Yes, Earth Esim sells several unlimited data eSIM plans that cover Poland. The plans range from a 1‑day option costing $1.49 USD to a 60‑day option costing $59.99 USD, with validity periods of 1 day, 3 days, 5 days, 7 days, 10 days, 15 days, 20 days, 25 days, 30 days and 60 days available. All of these plans carry an unlimited data cap on the network and allow tethering, but speeds may be throttled after heavy usage under a Fair Usage Policy; the maximum speed is typically capped at 1000kbps, with some longer‑term plans offering up to 5000kbps or 10000kbps. If speed restrictions are a concern, travelers can contact Earth Esim to confirm the typical volume of data that remains at normal speed.
