Pay-per-use cost audit
What happens to your bill in Mauritius without an international plan
One day in Mauritius without an international plan: typical phone use runs roughly 450 MB. At AT&T's $2.05/MB pay-per-use rate, that day costs $922. Breakdown: 1 hour of navigation ($102), 30 minutes of Zoom ($922), uploading 20 photos ($410), light social media. One day with a Mauritius eSIM on CHILI: roughly $1.16 when you spread the plan cost across your trip. AT&T's International Day Pass is $12/day and avoids pay-per-use entirely — but even that costs more than most eSIM plans cover for the same period. Source: AT&T rate card, June 2026.

Network coverage
Local carrier network data for Mauritius
One network, two prices. CHILI covers Mauritius. AT&T charges $10/day to roam on it. A travel eSIM charges $5.06/GB on the same network. Trace the data path: your phone, CHILI's tower, the internet. That path is identical for roaming and eSIM. Only the invoice at the end changes. CHILI operates sub-6 GHz 5G across Mauritius. AT&T and travel eSIMs both access the same frequency bands. Switching from roaming to eSIM does not change which bands your phone uses or what speeds you get. The price changes: from $10/day to $5.06/GB. Mauritius has limited 5G coverage. 5G trials Average download speeds reach 25 Mbps on CHILI's network — identical whether you connect through a carrier roaming pass or a travel eSIM.
Pricing breakdown
Mauritius data pricing: carrier vs eSIM
T-Mobile includes free international data in Mauritius, but the speed cap is 256 Kbps, not enough to stream a 30-second video. Their high-speed add-on costs $15/day, reaching $210 over 14 days. AT&T and Verizon charge $140 and $140 respectively. A 10GB eSIM on my.t: $50.60.
Each day AT&T connects you to my.t in Mauritius costs $10. Buy a 10GB eSIM plan at $50.60 and that same daily access drops to $3.61/day. Over 14 days, the difference is $89.40.
eSIM pricing for Mauritius: 1GB at $8.10 ($8.10/GB), 3GB at $22.50 ($7.50/GB), 5GB at $29.85 ($5.97/GB), 10GB at $58.50 ($5.85/GB), 20GB at $101.25 ($5.06/GB). AT&T's 14-day roaming bill is $140 regardless of data consumed. Unlimited eSIM data costs $136.08 for the same period, $3.92 less.
Trip cost breakdown
Mauritius data cost scenarios: short trip to long stay
Three common trip types to Mauritius and what each costs on AT&T vs a my.t eSIM:
Weekend city break (3 days, 2GB): AT&T $30 · eSIM $22.50 · saves $7.50 (25%) 2-week family vacation (14 days, 15GB): AT&T $140 · eSIM $101.25 · saves $38.75 (28%) 1-month digital nomad (30 days, 50GB): AT&T $300 · eSIM $253.05 · saves $46.95 (16%)
AT&T charges $10/day whether you use 50 MB or 5 GB that day. eSIM plans charge for a fixed data block purchased once. At no point in any of the three scenarios does carrier roaming cost less. Rates checked June 2026.
Airport options
Mauritius airport connectivity
Most international airports have SIM kiosks near arrivals. Prices, wait times, and registration rules vary by country. In Mauritius, expect to show your passport and wait 15-30 minutes at the counter. A 1GB eSIM at $8.10 skips that process entirely — install it before your flight and connect as soon as you land.
Data planning
Mauritius data plan sizing for 7-day visits
Most Mauritius travelers burn through 1.5 GB daily: maps, ride-hailing, and restaurant searches add up quickly. Budget 11GB for 7 days.
The 20GB plan at $101.25 gives you roughly 20 hours of video streaming, or 256 hours of social media browsing. AT&T charges $70 for the same 7 days on the same my.t network. For heavy data users, unlimited daily plans start at $9.72/day — still cheaper than any carrier roaming pass.
Connectivity
Public WiFi coverage in Mauritius
WiFi is available in cities across Mauritius, but coverage drops in rural areas. Hotel WiFi works for basic tasks. Streaming or video calls on public networks may lag. For anything time-sensitive, an eSIM on my.t is more consistent.
Plan your data
Mauritius connectivity: planning your GB budget
AT&T's International Day Pass in Mauritius bundles voice, SMS, and data into $10/day. Most travelers use messaging apps for calls and need only a data plan. A data-only 20GB eSIM on my.t costs $101.25 for 10 days — -1% less than AT&T's bundled rate.
Mauritius has one mobile operator: CHILI. US carriers pay CHILI for roaming access and pass that cost to you at $10/day. An eSIM connects to CHILI directly at $5.06/GB — no carrier markup.
Airport SIM counters at Sir Seewoosagur Ramgoolam (MRU) charge $5-10 for 5-10GB / 28 days — still more than a 20GB eSIM at $101.25. Mauritius mobile networks deliver an average 25 Mbps download speed — the same whether you roam on AT&T or connect through a travel eSIM. WiFi in Mauritius is available in hotels and cafes. An eSIM fills the gaps at $5.06/GB instead of AT&T's $10/day roaming charge.
