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.

Allow for messages and occasional map checks, then add uploads and every phone or laptop sharing the plan allowance.
Whole-stay validity

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.

In total, a 5 GB data allowance covers roughly 1,700 shared photos, 83 hours of social media and browsing, 15 hours of video calls, 63 hours of music streaming, or about 1000 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 fly →Nouadhibou · 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 fly →Atar 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 fly →Why 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
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.
