4S eSIM eSIM Data Plans for Cuba

4S eSIM does not provide a true unlimited high‑speed data eSIM for Cuba. The plans listed as “Unlimited” are fixed‑data plans that offer a set amount of data—3 GB, 5 GB, or 10 GB—and after that amount the speed is throttled to 1000 kbps. A real unlimited plan, where data can be used without restriction, is not available.

Travelers who need a larger, fixed allocation can choose from the non‑Unlimited options among the Cuban plans. For example, a 10 GB plan is available for 5, 7, 15, 30, or 90 days, providing a consistent data allowance at full speed throughout the validity period. These fixed data plans are usually more cost‑effective for users who can plan their data use within the given period.

4S eSIM does not provide an eSIM for Cuba that includes a phone number or SMS capability. Travelers can only purchase data‑only eSIMs from this provider. They may still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages, but some destinations can block or restrict access to these apps. Travelers should confirm that the apps they need are available in Cuba before buying a plan.

4S eSIM has 26 single‑country data plans available for Cuba and does not offer any multi‑country plans there. These plans vary in duration from 1 to 365 days and differ in whether they provide a fixed data allowance or a daily data cap. The overall price range for the available Cuba plans spans from roughly $16.76 to $235.79, while the data caps offered fall between 714 MB and 10 GB.