Quick reference
Mauritius Travel Essentials
999/112
999 and 112 both connect to emergency services in Mauritius. 112 is the EU-standard number and works from any mobile phone, including roaming and eSIM devices, even without a registered local number. Save both before your trip.
Type C/G
Mauritius uses Type C outlets (European two round-prong). US plugs require a Type C adapter. Check that your phone and laptop chargers show 100-240V input — most modern chargers are compatible.
MUT (UTC+4)
MUR (Rs)
Cards are accepted at hotels, tourist-facing shops, and chain restaurants in Mauritius. Local markets, small vendors, and rural businesses prefer cash. Withdraw MUR at an ATM on arrival — airport ATMs have the same rates as city ATMs.
Good to know
One operator, CHILI, runs all mobile coverage in Mauritius. Carrier roaming and eSIM plans use the same infrastructure — comparing costs is the only meaningful variable.
Quick tip
Mauritius uses MUR (Rs). eSIM plans charge in USD at the time of purchase — you lock in the cost before travel and avoid in-country exchange rate moves.
Step by step
Mauritius eSIM setup from purchase to active connection
- On iPhone: go to Settings > Cellular > Add eSIM to confirm your device is unlocked and eSIM-capable before buying a Mauritius plan
- On Samsung Galaxy: visit the Airalo website in Chrome, search Mauritius, and buy the 1GB plan at $8.10 — Samsung's built-in eSIM installer handles the profile download. Compare providers to find the cheapest plan.
- On Google Pixel: go to Settings > Network > SIMs > Download a SIM and scan the QR code — do this before your flight to Sir Seewoosagur Ramgoolam (MRU) so it activates the moment you land
- Do this before you land in Mauritius — carrier roaming charges start the moment your phone registers on a foreign network. The how-to-turn-off-data-roaming guide shows you exactly where to find the toggle.
- Returning traveler: your phone may auto-connect to my.t from a prior trip — if data does not flow, confirm the Airalo eSIM is set as the active data line in your cellular settings
- Keep your carrier SIM active for calls and texts via WiFi Calling — no voice roaming charges apply
Data tips
How to use less data in Mauritius
Download offline maps before your trip — Google Maps and Maps.me both support offline areas. This cuts navigation data usage from 50 MB/hour to near zero. WhatsApp messages use minimal data. Voice calls over WhatsApp use about 30 MB/hour. Video calls consume 250 MB/hour. Streaming video is the biggest drain at roughly 1 GB/hour.
Regional context
What Africa roaming agreements mean for Mauritius visitors
A few things to know before turning off carrier roaming in Mauritius:
Mauritius SIM registration: Passport required. A travel eSIM purchased abroad bypasses local SIM registration requirements at the point of sale.
Compact island with good coverage everywhere
Most resorts have free WiFi
my.t has best coverage including mountainous interior
Forgot your eSIM?
Mauritius post-arrival eSIM guide: airport, hotel, and emergency options
You landed in Mauritius without an eSIM. Here is what that costs and what you can still do.
All four major providers — Airalo, Holafly, Saily, and Nomad — allow post-arrival purchase and installation over WiFi. You do not need a local SIM to buy an eSIM. Sir Seewoosagur Ramgoolam (MRU) has free WiFi in the arrivals hall. Connect there, open Airalo or Holafly, and install a 1GB plan at $8.10 before you leave the terminal. If airport WiFi is unavailable, hotel lobby WiFi works as a fallback — most front desks in Mauritius give you the password at check-in. Last resort: turn on carrier data long enough to download the eSIM provider app (~5 MB, roughly $10 on AT&T pay-per-use), then switch to the installed eSIM immediately. That one-time charge is far below a full day at AT&T's $12/day rate.
Mauritius FAQ
Mauritius eSIM & roaming questions
How much does carrier roaming cost in Mauritius?
Verizon TravelPass and AT&T International Day Pass both bill $10/day in Mauritius. T-Mobile offers free international data, but caps speed at 256 Kbps — unusable for navigation or video. Pay-per-use rates without a plan can exceed $2,000/GB on AT&T. An eSIM on my.t starts at $8.10 for 1GB, delivering full 5G speeds on the same local towers your carrier roams through.
Is T-Mobile's free international data fast enough in Mauritius?
No. T-Mobile's free tier: 256 Kbps. Google Maps minimum: 500 Kbps. Video calls: 2,000 Kbps. Streaming: 1,500 Kbps. The free tier covers text-only WhatsApp and nothing else in Mauritius. T-Mobile's paid upgrade runs $15/day on my.t's towers. A travel eSIM on the same my.t towers costs $5.06/GB at full 5G speed — no daily charge, no speed cap.
How is my roaming bill calculated in Mauritius?
