Wiiline does not provide a truly unlimited data eSIM for Cuba. The plans that carry “Unlimited” in the name offer a hard data cap each day or for the entire validity period; once the limit is reached the speed falls to the stated reduced rate (e.g., 512kbps or 2000kbps).
Travelers who need a larger, uninterrupted data allowance can opt for fixed‑data plans, such as 50GB for 30 days, 20GB for 30 days, or 10GB for 30 days. These plans grant a clear amount of data that must be consumed within the validity period and may be more cost‑effective for most users.
