4S eSIM eSIM Data Plans for Mauritania

4S eSIM does not provide a truly unlimited data eSIM for Mauritania. All plans that carry “Unlimited” in their name actually include a fixed data cap—ranging from 3GB to 30GB—and specify a reduced speed of 1000 kbps after the cap is reached. Travelers who need more than the allotted high‑speed data may use the standard fixed‑data plans instead. Two examples of these large‑data plans are the 30GB package valid for 15 or 30 days and the 20GB package valid for 5, 7, or 15 days. Choosing a fixed‑data plan can be more economical unless very heavy data consumption is expected.

4S eSIM does not provide a Mauritania eSIM plan that includes a local phone number or SMS capability. The only options available from this provider for Mauritania are data‑only eSIM plans.

Travelers who need to communicate can generally use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these apps are accessible in Mauritania before purchasing. Some destinations may block or restrict certain VoIP services, so it is advisable to confirm compatibility with the specific messaging apps you rely on.

4S eSIM offers 37 single‑country data plans for Mauritania, with no multi‑country options available. These plans split into 6 daily data cap offerings and 31 fixed‑data‑cap plans. Prices run from about $8.34 to $233.83, while data limits vary between 714 MB and 30 GB.
