simpleSIM does not provide a truly unlimited data eSIM for Poland. All of the plans listed for Poland have a hard data cap; the “Unlimited” label in the plan names refers to unlimited calls and texts, not to unlimited high‑speed data. The largest data allowance available is 50GB for 30 days, and there are also 20GB plans for 30 days.
Travelers who need a large amount of data can choose a fixed data plan such as the 20GB plan for 30 days or the 50GB plan for 30 days. These plans offer a substantial amount of high‑speed data and may be more cost‑effective than a plan that limits data to 1GB per day.
