The Mauritian SIM decision is unusually clean, because there is almost no coverage argument to have. Both operators a visitor is likely to meet sell the same package for the same money, both cover an island of 1,865 square kilometres to something like 99 percent of its population on 4G, and independent testers who run the two side by side around the coast road struggle to find a difference worth writing down. What is left is arithmetic and admin. A local card costs 1,500 rupees for a month of unlimited data and gives you a Mauritian number, which is excellent value if you are here for weeks and a substantial overpayment if you are here for six nights in a hotel with functioning WiFi. Below is what each operator charges in 2026, what the passport registration involves, and where the counters actually are.

Three Operators for 1.3 Million People
Mauritius supports three mobile networks on a resident population of roughly 1.3 million, which is a crowded market by any measure and explains why prices here are keen. my.t is the retail face of Mauritius Telecom, the former state monopoly, and its mobile arm still trades on paperwork as Cellplus. It carries close to 60 percent of the island's subscribers. Emtel arrived in 1989 as the first private cellular operator anywhere in sub-Saharan Africa and holds a little over 20 percent. Chili is the consumer brand of MTML, a subsidiary of the Indian state carrier MTNL, and takes most of what is left with pricing nobody else wants to match.
The regulator is the Information and Communication Technologies Authority, which oversees licensing and spectrum. Its footprint requirements have long since been satisfied on the main island: 3G and 4G reach essentially the entire resident population, my.t has pushed 5G toward 98 percent population coverage, and Emtel reports its own 5G somewhere between 80 and 90 percent of the island after a heavy spend in 2025. There is no equivalent here of the coverage gamble you take in a mountainous country. The towers are already where the people are, and on an island this compact the people are almost everywhere.
Why the choice matters less here than anywhere else
On most destination pages the network decides the trip. In Mauritius it decides almost nothing. Somebody who tested my.t and Emtel simultaneously across the whole island reported no distinction worth acting on, which matches what visitors say after a week of driving between Grand Baie and Souillac. Pick on price, on validity, and on which desk has the shorter queue.
my.t (Mauritius Telecom)
my.t is the incumbent and it behaves like one: the widest network, the deepest reach into Rodrigues and the far-flung Agalega islands, the most shops, and the least urgency about discounting. Its headline visitor product is the tourist SIM at 1,500 rupees, roughly 32 dollars at 2026 rates, which buys unlimited 5G data, unlimited local SMS, a 200 rupee call credit and 30 days of validity. That is the package sold at the airport desk and it is deliberately simple, with no tiers to compare and no allowance to watch.
my.t is also the operator that has leaned hardest into self-service for arrivals. It runs a digital kiosk near the baggage belts at the airport, open from seven in the morning until nine at night, and it will sell you an eSIM from a machine rather than a person if you would rather not queue. That is unusual, and it means a my.t line can be running before you have collected your bag.
When my.t is the right call
Take my.t if your trip is long, if it includes several nights on Rodrigues, or if you want the operator with marginally the best odds in the island's quietest corners. It is also the network behind Holafly, so if you want my.t coverage without the passport queue that is the eSIM route to it. For a straightforward week on the coast the extra reach is theoretical rather than useful.
Emtel, the Private Challenger
Emtel matched my.t on the tourist package rather than trying to undercut it, which tells you how comfortable both operators are with the current split. The visitor pack is also 1,500 rupees for 30 days of unlimited data, unlimited local SMS and 200 rupees of call credit, and the desk sits directly beside its rival in the arrivals hall. Staff activate the line while you wait and generally check it is working before you walk off.
Below the tourist package, Emtel's ordinary prepaid ladder is where the genuinely cheap Mauritian pricing lives. A basic starter SIM runs 100 rupees, a little over two dollars, and comes with 87 rupees of credit, 300 MB of data valid a week and a batch of local SMS. Data add-ons start as low as 12 rupees for a day pack, and you buy them by dialling a short code from the handset rather than going anywhere. That is a resident's pricing structure, but nothing stops a visitor using it if a full month of unlimited is more than the trip warrants.
Emtel is the network sitting underneath both Airalo and Nomad in Mauritius, which makes it the network most visitors end up on whether they realise it or not. Its 5G now covers the great majority of the island and its 4G is effectively universal on the coasts and the plateau.
