EZsim does not have an unlimited data eSIM for Poland. The plans it offers for Poland are fixed‑data bundles, each with a hard data cap and a defined validity period. The available bundles range from 1GB for 7 days to 20GB for 30 days, with the 20GB/30‑day option being the largest single bundle.
Fixed‑data plans provide a predictable expense and can be more cost‑effective for most travelers, but they limit the amount of high‑speed data that can be used within the validity window. For users who anticipate very high data consumption, an unlimited plan would be necessary, but such a plan is not offered by EZsim in Poland.
