Best eSIM for Mauritius: Plans and Prices Compared
August 5th, 2026
TL;DR
Keep On Roaming's cheapest plan for Mauritius is the Roam Like Home® Mauritius 1 GB 7 Days eSIM at £9.50. The lowest price per gigabyte in the range is the Mauritius 100 GB 30 Days plan at £142.50, which works out at about £1.43 per GB. For most holidays the middle of the range is the sensible pick: 10 GB over 30 days costs £22.50, or £2.25 per GB. If you would rather never look at a data counter, unlimited plans start at £11.50 for a single day, and every plan is on the Mauritius plans page.
What to look for in a travel eSIM for Mauritius
Start with coverage. An eSIM is only as good as the network behind it, so check which local operator the plan connects to and what speeds it supports. In Mauritius, Keep On Roaming plans connect to Mauritius Telecom, with 2G, 3G, 4G and 5G support.
Next, match the plan to your trip, not the other way round. A long weekend and a three-week honeymoon need very different amounts of data, so look for a provider with a proper spread of sizes and durations rather than one or two fixed options.
Top-ups matter more than most people expect. Holiday data habits are unpredictable (one rainy afternoon of video calls can empty a small plan), so choose an eSIM you can refill without buying and installing a whole new one. Keep On Roaming eSIMs can be topped up with more data from your account dashboard.
Finally, sort it out before you fly. You can install a Keep On Roaming eSIM at home via QR code, and it activates when you arrive in Mauritius and connect. That means you land with working data instead of hunting for airport Wi-Fi with your bags in one hand.
The Keep On Roaming plans for Mauritius
Here is the full range. All plans are data only, so your usual SIM, number, calls and texts keep working alongside the eSIM.

On a per-gigabyte basis, the fixed-data plans get steadily cheaper as they get bigger: the 3 GB plan works out at £5.00 per GB, the 10 GB at £2.25 per GB, the 20 GB at roughly £1.83 per GB, and the 100 GB at about £1.43 per GB, the lowest in the range. If you know you will stream, tether a laptop or share lots of video, the bigger fixed plans reward you for committing up front.
The unlimited plans work differently: you pay for days rather than gigabytes. They suit short, intense trips (a one-day layover, a three-day dive weekend) where you would rather not think about usage at all. For longer stays, compare the unlimited price against a large fixed plan of the same duration and be honest about how much data you actually use.
All of these plans run on Mauritius Telecom, with 2G, 3G, 4G and 5G supported.
Frequently asked questions
Will my phone work with an eSIM?
Most recent smartphones support eSIM, but two things must be true: your phone needs eSIM capability, and it must be unlocked (not tied to your home carrier). Check your phone's settings for an option to add an eSIM or data plan, and confirm with your carrier that the device is unlocked before you buy.
When should I install the eSIM?
Before you travel. Install it at home via the QR code while you have reliable Wi-Fi, and it will activate when you arrive in Mauritius and connect to the network. Installing early means no setup stress at the airport.
What happens if I run out of data?
You can top up an existing eSIM with more data from your account dashboard, without installing a new eSIM. If your plans change mid-trip, that is usually quicker than starting again with a fresh plan.
Will my phone number change?
No. These plans are data only, so your existing SIM, number, calls and texts keep working alongside the eSIM. Friends and family can still reach you on your usual number, and apps tied to your number carry on as normal.
Which network will I be on in Mauritius?
Keep On Roaming plans connect to Mauritius Telecom, which supports 2G, 3G, 4G and 5G.
When does my plan start counting down?
The eSIM activates when you arrive and connect, so installing it a few days before departure does not waste any of your validity period.
