On Arrival

Your first minutes at Mauritania's main airport

When to turn on your eSIM

Activate your eSIM after clearing customs at Mauritania's main airport, before you leave the terminal. Do not enable it during a layover at a connecting airport. Most plans start counting from the first network connection, not from installation. Enabling during transit burns a full day of your plan.

Connecting to Mauritel's network

  1. Open Settings on your phone
  2. Go to Cellular (iPhone) or Network & Internet (Android)
  3. Select your travel eSIM line
  4. Enable Data Roaming on that line only
  5. Wait 2-3 minutes for Mauritel's 4G LTE network to register

What if your eSIM does not connect

  1. Toggle Data Roaming off and back on
  2. Restart your phone
  3. Verify the travel eSIM is selected as your cellular data line
  4. Try manual network selection: choose Mauritel

Configuration

Mauritania eSIM network setup

Dual-SIM configuration

Keep your home SIM for calls and texts. Set the travel eSIM as your cellular data line. On iPhone: Settings > Cellular > Cellular Data > select travel eSIM. On Android: Settings > Network & Internet > SIMs > set travel eSIM for mobile data. iMessage and FaceTime should stay on your home number.

Data roaming settings

Installation Methods

Installing your Mauritania eSIM: QR code scan or provider app?

QR Code Scan Method

  1. Purchase your Mauritania eSIM from any provider (Airalo, Holafly, Saily, Nomad). The QR code arrives via email or is displayed in your account dashboard.
  2. Display the QR code on a separate screen — laptop, tablet, or a printed copy. You cannot scan a QR code on the same phone you are installing the eSIM on.
  3. On your phone: iPhone — Settings > Cellular > Add eSIM > Use QR Code. Samsung — Settings > Connections > SIM Manager > Add eSIM > Scan QR Code. Pixel — Settings > Network & Internet > SIMs > Add SIM > Download SIM.
  4. Point your camera at the QR code. The eSIM profile downloads in 5-15 seconds over WiFi.
  5. Tap "Activate" or "Add" when prompted. Label the plan "Mauritania Data."
  6. Disable the eSIM after installation. Enable it after landing at Mauritania's main airport.

Pros:

  • Works with any eSIM provider — universal method across all platforms.
  • No app installation required — uses your phone's built-in Settings flow.
  • The QR code is a one-time-use credential: once scanned, the profile is on your device permanently (until you delete it).
  • Faster initial setup: scanning takes 10 seconds vs app download + account creation.

Cons:

  • Requires a second screen to display the QR code — cannot scan from the same device.
  • Requires WiFi or mobile data for the download. Mauritania's public WiFi is moderate — install at home.
  • If the scan fails, you need the SM-DP+ manual entry code from the confirmation email as a fallback.
  • QR codes are single-use for most providers — losing the email before scanning means contacting support.

Best for: Travelers installing at home before departure, users who prefer not to install additional apps, and anyone setting up a Mauritania eSIM on a secondary phone or tablet.

Provider App Installation

  1. Download your provider's app: Airalo (iOS/Android), Holafly (iOS/Android), Saily (iOS/Android), or Nomad (iOS/Android).
  2. Create an account or sign in. Search for "Mauritania" in the destination field.
  3. Select and purchase your plan. Compare available options.
  4. The app presents an "Install" button for your Mauritania plan. Tap it. The app opens your phone's native eSIM settings and guides you through the process.
  5. Follow the on-screen prompts. The app handles QR code scanning internally — no second screen needed.
  6. After installation, the app shows your plan status: data remaining, validity period, and connected carrier (Mauritel in Mauritania).

Pros:

  • No second screen needed — the app handles the QR scanning or direct provisioning internally.
  • Built-in plan management: monitor data usage, check validity, and view carrier connection status.
  • Easier reactivation: if you visit ${country.name} again, the app stores your purchase history.
  • Some apps (Airalo, Saily) support direct eSIM provisioning — no QR code needed at all.

