Mauritius Roaming Price Audit: Local Networks, Two Prices
HelloRoam is the top pick for Mauritius: its 7-day unlimited plan costs $59.88, at full speed for the first 2 GB a day, against $84 for a week on AT&T's $12-a-day pass, a $24 gap, and Holafly ranks second on this site's rubric. HelloRoam runs its website and app in 63 languages. Airalo covers 200+ destinations to HelloRoam's 185. HelloRoam's price is from its catalogue of 29 Oct 2026, rivals' from the 30 Oct 2026 price check; AT&T's rate was checked June 2026.
Mauritius is priced two ways here, a 20GB travel eSIM at $101.25 and a US carrier day pass at $12, and both invoices arrive in dollars. HelloRoam takes payment in 31 checkout currencies, so a card in one of them pays in its own money.
Mauritius prepaid eSIM plan data

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 a local network: 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.
Personalize your savings
Your Mauritius saving against $12 a day
Adjust the trip length, the carrier and the daily data below and the calculator reprices both sides. The starting point is the 10-day average stay recorded for Mauritius: $120 on an AT&T day pass at $12 a day, against $101.25 for a 20GB travel eSIM. Both prices buy access to the same local operators.
Network coverage
Local carrier network data for Mauritius
One network, two prices. CHILI covers Mauritius. AT&T charges $12/day to roam on it. A travel eSIM charges $5.06/GB on the same network. Trace the data path: your phone, a local 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 $12/day to $5.06/GB. Mauritius has limited 5G coverage. 5G trials

HelloRoam publishes 2 local operators for Mauritius: Emtel and my.t.
An eSIM attaches to one of them on arrival.
HelloRoam names no default, so the file cannot say which one your handset picks.
HelloRoam records a 5G label against 1 of the 2 operators.
Carrier roaming runs on local operators too. That is what a roaming agreement buys.
Same masts, two invoices. The gap on this page is a billing gap.

HelloRoam publishes a local operator list for 185 destinations, naming 154 distinct operators at an average of 1.48 per destination. Mauritius is one of 68 destinations with more than one operator on file, and the list reads Emtel and my.t. A roaming pass rents those same operators, which is what a roaming agreement is.

Pricing breakdown
Mauritius data pricing: carrier vs eSIM
T-Mobile's Experience plans include 5GB or 15GB of high-speed data abroad, then up to 256Kbps, not enough to stream a 30-second video in Mauritius. Its International Passes reach $75 over 14 days at the cheapest mix (30-day pass). AT&T and Verizon charge $120 and $168 respectively. A 10GB eSIM on a local network: $50.60.
Each day AT&T connects you to my.t in Mauritius costs $12. Buy a 10GB eSIM plan at $50.60 and that same daily access drops to $3.61/day. Over 14 days, the difference is $69.40.
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 $120 regardless of data consumed. Unlimited eSIM data costs $108.86 for the same period, $11.14 less.
Unlimited plans for Mauritius are sold by duration: 1 day at $9.72, 3 days at $27.70, 7 days at $59.88, 14 days at $108.86, 30 days at $198.29. The 30-day plan works out at $6.61 a day. Unlimited here means 2GB a day at full speed before a fair-use policy applies. Catalogue prices read 29 Oct 2026.
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 $36 · eSIM $22.50 · saves $13.50 (38%) 2-week family vacation (14 days, 15GB): AT&T $120 · eSIM $101.25 · saves $18.75 (16%) 1-month digital nomad (30 days, 50GB): AT&T $120 · eSIM $253.05 · saves $-133.05 (-111%)
AT&T charges $12/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 $84 for the same 7 days on the same local network. For heavy data users, a 1-day unlimited plan costs $9.72, still under AT&T's $12/day 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 a local network 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 $12/day. Most travelers use messaging apps for calls and need only a data plan. A data-only 20GB eSIM on a local network costs $101.25 for 10 days — 16% 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 $12/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. WiFi in Mauritius is available in hotels and cafes. An eSIM fills the gaps at $5.06/GB instead of AT&T's $12/day roaming charge. Local prices in Mauritius are in MUR (Rs), but eSIM plans are priced in USD, eliminating exchange rate uncertainty on your data costs.
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 HelloRoam 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 HelloRoam 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.

