ZenSim does not provide a true unlimited data eSIM for Poland. All plans listed for Poland are capped, with the highest high‑speed allocation being 3 GB per day on the “Poland Unlimited STANDARD” options. After the daily allowance is exceeded, the connection speed is lowered, although the exact throttled rate is not specified in the available information.
For travelers wanting a larger data pool, ZenSim offers fixed‑data alternatives that may be more economical. For example, the 20 GB plans are available for both 10‑day and 30‑day validity periods, and a 10 GB plan lasts 10 days. These plans provide a larger total data allowance than the daily caps and can be more cost‑effective for users who are heavy internet consumers but do not need unlimited usage.
