Know Your Carrier's Rates
AT&T: $10/day (auto-triggered). Verizon: $10/day (2GB cap). T-Mobile: free at 256 Kbps (too slow for maps). Without any plan: $2.05/MB. Know these numbers so you can calculate what you are saving.
At the Airport
When to Activate Your eSIM
After clearing customs at Sir Seewoosagur Ramgoolam (MRU), before leaving the terminal. Do not enable your eSIM during layovers. Each country your phone connects to triggers a separate carrier charge. Your eSIM plan timer starts at first network connection.
Airport SIM Counter vs eSIM
Sir Seewoosagur Ramgoolam (MRU) has SIM card kiosks. Typical cost: $5-10 for 5-10GB / 28 days. Your eSIM is already installed. No queue, no language barrier, no passport handover.
Some airport SIM counters in Mauritius only accept local currency. You land with MUR still to collect from an ATM. The SIM counter wants cash. The ATM has a queue. AT&T charges $10 while you sort out the currency problem. An eSIM processes in your home currency before departure — no foreign currency needed, no ATM stop, no waiting for cash. Plans on my.t start at $8.10 for 1GB, charged to your regular card on home soil. Land with connectivity already active and your wallet untouched.
Airport WiFi
WiFi at Sir Seewoosagur Ramgoolam (MRU) is available for eSIM QR code installation if you did not install at home. Speed and reliability vary. Free tiers are typically time-limited.
First Connection Test
- Open your browser and load any page to confirm data works
- Check the status bar for my.t carrier name
- Verify your home SIM still receives calls
- Run a speed test at fast.com
iPhone Roaming Settings for Mauritius
iPhone 14 and newer models sold in the US are eSIM-only. Both SIM slots are digital. Open Settings > Cellular to see your installed lines. Tap your home carrier line (AT&T, Verizon, or T-Mobile). Turn off Data Roaming under Cellular Data Options. This one toggle prevents the $10/day charge on my.t in Mauritius. Next, install a Mauritius travel e SIM: Settings > Cellular > Add eSIM. Scan the QR code from your eSIM provider or use the provider's app. After installation, go to Settings > Cellular > Cellular Data and select the travel eSIM as your data line. Your home carrier stays active for calls and texts. The eSIM handles all data on my.t at $8.10 for 1GB. Over 7 days, this saves $61.90 versus AT&T Day Pass.
Samsung Roaming Settings for Mauritius
Samsung's built-in Data Saver reduces background data usage on your Mauritius eSIM. Settings > Connections > Data Usage > Data Saver ON. This restricts background data for all apps except those you whitelist. Combine with Data Roaming OFF on your AT&T or Verizon line (Settings > Connections > Mobile Networks > Data Roaming OFF). A 1GB e SIM on my.t at $8.10 stretches further with Data Saver active. Whitelist Maps, your messaging app, and your eSIM provider's app. Block background data for social media, news, and streaming apps. Download content over WiFi at your hotel. Data Saver cuts background consumption by 30-50% on Samsung devices.
Pixel Roaming Settings for Mauritius
Google Pixel 9 and Pixel 8 on Android 15: open Settings > Network & Internet > SIMs. Tap your home carrier (AT&T, Verizon, or T-Mobile). Toggle Roaming OFF. This prevents the $10/day charge on my.t in Mauritius. Install a travel eSIM: Settings > Network & Internet > SIMs > Add SIM (or download from your provider's app). After scanning the QR code, return to Settings > Network & Internet > SIMs and tap the new e-SIM entry. Set it as your mobile data SIM. Your home carrier handles calls and texts. The eSIM handles all data on my.t at $8.10 for 1GB. Pixel phones support per-SIM roaming toggles, so roaming stays OFF on your home carrier and ON for the eSIM simultaneously.
