WonderConnect does not provide an unlimited data eSIM for Mauritania. All plans listed for the country have a defined data cap, the largest being 10GB for a validity period of 30 days.
The provider offers several fixed data options that may suit most travelers, such as a 10GB plan for 30 days, priced at $139.99 USD, and a 5GB plan for 30 days, priced at $79.99 USD. These plans include tethering and are valid for the stated period, which can be a more cost‑effective choice unless an extremely high data consumption is expected.