Cons:

  • Requires downloading a 50-100 MB app before installation — uses storage and initial data.
  • Account creation adds 2-3 minutes to the process.
  • Each provider has a separate app — managing plans across Airalo, Holafly, and Saily means three apps.
  • App updates can temporarily break the installation flow on older OS versions.

Best for: First-time eSIM users who want guided setup, travelers who buy from the same provider regularly, and anyone who wants in-app data monitoring during their Mauritania trip.

Recommendation: Both methods install the same eSIM profile on Mauritel's network. The difference is convenience: the app method is easier for first-time users (guided prompts, no second screen needed), while the QR method is faster for experienced travelers (skip the app, scan in 10 seconds). Either way, install at home over WiFi and leave the Mauritania profile disabled until you land.

Timing

Pre-departure vs on-arrival: Mauritania eSIM timing

Pre-Departure Setup (Recommended)

Set up at home the night before your flight. Your own WiFi provides the clean connection the QR scan needs. Configure the Mauritania eSIM as your data line, test the setup by briefly toggling it on and off, and leave it disabled for travel. At Mauritania's main airport, enable the profile and Mauritel connects within 60-90 seconds. You walk off the plane with data.

Pros:

  • Reliable WiFi at home — no captive portals or unstable airport networks.
  • No time pressure. If the QR code fails, you have hours to contact support.
  • Jet-lag-free setup. Configuring Settings after a 12-hour flight leads to mistakes.
  • Immediate data on landing: Mauritel connects in 60-90 seconds, no WiFi search.
  • No SIM counter detour at Mauritania's main airport.
  • Plan timer does not start until Mauritel registers the profile — no wasted days.

Cons:

  • Must remember to install before departure — not an option if you forget.
  • Plan validity begins on first network connection, not purchase date — but activating during a layover still burns a day.
  • If you change your travel dates after installation, the eSIM sits unused until you travel.

Choose when: Best for: all planned trips. Install 24-48 hours before departure.

On-Arrival Setup at Mauritania's main airport

On-arrival setup means finding WiFi at Mauritania's main airport for the QR scan. Airport WiFi in Mauritania is moderate — captive portals can interrupt the eSIM profile download. You then configure your data line and enable roaming — steps that take 2-3 minutes with full attention but longer when exhausted.

Pros:

  • Plan timer starts immediately after first connection — no risk of accidental activation during layovers.
  • No advance planning needed — works for last-minute trips.
  • eSIM is the only fast option at this airport — no SIM counter detour.

Cons:

  • Requires WiFi for QR scan. Mauritania's airport WiFi is moderate.
  • Jet-lag mistakes: wrong data line, roaming left off, APN entry errors.
  • 5-15 minutes of setup time at the airport instead of immediate data.
  • No SIM counter at Mauritania's main airport — if the download fails, you have no connectivity until you find WiFi elsewhere.

Choose when: Best for: last-minute trips where pre-departure setup was not possible. Requires WiFi — bring a manual SM-DP+ code as fallback.

Verdict: Pre-departure installation is the correct choice for Mauritania. The 5-minute setup at home saves 15-30 minutes at Mauritania's main airport and eliminates WiFi dependency, queue time, and configuration errors. Mauritel's 4G network connects in 60-90 seconds after one toggle.

