Soovia eSIM does not offer a plan with unlimited data for Poland. The only options available provide a hard cap, such as the Europe 100GB 180‑day plan or the Poland 50GB 180‑day plan, each with a specified data allowance and validity period.
For travelers who need a large amount of data, these fixed data plans are the available choice. Choosing a fixed data plan can be more cost‑effective unless a user expects to consume data far beyond the cap, in which case a Pay‑as‑you‑go approach might be better, though such a plan is not listed for Poland.
