Hi there,
Is there anyone on this forum that has an Xz2 COMPACT with the VoLTE enabled? If yes, can you please let us know which firmware are you using? Many Thanks

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.

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).

Vowifi and volte on orange FR network

Hi and happy new year,
I manage to get volte and vowifi working on orange FR on my XZ1 compact by flashing oem.sin from XZ1 orange firmware. But the support had to manually activate it for my line.
The problem is that after few days my phone refuse to use volte or vowifi. I contacted the support again, they reactivated manually the service and it has been working for some days and stopped again...
I think they are restricting the service per device so that it's working for the XZ1 and not for the XZ1 compact. I don't know how my phone is identifying itself on the network but would it be possible to pass as an XZ1 instead of an XZ1 compact ? And if possible how ?
Thanks...

I had play about yesterday trying to get volte working. I'm on O2 and still on Oreo and my Current Modem Config in service menu/software info up until yesterday was using amss_fsg_lilac_tar.mbn. I tried the method of flashing an oem.sin as suggested from another region but still couldn't get it work.
I couldn't find an O2 branded Oreo fw so I download an O2 Pie rom from Xperifirm and tried the oem.sin from that, which worked for all of 5 mins before I had to start over because of "phone not responding" message popping up as soon as I'd dismissed it.
Long story short after some testing, I replaced the config.prop as is and modified the cust.prop in oem/system-properties and and replaced the modem.conf in oem/modem-config now volte works, and shows it is now using amss_fsg_lilac_telefonica_uk_ims_tar.mbn in Current Modem Config. My Customization Version and Active Customization has also changed from 1311-0104_R22B to 1310-7514_R2C.
EDIT:
Not sure about vowifi as there is no indication if it's being used when wifi is active.

Q: How to know if VoWiFi is working ?
A: Put phone in airplane mode and reactivate WiFi only. If you are able to make a call then VoWiFi is working.

I tried this and it worked. In normal mode the icon to indicate vowifi comes up after 30 seconds or so.
I've also added the following to my build.prop.
Code:
#voLTE_Options
persist.dbg.ims_volte_enable=1
persist.dbg.volte_avail_ovr=1
persist.dbg.vt_avail_ovr=1
persist.data.iwlan.enable=true
persist.dbg.wfc_avail_ovr=1
persist.radio.rat_on=combine
persist.radio.data_ltd_sys_ind=1
persist.radio.data_con_rprt=1
persist.radio.calls.on.ims=1

After flashing oem.sin from orange XZ1 firmware my modem config is
amss_fsg_lilac_france_volte_vowifi_tar.mbn
And my customization version went from 1310-8853_47.2.A.11.228_R4C to 1310-4288_47.2.A.11.228_R11C.
I also have the system menu to turn on vowifi ...
All of this looks OK and was perfectly working after they manually activate the service.
The problem is that only the XZ1 is supported by Orange and not the XZ1 compact...
So the service stopped working after a few days... And I'm stuck there...

Try using the amss_fsg_lilac_ee_ims_tar.mbn config file instead. Isn't that who Orange operates on?

I misspelled the modem config I curently use, it's amss_fsg_lilac_orange_france_volte_vowifi_tar.mbn so I think I'm good with that...
They probably activate/deactivate automatically the service by looking at IMEI/ESN number and extracting the phone model...

I'd try an oem.sin from the same device and change the modem.config to either orange_spain_ims or orange_romania_ims to see if that helps. Google "ims volte" to see why.
Failing that, not sure what else to suggest. If they are actively blocking based on imei, I'd look to change carrier.

Question OOS 11.2.5.5BA/NA 5G/Dual Sim?

Hi all, I think I already know the answer to my question.... I just want to be 100% sure as my searches are not quite revealing my answer.
Like many...when I received my NA OP9Pro I was disappointed to notice it wasn't dual SIM. Sent it back and still waiting for a refund for almost 2 months now. (That's a frustration with OP in itself...makes me want to go back to Samsung....UGH!) Anyways, I currently have an LE2120 (Chinese Model) running OOS 1.2.5.5BA (European version) and I am well aware that out of the box the NA version does not come with Dual SIM hardware.
The question that I am not 100% sure of is would the software build still allow dual SIM? My gut strongly tells me no..
The reason why I ask is that currently I don't have access to 5G. I thought it was because my work SIM didn't have 5G enabled on the carrier, I was incorrect. I still don't have access to a 5G, just shows 2G/3G/4G. I thought maybe it is because I am using a EU build here in Canada where maybe the bands don't line up...I have done searches on why 5G isn't available but nothing seems to fix it.
Just a shot in the dark...for people much smarter than I am!

No, simply running EU rom on NA hardware does not enable dsds. You can setprop for dsds but it doesn't work properly, seems to wire the first sim card into both slots and cause a conflict

Maybe I didn't word my question in the correct fashion.
I have dual SIM hardware, in my case it is the Chinese Version but I'm told the hardware doesn't differ as it still a Global Version.
The question is NA ROM, on Dual SIM hardware. If the rom itself supports it. I would just try it, but then I have to wait for the next update.

