VOLTE?

[kevev]

Does the XA support VOLTE? The whitepaper on Sony Mobile's site states that the device does. But I am on T-Mobile US network and calls drop to UMTS/HSPA(3G). Sony support says the device does support VOLTE and I need to talk to carrier. Carrier says if the device supports VOLTE it should work. Nobody is giving good support. Does anyone know?

The build.prop of this device shows ims & volte disabled. This is not controlled by the carrier. This is controlled by Sony. I can enable volte via build.prop and I now see mobile networks settings. It is listed as "Enable VoLTE". VOLTE still does not work. When I enable ims in build.prop the device hangs on boot(Correction no boot hang). To me this seems as though the ROM has incomplete VOLTE & IMS support which a lot of VOLTE providers use. Is there a known instance where a F3113 ROM has working VOLTE on any network in the whole world?

Update: Just tried an AT&T sim in the device. Same issue. VOLTE does not work.

According to three UK's website/page volte only works when all other methods of making a call fail I.e. 3g+,3g,2g only then will it revert to volte calling, clearly states it supported but no VOLTE settings anywhere I'm running a unlocked xa with my carrier's stock out of the box firmware three UK. I've never had a compatible device before so no idea how it really works(must call in the store to find out more)

is xperia xa supports the VoLTE..??
i am using my Reliance jio 4G sim card.... but my phone doesnt show me the VoLTE icon on notication bar.... so what should i do to enable the VoLTE..!!!

have you tried to contact your network service provider if it is supported on their network? this is mostly a network service

Well according to my network(three UK) the xa will only revert to volte calling if all other ways to make a call fail due to no signal ect. My xa has my networks WiFi/volte calling app pre installed plus a app for account management and a splash screen but it runs the same firmware no as a network unlocked xa as that's what it is there is no option in the settings to enable volte calling by default.

That's not quite true volte.
That's the same kinda deal as O2's tuGo app.
In that it uses a data connection to manage the call,

I know that, they even call it 4g supervoice rather than volte for the less techie peeps its there reason, I personally think that the xa is NOT VOLTE enabled by default and someone screwed up the whitepaper as I know my network do it

[Gaurav31]

what is this VoLTE provisioned flag.....??
it is enabled but still not showing VoLTE in status bar😕

[1adrian1]

See according to my network three UK the xa is volte capable. My network call it 4g supervoice rather than volte calling. The link below is a screenshot of my xa being confirmed as volte/4g supervoice capable with the three in touch app on my network it'll only revert to volte/4g supervoice if there's no 3g signal or WiFi calling available it'll revert to a data connection.

Hi,
I recently purchased XA Ultra and I am using Reliance JIO sim and it is a complete 4G network. But XA Ultra has only LTE, enhanced LTE capabilities are not there and this is found in many low end phones. XA ultra uses Mediatek MT6755 Helio P10 processor which supports VOLTE. I am confused as why it is not available for my phone. A software update would fix this issue?
