Mauritius Route Matrix: eSIM Columns Leg by Leg (2026)

Heading to Mauritius for a long weekend? Light data use (maps and messaging) runs about 1.5GB over 3 days on my.t's 5G network, which the 3GB at $22.50 covers. A moderate user using social media and navigation needs 4 to 5GB, so go with the 5GB at $29.85. Heavy users streaming or video-calling need 10GB or more; buy the largest fixed plan available. For a typical weekend traveler, the 5GB at $29.85 fits most weekend travelers without overpaying for unused data.

Longer trips to Mauritius cost less per day because bigger plans spread the price across more days. 7 days: 20GB plan at $101.25 total ($14.46/day). 14 days: 20GB plan at $101.25 total ($7.23/day). 30 days: unlimited at $6.61/day (32% off base rate), with full speed for the first 2 GB each day. The 14-day bracket balances daily rate and flexibility for most travelers visiting Mauritius.

You can top up your Mauritius eSIM through any of the five provider apps while traveling. Airalo lets you buy additional data through the app in real time, and the top-up lands on the eSIM profile already installed. Unlimited plans are also sold by the day: the 1-day Mauritius plan in the plan table costs $9.72, with full speed for the first 2 GB each day. Saily and Nomad both support fixed-data top-ups with no reinstallation. A top-up of 1GB costs $8.10, the same as buying a new plan. Buying a larger plan upfront is cheaper per GB than topping up, but the option is always available if you underestimate your usage.

Yes, eSIMs work in Mauritius. The network section on this page lists the local operators for Mauritius; the list does not say which one a phone joins. Google Pixel 3 and later, iPhone XR and later, and Samsung Galaxy S21 and later all work. Download your eSIM profile before departure so you connect the moment your plane touches down in Mauritius.

No, unused data does not roll over. Once your Mauritius eSIM plan expires, any remaining gigabytes are lost. Buy a plan that matches your actual trip length, not a larger buffer. The 20 GB Mauritius plan at $101.25 lasts 30 days from activation; data left when it ends does not carry over. If you change plans before installing, HelloRoam refunds an unactivated eSIM for 180 days, the same window Holafly gives unused plans, against 14 days at Airalo.

Most travelers in Mauritius use 1 to 2GB per day for navigation, messaging, and social media. A 7-day trip needs 7 to 14GB; a 14-day trip needs 14 to 21GB. The 20GB plan at $101.25 fits a week-long trip.

The network section on this page lists the local operators for Mauritius; the list does not say which one a phone joins. This site holds no coverage map and runs no speed tests, so it grades no city or rural coverage. Check the network section before choosing a plan for off-the-beaten-path itineraries.

Your daily data cost in Mauritius shrinks when you commit to a longer plan. A 7-day stay fits the 20GB plan at $101.25 ($14.46/day). A 14-day stay fits the 20GB plan at $101.25 ($7.23/day). Buying one correctly-sized plan costs less than buying two smaller plans back-to-back.

The network section on this page lists the local operators for Mauritius; the list does not say which one a phone joins. 1 of the 2 operators on that list carry a 5G label. A 5G label on that list is a technology label, not a speed. For a full-country itinerary, check the operator list before finalizing your plan.

Fixed data plans fit trips under 7 days in Mauritius. At 1.5GB/day the 20GB plan at $101.25 covers a 7-day trip with data to spare. Unlimited for 7 days costs $59.88, with full speed for the first 2 GB each day, which is comparable to a fixed plan. Switch to unlimited if you stream video daily, work remotely, or use navigation continuously. A 14-day unlimited plan costs $108.86 ($7.78/day), with full speed for the first 2 GB each day.