Three billing models for Mauritius data. Model 1: per-day pass (AT&T $10/day, Verizon $10/day) — charges on any day your phone touches the network, even from background apps. Model 2: per-MB (AT&T $2.05/MB without a pass, $2,099/GB). Model 3: flat-rate eSIM at 1GB for $8.10 — one payment, fixed cost, no daily or per-MB charges. Model 3 is the only one where a background app sync costs nothing extra.
Can I get a refund on a travel eSIM for Mauritius if I don't use it?
Refund policies vary by provider. Most eSIM providers offer a full refund only if the plan has never been installed or activated. Once the QR code is scanned and the profile downloaded to your device, refunds are rarely issued even if you never traveled. AT&T International Day Pass at $10/day can be cancelled before departure — your account is only billed on days the pass activates in Mauritius. For an eSIM on my.t at $5.06/GB, read the refund clause before purchase. Plans under $10 total carry no refund window regardless of usage. Rates checked June 2026.
Can I send and receive SMS texts with a travel eSIM in Mauritius?
Data-only eSIM plans in Mauritius do not include SMS. Text messages go through your home SIM. With data roaming disabled on your home SIM, incoming SMS still arrives because texts travel on the voice network, not the data network. iMessage and WhatsApp messages route over the eSIM's data connection on my.t at $5.06/GB. Standard SMS from your home number works without activating data roaming. The cost risk: if your home SIM accidentally connects data in Mauritius, AT&T charges $10/day or $2.05/MB. Keep data roaming disabled on the home SIM. Rates checked June 2026.
Do US carriers support roaming in Mauritius?
AT&T covers Mauritius at $10/day. Verizon covers most African countries at $10/day. T-Mobile includes Mauritius at 256 Kbps (free but unusable for data-heavy apps). A travel eSIM on my.t provides full 5G speeds at $5.06/GB — the same carrier infrastructure as roaming, at a fraction of the cost.
Is mobile data reliable enough in Mauritius to replace carrier roaming?
Mauritius has 1 carrier providing 5G coverage. Urban and tourist areas have solid coverage; rural regions may have gaps. A travel eSIM connects to my.t — the exact same network carrier roaming uses — at $5.06/GB. Coverage quality is identical to what AT&T or Verizon routes through.
How much does a 10-day trip to Mauritius cost in carrier roaming versus an eSIM?
AT&T International Day Pass for 10 days: $100. Verizon TravelPass: $100. T-Mobile high-speed: $150. A travel eSIM on my.t at $5.06/GB for 10 days at 1.5 GB/day average costs roughly $75.90. The eSIM saves over 80% versus any carrier's paid roaming option. Rates checked June 2026.
Does carrier roaming work in rural areas of Mauritius, or only in cities?
Both carrier roaming and travel eSIMs connect through my.t's towers in Mauritius. Coverage outside major cities depends on how widely my.t has deployed — the same gaps that affect an eSIM also affect AT&T and Verizon roaming. Urban centers and tourist corridors have consistent signal; rural and off-road areas may have limited or no service. There is no coverage advantage to choosing carrier roaming over an eSIM; both are subject to the same my.t network footprint.
How much does carrier roaming cost for a week in Mauritius?
AT&T: $70/week (International Day Pass at $10/day). Verizon: $70/week (TravelPass). T-Mobile: free at 256 Kbps or $105/week for usable speed. The cheapest eSIM for Mauritius starts at $5.06/GB on my.t's 5G network — better per-GB value than all three carriers.
Fact check
eSIM and roaming misconceptions for Mauritius travelers
eSIM drains more battery than a physical SIM
An eSIM is a programmable chip embedded in your phone's hardware — the same radio module that handles physical SIM cards. It draws no additional power beyond what a physical SIM uses. Battery drain in Mauritius is driven by signal strength and data activity, not by SIM format. Weak signal forces your radio to search harder — that is the actual drain variable regardless of SIM type.
A VPN eliminates roaming costs
A VPN changes the routing of your data packets — it does not change which cellular network your phone connects to. In Mauritius, your phone attaches to my.t's towers whether or not a VPN is active. AT&T still bills $10/day for that connection even when you tunnel traffic through a VPN server. A VPN also adds 10–20% overhead to your total data consumption on top of the carrier charge.
eSIMs use different, slower networks
A travel eSIM in Mauritius connects to the same my.t towers as AT&T and Verizon roaming. The radio frequency bands, signal strength, and 5G speed are identical. AT&T's roaming agreement with my.t and a travel eSIM provider's agreement with my.t both access the same physical infrastructure. No speed penalty exists for switching from roaming to eSIM.
Our recommendation
Mauritius trip connectivity: the cost outcome
For Mauritius, Airalo is the strongest fit. Airalo covers Mauritius on my.t's network with the widest plan selection in the market. A 1GB plan costs $8.10. Regional bundles cover neighboring countries on a single eSIM. The app tracks data usage in real time — helpful for managing a fixed-GB plan. Holafly is the alternative for heavy data users — unlimited daily plans start at $9.72/day.
7 days in Mauritius: $37 difference between carrier roaming and eSIM
Mauritius eSIMs run on the same local towers as carrier roaming. The cost is $5.06 vs $42 for a week.
