Réunion is French territory, so can I use a Europe eSIM there?

Réunion is a French overseas department (DOM), but it is not included in the EU roaming zone. A Europe-only eSIM plan often cannot be used for data in Réunion, so it is best to prepare a separate Réunion-specific or Indian Ocean regional plan.

Does the internet work well on Réunion's trekking routes?

At major natural landmarks such as the area around the Piton de la Fournaise volcano trekking routes and the Cirque caldera, a 4G/LTE signal is picked up most of the time. However, in extremely remote mountain backcountry sections the signal can weaken, so we recommend saving important maps and information offline in advance.

How do I get from Korea to Réunion?

No direct flights run from Incheon to Réunion. Routes via Dubai (Emirates), Paris (Air France) or Mauritius are commonly used. Expect a total travel time of around 17 to 22 hours depending on the stopover.

Will I need a power adapter in Réunion?

Réunion uses French-style type C/E sockets. The plugs on Korean electronic devices are usually compatible with type C, but it can vary by device, so check before departure. The voltage is 220V, the same as in Korea.

Which season suits a trip to Réunion?

Réunion's dry season runs from April to November. During this period the weather is clear and cool, good for enjoying trekking and water sports. December to March is the rainy season and cyclone season, with frequent heavy rain and strong winds, so keep that in mind when planning your trip.

Does eSIM work in Réunion?

Réunion supports eSIM, and plans start from ₩2,245. Install it with the QR code you receive after buying, then just turn on data roaming after you arrive and you are connected straight away. There is no need to swap your SIM.

Travel eSIM or carrier roaming: which is cheaper for a trip to Réunion?

For a short trip or light data use, a travel eSIM is usually cheaper. Unlimited roaming from Korean carriers costs about ₩11,000–₩15,000 a day, but with an eSIM you can buy just the days of data you need in advance. For a short trip for one or two people, an eSIM has a big advantage; for a family or very heavy data use, compare carrier unlimited roaming too.

Which carrier network does a Réunion eSIM use?

In Réunion it connects automatically to local carrier networks such as Orange · SFR · Free Réunion (4G/LTE, 5G where supported). Population coverage is about 95%. It picks the network with the strongest signal automatically, so there is nothing to set up.

Can I keep using my Korean number while travelling in Réunion?

Yes. The eSIM works as a data-only second line, so your Korean SIM and number stay as they are. Use the Yeohaengyusim eSIM for data only, and keep receiving calls, texts and KakaoTalk on your Korean number.

Can I add to or extend my Réunion eSIM plan?

Yes. When you use up your data or the plan period ends, you can buy a new plan at any time. Keep using the eSIM profile you already installed; there is no need to install it again, so you carry on without interruption.

Can I use tethering (hotspot) in Réunion?

Yes. In Réunion you can share your eSIM data with other devices such as a laptop or tablet by tethering (hotspot). Shared data also comes out of your plan allowance, so if you tether a lot we recommend choosing a little more data.

Do I set up the eSIM before I leave or after I arrive?

We recommend installing it (registering the QR code) before you leave, while you have Wi-Fi. Data starts when you turn on data roaming after you arrive in Réunion. Just remember "set up before you leave, switch on when you arrive" and you can use the internet as soon as you land.

Why you need an eSIM in Réunion

Réunion is a French overseas territory with telecom infrastructure at a European level. Major carriers such as Orange, SFR and Free Mobile run 4G/LTE networks covering 95% of the whole island, so a stable connection is possible not only in town but also on mountain trekking routes and coastal roads. A dependable data connection is a big help especially when you check a live map app or weather information while trekking on the Piton de la Fournaise volcano, or when you post a photo straight to social media at natural landmarks like the Cirque caldera. To get a SIM card at the local airport or a supermarket, a language barrier and tiresome procedures await you, but with a Yeohaengyusim eSIM all it takes is installing it in advance with a single QR code before departure Korea. You don't need to swap out your existing SIM card either, so you can keep your Korean number and use local data in Réunion to your heart's content. Even if you arrive exhausted after a long connecting flight, there is no worry about the internet.
