eSIM4Travel does not provide an unlimited‑data eSIM for Cuba. The only plans listed for the destination are fixed data bundles with caps of 3GB or 1GB and specific validity periods of 30 days, 7 days, or 1 day. Because none of the plans have a data cap labeled “unlimited, ” an unlimited data option is not available.
For travelers who need a larger data allowance, fixed‑data plans such as the 3GB/30Days plan priced at $57.34 USD or the 1GB/7Days plan priced at $17.10 USD are available. These bundles can be more cost‑effective for most users, though they may require additional purchases for extremely heavy data consumption.