Dual SIM Configuration for Mauritius
iOS 18 and Samsung One UI 6 allow per-app data line assignment on dual-SIM devices. In Mauritius, assign all data-heavy apps to your eSIM line on my.t. iPhone: Settings > Cellular > scroll to apps > assign each app to the eSIM line. Samsung: Settings > Connections > SIM Manager > tap each app to assign a SIM. Assign Maps, browser, social media, and messaging to the eSIM. Keep the Phone and Messages apps on your home SIM. This prevents accidental data roaming on your home carrier when a specific app makes a network request. The e-SIM at $8.10 for 1GB handles all assigned apps. AT&T charges $10/day if any single app routes data through the home SIM. Per-app assignment eliminates that risk.
WiFi Calling Setup for Mauritius
WiFi Calling in Mauritius provides a free voice alternative to carrier roaming. WiFi availability is good. Enable WiFi Calling before departure on your home SIM. Connect to hotel or cafe WiFi in Mauritius. Calls route through your US carrier network at domestic rates. No roaming surcharge. Your eSIM on my.t handles data at $8.10 for 1GB. WiFi Calling handles voice for free. The combination eliminates both the $10/day data charge and the $1-3/minute voice roaming fee.
Background App Settings for Mauritius
Background App Refresh (iPhone)
Settings > General > Background App Refresh
Disable globally or per-app. Background refresh on my.t in Mauritius consumes 50-200 MB/day without you opening any app. At $2.05/MB without a roaming plan, that is $102-410/day in silent charges. With an eSIM, this data counts against your plan. Disable for social media, news, and shopping apps. Keep enabled for Maps and messaging.
Mail Fetch vs Push (iPhone)
Settings > Mail > Accounts > Fetch New Data
Switch from Push to Fetch (every 30 minutes or Manual). Push email checks my.t's network every 15-60 seconds in Mauritius. At MUT (UTC+4) timezone, overnight pushes sync while US colleagues send daytime emails. Fetch reduces email data by 60-80% compared to Push. Each push check: 0.5-2 MB.
iCloud Photos cellular upload (iPhone)
Settings > Photos > Cellular Data OFF
iCloud uploads every photo to the cloud over cellular by default. After a day of sightseeing in Mauritius, 50-200 photos queue for upload overnight. Each high-res photo: 3-8 MB. Total overnight upload on my.t: 150-1,600 MB. At $2.05/MB: $307-3,280 without a plan. With an eSIM, this drains your data balance. Upload photos manually on hotel WiFi instead.
Data Saver (One UI) (Samsung)
Settings > Connections > Data Usage > Data Saver ON
Samsung Data Saver restricts background data for all apps except whitelisted ones. Whitelist Maps, your messaging app, and your eSIM provider app. Block background data for social media, streaming, and news. This reduces background consumption on my.t in Mauritius by 30-50%. Your eSIM data lasts longer without manual intervention.
Auto-sync toggle (Samsung)
Settings > Accounts and Backup > Manage Accounts > Auto Sync Data OFF
Auto-sync pushes email, contacts, calendar, and app data over my.t in Mauritius. Disabling auto-sync stops all account synchronization on cellular. Sync manually on hotel WiFi. Re-enable auto-sync when you return home. This single toggle prevents the largest category of background data usage on Samsung devices.
Adaptive Battery and data (Pixel)
Settings > Battery > Adaptive Battery ON
Pixel's Adaptive Battery restricts background activity for infrequently used apps. In Mauritius, this reduces unnecessary data consumption on my.t without manual app-by-app management. Keep Adaptive Battery ON. It learns your usage pattern and limits background data for apps you rarely open while traveling.
Set data warning and limit (Pixel)
Settings > Network & Internet > SIMs > eSIM > Data Warning & Limit
Set a data warning at 80% of your eSIM plan and a hard limit at 95%. Pixel shows a notification when you approach the warning threshold. The hard limit stops cellular data before you exceed your plan in Mauritius. This prevents overage charges on prepaid eSIM plans and unexpected top-up costs on my.t.
Automatic App Downloads (iPhone)
Settings > App Store > App Downloads: toggle OFF for cellular
A single app update runs 50-500 MB. At $2.05/MB on my.t in Mauritius: $102-1,025 per update without a plan. With an eSIM, one update can consume 10-50% of a small data plan. Disable automatic downloads. Update apps manually on hotel WiFi only. Check for updates before departure so critical apps are current.
