Mauritania eSIM for coast and inland plans
Choose mobile data for Nouakchott, a separate Nouadhibou stay or an organised Atar and Adrar visit.
A Mauritania itinerary can stay in Nouakchott, add the Atlantic city of Nouadhibou, or include an arranged inland leg through Atar in the Adrar. Keep each accommodation, host and meeting entrance with the correct stop. For the inland leg, save the guide's meeting point, agreed route and lodging directions offline before leaving the coast.
For this trip
Which eSIM fits a Mauritania trip?
Before buying, compare Horizon’s Mauritania plans by validity for every confirmed day on the coast and inland and by data for messages, occasional map checks, uploads and each device sharing the allowance. Keep Nouakchott, Nouadhibou and an organised Adrar leg as separate trip stages with their exact contacts. Verify Mauritania in the product list, and choose another suitable plan for Morocco, Senegal or any onward country.
Horizon sells the plans shown here. This brief compares those offers for a Mauritania itinerary and is not an independent ranking of the whole eSIM market.
Data for planned tasks
Allow for messages and occasional map checks, then add uploads and every phone or laptop sharing the plan allowance.
Whole-stay validity
Include every night and change day across Nouakchott, Nouadhibou and any organised inland leg.
Countries included
The country plan covers Mauritania only; choose another suitable plan for Morocco, Senegal or any onward country.

How eSIM works in Mauritania
Install the eSIM over reliable Wi-Fi before departure and keep its line off until Mauritania. There, set Horizon as the mobile data line and enable data roaming for it. Check the validity rule before purchase: the period starts with the first successful connection to a supported network in Mauritania. A compatible dual-SIM phone may keep the home SIM active, but its provider may charge for use.
Install your eSIM
Scan the QR or auto-install in the app — no physical SIM.
Land & connect
Data activates on first connection at your destination.
Size it to your trip
Pick the profile closest to your trip. The estimate assumes normal use — maps, messaging, photos, a short call home.
As a rule of thumb, a 3–4 day city break runs on about 1–3 GB, a one-week trip on 3–5 GB, a two-week multi-country tour on 8–12 GB, and working on the road takes about 1 GB a day, so 15 GB or more for two weeks.
Recommended size
3GB3–4 days
≈0.4 GB a day
- Maps every day
- Messaging and photos
- A short call home most days
In total, a 10 GB data allowance covers roughly 3,300 shared photos, 167 hours of social media and browsing, 29 hours of video calls, 125 hours of music streaming, or about 2000 hours of maps and navigation. Messaging apps barely use data.

Important cities in Mauritania
Nouakchott · City guide
Nouakchott
For a Nouakchott stay, save the first accommodation or family address with the actual entrance and arrival contact. Keep office meetings in a separate note with the correct building detail. Include every night in validity and keep the essentials offline before the first meeting.
Nouakchott eSIM — set up before you flyNouadhibou · City guide
Nouadhibou
Treat Nouadhibou as its own coastal-city stay. Store the host, confirmed accommodation and transfer instructions together, rather than mixing them with Nouakchott details. Add its nights and the change day to validity, and save the next meeting point offline.
Nouadhibou eSIM — set up before you flyAtar and the Adrar · City guide
Atar and the Adrar
For an arranged inland visit through Atar, keep the guide's exact meeting point, agreed route and lodging directions offline. Confirm the next contact before departure from the coast and include every inland day in validity. Do not make essential access depend on a connection in the desert.
Atar and the Adrar eSIM — set up before you flyWhy Horizon
Plan each stop separately
Match validity to every day in Mauritania and size data for messages and occasional map checks before adding uploads or shared devices. Hotspot is free on every Horizon plan, uses the plan allowance and is not throttled by Horizon. This is a data-only product with no local number. Horizon offers Mauritania country plans outside its North Africa bundle; Morocco and Senegal need separate suitable plans.

Frequently asked questions
How much do Mauritania eSIM plans cost?
Mauritania eSIM prices start at €5.79 for 1 GB (7 days). The recommended plan, 10 GB (30 days), costs €55.69.
What fits a Nouakchott stay?
Cover every night and compare the current allowance with work messages, documents and occasional map checks. Save the exact first entrance and arrival contact offline.
What changes when I add Nouadhibou?
Add its nights and the day you change cities to validity. Keep the Nouadhibou host, accommodation and transfer instructions together, separate from Nouakchott.
What should I save for an Adrar visit?
For an organised inland leg, save the guide's exact meeting point, agreed route, lodging directions and essential documents offline. Confirm the next contact before leaving the coast.
Can I share data in Mauritania?
Yes. Hotspot with the Mauritania plan is free, and Horizon does not throttle it. A compatible phone is required; the phone and all connected devices share the plan allowance.
Is Mauritania in the North Africa bundle?
No. Horizon offers Mauritania country plans, and Mauritania is outside the North Africa bundle. Choose separate suitable plans for Morocco, Senegal or any other country.
Does the plan promise desert reception?
No. A Mauritania country plan does not promise reception at every inland point. Store guide details, route notes, lodging directions and essential documents offline before an organised Adrar leg.
Can I keep my WhatsApp and phone number with the Mauritania eSIM?
Yes. WhatsApp stays linked to your usual number and runs on the eSIM's data. On a dual-SIM phone, your usual SIM can stay on for ordinary calls and texts. Your home carrier may charge for calls, texts or data on that line, so turn off data roaming there.
Does the Mauritania eSIM include calls and texts?
No. Horizon plans are data-only, with no phone number for calls or texts. Use apps such as WhatsApp or FaceTime over the eSIM's data, or keep your usual SIM on for ordinary calls and texts.
Do I need to turn on data roaming for the Mauritania eSIM?
Yes. A travel eSIM connects to local networks as a roaming line, so turn on data roaming for the Horizon eSIM when you arrive. The plan is prepaid, so Horizon does not bill you after checkout. Keep data roaming off on your usual SIM to avoid charges from your home carrier.
What happens if I run out of data on the Mauritania eSIM?
You can buy more. If your plan supports a top-up, My eSIMs shows the data you can add to the same eSIM. If it does not, buy another Mauritania plan and install it the same way.
Will my phone work with the Mauritania eSIM?
It will if your phone supports eSIM and is not locked to your home carrier. Many recent iPhone and Android models do, but some regional versions do not, so check your exact model on the supported devices page before you buy.
See supported devicesWill Horizon slow down my data?
No. Horizon fixed-data plans have no throttling. There is no daily limit that slows you down, so you can use your whole plan in one day if you need to. Your speed depends on the local network, your signal and how busy the network is. When your data allowance is used up, the plan stops rather than slowing down.
Can I get a refund if I already used some data?
Yes. We always refund the full amount you paid when you request it, whether your eSIM is unused, partly used or fully used. There is no time limit for requesting a refund.