Verify

Post-activation checklist for Mauritania

eSIM verification checklist for Mauritania
StepWhat to checkIf it fails
Check carrier name in status barYour status bar should display "Mauritel" or "Mattel" within 60-90 seconds of enabling the eSIM. The 4G indicator confirms your connection type.If "No Service" or "Searching..." persists after 2 minutes: Settings > Cellular > Network Selection > turn off Automatic, wait 10 seconds, turn it back on. If Mauritel does not appear, restart your phone.
Verify data line assignmentOpen Settings > Cellular > Cellular Data. Confirm the Mauritania eSIM is selected as the active data line. If your home SIM is selected, all data routes through your home carrier at roaming rates.Tap "Cellular Data" and select the Mauritania eSIM. Disable "Allow Cellular Data Switching" to prevent automatic fallback to your home SIM when Mauritel's signal dips briefly.
Confirm data roaming is enabledSettings > Cellular > [Mauritania eSIM] > Data Roaming must be ON. Most travel eSIM plans route through roaming agreements — data roaming must be enabled for the travel line specifically.Toggle Data Roaming ON for the Mauritania eSIM line only. Leave roaming OFF on your home SIM to prevent accidental charges.
Load a webpage to verify data flowOpen Safari or Chrome and load any webpage. If the page renders within 3 seconds, your Mauritania eSIM is delivering data on Mauritel's 4G network. Slow loads (10+ seconds) indicate APN misconfiguration.If the page does not load: check Settings > Cellular > Cellular Data Network for APN settings. If blank, contact your eSIM provider for the correct APN string for Mauritel's network in Mauritania.
Test messaging appsOpen WhatsApp, Telegram, or iMessage and send a test message. If it delivers within seconds, your data connection is working. Voice and video calls over these apps also work in Mauritania.If messages do not send, verify your data line assignment (step 2) and data roaming status (step 3). Both must be correctly configured.
Verify emergency dialing capabilityEmergency calls to local emergency number work from any active SIM in Mauritania, even without data. With eSIM data active, your phone's emergency SOS feature also shares your GPS location with responders.Emergency calls bypass SIM restrictions. If your eSIM has no data, the call still connects through any available network. Store local emergency number in your phone contacts as "Mauritania Emergency."
Check remaining data balanceOpen your eSIM provider's app (Airalo, Holafly, Saily, or Nomad) and verify your remaining data and validity period. The plan timer started when Mauritel first registered your profile.If the app shows zero data remaining immediately after activation, the plan may have been activated during a layover. Contact your provider's support for a replacement or top-up.

Data Tips

Make your Mauritania eSIM data last longer

Download offline maps before departure

Google Maps and Maps.me allow offline downloads for specific regions. Download Mauritania's major cities before leaving WiFi. Offline maps use zero cellular data for navigation. A single city map is 50-200 MB — download at home, not on your eSIM.

Disable background app refresh

Go to Settings > General > Background App Refresh (iPhone) or Settings > Battery > Background Usage Limits (Samsung). Background refresh consumes 200-500 MB per day without visible activity. Social media apps, news feeds, and email clients refresh constantly. Disable all except essential apps while on your Mauritania eSIM.

Pause cloud sync and auto-backups

iCloud Photos, Google Photos, and cloud backup services upload images and videos over cellular data. A single day of vacation photos can consume 1-3 GB in background uploads. Pause cloud sync: iPhone — Settings > Photos > Cellular Data > toggle off. Android — Google Photos > Settings > Back up & sync > Use cellular data > off. Sync manually over WiFi at your hotel each evening.

Use WiFi when available

Public WiFi in Mauritania is moderate. Hotel WiFi is your most reliable option for heavy data tasks. Save video streaming, large downloads, and cloud backup for your hotel connection. Use your eSIM for maps and messaging during the day.

Set video quality to low on streaming apps

Standard definition video uses about 700 MB per hour. HD uses 1.5-3 GB. If you stream on your Mauritania eSIM, set Netflix, YouTube, and other apps to "Data Saver" or "Low" quality. Better approach: download episodes over WiFi before going out.

Monitor data usage in real time

iPhone: Settings > Cellular > scroll to usage stats for each app. Samsung: Settings > Connections > Data Usage > Mobile Data Usage. Check daily. Set a data warning at 80% of your plan limit: iPhone uses Screen Time limits; Samsung has a built-in data warning under Data Usage settings. Your eSIM provider's app also shows remaining data for your Mauritania plan.

Business

Mauritania eSIM for business travelers: setup and policy guide

Corporate travel to Mauritania runs on data. An eSIM on Mauritel's 4G network delivers standard LTE speeds — fast enough for video calls, VPN tunnels, and cloud document access. Install on each traveler's phone before departure. No purchase orders, no carrier contracts, no hardware logistics.

