No, yaySIM does not provide an unlimited data eSIM for Benin. All of the plans listed for Benin have a specific data cap, such as 20GB, 10GB, 5GB, or 3GB, and each plan has a defined validity period ranging from 1 day to 30 days.
Travelers who need a larger data allowance can choose from fixed data plans. For example, the BJ_20_30 plan offers 20GB of data for 30 days, and the BJ_10_30 plan provides 10GB for 30 days. These fixed data plans can be more cost‑effective for most users unless they are extremely heavy data consumers.