Chili (MTML), the Cheap One
Chili is the outlier and the reason is structural: MTML is a smaller operator with a smaller network, so it buys share with price. Its visitor-friendly pack sits around 700 rupees, near 15 dollars, and carries 200 GB across 30 days. Set against the 1,500 rupee packs from the two large operators, that is less than half the money for an allowance no ordinary traveller will exhaust.
The catches are worth stating plainly. Chili sells no eSIM at all, so this is a physical card or nothing. Its coverage is described as good across the tourist areas and the plateau towns and noticeably thinner elsewhere, which matters if your itinerary involves the interior, the far south around Souillac, or a boat. And it does not have the same presence in the arrivals hall, so buying one usually means finding a shop in Port Louis, Curepipe or one of the plateau town malls after you have already landed.
Where Chili makes sense
Where it does not
Registering a Mauritian SIM to Your Passport
Every prepaid line in Mauritius is registered to an identity document. For a visitor that means handing over your passport at the counter, waiting while the assistant enters the details, and letting them activate the line before you leave. It is a routine transaction rather than an interrogation, and the airport desks process it constantly, but it is a step with consequences worth knowing about.
What actually happens at the desk
You choose the package, hand over your passport, the assistant scans or copies the details into the operator's system, inserts and activates the SIM, and normally confirms data is flowing before returning your phone. Budget five to ten minutes if there is nobody ahead of you and considerably longer behind a wide-body arrival from Europe or the Gulf.
The knock-on effects
Because the line is tied to a named individual, you cannot send one person from your party to collect four SIMs while everyone else waits with the luggage. Each traveller who wants their own number has to present their own passport. Nor can you buy one in advance for somebody arriving later. Registration is also the single step a travel eSIM removes outright, which is a bigger part of its appeal here than the price ever is.
Keep the passport accessible rather than buried in a case, and expect the assistant to want the biographic page rather than the entry stamp. Nothing about the process is unusual by regional standards, and Mauritius is far more organised about it than most.
The Mauritian Options Side by Side
Here is the whole market in one table, with 2026 rupee prices converted at roughly 46 to the dollar. Note how little separates the two large operators and how much separates all of them from the small travel eSIM tiers.
| Option | Price | What you get | Suits |
|---|---|---|---|
| my.t tourist pack | Rs 1,500 (about 32 USD) | Unlimited 5G data, unlimited local SMS, Rs 200 credit, 30 days | Long stays, Rodrigues, anyone wanting a local number |
| Emtel tourist pack | Rs 1,500 (about 32 USD) | Identical terms to my.t, sold from the next desk along | Same trips, whichever queue is shorter |
| Emtel starter SIM | Rs 100 (about 2 USD) | Rs 87 credit, 300 MB for a week, local SMS bundle | Light users happy to add day packs from Rs 12 |
| Chili pack | Rs 700 (about 15 USD) | 200 GB across 30 days | Budget-minded long stays on the coast and plateau |
| Small travel eSIM | 6 to 18 USD | 1GB to 5GB, live before you land, no ID needed | The standard week in a hotel with WiFi |
| Larger travel eSIM | 29 to 39 USD | 10GB to 20GB over 30 days | Self-drive itineraries and two-centre trips |
The interesting comparison is not the top two rows against each other, since they are the same product from different logos. It is the top rows against the bottom ones. A visitor who buys the 1,500 rupee unlimited pack for a seven-night stay in Belle Mare will typically leave having used three or four gigabytes of it, at four to five times the cost of an eSIM sized for that reality.
Where to Buy Once You Are on the Island
The airport is the obvious place and the busiest. Both my.t and Emtel keep desks in the arrivals hall, positioned next to each other so you can compare in the time it takes to walk past, and my.t adds an unstaffed kiosk near the baggage belts running seven in the morning to nine at night. The full airport picture, including the free WiFi and the transport out, is covered in the Mauritius Airport guide.
Away from the airport, both large operators have shops in the plateau towns and the malls that anchor them. Bagatelle in Moka, the shopping centres at Ebene, the retail streets of Curepipe and Quatre Bornes, and the Caudan Waterfront in the capital all carry at least one operator storefront. Grand Baie and Flic en Flac have outlets aimed squarely at visitors, and any small shop with a network logo taped in the window will sell you top-up vouchers even if it cannot register a new line.
Topping up without finding a shop again
Once your line exists, adding data is a short code away. Emtel customers dial a service code from the handset and pick a pack from the menu, and both operators run apps that do the same job over WiFi. Scratch-card vouchers are still sold in supermarkets, filling stations and the small shops in every village, which is genuinely useful on a Sunday in the south when nothing larger is open.
