4S eSIM eSIM Data Plans for Cuba

4S eSIM does not provide a genuinely unlimited high‑speed data eSIM for Cuba. The plans that include “Unlimited” in their names actually contain a fixed data allowance—3GB, 5GB, or 10GB—which is replenished over the validity period (for example, 3 GB for 1 day or 5 GB for 5 days). Once the capped amount has been used, the speed is reduced to 1 000 kbps.

Travelers can select from a variety of fixed‑data plans as alternatives. For example, 4S eSIM offers a 10 GB plan that can be bought for 5 days, 7 days, 15 days, 30 days, or 90 days. Similar mid‑range options are available for 3 GB and 5 GB. Choosing one of these fixed‑data plans often provides better cost efficiency for most users unless extremely heavy data consumption is expected.

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.
