Simbye does not provide a truly unlimited high‑speed eSIM plan for Poland. The plans labeled “Unlimited” are fixed‑data offerings that allow 2 GB per day at full speed; once that daily cap is reached the speed is reduced to 1 Mbps.
Travelers who need more data can choose fixed‑data plans instead. For example, Simbye offers a 20 GB plan valid for 30 days, as well as 50 GB and 100 GB options that are valid for 30 days and support tethering. These fixed plans provide larger data allowances without the speed reduction that accompanies the “Unlimited” plans.