Airplane Mode Sequence for Mauritius
Landing sequence at Sir Seewoosagur Ramgoolam (MRU): keep Airplane Mode ON when the plane touches down. Step 1 (while taxiing): open Settings, confirm Data Roaming is OFF on your home SIM. Step 2 (at the gate): turn on WiFi while still in Airplane Mode. Connect to airport WiFi if you need to verify your eSIM profile. Step 3 (after clearing customs): disable Airplane Mode. Your phone finds my.t. Data routes through your eSIM at $8.10 for 1GB. AT&T never connects. The entire sequence takes 60 seconds. The alternative: forget these steps, connect to my.t through AT&T, and pay $10 before you reach baggage claim.
Data Usage Monitoring in Mauritius
Pixel phones on Android 15: Settings > Network & Internet > SIMs > tap your e SIM > App Data Usage. This shows per-app consumption on my.t in Mauritius. Set a data warning: Settings > Network & Internet > SIMs > eSIM > Data Warning & Limit. Warning at 16 GB, limit at 19 GB. Your 20GB plan gives a daily budget of 2.9 GB over 7 days. Pixel shows the most data-hungry apps first. Restrict background data for streaming and social media apps that consume more than 100 MB/day. Keep Maps and messaging unrestricted.
Mauritius-Specific Device Settings
Switch email from Push to Fetch in Mauritius. The MUT (UTC+4) timezone means US business hours overlap with your nighttime. Push email checks my.t's network every 15-60 seconds while you sleep. Each check costs 0.5-2 MB at $2.05/MB without a plan. iPhone: Settings > Mail > Accounts > Fetch New Data > switch to Every 30 Minutes or Manually. Android: open your email app Settings > Sync frequency > Every 30 Minutes or Manual.
Physical SIM cards in Mauritius require passport registration. Passport required An eSIM bypasses this requirement entirely. No store visit, no passport scan, no activation wait. Install before departure on home WiFi. The e-SIM connects to my.t after landing without any registration step. This is the single largest convenience advantage of an eSIM in countries with SIM registration requirements.
Turn Off Roaming: Mauritius Device Guide
iPhone
For iPhone users traveling to Mauritius: go to Settings > Cellular > Cellular Data Options. The Data Roaming toggle prevents $10/day carrier charges.
The Data Roaming toggle on iPhone applies to your primary cellular plan. If you add a travel eSIM for Mauritius, that eSIM's data connection is not affected by the toggle. You control each plan separately.
Samsung

Samsung Galaxy S24 and newer models support dual eSIM. You can add a Mauritius eSIM alongside your carrier eSIM. Disable Data Roaming on the carrier plan and use my.t for data at $101.25/20GB.
Pixel
To turn off roaming on Google Pixel before visiting Mauritius, go to Settings > Network & Internet > SIMs > select your carrier > toggle Roaming off.
With Roaming disabled, your Pixel phone will not bill through your carrier in Mauritius. Add a travel eSIM: Settings > Network & Internet > SIMs > Add SIM. Scan the QR code for 20GB on my.t at $101.25.
Getting Data in Mauritius
Best Way to Get Data
The best way to get data in Mauritius is a travel eSIM on my.t — 20GB for $101.25, activated before you land.
Local SIMs require passport registration at the counter. An eSIM skips the counter entirely. You buy it online, scan a QR code, and connect to my.t's 5G network. The 20GB plan costs $101.25 and lasts your entire 7-day trip.
- Check that your phone supports eSIM (iPhone XS+, Samsung Galaxy S21+, Pixel 3+).
- Buy a Mauritius eSIM: 20GB on my.t for $101.25.
- Scan the QR code: Settings > Cellular > Add eSIM (iPhone) or SIM Manager (Samsung).
- Disable carrier data roaming to prevent simultaneous charges.
- Land in Mauritius with data already active on my.t.
