Traveling across this diverse island—from its volcanic peaks to its coral-fringed lagoons—requires seamless connectivity. Traditional roaming drains your budget, while finding a local plastic SIM wastes precious vacation time. An embedded SIM provides a modern, hassle-free solution.
Your eSIM is a digital profile activated with a simple QR code. Here’s how it enhances your journey:
Using your home carrier's data in Réunion can incur fees of $10-15 per day. A prepaid travel eSIM offers substantial savings, with plans often costing 80% less. You pay a clear, upfront price for 1GB, 5GB, or even unlimited data, with no bill surprises when you return from your Indian Ocean getaway.
From tourists capturing the sunrise at the volcano to digital nomads video-calling from a café in Saint-Leu, an eSIM provides reliable, high-speed internet. Business travelers appreciate the professional reliability for meetings in the capital, while adventurers value having maps and safety info in the island's rugged interior.
Understanding the connectivity landscape ensures you stay online from the coastal resorts to the mountain trails.
eSIM providers partner with leading local operators to offer excellent coverage where you need it most:
Coverage in the isolated cirques (Mafate, Cilaos, Salazie) can be patchy due to the mountainous terrain. If trekking deep into these areas, download offline maps in advance.
In cities and along the coastal highway, you'll typically experience fast 4G speeds, perfect for streaming, video calls, and real-time navigation. 5G is available in limited urban zones, offering ultra-fast downloads. In more rural locales, your device may switch to 3G, which is still sufficient for messaging and basic browsing.
Most Réunion eSIM plans fully support tethering. Share your connection with a laptop to work from your villa in Saint-Gilles or with a tablet to entertain the family during a long drive to the lava tunnels. Remember, hotspot use consumes data more quickly, so factor this into your plan choice.
Match your data allowance to your itinerary and online habits for a stress-free experience.
For a 3-5 day trip focused on relaxation or guided tours, a 1-3 GB plan is often ample. This covers:
A 5-10 GB plan suits a week of independent travel, allowing for more social media, light video streaming, and regular navigation. If you plan to use video calls for work or to connect with family back home, lean toward the higher end of this range.
Digital nomads, long-term visitors, or those working remotely should consider plans of 10GB to 20GB, or even unlimited data. Look for providers offering 30-day validity or easy top-up options to maintain connectivity throughout a month-long immersion in Creole culture and island life.

Your eSIM data works with all apps. Approximate hourly usage: Maps (5-10MB), Social Media (50-100MB), Web Browsing (30-60MB), Audio Streaming (70MB), Standard-Quality Video Calls (300-500MB). For local transport, consider apps like Kar'ouest or Kar'est for bus schedules.
Your private mobile data connection is more secure than public Wi-Fi networks. For online banking or accessing sensitive work documents, always use your eSIM connection. Adding a VPN provides an extra layer of encryption, especially useful if you're working with confidential information from a café terrace.
If your goal is to hike the Pas de Bellecombe, snorkel in the lagoon of L'Ermitage, and savor Creole cuisine, an eSIM removes connectivity stress. Land with a working phone, navigate to your guesthouse in Hell-Bourg, and share your journey in real-time.
For those blending work with the island lifestyle, reliable internet is non-negotiable. An eSIM ensures you can join video conferences from your apartment in Le Tampon, upload files from a coworking space in Saint-Pierre, and stay productive without hunting for weak café signals.
Efficiency is key for meetings in the ZAC du Chaudron business park or at the Port Réunion authority. Instant connectivity from the airport allows you to confirm appointments, access cloud documents, and use ride-hail services seamlessly, maximizing your professional time on the island.
How quickly does the eSIM activate in Réunion?
Activation is near-instantaneous. Once you scan the QR code, your phone connects to local networks like Orange Réunion or SFR within 2-5 minutes. You can do this before departure or after landing at the airport.
Can I use my regular WhatsApp number?
Absolutely. WhatsApp remains linked to your home number. Keep your physical SIM active for SMS verification if needed, while your eSIM provides the data for all messaging, calls, and media sharing within the app.
Is mobile hotspot/tethering allowed?
Yes, most plans permit you to share your data connection. This is ideal for working on a laptop from your balcony overlooking the Indian Ocean or connecting a tablet for entertainment.
Can I make local phone calls with an eSIM?
Most travel eSIMs for Réunion are data-only. For voice calls, use internet-based apps like WhatsApp, FaceTime, Skype, or Google Meet over your data connection.
What if I use all my data before my trip ends?
Many providers offer easy online top-ups. Alternatively, you can purchase a new eSIM plan. It's wise to estimate your needs generously if you'll be streaming or hotspotting frequently.
Can I have multiple eSIM profiles on my phone?
Yes. Modern phones can store several eSIM profiles. You could have one for Réunion and another for a subsequent trip to Mauritius or mainland France, switching between them as needed.
How long is the eSIM plan valid?
Validity periods vary, typically ranging from 7 days for short getaways to 30 days for extended exploration. Choose a plan that covers your entire stay, from your arrival in Saint-Denis to your departure from Saint-Pierre.
How do I check my phone's eSIM compatibility?
Consult your phone manufacturer's website. Generally, if your device is a globally-sold, unlocked model from 2019 or later, it likely supports eSIM. It must also support the primary 4G bands (like B3 and B20) used in Réunion.
Should I take out my home SIM card?
No. The recommended setup is dual-SIM: keep your physical SIM in the slot for calls/texts, and use the eSIM for data. This way, you receive important bank alerts or 2FA codes while enjoying cheap local data.
Which eSIM provider offers the best coverage in Réunion?
Providers like Airalo, Holafly, and Nomad have reliable agreements with island networks. Coverage is generally excellent in populated areas. For the best value, compare real-time prices and plan specifics on eSIM Card List.