Which One Fits Your Trip Length
There is a fairly precise crossover point in Mauritius and it is worth finding before you commit. Below roughly two weeks the travel eSIM wins on every measure except the price per gigabyte, which is the measure that matters least when you are only using three or four gigabytes. Above roughly three weeks the local card wins on money so decisively that nothing else is worth weighing.
The middle fortnight is a judgement call and the deciding factor is usually whether you need a Mauritian number. Hire car companies ring you. Guesthouse owners on the south coast send an SMS rather than an email. Boat operators confirm a catamaran departure by text the night before. None of that is impossible with a data-only eSIM, because WhatsApp is universal here, but it is smoother with a local line.

Practical Mauritius Connectivity Notes
A few things about using mobile data on this island that the operator brochures do not cover.
Hotel WiFi does more work here than you expect. Mauritian hotels, from the big Belle Mare and Wolmar resorts down to guesthouses in Mahebourg, generally run connections good enough for video calls, and many all-inclusive properties advertise it as standard. If your day runs beach, lunch, pool, dinner, your mobile plan is a backup rather than a primary. This is the single biggest reason visitors here overbuy.
The exceptions are worth naming. A self-drive day across the south west will consume more than three resort days combined. The Black River Gorges trails drop out on the forest floor even though the viewpoints above are fine. A catamaran that pushes outside the reef loses service in a way a lagoon crossing does not. And Rodrigues, which is part of the same country and needs no new plan, has a thinner network and considerably less signage, so you will be leaning on the phone harder exactly where it works less well.
Currency and payment notes
Prices here are in Mauritian rupees, running near 46 to the US dollar and around 54 to the euro through 2026. Operator shops take cards without complaint. Buses do not: bus fares are cash to the conductor, typically 17 to 47 rupees depending on distance. Keep small notes for that and for the market stalls in the capital, which is covered in the Port Louis guide.
One number to keep in your head. A three to five gigabyte plan is the right size for the overwhelming majority of Mauritius holidays. If you cannot articulate a specific reason your trip is different, and hiring a car counts as a reason, buy small and top up if you are wrong. Topping up mid-trip is a thirty-second job in an app.
Frequently Asked Questions
Which Mauritian operator gives a visitor the best deal?
On headline price, Chili, which sells 200 GB over 30 days for around 700 rupees against the 1,500 rupees my.t and Emtel both charge for their unlimited tourist packs. On convenience, my.t or Emtel, because their desks are in the arrivals hall and Chili's are not. On coverage there is very little in it between the two large operators, and Chili gives up some ground once you leave the tourist strips. Most visitors should take whichever of the two big desks has the shorter queue and stop optimising.
What does it cost to get connected in Mauritius all in?
Around 1,500 rupees, near 32 dollars, if you buy the standard unlimited tourist pack from my.t or Emtel, with the SIM itself included in that figure. Around 700 rupees for the Chili equivalent. Around 100 rupees if you take a bare Emtel starter SIM and add data packs from 12 rupees a day as you go. A travel eSIM sized honestly for a week in a hotel lands between six and eighteen dollars, which is why the cheapest local option is not automatically the cheapest overall.
Can somebody else pick up a SIM for me while I collect the bags?
No. Mauritian prepaid lines are registered against an identity document, so each person wanting their own number has to present their own passport at the counter. There is no way to buy in bulk on behalf of a group or to collect one for a partner arriving on a later flight. Allow a few extra minutes per person if several of you want cards, and expect the desk to take the biographic page rather than any visa or entry stamp.
How do I add more data once I am out at a resort?
From your phone, without going anywhere. Emtel runs a short dial code that brings up a menu of data packs starting around 12 rupees for a day, and both large operators have apps that do the same over your hotel WiFi. Scratch vouchers are still on sale in supermarkets, filling stations and village shops if you would rather pay cash. On a travel eSIM the equivalent is a top-up inside the provider app, which works fine over the hotel connection.
Will a Mauritian SIM work if I take the boat or plane to Reunion?
No. Reunion is French territory and sits inside the European Union roaming arrangements, so it is an entirely separate billing world from Mauritius despite being under an hour away by air. A Mauritian SIM or a Mauritius-only eSIM stops at the water. If your trip pairs the two islands, buy a regional or multi-country plan that names both, or plan on picking up something separate once you land at Roland Garros.