An eSIM costs $101.25 vs carrier roaming at $70 or airport SIM at $5-10 for 5-10GB / 28 days+.
Do You Need an eSIM?
You do not strictly need an eSIM for Mauritius, but it is the cheapest way to avoid $10/day carrier roaming charges.
WiFi in Mauritius is good. Hotels and cafes often have WiFi, but you lose connectivity between hotspots. Maps, ride-hailing, and translation apps need constant data. An eSIM on my.t fills those gaps for $101.25/20GB.
With an eSIM, a 7-day trip to Mauritius costs $101.25 for data. Carrier roaming costs $70.
Top Roaming Tip for Mauritius
Disable data roaming before landing in Mauritius. Use an eSIM on my.t for $101.25/20GB instead of $10/day carrier roaming. Saves $0 over 7 days.
During Your Stay
Stretch Your Data
- Use WiFi for downloads and streaming
- Keep video quality at 480p on cellular
- Disable auto-play on social media feeds

- Compress photos before uploading
WiFi Hunting in Mauritius
WiFi availability: good. Hotels, chain cafes, and libraries are reliable WiFi sources. Coworking spaces offer the fastest connections.
Tethering and Hotspot
Share your eSIM data with travel companions via Personal Hotspot. Most eSIM providers allow tethering. Holafly supports it on all plans. Airalo supports it on most plans. Battery drains faster with hotspot enabled.
Top Up If You Run Out
Buy more data through the provider app. Or purchase a second eSIM. Switch to unlimited daily at $9.33/day for worry-free data. eSIM installation refresher →
The most common roaming mistakes for Mauritius
The Push Notification Trap
One push notification triggers AT&T's $10 daily charge. Weather widgets, email sync, WhatsApp pings. The charge resets at midnight Eastern, not Mauritius local time.
The WiFi Drop Trap
Walking out of hotel WiFi range triggers a carrier connection on my.t. One webpage load on your home SIM costs $10. Keep home SIM data roaming OFF.
The Background Sync Trap
iCloud backup overnight at per-MB rates: $1,025-2,099. A single app update (200 MB): $410. Photo sync and email attachment downloads add up fast. Disable all background sync on your home SIM before departure.
The Departure Day Trap
Carrier charges apply on departure day. Your phone connects to my.t at Sir Seewoosagur Ramgoolam (MRU) during check-in, triggering an extra $10 charge. Disable roaming on your home SIM before leaving your hotel.
The Transit Layover Trap
Each country layover triggers a separate $10/day charge. A flight with one layover means two countries, two charges. Keep airplane mode on during all layovers.
More Mistakes to Avoid
Forgot to disable roaming
Data roaming left on triggers AT&T's $10/day charge the moment your phone connects to my.t in Mauritius. One push notification activates the full daily charge. Disable it in Settings before boarding, not after landing.
WiFi Assist left on
iOS WiFi Assist automatically switches to cellular when hotel WiFi weakens. In Mauritius, this routes data through your home SIM on my.t, triggering AT&T's $10/day charge mid-session. Disable WiFi Assist under Settings > Cellular before departure.
Day pass midnight reset misunderstood
AT&T's $10/day pass resets at midnight MUT (UTC+4) time — not local time in Mauritius. Landing at 10pm local time can trigger two separate $10 charges before you sleep. An eSIM on my.t at $8.10 has no midnight reset.
Money-Saving Tricks
eSIM Stacking
Visiting multiple countries? Buy a regional eSIM instead of per-country plans. Airalo offers Asialink, Eurolink, and other regional options. Delete expired profiles to free eSIM slots on your phone.
WiFi Calling for Free Voice
Use WiFi Calling on your home number for free inbound and outbound calls. iPhone: Settings > Phone > WiFi Calling. Android: Settings > Network > WiFi Calling. Works alongside your eSIM data. No per-minute carrier roaming charges.
Offline Everything
Download before departure: maps, translation packs, entertainment (Netflix and Spotify offline mode), boarding passes, and hotel confirmations. This reduces daily data usage from 1.5 GB to under 500 MB.
