airdatalink does not have an unlimited data eSIM for Poland. The plans that airdatalink offers for Poland are fixed data bundles, such as the Poland eSIM — 50 GB · 180 days or the Europe 49 eSIM — 50 GB · 15 days, which provide a hard limit of 50 GB that must be used within the specified validity period.
For travelers who need more data, airdatalink offers larger fixed bundles, for example the Europe 49 eSIM — 50 GB · 30 days and the Europe & United States 54 eSIM — 50 GB · 30 days, both delivering 50 GB on a 30‑day validity. Choosing a fixed data plan can be more cost‑effective for most users, unless a very heavy data user prefers the flexibility of a pay‑as‑you‑go model.
