The short answer
This is Mauritania in West Africa, on the Sahara and the Atlantic, not Mauritius in the Indian Ocean, which has its own comparison at /blog/best-esim-for-mauritius. Six travel eSIMs get most of the traffic for this search, and five of them sell data for Mauritania. I priced them on the same day, for a few days in Nouakchott, two weeks in the Adrar and a month, and I read the fine print. In Mauritania Ringo Light is far from the cheapest, and I say plainly who is.
Unlimited data at full speed for 2 weeks at $106.99 or 30 days at $211.99, nothing renews. It is expensive: Ubigi's Best World plan gives 30 GB at full speed for 15 days at $77, $29.99 less, and 60 GB for 30 days at $99, $112.99 less.
On Mattel. Its Best World plan sells 10 GB for 30 days at $39, 30 GB for 15 days at $77 and 60 GB for 30 days at $99, then 2 Mbps. Its own Mauritania plans stop at 3 GB.
1 GB for 7 days at $9, 3 GB for 30 days at $15 and 10 GB for 30 days at $35, all Mauritania plans on Mauritel 4G.
No Mauritania plan of its own; its Hello Africa regional plan covers it, from 1 GB for 3 days at $11 to 5 GB for 30 days at $41, on Mauritel.
Prices read on 11 November 2026: Airalo, Holafly, Saily, Nomad, Ubigi on their own sites or listings, Ringo Light from its catalogue. All in US dollars unless stated. Treat every number as a snapshot.

That is the full Ringo service: one plan that works everywhere, with your own number included.
It is a separate product from Ringo Light and it is still being built, so it is not on sale yet. Join the waitlist to hear when it opens.
What to do in Mauritania, and what your phone needs for it
Eight places most first trips include, from the fishing beach of Nouakchott and the Banc d'Arguin to the old desert towns of the Adrar, the Eye of the Sahara, the iron ore train and Nouadhibou, with the one thing your data does for you at each. Distances are long and signal is thin between towns, so offline maps matter more here than almost anywhere. Before you go, check your government's travel advice.
If you want unlimited: Ringo Light is the only true one, and it is expensive
Most Mauritania trips run one to two weeks: a day or two in Nouakchott, then north to Atar and the old towns of the Adrar, sometimes the iron ore train and the coast at Nouadhibou. None of the rivals sells unlimited data for Mauritania. The closest is Ubigi's Best World plan: 30 GB at full speed for 15 days at $77, or 60 GB for 30 days at $99, then 2 Mbps. Ringo Light charges $106.99 for 2 weeks and $211.99 for 30 days, nothing renews.
So Ringo Light loses both lengths. Ubigi is $29.99 cheaper for two weeks and $112.99 cheaper for a month, with three times the starting data. Nomad sells 10 GB for 30 days at $35 and Ubigi 10 GB at $39, which is enough for maps, messages and photos home on most trips. I would buy one of those, and I would rather you read that here than at checkout.
Ringo Light is unlimited data at full speed for the whole trip. For a short trip, Ringo Light sells no 3-day plan and its 7 days is $78.99; Nomad sells 1 GB for 7 days at $9.
Mauritel, Mattel, and the empty Sahara
Mauritania has three mobile networks: Mauritel, Mattel and Chinguitel. Airalo and Nomad name Mauritel, Ubigi names Mattel. In Nouakchott, Nouadhibou, Atar and along the main roads you get 4G or 3G. Between towns the country is mostly desert, and signal can be gone for hours on the road to Chinguetti and Ouadane, on the iron ore train and in the Banc d'Arguin. I would save offline maps before leaving a town, whichever eSIM you buy.
If you want a data bucket: Nomad or Ubigi
- Nomad, $35 for 10 GB. For 30 days on Mauritel 4G. Smaller sizes: 1 GB for 7 days at $9, 3 GB for 30 days at $15, 5 GB for 30 days at $25. The cheapest Mauritania plans of their own.
- Ubigi, $39 for 10 GB. On its Best World plan, 30 days, on Mattel. Its own Mauritania plans are small: 1 GB for 7 days at $12, 3 GB for 15 days at $24. 20 GB a month on its World plan is $44, and it renews.
- Airalo, $41 for 5 GB. For 30 days on its Hello Africa regional plan, on Mauritel; 5 GB for 15 days is $37. No 10 GB for Mauritania. The app is needed.
- Saily, $19.99 for 1 GB. For 7 days, its only Mauritania plan. Its esimdb listing is from 6 October; saily.com refused the fetch.
- ✓Ringo Light, no buckets. Ringo Light sells 2 weeks of unlimited for $106.99 and 30 days of unlimited for $211.99. For a fixed amount of data, Nomad and Ubigi are far cheaper in Mauritania. I would buy Ringo Light only if you want unlimited with no speed cap and are happy to pay for it.
What Ringo Light is
Ringo Light is the data eSIM Ringo sells to fund the full Ringo, one plan that works everywhere with your own number ported onto it. I write for Ringo, so weigh that. For Mauritania it sells three trips, all unlimited data at full speed with no speed cap: 7 days at $78.99, 2 weeks at $106.99 and 30 days at $211.99. Nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.
In Mauritania the Ringo Light prices are high. I would pick Ubigi's 30 GB for 15 days at $77 or Nomad's 10 GB for 30 days at $35 for most visitors. No regional Ringo Light trip covers Mauritania, so there is no cheaper Ringo Light route in.
The card to buy it is further up this page, just after the side-by-side table.
Pick by trip
Nomad, 1 GB for 7 days at $9, or 3 GB for 30 days at $15. Ringo Light sells no 3 days.
Nomad, 10 GB for 30 days at $35 on Mauritel, or Ubigi Best World 10 GB at $39.
Ubigi Best World, 30 GB at full speed for 15 days at $77, then 2 Mbps. Ringo Light's 2 weeks at $106.99 if you want unlimited data at full speed.
Ubigi Best World, 60 GB for 30 days at $99. Ringo Light's 30 days is $211.99.
Ringo Light, 2 weeks at $106.99 or 30 days at $211.99, the eSIM by email. The only plan of the six with no speed cap.
None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
Frequently asked questions
How we compared, and our sources
Airalo, Holafly, Saily, Nomad, Ubigi, Ringo Light
We priced Airalo, Saily, Nomad, Ubigi and Ringo Light for Mauritania on 11 November 2026, all on the same day, in US dollars. Each rival's price comes from its own website where it showed dollars, otherwise from an esimdb.com listing, and every source and its date is listed below. Ringo Light's prices come from the catalogue our checkout charges.
We compare the trips people actually book: a week, two weeks and a month of unlimited data, and a 10 GB bucket. We read each brand's fair use and speed rules and quote them as the brands state them. We did not run speed tests, so this page makes no speed claims for any brand.
Ringo Light is our own product. We put it in the table on the same terms as everyone else, and where a rival is the better buy the page says so.
Left out: Holafly. It has no Mauritania page on esim.holafly.com, no esimdb.com listing, and Mauritania is not in its Africa or Global plans, so there is nothing to compare. Left out: Maya Mobile. I compared the brands that get most of the traffic for this search and did not price Maya Mobile on the day.
