What is an eSIM, and how does it work in Mauritius?
An eSIM (embedded SIM) is a digital SIM card built into your phone, tablet, or laptop. Instead of slotting in a physical card, you download a network profile from a provider, which connects you to a local mobile network. For Mauritius, that means you can buy a plan at home, install it in minutes, and arrive already online.
When you buy an eSIM plan the provider sends a QR code or an in-app install link. Scanning it loads the profile onto your device, and from then on the eSIM behaves just like a normal SIM for data. You can keep your usual SIM active at the same time, so your home number still works for calls and texts.
Is an eSIM better than a local SIM card in Mauritius?
For most travellers, yes. A local Emtel or my.t SIM means finding a shop, showing your passport, and setting it up, while a travel eSIM installs before you fly and activates the moment you land. You keep your home number on your normal SIM for calls and codes, and use the eSIM for data. For a week at the beach or a longer island stay, an eSIM is usually the faster and simpler option.
Mobile networks and coverage in Mauritius
Mauritius's main mobile networks are Emtel and my.t (Mauritius Telecom), with MTML as a smaller third option. Together they offer strong 4G and growing 5G across Port Louis, Grand Baie, Flic en Flac, and the main coastal resorts, easing off in the central highlands. Travel eSIMs connect through these local networks, so you get dependable data where most visitors go.
Ubigi connects to Mauritius's networks for fast, steady data across the island, while Saily runs on the same local infrastructure with simple, affordable plans. Coverage is excellent across the coastal towns and resorts, and reliable on day trips inland to Chamarel and Black River Gorges, though signal can dip in the remote highlands.

How to choose the right eSIM for Mauritius
A few quick checks make it easy to pick the right plan before you travel:
Check your data needs: For maps, messaging, and browsing a small plan is usually enough. For video calls, remote work, or streaming, choose a larger plan or Ubigi's unlimited data.
Match your trip length: A week at the beach suits a small bundle, while a longer stay or heavy use is better with a bigger plan or unlimited data.
Working remotely? If you are working from Mauritius, an unlimited or larger plan keeps video calls and uploads running without watching a data counter.
Verify device compatibility: Most recent iPhones, Google Pixels, and Samsung Galaxy phones support eSIM. Check under Settings, then Mobile Network, then Add eSIM.
Customer support and setup help
Both providers offer support to get you online quickly. Ubigi has an in-app help centre and email support, plus clear install guides for iOS and Android. Saily offers in-app support and a simple interface that is friendly for first-time users. Whichever you choose, install and test the eSIM before you fly so you land already connected.
How to set up your eSIM in Mauritius
Setting up your eSIM for Mauritius takes just a few minutes:
1. Check compatibility: Confirm your phone supports eSIM (most recent models do). Ubigi and Saily both list supported devices on their sites.
2. Choose your plan: Pick a data size and validity that matches your trip.
3. Install the eSIM: After purchase you receive a QR code or in-app link. Scan or tap to load the profile onto your device.
4. Activate on arrival: Turn on your eSIM line and enable data roaming when you land in Mauritius. Activation usually starts automatically.
5. Test your connection: Open a map or browser to confirm data is working. If not, restart your phone or toggle airplane mode.
