eSIMsData does not provide any plan with a true unlimited data allowance for Mauritania; all data caps listed in the provider’s table are finite. The available options for travelers include fixed‑data plans such as 10GB for 30 days or 5GB for 30 days, offering a set amount of high‑speed data that must be used within the plan’s validity period.
Plans that carry “Unlimited” in their names are actually limited to a daily high‑speed allowance—1 GB/day or 2 GB/day—and after that threshold the speed is reduced to 1250 kbps or 2000 kbps respectively. Choosing one of the fixed‑data plans can therefore be more cost‑effective for most users, unless a traveler requires a very high volume of data in a short time.
