eSIM‑On Shop does not offer an unlimited data eSIM for Poland. The provider’s catalogue for this destination consists of fixed data plans with caps ranging from 5GB to 50GB and validity periods between 15 and 180 days.
For instance, the 50GB plan is valid for 180 days and is priced at $70.00 USD, while a 20GB plan is available for 30 days at $20.50 USD. Choosing a fixed data plan can be more cost‑effective for most travelers unless an extremely heavy data consumer requires a truly unlimited option.
