TailSim does not provide an unlimited data eSIM for Poland. All of its Polish plans are fixed data bundles with specified capacities that must be used within a 30‑day validity period.
Travelers looking for large data allowances can choose from TailSim’s fixed plans such as the 50 GB 30‑day bundle for $52.99 USD, the 20 GB 30‑day bundle for $19.99 USD, or the 10 GB 30‑day bundle for $13.99 USD. These plans are generally more cost‑effective for most users and offer 5G coverage within Poland.
