Qrispy eSIM does not provide an unlimited data eSIM plan for Poland. Its offers for Poland are all pay‑as‑you‑go data credit, with the largest available package being the Poland 10GB plan (about 10 GB of data at the current rate) and a Poland 5GB plan (roughly 5 GB). Each plan can be topped up at any time and the credit does not expire, so unused data remains available for future use.
Pay‑as‑you‑go data credit can be more cost‑effective than an unlimited plan unless the traveler is an extremely heavy data user, because the user pays only for the data actually consumed and can add additional credit when needed.
