Dear Piotr, you know when you ahve not possibility to find a better solution, you have to choice the free one...
Now i am back but when i was there, no way to connect to any research engine, only bing was working, but when you wrote VPN in searching place, nothing of useful comes, so only thanks to Teamviewer i managed to connect to my home PC and download the best free VPN, from China even google authenticator do not work, so make payment for me was impossible.
Now i need to find a reliable one which can connect phones and pc, in the third week of february i have to go back there...:(((
