No, yaySIM does not provide an unlimited data eSIM for Cape Verde. All of the plans listed for Cape Verde have a fixed data cap, ranging from 3GB to 20GB, and each plan has a specified validity period.
Travelers who need a large amount of data can choose from the fixed data plans that are available. For example, the CV_20_30 plan offers 20GB for 30 days, while the CV_10_30 plan provides 10GB for 30 days. These fixed data plans can be more cost‑effective for most users, unless the traveler is an extremely heavy data consumer who would prefer an unlimited option.
