How much data do I need for a Poland trip, and can I tether?

For a typical 3 to 5-day Krakow city break, the 5 GB plan is enough for most travelers. A 7 to 10-day trip combining Warsaw, Krakow, and Gdansk with daily Google Maps, Bolt rides, and casual photo uploads usually needs 10 GB to 25 GB. The 50 GB plan suits heavy users on extended stays, digital nomads working from Warsaw co-working spaces, or families sharing one connection. Hotspot and tethering are explicitly allowed on all ETravelSim Poland plans including the 50 GB tier — useful for sharing data with a laptop or another phone.