If you have LE2120, then the EU build should get you dual sim

I have LE2120 and I'm switch to Oxygen OS and trying build AA/BA/DA all working with sim dual
About 5g .. i have same your problem no option 5g only 2g/3g/4g
First check your country bands support
First try:
*#*#4636#*#* and choose NR/LTE/CDMA/EvDo/GSM/WCDMA if not fix 5g
Another way to fix:
I'm fixed 5g same steps its was on op8p
Sorry about english

So you have tried your LE2120 on AA? Dual SIM is all working ok?
I feel like switching to AA would get me unto the proper bands here in my country, but leary to do it because then I have to wait to the next build. Unless I decide to go root/magisk.
I did try the *#*# method, but that doesn't do anything. I have tried several different dialers and it never brings up this menu everyone talks about.

Any status on AA working with dual sim? I see that you never responded. I have the new .7 OTA update, but still hesitant to put it on if I loose dual sim

Question in xperia 10 mark III,which rom has working volte?

in xperia 10 mark III,which rom has working volte?

XQ-BT52_Customized HK_62.0.A.3.56
XQ-BT52_Customized SEA_62.0.A.3.56
XQ-BT52_Vodafone LC Not Net Locked_62.0.A.3.70
These rom above, I don't find volte option. My phone is development board
So my sim card can't be used in China.
Hope for help.
Thanks!

With XQ-BT52_Customized EEA_62.0.A.3.70 both VoLTE and VoWIFI are working with my provider here in Germany.
If you should want to use a ROM from another region, you will probably need to modify some config files to enable VoLTE for your own provider. There are some instructions out here...

Hi
Have you updated to 62.0.A.3.131? I have tried HK, SEA and EEA of 62.0.A.3.131 and I don't get the VoLTE toggle switch on any of them.
Thanks

I have now tried firmware version 62.0.A.3.131 of the following variants on my Sony Xperia 10 III XQ-BT52 and not got IMS to register or the VoLTE option to show on 2 different operators. Makes me think Sony must have locked it out somewhere else, especially seeing as Vodafone UK sell the 10 III, offer VoLTE and provide instructions showing how to turn it on.

Question Poco F3 MIUI global 13.0.7 : VoLTE and VoWIFI activation

Hi,
I don't have the Volte and vowifi options in the settings menu. So i tried the *#*#.... and nothing happen.
Otherwise i fond this phone to have a bad reception and difficult to phone with, so vowifi is a solution for me
when i'm at home.
Thanks in advance.

VoLTE *#*#86583#*#*
VoWIFI *#*#869434#*#*
use miui dialer or google phone

Thanks,
Already tried codes but i don't have the Miui dialer ont the global version and don't find a way to install it.

Does this solution require root? For me it says "Please apply to modem staff to get control rights." I am also facing constant disconnects, poor mobile reception etc. since the latest updates. It is really driving me crazy and I already tried resetting APN, mobile connections, full download of update etc. The only thing I have not tried yet is a full wipe as this will take a lot of time to reconfigure all the apps. But might be a further solution...

like for me "Please apply to modem staff to get control rights."

Sorry i don't understant what you mean, it's the default dialer for miui global. So it's already installed.

go to settings -> sim cards and mobile networks -> (click on sim card 1)
VoLTE and VoWIFI should be there

nope, this is the problem. When i dial the codes nothing happen and no vo*** options in settings.

I think those settings have been removed from MIUI, but phone codes still works if you enable them.
Try this: go to settings / system info / all specifications / click 5 times on internal memory
This will open a services option for sim 1 and sim 2
Check if volte and/or wowifi are enabled.
Then use the codes provide few messages above via phone app and go back to this service screen and re-check if volte and/or wowifi status are changed.
It worked for me.

Thanks for the tips, but not working for me

Hi there. Same problems here. The manual activation with *#*#VOLTE#*#*, which overrides the network settings, worked with MIUI 12.5, but since MIUI 13 the command does not work anymore.
So now you only get VoLTE if your network provider gives it to you.
I see you have a french language selected, so you might be using Orange or Sosh network. They don't support VoLTE on the F3... I contacted support, and they activated a switch on my phone line. And I had VoLTE on the F3 with MIUI 13 with Sosh for a few days, before it went away again...

I'm using Bouygues network and volte is activated on the network. My problem is VoWIFI, since i have a very bas reception at home. Otherwise the network connection is very bad and i always have blanks in phone calls.

Anyway, if you enable Volte or vowifi but your carrier doesn't support it or didn't enable it for Poco F3 the services, them simply couldn't work

It's true but they're activated by the carrier. VoLTE works sometimes and VoWIFI doesn't work.
I think i have to change this phone cause i can't use it. Too many network lost ...

Sad but true.. Poco is simply a mess..
My carrier said that Poco F3 is not supported by it's network (that needs a specific firmware update to support any single device), but it came out my F3 can connect to volte and vowifi

Just want to share my experiences before I am using poco x3 and I enable vowifi in the setting, when making call via wifi I can hear the other person but they cannot hear me, it turns out that poco x3 is not officially supported by my network provider... Months later I changed phone to poco f3 as it's supported by network provider and the vowifi work flawlessly since then..
