Best eSIM providers for Mauritius: Quick look

Prices and plan details may vary depending on your location, currency and promotions. Prices may also be shown in different currencies depending on the provider. Always check the provider's website for the latest information before buying.

Airalo

Airalo’s Mauritius eSIM runs on the Emtel network and currently focuses on unlimited plans, with packages starting from $24 USD.¹ That makes it a straightforward option if you do not want to keep checking your remaining allowance during the trip.

The app is easy to navigate, and Airalo highlights top-up and auto-renew options if you need more time online. Hotspot use is not clearly highlighted on the Mauritius page, so that is worth checking before you buy if tethering matters to you. Support is available 24/7, including WhatsApp, which can help if you hit an issue after landing.

Good for: Travellers who want simple unlimited access and a familiar app with top-up support.

Holafly

Holafly’s Mauritius eSIM uses the my.t network and offers unlimited data, with prices starting from $10.50 USD on its official page.² If you are the sort of traveller who uses maps constantly, uploads photos, and streams on the move, that all-you-can-use structure can feel simpler than managing a fixed bundle.

One thing worth knowing is that unlimited does not always mean identical speeds in every situation. Holafly notes strong urban coverage, but says connection quality may be weaker in more remote areas. The app and email setup flow are straightforward, hotspot sharing is available up to 1 GB per day, and 24/7 support is included. Holafly also includes its Always On feature, which gives 1 GB of monthly backup data.

Good for: UK travellers who want unlimited data and do not want to think much about usage.

Nomad

Nomad’s Mauritius eSIM runs on Emtel and starts from $9 USD for a fixed-data plan.³ Unlike Airalo and Holafly, Nomad leans more towards travellers who want to match their spend to how much data they actually expect to use.

That can work well if your phone use is mostly practical, not heavy. Think Google Maps, restaurant searches, ride bookings, and messaging rather than regular streaming. Nomad supports hotspot use, offers add-on data, and lets you install now and activate later, as long as you start the plan within 60 days. Its app experience is one of its stronger points, especially if you like being able to manage everything in one place.

Good for: Travellers who want fixed-data options, hotspot support, and flexible activation timing.

Saily

Saily’s Mauritius eSIM starts from $7.49 USD and offers fixed-data plans through local partner networks.⁴ It is one of the more budget-friendly starting options in this comparison, but the bigger selling point is not just price. It is the added security layer in the app.

Saily includes tools such as ad blocking, web protection, and virtual location features, which may appeal if you often use public WiFi or want more control over your privacy while travelling. Hotspot use is allowed with no stated restrictions, automatic activation starts when you arrive, and the app warns you when you have used 80% of your data. Support is available 24/7 through live chat.

Good for: Travellers who want a smaller data plan with built-in privacy features and simple app controls.

How to choose the best eSIM for your Mauritius trip

If you are not sure which Mauritius travel eSIM to buy, the key question is how you actually use your phone on holiday. A cheaper plan is not better if it runs out halfway through your stay.

• Think about your trip length: A short beach break may only need a small or short plan, while a longer stay may suit unlimited or a larger bundle.
• Estimate your data habits: Maps, WhatsApp, and checking restaurant reviews use far less data than streaming, video calls, or uploading lots of content.
• Check hotspot rules: If you want to work from a laptop or share data with a travel partner, make sure tethering is allowed.
• Look at activation timing: Some plans start when you connect in Mauritius, while others may expire automatically if left unused too long.
• Check network coverage notes: Coverage is usually strongest around major towns and tourist areas, but can vary in more rural or coastal spots.
• Decide whether security matters to you: If you use public networks a lot, extra privacy tools may be worth paying for.

How to install and activate an eSIM for Mauritius travel

1. Check your device supports eSIM. Most newer iPhones, Samsung Galaxy phones, and Google Pixels do, but not every model does.
2. Make sure your phone is unlocked. If your device is tied to a UK network, it may not accept another mobile plan.
3. Buy your Mauritius eSIM online. You will normally receive a QR code or app instructions right after payment.
4. Install it while you still have stable WiFi. Doing this before you fly is usually easier than sorting it out at the airport.
5. Label the eSIM clearly in your settings. This helps you avoid confusion if you keep your UK line active too.
6. Choose the eSIM for mobile data. Keep your UK SIM for calls or texts if you want, but make sure mobile data goes through the travel eSIM.
7. Turn on data roaming for the eSIM. This often feels odd, but it is how many travel eSIMs connect to local partner networks.
8. Activate on arrival. In most cases, the plan starts when the eSIM connects to a supported network in Mauritius.

Why use an eSIM for travelling to Mauritius?

There is a reason more travellers now sort their mobile data before they leave home. An eSIM removes several small travel problems at once.

• You can get online soon after landing: That is useful when you need airport pickup details, maps, or hotel messages right away.
• You avoid swapping tiny SIM cards: No physical card means less chance of losing your UK SIM.
• You can keep your UK number active: Many phones support dual SIM, so your usual number can still receive important texts.
• You control the cost upfront: Prepaid eSIM plans make it easier to budget than relying on roaming.
• You can pick a plan that suits your trip: Light user, heavy user, short stay, longer stay, fixed data, unlimited, there is usually some choice.

FAQs about using an eSIM in Mauritius

Is my phone compatible with eSIM?

Many recent iPhone, Samsung Galaxy, and Google Pixel models support eSIM, but not every version does. Check your device settings or manufacturer details before you buy, especially if your phone came through a network contract.

Can I keep my original UK phone number?

Yes, usually. Many phones let you keep your UK SIM active for calls and texts while using your Mauritius eSIM for mobile data.

How much data do I need for my trip to Mauritius?

That depends on how you travel. If you mainly use maps, messaging, and browsing, a small plan may be enough, but if you stream, upload, or work online, you may want a larger bundle or unlimited data.

Can I make calls and send texts with an eSIM?

Many travel eSIMs are data-only, so standard calls and texts are not always included. You can still use apps like WhatsApp, FaceTime, and Messenger if you have data.

What if I run out of data in Mauritius?

That depends on your provider. Some let you top up the same eSIM, while others ask you to buy an add-on or new plan, so it is worth checking this before you travel.
