Mobile data is not working after the Sony Android 5.1.1 update

[AjayBoss]

I had updated my T2 Ultra duos to Android 5.1.1 update provided by Sony under phone update option via Wifi. 

Once after the update I am not able to use my mobile data, where as I am able to connect to the internet via Wifi. 

I have a proper micro sim (not the manually cut version)

Is this because of the new s/w update? Am I suppose to go back to factory settings?

Please suggest.

Try performing a system repair using PC Companion as this will often fix issues - This will factory reset your phone and erase all data so best to backup before you begin

Switch off your phone and unplug from Pc (Hold volume up and power for around 10 seconds)
Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the on screen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process

If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP
