Travel / Mobile internet for tourists in Poland? [35]

I am here in Poland right now. I rented router from polishwifi.

It's works really well. I started my trip in Cracow, then I visited Oswiecim and now I'm finishing journey in Warsaw. Everywhere I had good coverage, I used mostly Google maps, towns websites, email and social media. They send mi pocket with router to my first hotel in Cracow, and now I have to send it back to company.So far I recommend Polish Wifi, comfort of being connected with everything and everybody is incredible.

P.S Being in Poland You have to try polish "pierogi" I could eat it every day! :D
