Hello, Czech,

I have a question for anyone from Poland here. I will Go with my Family for The next four Weeks to Cracow and Zakopane, and i still have a Fee Nano SIM Slot in my Smartphone that i would like to fill with Prepaid mobile Internet from a polish Phone company. I would like to Surf the Forum here and browse YouTube. Any recommendation what company has the best Network and prices for a few GB per day? Orange? Play?
Any advice is Welcome. Thank you!
