Airport options
Nouakchott-Oumtounsy International Airport (NKC): SIM card vs eSIM cost
Buying a SIM card at the airport in Mauritania means waiting in line after a long flight, handing over your passport, and paying a tourist-markup price. A 5GB eSIM at $10 installs in 2 minutes from the provider's app. It activates on Mauritel's network the moment you turn off airplane mode.
Data planning
Data costs for 7 days in Mauritania: carrier vs eSIM
Social media browsing uses about 80 MB/hour. Two hours of Instagram or TikTok scrolling per day adds 160 MB. Stack that with maps and messaging and 1.5 GB per day is a fair estimate for Mauritania. Over 7 days you need 11GB.
At $10 for 7 days, the 5GB plan works out to $1.43/day. AT&T charges $10/day for the same network access on Mauritel. Both connect to the same towers. The billing model is different.
Connectivity
Mauritania data strategy: WiFi vs eSIM

Plan your data
Your Mauritania data budget explained
Summer travel to Mauritania means peak hotel rates, peak airfare, and AT&T roaming at $10/day on top. A 10-day trip generates $100 in AT&T charges alone. A 5GB eSIM on Mauritel at $10 removes that line item — saving $90 regardless of when you travel.
Mauritania has 3 mobile networks. Mauritel carries most of the traffic. Both AT&T and Verizon access Mauritel's towers under roaming agreements. Travel eSIM providers access the same Mauritel towers under similar agreements. You pay AT&T $10/day for an arrangement eSIM providers resell at $2/GB.
WiFi in Mauritania is limited and unreliable in most areas. An eSIM fills the gaps at $2/GB instead of AT&T's $10/day roaming charge. Local prices in Mauritania are in Mauritanian Ouguiya (MRU) (UM), but eSIM plans are priced in USD, eliminating exchange rate uncertainty on your data costs.

Step by step
Cancel carrier roaming before you land in Mauritania

- On iPhone: go to Settings > Cellular > Add eSIM > Use QR Code and scan the Holafly code — do this before your flight to Nouakchott-Oumtounsy International Airport (NKC) so it activates the moment you land
- On Samsung Galaxy: go to Settings > Connections > Mobile Networks, select your home carrier SIM, and turn off Data Roaming. The step-by-step roaming guide has Android screenshots.
- On Google Pixel at Nouakchott-Oumtounsy International Airport (NKC): go to Settings > Network > SIMs and set the Holafly eSIM as the preferred data SIM — LTE on Mauritel confirms in seconds

A few things to know before turning off carrier roaming in Mauritania:

