Can't Download using Mobile Data

Hello everybody,
I have bough a Meizu M3 Note in China, even though I am in Italy and I am using an Italian career right now. Everything works except for download when using mobile data. Whit download I refer to Google Play apps and files from browser, I have not any synchronization-related problem.

Can Somebody help me? Thanks in advance.

open default download manager app the one with green circle and accept mobile data ( prompt message )
