Rebooting when Mobile Data is active

[Ronafios]

My Xperia Z ultra is rebooting under the following conditions:

- Mobile data is enabled

- No wifi network is available (or wifi is off)

- Phone goes in to standby (e.g. you press the power button or it times out)

I've tried a SIM card from Optus, Telstra and Vodafone and it reboots every single time!  No reboot if I disable mobile data.  Any suggestions?

I have a Mac - I had already installed Bridge and I performed a complete repair already.  It hasn't made any difference.  Factory reset, repair through Sony Bridge - as soon as I enable mobile data, the phone reboots when it enters standby.

Unfortunately in this case it appears you may have a hardware issue and as such I would have to advise you to return the phone so that it may be assessed by an authorised repair agent sorry.
