No, eSIMX does not provide an unlimited data eSIM for Poland. The provider’s available plans for Poland have fixed data caps of 30GB, 50GB, or 100GB and a validity of 7 days or 30 days. Travelers who need more data can choose a fixed data plan such as the Poland 30GB 7Days or the Europe 100GB 30Days With Calls, which offer large data allowances and may be more cost‑effective for most users unless they are extremely heavy data consumers.