Multi-device management

Multi-device deployment for Mauritania: purchase one eSIM per phone. Each profile connects to Mauritel independently. For teams of 3 or more, Airalo offers business accounts with centralized billing and bulk QR code distribution. Corporate phones under MDM (Jamf, Intune, VMware Workspace ONE) may require an IT exception to install eSIM profiles. Request the exception 72 hours before departure to avoid last-minute blockers.

VPN and security

VPN works normally in Mauritania on Mauritel's network. No restrictions on VoIP services — Zoom, Teams, Meet, WhatsApp, and FaceTime all function without tunneling. Use your corporate VPN only for internal resources (intranet, file servers, internal tools). This saves 10-15% data compared to running VPN for all traffic.

Expense tracking

Track your Mauritania eSIM as a travel communication expense. The provider receipt serves as documentation: plan type, price (USD), destination, and validity dates. No carrier invoices, no prorated charges, no surprise line items. Compare this to corporate roaming packages that charge $10-15/day for the same Mauritel coverage.

Emergency protocol

Emergency contacts for Mauritania business travel: local emergency services at local emergency number, your corporate security line, and your travel insurance provider. Store all three in your phone before departure. With Mauritel data active, you can share live GPS coordinates, access your corporate emergency app, and reach your company's 24/7 duty officer via messaging or email.

Transfer

Phone upgrade during your Mauritania trip: eSIM transfer guide

Replacing your phone during a Mauritania trip does not mean losing your eSIM data. The profile on Mauritel's network can move to a new device through direct transfer or provider reissue. Have your original provider confirmation email accessible — it contains the SM-DP+ details needed for manual reactivation.

iPhone to iPhone

iPhone to iPhone (iOS 17+): Settings > Cellular > tap the Mauritania eSIM > Transfer to Nearby iPhone. Both phones must be within Bluetooth range, signed into the same Apple ID, and running iOS 17 or later. The transfer takes 2-5 minutes. Your Mauritel connection resumes on the new device within 60 seconds. Quick Start during initial setup also offers eSIM transfer as part of the migration flow.

Android transfer

Samsung to Samsung or Pixel to Pixel: most Android manufacturers do not support direct eSIM transfer between devices. You need a new QR code from your eSIM provider. Contact Airalo (in-app chat, 4 min avg), Holafly (WhatsApp +34 644 44 37 97), or Saily (email support) and request a profile reissue for your Mauritania plan. The provider deactivates the old profile and issues a new QR code for the new device. Your remaining data and validity transfer to the new profile.

Cross-platform

iPhone to Android or Android to iPhone: cross-platform eSIM transfer requires provider intervention. Contact your provider's support, explain the device change, and request a new QR code. The Mauritania plan (remaining data and validity on Mauritel's 4G network) transfers to the new profile. Install the new QR code on the replacement device, configure the data line, and enable roaming. Mauritel registers in 60-90 seconds.

Warning: Do not delete the eSIM profile from your old device before confirming the transfer or receiving a new QR code. Deletion without a backup code may permanently deactivate the profile. Contact your provider first, complete the transfer process, and only then remove the old profile.

After Your Trip

Post-trip: what to do with your Mauritania eSIM

  1. Disable the Mauritania eSIM immediately: Settings > Cellular > [Mauritania Data] > turn off "Turn On This Line."
  2. Re-enable your home SIM as the primary data line: Settings > Cellular > Cellular Data > select your home SIM.
  3. Turn off data roaming on all lines: Settings > Cellular > each line > Data Roaming > Off.
  4. Check your Mauritania data usage in your provider app — note remaining balance for records or potential refund.
  5. Decide whether to keep or delete the Mauritania eSIM profile (see guidance below).

Your Mauritania eSIM stays on your phone after the trip unless you remove it manually. For repeat travelers: keep it and buy a new plan next time. For one-time visitors: delete it under Settings > Cellular > Remove Cellular Plan. Either way, disable the Mauritania eSIM immediately after returning home — leaving it active may trigger unexpected connection attempts on other networks.
