Stellar eSim does not offer a true unlimited data plan for Poland. All of the Poland‑specific plans listed have a fixed data cap, with the largest capped allowance being 3GB on the plans that carry the “Unlimited” name; after that amount is used, data is either throttled or the speed is lowered if a reduced speed is specified.
For travellers who need more data, Stellar eSim provides fixed‑data plans that allow 3GB for periods ranging from 1 day to 60 days, or higher‑cap options such as 50GB or 100GB bundles that are valid for 30 to 180 days. These alternatives still have hard limits, but they offer larger data allowances compared to the 3GB “Unlimited” plans.
