Best eSIM for Mauritania

Nomad is the only one of the three big travel eSIM brands with a Mauritania plan, and every package it sells runs on Mauritel. Prices start at 9 dollars for 1 GB over seven days and climb to 49 dollars for 10 GB over thirty. Airalo and Holafly have no Mauritania product page at all; Airalo's Africa regional pack does list the country, but its cheapest tier is 11 dollars for 1 GB over three days, so it only makes sense if Senegal or Mali is on the same ticket. Against that, a local line costs 50 ouguiya at a Mauritel agency once you have been biometrically registered, and monthly data passes start at 200 ouguiya. Two things matter more than price here. First, the inhabited country is a thin string of towns along the coast, the Route de l'Espoir and the oases of the Adrar, with hundreds of kilometres of empty Sahara between them, and no plan from anyone covers the gaps. Second, the government has cut mobile internet nationwide more than once, most recently for over three weeks in 2024, and an eSIM is just as dark as a local SIM when that happens.

Quick Pick: the Best eSIM for Mauritania

Nomad (Mauritania 3 GB / 30 days): At 19 dollars this is the best balance in the only big-brand catalogue that sells Mauritania. It lands on Mauritel, the network with the widest reach, it lasts a month, and it spares you the biometric registration queue on your first day in Nouakchott. Add a local Mauritel line if you are staying long or need a number drivers can ring.

Nomad Mauritania Plans

Nomad is the only one of the three brands we track with a product page for Mauritania, and the catalogue is short and readable: 1 GB over seven days for 9 dollars, 3 GB over thirty days for 19 dollars, 5 GB over thirty days for 29 dollars and 10 GB over thirty days for 49 dollars. The per-gigabyte rate falls from 9 dollars on the smallest plan to 4.90 on the largest, and the 3 GB tier at 6.33 dollars a gigabyte is the sensible middle for a two-week trip that spends evenings on hotel WiFi.

The plan data on the page attaches every package to a single network, Mauritel, on 4G. Elsewhere the same page carries Nomad's standard paragraph about switching between several local networks for 4G and 5G coverage; for Mauritania that is boilerplate, since the plan records list only Mauritel and only 4G. Being on Mauritel is not a bad draw. It is the incumbent, it held a little over half the market at the last published count, and its towers are the ones most likely to be standing in a desert town.

What Nomad does not change is the national picture. Your data still crosses the same Mauritanian network as everyone else's, so an order to cut mobile internet reaches a Nomad profile exactly as it reaches a local SIM. And in the Adrar or on the ore line, the limiting factor is the absence of masts, not which reseller sold you access to them. Buy it for a working connection from the moment you clear the airport at Nouakchott, and for the paperwork you skip, not as a promise of coverage the country does not have.

Mobile Networks in Mauritania

Mauritania has three mobile operators, which surprises people who expect a desert state of four and a half million to have one. Moov Mauritel is the incumbent, part of the Maroc Telecom group and the network every Nomad plan connects to. Mattel, the Mauritano-Tunisian operator, was the first private entrant, and Chinguitel arrived later with Sudanese backing. Mauritel held about 52 percent of the market in September 2023, the most recent figure we found, and it advertises three consecutive years at the top of the nPerf ranking for 4G quality in the country. It has also signed the regulator's specification for a 5G licence, but a visitor should plan on 4G in the larger towns and 2G or nothing beyond them.

What registration actually involves. Mauritel's own instructions for a new prepaid line are short and strict: go to an agency or approved point of sale with your identity document, have the subscription identified biometrically, pay 50 ouguiya, and make a first call within 24 hours or the line is not activated. Mauritel will also put a voice and data line onto an eSIM, through the same agency visit with your passport and the same 50 ouguiya fee. That local eSIM is the answer if your phone has no SIM tray but you still want local rates. It is not something you can buy from abroad.

What local data costs. Mauritel sells data in passes off your main credit, with day passes from 10 ouguiya, week passes from 75 and month passes from 200, plus Grati bundles activated with a recharge code. At roughly 40 ouguiya to the dollar, a month pass starts around 5 dollars. Mauritel's site lists the starting prices but not the data volume attached to each tier, so we cannot quote a verified price per gigabyte, and you should ask at the counter what each pass includes. Even allowing for that, the local route is clearly cheaper than Nomad's 19 dollars for 3 GB. The eSIM wins on time and paperwork, not on price.

Coverage where travelers actually go:

How to Choose the Right Plan

With one big-brand seller the decision is less about which plan and more about how much of the trip the eSIM should carry. Work through it like this.

