eSIM Firsty pour Poland en 2026

Firsty has not published which operators it uses in Poland, so the radio side is unknown rather than bad; the table above is where the stated allowances and validity can be checked. It has also not stated where traffic breaks out, leaving local delay and the IP location uncertain. The large range makes sizing the real decision, with the risk of buying more data than a fortnight needs. Firsty lists 5G as the ceiling and confirms top-up, so an exhausted plan can be extended rather than automatically rebought.
