just got an XZU c6833 and put my tmobile sim in it. everthing seems to work fine except mms. I have tried multiple times to go to mobile networks and download the internet & MMS settings but pics still wont send or receive. i also tried go sms to see if it was the stock sony app.
not rooted, no custom roms, no unlocked bootloader
