Phone [Q] Why data networks from my Moto G does not work?

Hello, I want to know why my Moto G XT1032 Brazil performs and receives calls. Receives but does not send SMS and no data network work or is not detected ... Networks such as EDGE, 3G ... I'll tell you everything I did in Moto G since I bought for you to understand: First, I installed the ROM of the United Kingdom 4.3 so I can upgrade to KITKAT, after a time my data networks stopped working, then installed the ROM from Germany and to no avail. I went back to stock 4.3 ROM from Brazil, today I made the upgrade to the KitKat and still no data network. How do I get my network back up and running? (Sorry for the english, i'm brazilian, translated in google translate)
