VoLTE Xperia Z2 D6503

Hi!

Does the Xperia Z2 support VoLTE? (Network supports VoLTE and the contract allows it)

If I dial any number, it switches me back to 3G then.

@marcel45

Have you contacted your carrier/network regarding this?

[marcel45]

Yes, I did. They told me to ask Sony. .... did it, Sony recommended me to email Xperia care.... did it too, No answer for VoLTE.... Phoned Sony again, phone call cut off (faulty Sony Phonesystem network). Nothing at all was helpful.

@marcel45

Is your phone locked to a carrier/network branded?

[marcel45]

Yup

The Z2 does support VoLTE but it has to be implemented (Software wise)

It'll be up to them, your carrier, to add this feature to their update > test it > approve it > release it.

Sorry, but even the net carrier said, it is up to Sony. Even the Z3  Supports it. Btw one website says yes it is VoLTE capable, the next says no........ etc

A carrier trying to say it's not up to them nor their problem nor their fault, that's unheard of lol, the carrier has to allow this on their software variant.

Another question, does att support it on the Z2?