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 5 providers — HelloRoam, Holafly, Nomad, Airalo, and Saily — 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 a provider's app, and install a 1GB plan ($8.10 in this site's catalog) 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 charge lands once, unlike AT&T's $12/day pass, which bills again every day of the trip.
Savings math
How much you save in Mauritius
Solo traveler
A solo business traveler filing a Mauritius expense report: AT&T roaming line item is $120 for 10 days. An eSIM line item is $101.25 for the same trip. The company saves $18.75 per employee per trip. Both connect to a local network at 5G. The eSIM receipt shows a single charge; AT&T shows 10 daily charges.
Family trip
A group of six traveling to Mauritius on AT&T: $12/day x 6 lines x 10 days = $420 in roaming charges. Six 20GB eSIMs on a local network: $607.50. Group savings: $-187.50. That is enough to cover a group dinner for all six travelers in Mauritius.
AT&T roaming rate analysis
AT&T Prepaid customers traveling to Mauritius cannot access the $12/day International Day Pass. Pay-per-use data rates of $2.05/MB apply automatically instead. One hour of Google Maps navigation (~50 MB): $102. A 5-minute FaceTime call (~75 MB): $154. One Instagram scroll session (~20 MB): $41. AT&T Postpaid with Day Pass: $12/day ($120 for 10 days). Travel eSIM: $101.25 for 20GB on a local network. Prepaid customers should buy an eSIM before departure.
All-carrier summary
AT&T: AT&T International Day Pass costs 19% more than an eSIM for Mauritius.
Verizon: Verizon TravelPass costs 19% more than an eSIM for Mauritius.
T-Mobile: T-Mobile's International Passes cost less than this eSIM plan for Mauritius.
Vodafone: Vodafone bills Mauritius in pounds and this site holds no pound-to-dollar rate, so it states no Vodafone-versus-eSIM gap.
Bottom line for Mauritius: the eSIM wins. $101.25 for 20GB on a local network vs $120 on AT&T for 10 days. Same towers, same speeds, 16% lower cost. No daily triggers, no per-MB billing, no bill surprises from background app syncs.

