Detailed provider reviews for Mauritius

Airalo

Best overall for Mauritius

Airalo's Mauritius plans typically connect to my.t, the dominant operator with the strongest island-wide coverage. Activation at MRU airport is reliable. The per-gigabyte rate is mid-range but Mauritius wholesale pricing is just higher than mainland destinations across the board — even the cheapest options here cost more than equivalents in Thailand or Vietnam.

Pros
  • Runs on my.t — best island-wide coverage
  • Reliable activation at SIR airport
  • Good app for managing top-ups during longer stays
Cons
  • Mauritius wholesale rates push prices higher than other destinations
  • Not the cheapest option in this comparison

Yesim

Best value

Yesim's $1.50 1 GB plan is by far the cheapest option for Mauritius and enough for short trips where you'll mostly be using resort Wi-Fi. The 5 GB at $7.50 is the right plan for a typical week-long active trip with car rental and excursions. Network performance has been comparable to Airalo in my testing — same underlying my.t or Emtel infrastructure.

Pros
  • Cheapest plans for Mauritius by a wide margin
  • 5 GB at $7.50 is the standout deal
  • 10 GB option for extended villa stays
Cons
  • App less polished than Airalo's
  • Customer support response time variable

Saily

Privacy-focused option

Saily's NordVPN integration is useful in Mauritius mainly for accessing home streaming libraries (BBC, Hulu, regional Netflix) during downtime. The 5 GB at $11.99 is competitive with mid-tier options and the 30-day validity covers honeymoon-length trips. Connects to Emtel typically and runs cleanly across the main beach zones.

1 GB
$3.49 · 7 days

5 GB

Pros
  • Built-in VPN access via NordVPN
  • 30-day validity even on smaller plans
  • Useful for accessing home streaming content
Cons
  • More expensive per GB than Yesim
  • No 10 GB+ tier

Drimsim

For multi-island trips

If your trip combines Mauritius with Réunion, the Maldives, or Madagascar (uncommon but possible for divers and cruise passengers), Drimsim's single balance saves swapping eSIMs at each stop. At ~$4/GB it's expensive for Mauritius alone, but the cross-destination continuity has value if your itinerary is complex. For single-island visitors, fixed plans win.

Pay-as-you-go
~$4.00/GB
No expiry
Balance never expires
Pros
  • Single balance across Indian Ocean destinations
  • Credit doesn't expire between trips
  • Useful for divers doing multi-island liveaboards
Cons
  • Expensive for Mauritius-only stays
  • Less polished app than competitors

How much data do you need in Mauritius?

Mauritius is a beach-resort destination first and foremost, which usually means modest data needs — most of your day is in or near the ocean, not on your phone. Where it changes is if you're driving the island independently, hiking the Black River Gorges, or working remotely from a Tamarin or Grand Baie villa.

For a one-week beach trip with one or two day excursions, 3 GB is plenty. Two weeks combining beach time with the Le Morne hike, Chamarel waterfalls, Île aux Cerfs, and Port Louis exploring, plan on 5 GB. Working remotely from a long-term villa rental for a month, push to 10 GB.

Worth knowing: Mauritius has comparatively fast and reliable internet thanks to undersea cables connecting it to the rest of Africa. Streaming HD video and video calls work fine on mobile data on both my.t and Emtel networks — better than you might expect from an island this size.

Resort Wi-Fi varies wildly by property. The big chain resorts (LUX*, Constance, Beachcomber) have decent in-room Wi-Fi included; smaller boutique places sometimes have it only at the main lobby. An eSIM gives you reliable backup either way.

Network coverage in Mauritius

Mauritius is small enough — about 65 km north to south — that you'll have signal almost everywhere. my.t (Mauritius Telecom) is the dominant operator, with the largest network and best rural reach. Emtel is a strong second, particularly in the central plateau and around Curepipe. MTML is the third operator, smaller in scope.

Coverage is excellent across all the main beach zones: Belle Mare and Trou aux Biches in the northeast, Flic en Flac and Le Morne in the west, Blue Bay and Mahebourg in the southeast. The Black River Gorges National Park has signal at the main entry points and along the road but thins on the deeper hiking trails. Île aux Cerfs and Île aux Benitiers (offshore islands) have working coverage from the mainland towers.

Tips for using an eSIM in Mauritius

Mauritius drives on the left and rental cars are the standard way to explore. Google Maps works well for the main road network including the M1 motorway between the airport and the north. For inland trails and the Black River Gorges, download offline maps before driving out — the trail intersections aren't always well-marked on Google.

For ride-hailing in Port Louis and the main tourist areas, Yango and Heetch have started operating in Mauritius and work fine with travel eSIMs. Coverage is more limited than European cities but they're cheaper than hotel taxis for short trips.

Many Mauritian businesses including dive operators, catamaran charters, and small restaurants use WhatsApp for bookings and communication. Get your eSIM active before you start coordinating excursions or you'll be tied to resort Wi-Fi.

If you're hiking Le Morne Brabant (the iconic mountain at the southwest tip), download the trail map ahead. There's signal at the trailhead and partway up, but the summit area can be patchy depending on which side of the rock you're on.

Why an eSIM is the right choice for Mauritius

SIR Seewoosagur Ramgoolam International Airport (MRU) has my.t and Emtel kiosks selling tourist SIMs, but prices are visibly marked up over local rates and registration takes time. By the time you've cleared passport control after a long-haul flight from Europe or the Gulf, the last thing you want is to queue for a SIM card when there's a 90-minute drive to your resort waiting.

An eSIM activates before you land, works the moment you walk out of arrivals, and is usually cheaper per gigabyte than the airport tourist plans even before you factor in the time saved. For a small island with consistent network coverage, the convenience math is overwhelmingly in favor of an eSIM.

Frequently asked questions

my.t (Mauritius Telecom) is the dominant operator with the widest geographic coverage including the central plateau, the south coast, and the more remote western areas around Le Morne. Emtel is a strong second, particularly in Curepipe and around Port Louis. Either is fine for typical tourist routes — the island is small enough that coverage gaps are rare.
Almost. Mauritius is compact enough that 4G LTE reaches all the major beach zones, the airport area, Port Louis, and along the M1 motorway. The Black River Gorges National Park has 4G at the main viewpoints and trailheads but thins on the deeper hiking trails. The summit of Le Morne can be patchy. Pockets of weak signal exist in the central highlands but nothing problematic for normal tourist activity.
Yes for the islands close to the main shore — Île aux Cerfs (off the east coast), Île aux Benitiers (off the west), and the islands in Blue Bay all get signal from mainland towers. The more remote islands and the Cargados Carajos shoals are out of range. Standard catamaran day trips are fine for connectivity.
Yes, surprisingly so. Mauritius has good undersea cable connections and 4G speeds on my.t and Emtel are comparable to European urban networks for normal use. Video calls on Zoom, Teams, or WhatsApp work fine from most beach destinations and resort areas. For heavy work uploads consider supplementing with resort Wi-Fi.
Yango and Heetch have entered the Mauritian market and work in Port Louis and the main tourist coastal areas with travel eSIMs. Coverage is more limited than in larger countries — many routes you'll still arrange with hotel taxis or pre-booked transfers. For short city trips in Port Louis, ride-hailing is usually cheaper than hotel cars.
