Best eSIM for Mauritius 2026: 13 Providers Compared

Mauritius is compact enough that my.t, Emtel and MTML reach nearly every beach and town, with 5G on the main networks; signal thins only in the mountain interior and out on the lagoon. Mauritius wraps lagoons, mountains and sugar-cane hills into one compact Indian Ocean island, from the beaches of Grand Baie and Belle Mare to the waterfalls of the Black River Gorges and the buzz of Port Louis. Getting around runs on good data for maps and messaging, and an eSIM is the cleanest way to get it: install before you fly, land at Sir Seewoosagur Ramgoolam International, and your phone connects the moment it finds a local network. This guide compares the best eSIM options for Mauritius, explains what my.t, Emtel and MTML deliver, and helps you pick the right plan.

Emtel or my.t: the nPerf 2025 result for Mauritius

nPerf's Mauritius barometer for calendar year 2025 ranks Emtel first, ahead of my.t, the mobile brand of Mauritius Telecom (nPerf barometer, 2025). Emtel averaged 140.62 Mbps on downloads and my.t 132.78 Mbps, both fast enough for video calls from a beach bar in Grand Baie. The third operator, MTML, sells its lines under the Chili brand.

On an island of this size, the two main networks cover the coast and the towns, and the difference between them is small for a visitor. The networks used by each Simsima Mauritius plan are listed in its details.

Buying a SIM at the airport: passport, hotel address and a photo

my.t and Emtel sell SIM cards to arriving travelers, and Mauritius requires every SIM to be registered at purchase, tourists included. The regulator, the ICT Authority, lists what a tourist must provide: passport details or another valid travel document and a proof of address in Mauritius, and the operator takes a color photograph to check against the passport (ICTA FAQ).

In practice, that means having your hotel booking ready at the counter in the arrivals hall at Sir Seewoosagur Ramgoolam International, and some time for the registration. A travel eSIM installed at home skips that step and is connected when you land. Compare its price with the tables below for your trip length.

Drawbacks in Mauritius: no +230 number, lagoon dead zones

• No +230 number: taxi drivers, boat operators and restaurants often arrange things by phone, so share your WhatsApp instead.
• Data only, with no local calls or SMS.
• Signal weakens on trails in Black River Gorges National Park, on Le Morne and on boat trips across the lagoon to the islets.
• If your resort Wi-Fi is good and you rarely leave it, a small plan is enough.
• Your phone must support eSIM and be carrier-unlocked, and hotspot sharing depends on the plan.

Mauritius eSIM prices: capped and unlimited

Mauritius has a competitive market with fast networks, and prices are reasonable. Simsima runs on the local networks with transparent prices. Here is how a light 1 GB pack compares across eSIM providers:

If you would rather not track your usage, Mauritius also has unlimited-data eSIMs, with speed reduced after a daily high-speed allowance until the next day. Here is how the unlimited plans compare:

Simsima's full Mauritius lineup runs from small packs up to larger monthly allowances on the local networks. For a beach week with daily social media and photos, 2 to 3 GB is comfortable, since resorts have Wi-Fi; heavier users or anyone tethering should look at 5 GB or more.

How to install your Mauritius eSIM

Installation takes a couple of minutes and is best done at home on Wi-Fi before you fly. The plan activates on its own when it connects to a local network on arrival, so the validity window does not start early.

1. Buy your Mauritius plan on Simsima and open the confirmation with your QR code
2. On your phone, go to Settings, then Mobile or Cellular Data, and choose Add eSIM
3. Scan the QR code or use the one-tap install link, then label the plan Mauritius
4. Keep your home line as default for calls and texts, and set the eSIM for data
5. Turn on data roaming for the eSIM line only, then land in Mauritius and go online

Ten days of beaches and hikes: how much data?

A common trip: a few days around Grand Baie in the north, a day trip to Île aux Cerfs from Trou d'Eau Douce, then the southwest for Le Morne, the Seven Colored Earths at Chamarel and a hike in Black River Gorges. Maps on every drive, WhatsApp with drivers and excursion operators, and daily photos come to about 3 to 6 GB.

A capped plan of 5 to 10 GB for 15 days covers it. Couples sharing a hotspot in a rental car, or anyone working remotely from a villa, should look at the unlimited plans, where speed is reduced after the daily quota until the next day.

Getting around Mauritius: Metro Express, buses and drivers

Most visitors rent a car or book a driver, but the Metro Express light rail links Port Louis with Rose-Hill, Quatre Bornes and Curepipe, and buses reach most coastal villages. Data helps in each case: checking bus times, sharing your location with a driver, or navigating the narrow roads of the central plateau.

• Google Maps: driving directions, with offline areas for the southwest and the mountains.
• WhatsApp: works normally in Mauritius and is how most drivers, guesthouses and excursion operators communicate.
• Your airline's app: many flights to Mauritius connect through Dubai, Paris or Johannesburg, and schedules change.

Mauritius with Réunion, Rodrigues or South Africa

Mauritius pairs well with its neighbors: Réunion is a short flight away, Rodrigues is a Mauritian island reached by plane, and many travelers connect through Johannesburg or combine the trip with the Seychelles. Réunion is French, so EU plans roam there at domestic prices, while Mauritius is outside that system.

For two countries, two country plans installed at home are simplest. For an Indian Ocean or southern Africa trip, check whether a regional plan lists every country you will visit.