Family and Group Savings
4 phones × $10/day × 7 days = $280 carrier cost. 4 eSIMs at $8.10 each = $32.40. Savings: $247.60. Or share one eSIM via hotspot for even more savings.
Roaming charges in Mauritius roaming tips
How do I disable roaming for AT&T, Verizon, and T-Mobile in Mauritius?
AT&T: log into myAT&T app > Account > Manage Plan > International > disable International Day Pass. Verizon: My Verizon app > Plan > Travel > remove TravelPass. T-Mobile: dial 611 or use the T-Mobile app to disable international features. On your phone itself, disable data roaming: iPhone Settings > Cellular > Data Roaming (off). This blocks carrier data in Mauritius regardless of plan settings. Without a plan, AT&T charges $2.05/MB, Verizon charges $2.05/MB, and T-Mobile throttles to 256 Kbps. An eSIM on my.t at $8.10 gives full-speed data without any carrier involvement.
Can background apps trigger roaming charges in Mauritius?
Yes, background apps are one of the most common sources of surprise roaming bills. With data roaming enabled and no day pass, AT&T charges $2.05/MB in Mauritius. Background App Refresh on iPhone syncs mail, news, and social apps every 15-30 minutes automatically, including at 3am while you sleep. A single overnight background sync session can accumulate $50-200 in charges without you opening your phone. Disable Background App Refresh before travel: Settings > General > Background App Refresh > Off. Then disable data roaming. An eSIM replaces carrier data entirely. Background syncs bill against the eSIM's flat-rate data at $8.10, not your home carrier's per-MB rate.
How do I get roaming charges removed after returning from Mauritius?
Call within one billing cycle. AT&T: dial 611, say "billing dispute," request "International Roaming Courtesy Credit." First-time waivers cover up to $300. Verizon: call 800-922-0204, select billing, reference "Travel Adjustment." Verizon typically credits 50-100% for first incidents. T-Mobile: 611 or 877-746-0909, ask for "International Roaming Review." T-Mobile is most generous, often waiving the full amount. For charges over $500, request a supervisor escalation and file an FCC complaint at fcc.gov/consumers/guides/filing-informal-complaint if the carrier refuses. Document your Mauritius travel dates and show that charges from my.t were unintentional. Prevent recurrence with an eSIM at $8.10 for 1GB.
What is the cheapest way to avoid roaming charges in Mauritius?
A prepaid eSIM is the most cost-effective way to avoid roaming charges in Mauritius. The best per-GB rate is the 20GB plan at $101.25 total, which works out to $5.06/GB on my.t. Disable data roaming on your home SIM before departure and install the eSIM as your data line. Your home SIM keeps your number active for calls and texts. The eSIM handles all data at flat-rate pricing with no per-day activation fees and no per-MB overages.
How much does roaming cost in Mauritius?
AT&T International Day Pass charges $10/day in Mauritius, totaling $70 for a 7-day trip. Verizon TravelPass costs the same $10/day. Without a day pass, AT&T pay-per-use rates reach $2.05/MB, so a 50 MB Google Maps session costs over $100. T-Mobile includes free international data but throttles to 256 Kbps, which is too slow for navigation or video calls. A travel eSIM connects to my.t starting at $8.10 for 1 GB with no daily activation fee and no per-MB overages.
Can I use WhatsApp and FaceTime with an eSIM in Mauritius?
Yes. WhatsApp, FaceTime, and all messaging apps work normally on an eSIM data connection in Mauritius. WhatsApp voice calls use 0.5-1 MB/minute. Video calls use 3-5 MB/minute. A 30-minute FaceTime video call consumes approximately 150 MB. With an eSIM on my.t starting at $8.10, these calls cost a fraction of carrier international calling rates ($1.00-3.00/minute). Your home number stays on your home SIM for regular SMS and calls.
Should I set up call forwarding before traveling to Mauritius?
