB a week is enough for maps, messages and occasional browsing. With social media and photo sharing allow about 5 GB; for streaming, video calls or a hotspot count on 10 GB or more. If the volume is not enough, you can buy an additional plan at any time.

Is the eSIM compatible with my phone?

The eSIM works with all compatible devices — including iPhone XS and later, Samsung Galaxy S20 and later, and Google Pixel 3 and later. The phone must also be free of operator locks (not blocked). You can check compatibility in the settings under "Mobile data", or by dialling *#06# to see whether an EID code is shown.

Réunion is a corner of France in the middle of the Indian Ocean, with active volcanoes, breathtaking natural cirques, black-sand beaches and a Creole cuisine that brings three continents together on one plate. Hiking up the Piton de la Fournaise or wandering the paths of the Mafate cirque, though, demands dependable GPS, up-to-date offline maps and the ability to call if anything unexpected happens in remote areas. Activate a Datiovunque eSIM before you leave Italy and your phone is online the moment you land in Saint-Denis. You will not need to hunt for a local SIM on an island where phone shops shut early and service is only in French.

Why an eSIM is essential in Réunion

Réunion is a French overseas department, so in principle you remain on European soil even though Rome is 9,000 km away. In practice, the roaming terms of Italian operators do not always count the island in their 'Roam Like at Home' plans, or they attach charges that are far from trivial. With a dedicated eSIM, the problem is avoided completely. The island's network, headed by Orange Réunion, delivers 4G/LTE to 95% of the territory, an impressive figure considering the mountainous terrain, with summits over 3,000 metres. Constant connectivity is essential not only for finding your way on the volcanic trails, but also for following updates from the Observatoire Volcanologique if the Piton de la Fournaise becomes active. The time difference with Rome is +3 hours in summer and +4 in winter, and a reliable connection from the first minute makes it much easier to receive messages from family in real time.
