The volte is enabled based on what network you are using. Tmobile has shunned our phone and its impossible to have VOLTE. The only network giving us an official blessing is VERIZON the volte works so good. Forget about sprint and ATT is not consistent with it's game right now either.

VoLTE activation

Hi,
I have XZ2 Compact (Locked Bootloader) and after few tries, I think I managed to get VoLTE working with my carrier 2 days ago on Oreo ROM.
Maybe this will help others

I bought H8324 (DualSIM) with Central Europe 1 (CE1, CDA 1313-3194) firmware in local store, my carrier is Vodafone Czech Republic and VoLTE did not work out of the box after VoLTE and VoWifi activation in My Vodafone.
There is no option to activate VoLTE switch, it is grayed out. (Hidden Settings -> RadioInfo -> VoLTE Provisioned).
My carrier sells just XZ2 single SIM phone.

After some attempts 2 months ago with different region firmwares, that offered VoLTE Provisioned switch to be enabled (e.g. DE, CDA 1313-6204) and did not work (when call started, it immediately dropped from LTE to 2G/3G ), I tried it again 2 days ago.

On XperiFirm I found Global Vodafone Oreo firmware for XZ2 (H8216) and after UNSIN of oem_X-*.sin and system_X-*.sin files and exploring these files, I found that CDA 1313-8220 is the right firmware for Vodafone Czech.

So after that I used Newflasher to flash "hybrid" ROM.
I used XZ2C German fw (DE, CDA 1313-6204, VoLTE Provisioned can be enabled) and OEM file from XZ2 Vodafone fw (CDA 1313-8220).

To the Newflasher folder:

• I copied all (*.sin) files and two folders (boot and partition) from XZ2 Compact DE firmware (CDA 1313-6204),
• deleted userdata_X-*.sin file (I did not want to wipe my data),
• deleted original (XZ2C) oem_X-*.sin and replaced it for the oem_X-*.sin from XZ2 Vodafone,
• entered fastboot mode on phone (Power on + hold Volume down)
• and flashed "hybrid" ROM with Newflasher

After reboot and enabling VoLTE Provisioned, VoLTE (probably) started working as there is no 2G/3G on call but 4G+ (screenshots attached).

So far I did not noticed any real cons.
I found ONE BIG disadvantage, at least for me. The device has lost Play Protect certification, so I can not use Google Pay for paying in stores any more.
I just noticed changes in Service menu (*#*#7378423#*#*) :
Service Info -> Software Info
Customization Version -> 1313-8220_R14A
Current Modem Config -> euro/vodafone/vlvw/cz (used to be something like *general*)

Sidenote: German (DE) Oreo firmware was the only OREO firmware I still had on my computer beside CE1. Now there are almost just PIE on XperiFirm.

Can anyone try to apply the above solution to try to get volte on more carriers with our phone in USA? Thanks.

Hi,
To you and anyone reading this, I desperately followed exactly what rSG1t did after Verizon support failed to help me getting my xz2c working. I've got an unlocked H8314 (I'm in the US) that got data fine, but call and text were not functioning.

I did everything the same for except I just flashed the US firmware from XperiFirm. No replacing of any files or that stuff.

So to OP, yes I have an XZ2C with working VoLTE. My firmware is CDA 1313-0031 USA from XperiFirm. Also if it helps you, I have radio set to LTE only, and after flashing this particular firmware the VoLTE toggle in testing menu is enabled and not grayed out. After doing all of this, it finally works on Verizon with calling, data, and text all working beautifully.

So your XZ2C initially had a US firmware, an you flashed the US firmware from XperiFirm to it, and then everything works?

I am asking so, because I am in a pretty similar situation, except that my carrier is AT&T

only possible on verz

I'm in Canada using Videotron on the H8324. I can confirm that VoLTE is working using the most recent unbranded customized DE Firmware 1313-6204 52.0.A.8.14 but with both oem_*.sin files from the branded Videotron H8314 firmware. You can simply flash only the OEM files using newflasher if you already have a VoLTE-provisioned (like the DE) firmware installed.

VoLTE

Everyone who is using the XZ2 Compact on USA Verizon is using VoLTE. This phone does not support CDMA, so the only way it can make/receive phone calls is with LTE. (I am on Verizon.) My build number is 52.0.A.71. You may get more suitable responses if you specify which Country/Carrier and model of XZ2 you have. (8134 vs. 8234).

Glad it isn't just me. I have xz2 factory unlocked and am unable to call whilst using data due to my being unable to use volte

Wifi Calling on unbranded H8324 with Orange France

@rSG1t just wanted to say thank you ! I had a slightly different problem :
In France Orange doesn't support Wifi Calling on unbranded (non Orange) XZ2 Compact. I do have the option activated on my plan, but don't have the option showing in the menu.
Another problem is that Xperifirm doesn't propose any Orange Rom for France for the H8324.
So I followed your procedure with DE stock + Orange MCV FR/ES/PL/SK/RO for H8216, and it worked !

I also have the VoLTE enabled in the hidden menu, but I don't think I have this option in my plan (and I don't see the option in the settings menu), so I assume it's not working (which is not a big deal as my main goal was to be able to place and receive calls in my countryside house where I have no cellular coverage).

Hi Vinc1,

Can you Share both oem_*.sin(from the branded Videotron H8314 firmware), because I tried a number of times to download firmware from Xperifirm but it got stuck, and I required only two files, please share it will help to me

Not working, Only Indian Firmware XZ2 OEM have capability to provide Volte & Wifi Calling both, whatever Firmware you have in Xz2 Compact, just Flash OEM