Call forwarding sends all calls to another number (such as a Google Voice number), avoiding per-minute roaming charges on incoming calls. Set up before departure: iPhone dial *72 followed by the forwarding number. Android: Settings > Phone > Call Forwarding. Forward to a VoIP number that rings over data. This way, incoming calls arrive through your eSIM's data on my.t at $8.10 instead of your carrier's $1.00-1.29/minute roaming rate. Disable forwarding after returning home: dial *73 (iPhone/AT&T) or turn off in settings. Test forwarding at home before your trip to Mauritius.
Is eSIM coverage as good as carrier roaming in Mauritius?
eSIM coverage in Mauritius is identical to carrier roaming because both use my.t's towers. AT&T and Verizon do not operate their own infrastructure abroad. They pay my.t for roaming access and charge you $10/day. An eSIM accesses the same my.t network directly at $8.10/GB. In practice, eSIM users sometimes get better speeds because carrier roaming agreements can deprioritize international users during congestion. Both methods deliver 5G in Mauritius with typical speeds around 25 Mbps.
Should I enable WiFi Calling before traveling to Mauritius?
Yes. WiFi Calling lets you make and receive calls using your home number over any WiFi network without roaming charges. On iPhone: Settings > Phone > WiFi Calling > toggle on. On Android: Settings > Connections > WiFi Calling > toggle on. Test it at home before departure. With WiFi Calling active in Mauritius, incoming calls ring through WiFi instead of my.t's roaming network. Combined with an eSIM for data ($8.10), you have full phone functionality at zero carrier roaming cost. AT&T, Verizon, and T-Mobile all support WiFi Calling. Check with your carrier to confirm it works for international destinations.
Is there a data limit on carrier roaming plans for Mauritius?
AT&T Day Pass includes your domestic data plan while roaming, but throttles to 128 Kbps after hitting the fair-use threshold (typically 2 GB/day). Verizon TravelPass has the same structure. T-Mobile Go5G includes 5 GB of high-speed data per billing cycle for international use, then throttles to 256 Kbps. None of these plans provide truly unlimited high-speed data in Mauritius. An eSIM on my.t at $101.25 for 20GB gives you a clear data allocation at full speed. When it runs out, you can top up rather than being throttled to unusable speeds.
Why are eSIM plans expensive for Mauritius?
Mauritius has limited carrier competition. CHILI controls most of the mobile market, keeping wholesale rates high. This flows through to travel eSIM prices: 1 GB costs $8.10 versus under $3 in competitive markets. Even at these rates, an eSIM is cheaper than carrier roaming: AT&T charges $10/day regardless of usage. The eSIM at $5.06/GB only charges for data you actually consume.
Do I need to register a SIM card in Mauritius?
Passport required This applies to local physical SIM cards only. A travel eSIM installed before departure does not require local registration. It activates through your provider's app and connects to my.t without any in-person paperwork. Plans start at $8.10.
Should I get an eSIM or a physical SIM card in Mauritius?
An eSIM is faster and cheaper for most travelers to Mauritius. Install it before departure with no airport queue, no passport paperwork, and no language barrier. Passport required eSIM plans on my.t start at $101.25 for 20GB. A physical SIM requires finding a carrier store after landing and may cost more. The eSIM activates in under 5 minutes from your phone settings. Physical SIMs involve waiting 20-45 minutes at an airport counter and typically cost 20-40% more than eSIM plans for the same data.
Can I rely on hotel WiFi instead of buying data for Mauritius?
Hotel WiFi in Mauritius is a supplement, not a replacement. WiFi availability varies widely by hotel and region. Common issues: slow speeds (2-10 Mbps shared among guests), unstable connections, login walls that expire, and no coverage outside the hotel. You need mobile data for navigation, ride-hailing, real-time translation, and communication between locations. An eSIM on my.t at $8.10 provides mobile data everywhere. Use hotel WiFi for large downloads and video streaming to conserve eSIM data. Rely on the eSIM for everything outside the hotel.
Save money on data in Mauritius.
A 1GB eSIM costs $8.10 on my.t. AT&T charges $70 for the same 7 days.