Get the visa sorted first, because it governs the arrival. Since 5 January 2025 every visa-required nationality has had to apply online through the national registry agency's e-visa portal before boarding, and the old visa on arrival at Nouakchott is gone. Approval usually takes a few working days, and the fee and biometric capture are handled when you land. That last step is the reason to land with data already working: you are fingerprinted at immigration and then, if you want a local SIM, fingerprinted again at a Mauritel agency in town. Installing Nomad at home turns that second queue into an optional errand.

For a short trip, buy Nomad and stop there. A week split between Nouakchott, Nouadhibou and one night in the Banc d'Arguin is covered by the 1 GB plan at 9 dollars if hotel WiFi handles the heavy lifting, or by 3 GB at 19 dollars if it does not. Neither will help in the empty stretches, and nothing else will either.

For longer stays, or work, add a Mauritel line. Anyone spending a month on a mining contract in Zouerat, a fisheries project in Nouadhibou or an NGO posting in the south needs a +222 number for drivers, fixers and offices, and local passes are cheaper over a month. Make the agency visit in Nouakchott or Nouadhibou with your passport, register, pay 50 ouguiya, and make the first call the same day. Mattel or Chinguitel are reasonable second lines if your colleagues are on them, since calls within a network are often cheaper.

Plan the Adrar as offline. Atar is the gateway, and it has at times had seasonal charter flights from France. From there Chinguetti, Ouadane and Terjit are each a few hours by 4x4 over terrain with no masts. Save offline maps of the whole region, carry your guide's and your guesthouse's numbers on paper, and agree a check-in time with someone at home rather than promising to message from the dunes.

Build a shutdown plan for sensitive dates. Election periods and the baccalaureate exam window, usually in summer, are the dates when mobile data has been cut. If your trip overlaps either, choose hotels with fixed-line WiFi, keep important documents offline, and make sure anything urgent can reach you by SMS or a voice call, since the recorded cuts have been aimed at mobile data.

Skip Airalo unless Mauritania is one stop of several. Its Africa regional pack lists Mauritania, but 11 dollars for 1 GB over three days or 41 dollars for 5 GB over thirty is more than Nomad's local plans. It only earns its place on an overland trip that also covers Senegal, Mali or the Gambia.

Frequently Asked Questions

Which network does the Nomad Mauritania eSIM connect to?

Mauritel, on 4G. The plan records on Nomad's Mauritania page list Mauritel as the only network for all four packages. The page also carries Nomad's generic paragraph about switching between several local networks with 4G and 5G, but that text is shared across countries and does not match the plan data. Mauritel is the incumbent and the largest operator, so it is the network you would most want anyway, particularly outside Nouakchott.

Can I get any signal riding the iron-ore train?

Only near the ends and at the occasional station. The line runs 704 km from the mines at Zouerat to Nouadhibou on the coast, through Choum, and the stretch in between is open Sahara. Most travellers board at Choum, ride overnight on top of an ore wagon or in the occasional passenger car, and arrive in Nouadhibou at dawn. Treat the night as offline: download maps, carry water and a scarf, and tell someone when you expect to arrive. The trains can run 3 km long, so a signal at the locomotive does not mean one at your wagon.

Does an eSIM keep working if the government shuts down mobile internet?

No. A Nomad plan runs over Mauritel's network, so when the authorities order operators to cut mobile data, as they did for about 23 days after the 2024 presidential election and during baccalaureate exams in several years, the eSIM goes dark along with every local line. Fixed-line connections, which means most hotel WiFi, have been the usual fallback. If your dates overlap an election or the exam period, plan around WiFi and SMS rather than mobile data.

Will my Senegalese SIM work when I cross at Rosso?

Near the river, possibly, because Senegalese networks spill across it. Once you are inside Mauritania it will be roaming, which depends entirely on your Senegalese operator's agreements and prices, and it stops being an option as soon as you head north toward Nouakchott. If you are coming overland from Saint-Louis, a Nomad plan installed before the crossing is the tidy answer, and our Senegal eSIM guide covers the other side of the border.

Is a local Mauritel SIM worth the registration hassle?

For a stay longer than about two weeks, or if you need a local number, yes. Mauritel's process is an agency visit with your passport, biometric identification, a 50 ouguiya fee and a first call within 24 hours. Month data passes start at 200 ouguiya, roughly 5 dollars, though Mauritel does not publish the data allowance on its site so you will have to ask what each pass includes. For a week of travel, Nomad's 9 or 19 dollar plans save you the queue and the fingerprints.

Do I need the e-visa before I fly, and does it change anything for my phone?

Yes, you need it before boarding. Visa on arrival ended on 5 January 2025, and visa-required travellers now apply online in advance, with the fee and biometrics taken at the airport. For connectivity the change is indirect: the e-visa approval, booking confirmations and hotel addresses should all be saved on the phone as files, because immigration at Nouakchott-Oumtounsy comes before any chance to buy a SIM, and a working eSIM at that desk is a genuine comfort.
