ZenSim does not provide a truly unlimited high‑speed data plan for Italy. The plans that carry the label “Unlimited” actually include a cap of 3 GB per day; after the allocated data is used the speed is reduced, although the exact throttled speed is not listed. Because of this limitation, these plans are not equivalent to an unlimited data eSIM.
Travelers who need more data at a fixed cost can choose one of ZenSim’s fixed‑data plans instead. For example, the Italy 20 GB plan is sold for 10 days or 30 days, and the Italy 10 GB plan is available for 10 days. These options give higher total data allowances, and can be more economical for users who consume large amounts of data during their trip. The examples above are only a subset of the available ZenSim plans for Italy.
