eSIM for Réunion

Most visitors fly into Roland Garros Airport, which sits in Sainte-Marie, about 8 km east of the capital Saint-Denis. The airport has free wifi, so you can connect for the first short while. But airport wifi is slow and it stops working the moment you step outside.

This is why you set up your eSIM before you fly. Install it at home, then switch it on after you land. By the time you reach baggage claim you will have a real signal and can book a taxi, message family, or pull up a map without touching the airport network at all.

Your Réunion eSIM connects to the Orange network, which has the strongest coverage on the island. Once your phone finds Orange, you are online across Saint-Denis and the whole north coast right away.

If you are taking the Line ZE bus into Saint-Denis or grabbing a rental car, a small plan covers you fine for the first day. The 1 GB for 1 day plan is $0.76 and is plenty for maps, messages, and a few quick searches while you get your bearings.

The ring road around the coast links the main towns. You will pass Saint-Paul, the beach town of Saint-Gilles-les-Bains, and the southern hub of Saint-Pierre. Orange covers all of these well, so your maps and music keep working while you drive.

For a week of coastal travel, pick a plan that matches how you use your phone. The 3 GB for 15 days plan at $2.10 suits a light user who mostly checks maps and messages. If you stream music in the car or upload photos every night, the 5 GB for 30 days plan at $3.33 gives you more room.

The middle of the island is wild. The three Cirques, Cilaos, Salazie, and Mafate, are deep mountain bowls with steep roads and thick forest. Cilaos is reached by a famous road with around 400 bends. Mafate has no road at all and is reached on foot.

Signal in these areas is patchy and often drops out completely, especially deep in Mafate or on the high trails near Piton des Neiges. This is normal for any network, not just your eSIM. Download your offline maps and trail routes while you still have signal in town, then you can hike without worry.

If you drive up to Piton de la Fournaise, one of the most active volcanoes on the planet, expect the signal to fade as you climb toward the crater rim. The same goes for remote spots like the upper trails and the quiet south of the island.

Send anything important before you leave the last town with bars showing. A short data plan still helps here. The 1 GB for 7 days plan at $0.80 is a cheap backup if you only need light data for a few mountain day trips.

Light users who stick to maps, messaging, and the odd search do well on 1 GB to 3 GB. The 3 GB for 30 days plan at $2.24 is a smart pick for a relaxed two week trip with some downtime.

If you share lots of photos and videos, video call home, or work while you travel, go bigger. The 10 GB for 30 days plan at $5.99 covers heavy use for a longer stay. Compared to roaming with your home carrier, which can cost many times more per day, an eSIM is the cheaper and simpler way to stay online in Réunion.
