Best eSIM for Réunion

Réunion is one of the most rewarding islands in the Indian Ocean to explore — the lunar landscape around Piton de la Fournaise, the cirques of Mafate, Cilaos and Salazie, the lagoon at L'Hermitage, and hairpin mountain roads where you'll lean on offline maps and live traffic updates more than you expect. It's also an unusual eSIM destination: a French overseas department that is legally part of the EU, sitting nearly 10,000 km from Paris. That means prices behave more like a mainland-European market than an African one — we checked live pricing across 96 providers we track for Réunion, and a realistic week-plus plan currently starts at $2.80 from 4S eSIM. Here's what actually holds up once you look past the headline numbers.

Quick-answer picks

• Cheapest way to get connected for a week: Textr eSIM's 1GB/7-day plan at $0.97.
• Best value for a two-week island trip: Yatelo's 5GB/30-day plan at $6.74 — enough headroom for maps, messaging and photo uploads without rationing.
• Best value for heavy use: Orbit Mobile's 20GB/30-day plan at $18.00.
• Cheapest unlimited week (with a daily cap): Roamix's unlimited 7-day plan at $5.35 — best for light, steady daily use rather than heavy streaming.
• Best-known global brand: Airalo, with a 5GB/30-day plan at $13.50.

Provider-by-provider breakdown

Textr eSIM has some of the lowest entry prices we track for Réunion right now: 1GB for 7 days at $0.97, 3GB stretched across 30 days at $2.72, and 10GB for a month at $7.28. If you mostly need WhatsApp, maps and the occasional search, it's hard to beat on price.

Yatelo is the strongest all-rounder for a typical Réunion holiday. Its 1GB/7-day starter costs $1.41, and the 5GB/30-day tier at $6.74 is the sweet spot for a 10–14 day trip where you're navigating mountain roads every day. It also sells local unlimited passes — 3 days at $11.22 — for a short stay where you don't want to think about data at all. Real discount code active:

15% off one purchase per customer (a new eSIM or a top-up) — the code can be used once per person, not on every order.

Orbit Mobile is the pick if you'll burn through data. Its 10GB/30-day plan is $10.50 and 20GB/30-day is $18.00 — both unusually close together, which makes the bigger tier the obvious buy if you're uploading hiking video or working remotely from a gîte. The 1GB/30-day plan at $3.50 is a cheap way to stay reachable on a long, light-use stay. Real discount code active:

Roamix has some of the cheapest unlimited pricing we found for Réunion: 7 days at $5.35 and a full 30 days at $18.40. The catch is the fair-usage policy: these plans give you a fixed amount of full-speed data each day and then drop to a much slower speed until midnight, so check the Daily cap and After cap columns in the live table before you buy. That's fine for maps and messaging, but frustrating for video calls or big photo backups. Its fixed 5GB/30-day plan at $6.05 is a solid fallback if you'd rather have full speed all month.

co:sim covers the short-stay end well: an unlimited 1-day pass at $0.99 (with a daily full-speed cap, like most cheap day passes) is a neat trick for a stopover from Mauritius, and its 10GB/30-day plan at $12.99 competes directly with the bigger brands on a month-long stay.

Saily sits in the middle of the market — 1GB/7 days at $3.99, 5GB/30 days at $12.99 — and is worth a look if you value an app with built-in security features and a well-known parent brand over the very lowest price. Real discount code active:

Airalo is the most recognised name in this comparison. You'll pay more than the specialists — 1GB for 3 days at $4.00, 5GB for 30 days at $13.50, 10GB for 30 days at $22.50 — but it has one of the most polished apps in the category and a huge install base, which matters if you'd rather use a tool you (or your travel companions) already know.

Why prices vary this much

Réunion is a small, isolated market, and eSIM providers buy wholesale access from carriers in very different ways. Some have a direct deal that treats Réunion like a local destination and price it close to mainland France; others route it through a wider regional or global package, which is why you'll see the same 5GB allowance priced several times apart in the live table below. A plan listed under "Réunion" that also covers 100+ countries is usually more expensive per gigabyte — you're paying for coverage you won't use on a single-island trip.

Unlimited plans are the other big spread. The cheapest unlimited passes almost always come with a daily high-speed threshold and a throttled speed after it; the pricier ones may be more generous or simply carry a bigger brand margin. Fixed-data plans are more predictable, and for most visitors 5GB over two weeks is plenty. If you're not sure how much data your trip really needs, our data usage guide is worth a read before defaulting to unlimited.

Which plan fits your trip

• A stopover or a long weekend: co:sim's unlimited day-pass at $0.99, or Textr's 1GB/7-day plan at $0.97.
• A classic 10–14 day road trip around the island: Yatelo's 5GB/30-day plan at $6.74 covers navigation, messaging and plenty of photo sharing.
• Hiking the cirques with lots of photo and video uploads: Orbit Mobile's 20GB/30-day plan at $18.00.
• Steady daily use over a longer stay: Roamix's unlimited 30-day plan at $18.40 — just remember the daily full-speed cap, and pick a big fixed-data plan instead if you upload a lot of video.
• A month or more, light use: Orbit Mobile's 1GB/30-day plan at $3.50 keeps you reachable for very little.

A few things worth knowing before you buy

Because Réunion is an outermost region of the EU, travellers with an EU mobile contract may find their home plan already covers the island under "roam like at home" rules — but some carriers treat the overseas departments differently in their fair-use terms, so check with yours before you land rather than assuming. For everyone else (UK, US, Australian and most other travellers), a dedicated eSIM is almost always far cheaper than home-carrier roaming here.

Coverage is strong along the coast, where most of the population and hotels are, and in the main towns inside the cirques. The high interior — the volcano, the Mafate hiking trails, which have no road access at all — can have patchy or no signal regardless of which eSIM you buy, because the underlying networks simply don't reach every valley. Download offline maps and your hiking routes before heading into the mountains, and don't rely on mobile data for safety on remote trails.

Install your eSIM at home over Wi-Fi so the QR code and setup are done before the long flight, but keep the line switched off until you land — many plans start their validity clock on first connection to a network, and some on installation, so read the activation rule for the plan you pick. If this is your first eSIM, our beginner's guide to how eSIMs work walks through installation and activation step by step, and our compatibility guide will tell you whether your phone supports one at all.

Most modern phones can keep your home SIM active for calls and texts while your data runs over the cheaper eSIM — useful if a bank or airline might text you a verification code during the trip. And if Réunion is one stop on a longer Indian Ocean itinerary with Mauritius or the Seychelles, price each island separately; our multi-country trip planner will show you whether a single plan genuinely covers your whole route.