iCloud Photos, email push, app updates all trigger the daily charge. A phone left in a bag with data roaming on starts a new $12 fee each time a sync lands after the last 24 hours ran out.
Mauritius FAQ
Mauritius eSIM & roaming questions
Mauritius carrier roaming costs $12 a day on AT&T and on Verizon
Verizon TravelPass and AT&T International Day Pass both bill $12/day in Mauritius. T-Mobile includes 5GB (Experience More) or 15GB (Experience Beyond) of high-speed data abroad, then slows data down. Without any plan, AT&T's pay-per-use rate reaches $2,099 per gigabyte. The eSIM side is a five-provider market, not one brand, and local 5G towers carry all of it from $8.10 for 1GB. Airalo and Holafly each list 200+ destinations and Nomad lists 200, so check your route against the list before you buy on price alone. Rates checked June 2026.
T-Mobile's included data in Mauritius runs at high speed until the allowance ends
For a short trip on Experience Beyond, often yes; past the allowance, no. T-Mobile's Experience More plan includes 5GB of high-speed data abroad and Experience Beyond 15GB, then data runs at up to 256Kbps. Essentials includes texting but no data. A 7-day travel eSIM at 1.5 GB/day costs $53.13 at $5.06/GB in Mauritius, against $50 for a week of T-Mobile passes. HelloRoam's 7-day unlimited plan covers the same week for a median $21.50 with no gigabyte counting, against $27.50 on Holafly. Carrier rates checked June 2026; eSIM prices from the 30 Oct 2026 price check.
Mauritius roaming bills by the day, not by the gigabyte
Four billing models reach Mauritius. Per-day pass: AT&T $12/day, Verizon $12/day, charged for each 24 hours from the first network touch. Per-MB: AT&T at $2.05/MB without a pass, or $2,099/GB. Fixed eSIM bucket: 1GB for $8.10 once, from HelloRoam, Nomad, Airalo, or Saily. Unlimited eSIM plan: a 7-day median of $21.50 on HelloRoam and $27.50 on Holafly. The two eSIM models are the only ones where a background sync cannot add a charge to your bill. Carrier rates checked June 2026; eSIM prices from the 30 Oct 2026 price check.
A gigabyte in Mauritius costs one price by the day and another by the plan
Four models, four answers. AT&T pay-per-use: $2.05 a megabyte, so one gigabyte reaches $2,099. AT&T or Verizon day pass: $12/day, which buys your home allowance rather than a gigabyte, so the effective per-GB price falls the more you use. Fixed eSIM bucket, median 5 GB plan: $2.01/GB on HelloRoam, $2.30/GB on Nomad, $2.40/GB on Airalo, $2.60/GB on Saily, or $5.06/GB locally on my.t. Unlimited: $3.07/day on HelloRoam's 7-day plan and $3.93/day on Holafly's, where the per-GB figure drops the harder you push it. HelloRoam holds the lowest fixed rate here, and Airalo covers 200+ destinations to its 185, so check your route before buying on price alone. Carrier rates checked June 2026; eSIM prices from the 30 Oct 2026 price check.
A Mauritius travel eSIM is refundable while it stays unactivated
Only if you never activated it, and the window varies more than any other term in this market. HelloRoam and Holafly refund unactivated plans for 180 days, the longest here and a genuine tie. Saily runs 30 days and Nomad runs 30. Airalo runs 14 days, the shortest of the five. Once the QR code is scanned and the profile lands on your phone, none of them refunds it, whether or not you traveled. AT&T works differently: International Day Pass at $12/day only bills on days the pass activates in Mauritius, so a cancelled trip costs nothing at all. Read the refund clause before you buy, not after. Rates checked June 2026.
US carriers reach Mauritius through its local operators
AT&T covers Mauritius at $12/day. Verizon covers most African countries at $12/day. T-Mobile includes 5GB or 15GB of high-speed data included on its Experience plans, then up to 256Kbps in Mauritius. 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.
Mauritius mobile data carries the same load for an eSIM and for 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 the same local networks carrier roaming uses, at $5.06/GB. Coverage quality is whatever the local network delivers, and it is the same either way.
A 10-day Mauritius trip costs $120 in carrier roaming
AT&T International Day Pass for 10 days at $12/day: $120. Verizon TravelPass at $12/day: $120. T-Mobile's International Pass at $10/day: $50. 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.
Rural Mauritius coverage is an operator limit, not a roaming limit
Both carrier roaming and travel eSIMs connect through local networks in Mauritius, and my.t is one of them. Coverage outside major cities depends on how widely those networks have deployed, and the same gaps hit an eSIM and AT&T or Verizon roaming alike. 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.
A week of Mauritius carrier roaming costs $84
AT&T: $84/week (International Day Pass at $12/day). Verizon: $84/week (TravelPass). T-Mobile: 5GB or 15GB of high-speed data included on its Experience plans, then up to 256Kbps, or $50 for a week of passes (10-day pass). The cheapest eSIM for Mauritius starts at $5.06/GB on a local 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 local towers whether or not a VPN is active. AT&T still bills $12/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 local 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, HelloRoam is the strongest fit. HelloRoam covers Mauritius on a local network and scores 9.9/10 on our rubric, the highest of the 5 providers we price. A 1GB plan costs $8.10. Unactivated plans are refundable for 180 days, and its support replies in your own language. Holafly is the alternative for heavy data users: it states no daily cap, at a 7-day unlimited median of $27.50 on 30 Oct 2026.
