VoLTE

Will the XZ support VoLTE on T-Mobile? I understand that Sony had to go through the certification process with T-Mobile but if HTC and other OEMs can do it why can't Sony?

Re: VoLTE

This is something that the network has to enable, in other words, it won't work with unlocked devices

Re: VoLTE

No it is not. There are several unlocked devices on the market that support VoLTE on T-Mobile. A device maker has to certify the VoLTE function of the phone with T-Mobile.

Re: VoLTE

Again, it is up to T-mobile NOT Sony.

However band support is not the only requirement.

"Every OEM has the option to support VoLTE and E911 or not," T-Mobile said. "It's their decision, though obviously, we hope that every OEM will choose to support these features and get certified on our network."

 

 

It'll be wise to check T-mobile's official forum

Your Xperia DOES support VoLTE, BUT it is not supported by your carrier. If T-mobile doesn't carry this device, it's unlikely that they will invest time and money on customizing an update that will enable this.

Re: VoLTE

It is all up to Sony and not T-Mobile. Sony doesn't want to spend any money on getting the XZ certified to work on T-Mobile.
You even posted thay in your links.

Re: VoLTE

You can use the search bar above, there is info on how the updates are released, once Sony or any OEM finish an update > it has to be approved by region/country > for VoLTE it has to be test it > customized > approved by the carrier network, you should post this on the T-mobile forum, perhaps someone from T-mobile staff can give you an official statement on this.

Re: VoLTE

Bingo, like you said it has to be tested and approved but Sony doesn't want to pay for testing and approval. VoLTE stands are not the same in every country because the global standard has not been set. Even if a phone is VoLTE ready it doesn't mean that it will work fine on all networks.

Re: VoLTE

You took it out of context, this testing is on the carrier/network, post on their forum and/or contact them.
