aloSIM does not provide an unlimited data eSIM for Mauritania.
The available options are fixed‑data plans, such as 5 GB for 30 days at $42.00, 3 GB for 15 days at $27.00, 2 GB for 7 days at $19.00, or 1 GB for 7 days at $10.00. Choosing one of these fixed‑data plans can be more cost effective for most travelers, although very heavy data users may need to consider plans with higher data allowances.
