Thumbs down [Q] Data not working.

Hi all, thanks a lot to read the thread and try to help.
The thing is that even I haven't install anything nor updating any room, I have a real problem lately.
If I use WiFi my HTC works fine, but when I disconnect WiFi, even a data logo appears (H or 3G) nothing that uses data works.
I cannot use Whatsapp, Facebook even open Google on a new tab.
The arrows keep moving on my status bar, but I downloaded a data monitor and says that nothing is moving in data usage.
What can I do before I lose WiFi?
I have restored the mobile phone, a complete wipe, i'll write you soon.
