WonderConnect does not have a plan that provides unlimited data for Poland. The provider offers fixed data plans, the largest of which give a 50‑GB allowance for 30 days at a price of $33.49 USD, and another 20‑GB plan for $18.99 USD. Because these plans are data‑limited, they can be more cost‑effective for travelers who do not need heavy data usage, while those who consume a very large amount of data may need to purchase additional credit or consider a different solution.
