Hi, I recently sent my Xperia Z3 to Sony Service Centre @ 313 Somerset and when i got it back, i noticed the VoLTE feature missing. I guess this must a firmware/software issue. I was told to check with SIngtel and to my frustration (2 visits in total) Singtel said they are not responsible for updating firmware and asked me to check with Sony Service Centre again. On returning back to Sony Service Centre @ 313 Somerset, I was told by another staff that they are aware of the issue and could only update the firmware when they received it (from where i do not know). The funny thing is that if the fulfillment centre of the Xperia Z3 product for SIngtel can load the Xperia Z3 with the firmware that supports VoLTE, why hasn't Sony Service Centre in Singapore received that firmware at all? And it was a pity that i forgot to note the firmware version when i just bought it from Singtel. I wonder which firmware version that is (that supports VoLTE)?

Hi, I was scratching my heads when i see a special LTE-related status icon on my xperia Z3. After reading above thread it became apparent it can be disabled/enabled and is also requires carrier support. Mine is Singtel and it is marketed as "ClearVoice": http://info.singtel.com/personal/4G/4Gclearvoice I guess more importantly is though it does not charge customers for this service as of now, there is always a potential of charging this service depending on carrier and its policy.
