Yes, Truely offers unlimited data eSIM plans that are valid for use in Poland. The plans are available in a range of validity periods from 1 day to 30 days, with prices ranging from $5.52 USD for a 1‑day plan to $74.93 USD for a 30‑day plan. Each plan is valid for 3G, 4G and 5G networks across the entire country.
Although the data allowance is unlimited, Truely’s plans may be subject to a fair‑usage policy that can throttle speeds after heavy use. Normal speed is typically capped at the network’s maximum speed before throttling begins. If you need further details about the fair‑usage limits or the amount of data that can be used at standard speed, you should contact Truely directly for confirmation.