Forgot your eSIM?
Last-minute eSIM options for Mauritania arrivals
You landed in Mauritania 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. Nouakchott-Oumtounsy International Airport (NKC) has free WiFi in the arrivals hall. Connect there, open Airalo or Holafly, and install a 5GB plan at $10 before you leave the terminal. If airport WiFi is unavailable, hotel lobby WiFi works as a fallback — most front desks in Mauritania 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.
Mauritania FAQ
Mauritania eSIM & roaming questions
How much does carrier roaming cost in Mauritania?
A family of four on AT&T in Mauritania pays $40/day ($10/day per line x 4). Over a week that reaches $280. The same family shares one travel eSIM on Mauritel starting at $2/GB — a single purchase covers all devices through tethering. Verizon charges the same per-line rate. T-Mobile includes free data at 256 Kbps, which cannot load a map.
Is T-Mobile's free international data fast enough in Mauritania?
No. At 256 Kbps, T-Mobile's free international tier in Mauritania cannot load a map tile in under 15 seconds. Video calling needs 2 Mbps minimum — eight times what T-Mobile provides for free. Their paid speed upgrade runs $15/day. A 4G LTE eSIM on Mauritel at $2/GB gives you real speeds without the daily fee.
How is my roaming bill calculated in Mauritania?
At 3 days in Mauritania: AT&T costs $30, eSIM costs $2/GB. At 7 days: AT&T $70, eSIM same $2/GB. At 14 days: AT&T $140, eSIM same fixed rate. The eSIM billing model is flat — the longer the trip, the wider the gap. T-Mobile free tier is $0 but too slow at 256 Kbps to be usable beyond text.
Can I stream Netflix and YouTube on a travel eSIM in Mauritania?
Yes. Mauritel's 4G LTE network in Mauritania supports streaming without buffering under normal conditions. Data consumption: Netflix SD uses 700 MB/hour, HD uses 3 GB/hour, 4K uses 7 GB/hour. YouTube at 720p uses 900 MB/hour. AT&T International Day Pass at $10/day covers streaming but bills daily regardless of usage. A travel eSIM at $2/GB charges per GB consumed — 2 hours of Netflix HD costs roughly $12. Download content over hotel WiFi before heading out to cut cellular data use by 90% for entertainment. Rates checked June 2026.
Does my phone automatically connect to roaming in Mauritania?
Yes, if data roaming is enabled. Your phone latches onto Mauritel or another Mauritania carrier the moment the plane lands and your carrier bills at roaming rates — $10/day with a plan, or $2.05/MB without one. Disable data roaming on your home SIM before boarding. A pre-installed travel eSIM can be set to activate on arrival without triggering home carrier charges.
Do US carriers support roaming in Mauritania?
AT&T covers Mauritania at $10/day. Verizon covers most African countries at $10/day. T-Mobile includes Mauritania at 256 Kbps (free but unusable for data-heavy apps). A travel eSIM on Mauritel provides full 4G LTE speeds at $2/GB — the same carrier infrastructure as roaming, at a fraction of the cost.
Is mobile data reliable enough in Mauritania to replace carrier roaming?
Mauritania has 3 carriers providing 4G LTE coverage. Urban and tourist areas have solid coverage; rural regions may have gaps. A travel eSIM connects to Mauritel — the exact same network carrier roaming uses — at $2/GB. Coverage quality is identical to what AT&T or Verizon routes through.
How much does a 10-day trip to Mauritania 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 Mauritel at $2/GB for 10 days at 1.5 GB/day average costs roughly $30. The eSIM saves over 80% versus any carrier's paid roaming option. Rates checked June 2026.
Does carrier roaming work in rural areas of Mauritania, or only in cities?
Both carrier roaming and travel eSIMs connect through Mauritel's towers in Mauritania. Coverage outside major cities depends on how widely Mauritel 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 Mauritel network footprint.
How much does carrier roaming cost for a week in Mauritania?
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 Mauritania starts at $2/GB on Mauritel's 4G LTE network — better per-GB value than all three carriers.
Fact check
3 roaming myths that cost travelers money in Mauritania
T-Mobile includes free international data
T-Mobile's free tier is capped at 256 Kbps in Mauritania — too slow to load a map tile or stream a 30-second clip. Their high-speed add-on costs $5–$15/day depending on destination. Exception: Mexico and Canada get full LTE/5G speed at no charge under the USMCA agreement. Mauritania is not on that list. Rates checked June 2026.
Carrier roaming is more reliable than an eSIM
Reliability is determined by the local carrier's network, not the billing layer above it. AT&T roaming in Mauritania routes through Mauritel. A travel eSIM also routes through Mauritel. Both connections depend on Mauritel's coverage in any given area. AT&T charges $10/day for a connection with zero reliability advantage over the $10 eSIM.
Pay-per-use international data rates are reasonable
AT&T's pay-per-use international data rate is $2.05/MB without an active plan. At that rate, 1 GB costs $2,050. A single Google Maps navigation session in Mauritania loads 50–100 MB — that is $100–$205 at pay-per-use. A 5GB eSIM on Mauritel costs $10 for the same data. Always activate a day pass or eSIM before your flight. Rates checked June 2026.

eSIM vs roaming in Mauritania: the price gap
