eSIM Providers for Mauritius (2026) — 5 Compared

We score each provider on five weighted dimensions for Mauritius: Pricing Tiers (20%) — per-GB cost and plan range; Coverage Breadth (20%) — carrier routing quality and 5G network reach via CHILI; Network Generation (20%) — which technologies the local network carries; App Features (20%) — installation flow and eSIM management; Support Channels (20%) — which channels exist and how long the refund window runs. HelloRoam, Airalo, Holafly, Saily, and Nomad are scored independently for each destination. The same provider can rank differently for Mauritius versus other countries depending on local carrier partnerships and pricing.

Airalo leads on coverage breadth for Mauritius with a 4.9/5 on the rubric coverage score and 200+ country network footprint. Coverage routes through CHILI. For Mauritius specifically, all five providers access the same 5G infrastructure, so urban coverage is comparable between them. Airalo's coverage advantage matters most for multi-country itineraries extending beyond Mauritius — Holafly, Saily, and Nomad score equally for single-country trips.

Our Mauritius matrix weighs five equal factors at 20% each: Coverage Breadth, Pricing Tiers, Network Generation, App Features, and Support Channels. Network Generation records the 5G technology in use. App Features evaluates how smooth installation and data tracking feel. Support Channels factors refund generosity (Holafly 180 days vs Airalo 14 days) and which channels are real-time. The composite score produces a 1-5 ranking per provider. Scores are Mauritius-specific since a provider scoring 4.5 here may score 3.8 in a neighboring country with different carrier routing.

Most travelers to Mauritius use 1-2GB per day on cellular. Maps, messaging, and social media consume 500MB-1GB daily. Streaming video pushes usage to 3-5GB per day. For a 7-day trip with good WiFi availability, a 5GB fixed plan covers light-to-moderate usage comfortably. Heavy users should consider Holafly's unlimited daily plan at $9.72/day. WiFi at hotels and cafes in Mauritius reduces cellular consumption by 30-60% depending on usage patterns.

Unlimited data in Mauritius costs $9.72/day through Holafly — $68.04 for a 7-day trip. A 5GB fixed plan costs $29.85. The breakeven point: if you use more than 6GB during your Mauritius trip, unlimited becomes cheaper per-GB. Remote workers streaming video or on daily video calls easily exceed 5GB per day, making unlimited the clear value play. Casual travelers using maps and messaging rarely need unlimited.

Install your eSIM 1-2 days before traveling to Mauritius. This gives you time to verify the profile installed correctly without wasting plan days. All five providers — HelloRoam, Airalo, Holafly, Saily, Nomad — start counting plan validity at first data use in Mauritius, not at QR scan time. On landing: open Settings, select your eSIM line, enable data roaming. Connection to 5G via CHILI happens within 60 seconds. If it does not connect, toggle airplane mode once.

Set your travel eSIM as the data line and keep your home SIM for calls and texts. On iPhone: Settings > Cellular > select the Mauritius eSIM line > Turn On This Line > set as Cellular Data. On Android: Settings > Network > SIM Manager > set eSIM as mobile data. Disable Data Roaming on your home SIM to prevent charges. Enable Data Roaming on the Mauritius eSIM only. All five providers — HelloRoam, Airalo, Holafly, Saily, Nomad — work in dual SIM mode.

Mauritius travel eSIMs run on 5G. 5G coverage here is limited. All five providers — HelloRoam, Airalo, Holafly, Saily, Nomad — access the same CHILI infrastructure, so the network is the same whichever one you buy. Peak-hour slowdowns affect all providers equally in dense urban areas. We publish no speed measurements, because we do not measure anyone's network.

Speed in Mauritius depends on CHILI's network infrastructure, not the eSIM provider. All five — HelloRoam, Airalo, Holafly, Saily, Nomad — deliver standard 5G service because they share the same towers. Think of it like five airlines boarding the same plane: the flight speed is identical regardless of which ticket you bought. Peak congestion and rural coverage gaps affect all providers equally in Mauritius. Network generation carries 20% of our composite score but rarely differentiates providers for any single country.

For Mauritius, the five providers split into clear use cases. Airalo scores highest for multi-country itineraries — 200+ destinations on a single account. Holafly scores highest on unlimited daily data if you stream or work remotely. Saily scores highest on privacy with built-in VPN protection (NordVPN infrastructure) at no extra cost. Nomad has the lowest per-GB price if cost is the deciding factor, starting from $8.10 for 1GB. Fixed data plans suit trips under 14 days; unlimited daily makes sense when you burn 5+ GB per day.

Efficiency depends on data consumption in Mauritius. Light users (maps, messaging): 1-3GB fixed plan from Nomad at the lowest entry price. Moderate users (social media, navigation, email): 5GB at $29.85 hits the sweet spot at $5.06/GB. Heavy users (streaming, video calls): Holafly unlimited daily at $9.72/day avoids per-GB math entirely. Fixed plans from all five providers access the same 5G network.

Mauritius eSIM prices range from $8.10 for 1GB (entry level) to $101.25 for 20GB (largest fixed plan). Unlimited daily data is available from $9.72/day. The lowest per-GB rate is $5.06 on the highest-volume fixed tier. All five providers — HelloRoam, Airalo, Holafly, Saily, Nomad — offer Mauritius plans with pricing set by their individual margin structures on the same CHILI carrier infrastructure.

Refund policies differ across the five providers for Mauritius plans. Holafly offers the most generous policy: 180 days to request a refund on unused plans. Saily and Nomad both offer 30-day refund windows for unused eSIM profiles. Airalo provides a 14-day refund period. All five require the plan to be unused — no data consumed — to qualify. If you have already activated and used data in Mauritius, refunds are at provider discretion.

Each device needs its own eSIM profile for Mauritius. A single purchase covers one device — you cannot share an eSIM between phone and iPad. Buy two plans or use your phone as a hotspot to share data with your iPad. Hotspot burns data 3-5x faster than single-device use. iPad models supporting eSIM: iPad Pro (all), iPad Air (3rd gen+), iPad mini (5th gen+), iPad (7th gen+). All five providers — HelloRoam, Airalo, Holafly, Saily, Nomad — work on compatible iPads for Mauritius.
