F8332 India Customization Volte and WiFi Calling

I flashed my F8332 with India Customization rom and I have both VoLTE and WiFi Calling toggles on the menu. Does this mean I can use AT&T and t-mobile with thesd features. I am not in the USA but I am curious if with these options available now on the menu it might work? Let me know if any of you try to flash India firmware and can try to test these features. Thanks.
Anyone?
VoLTE and VoWiFi reg.
Could you please tell me from where you did that update?
Yourself or sony centre?
Need some more info...

Get Flashtool, and install whatever firmware you want.
Anyone knows if there is any Customized ROM for F8331 with volta enabled? Maybe India as in F8332?
My Xperia XZ does not support Volte as the button "Volte Provisioned" is seen deactivated. They say that it works on Jio. I am having Airtel SIM. Can I enable Volte on my Xperia XZ by flashing or any other way? Thanks

How to Enable VoLTE

Hi guys. Just now received the XZP and I'm very excited about it. I want to know whether this mobile support volte. If it supports, then how can I enable it? There is not any options to enable it. I brought this mobile in dubai and I am using it in india. Here a network named jio supports volte. So could you please help me guys? How to enable it?
Dual sim or single sim?
It supports VoLTE in various regions and providers.
With single sim version i do not see Indian providers in modem configuration list and no Indian region firmware.
If you have dual sim model, then maybe you have luck with flashing Indian firmware https://xpericheck.com/cda/1308-6241 (i hope my assumption is correct that Customised IN refers to India)
I have not digged into dual sim firmware yet, so cannot guarantee it for you.
Please use search in XZ and other sony forums to know how flashing sony firmwares works. Too long and complicated to write it out here.
Also, ask from JIO if they plan adding support for XZ Premium. This will indicate if you would get VoLTE with Indian region firmware.

Yes I am using the dual sim version. Is there no other way I can enable it without flashing the firmware? Or should I wait for the next OTA update?
Flashing the correct region firmware is the simplest solution.
Also currently there is no other known method.
If you have UAE region firmware then OTA update will not enable VoLTE for other regions.
I have now checked the firmware that i previously shared. There is special modem configurations in DS for Indian providers...
amss_fsg_maple_dsds_airtel_in_ims_tar.mbn
amss_fsg_maple_dsds_reliance_com_in_ims_tar.mbn
amss_fsg_maple_dsds_reliance_jio_in_ims_tar.mbn
Also the oem bit will tell phone which configuration to load.
So i think you would be good to get VoLTE if you flash https://xpericheck.com/cda/1308-6241

VOLTE patch

Could anyone of developers make a volte patch for xa as it is a core feature of nougat and Helio p10 also has it
But Sony doesn't want to give this feature in India Xperia xa f3116 deliberately
In nougat it's not working when I try *#*#4636#*#* setting
Volte provisioned switch could not be turned on and it were off by default
In UK it is on by default and it is supporting volte
So can anyone build a volte patch for xa???
Or
Could anyone have a solution to turn on the volte provisioned flag on in India xa
Thanks for every one who guiding me

Your right about the UK and volte if your network supports it which mine does had a text message from them the other week to say that 4g super voice(what my network call volte) is now available for the xa F3111
Sent from my Xperia XA using XDA Labs

Did you update the "New update of 9.8mb"
don't know what changed they have made in this patch, may be this patch include VoLte features.
i'm unable to update, since i have unlocked the bootloader.

sure thing!!:fingers-crossed:
Noppe that 9.8mb update had nothing to do with Volte. I checked everything can't seem to figure out what it was about maybe just some fix or something but no Volte yet ?

Yes it is not volte patch
But I think you should update to it
May be it has some fixes that are really necessary to our xa
Cause Sony is not so generous that it will give an update with extra feature in very short time from its latest update
I have listened about call log is lagging after nougat update
Not sure every one has this problem or not
But may be that 9.8 MB update relates to that problem or any other else
I suggest you to update when you have a free useless boring time to time pass with that update
I have a XA1 Dual Sim, but the situation may be same.
if you go to *#*#7378423#*#* > Service info > Software info under Current Modem Config if you have Vodafone LTE On, it has the default config, but if you have Jio LTE On, then the config changes to a Jio Specific Config, one of the reasons why my phone restarts when i change the settings between Vodafone and Jio, it needs to reload the Modem config file.
Now I believe Sony has VoLTE specific config for each of the Operator and the software is looking for some settings in the SIM to enable VoLTE Provisioning.
If anyone has root and can browse the content for the system folders /system/etc/customisations/modem/ , and could check if there are different config files for each of the Operator, take a screen shot, or may be one common config for VoLTE if all SIM support VoLTE.

How can I activate VoLTE?

I can't any ideas?
I have Xq-as72
Settings \ Network and Internet \ Internet settings \ 4G calling
VoLTE is 4G Calling on this device.

4G Calling is going to be in the Mobile Network menu, Internet settings just asks to download MMS/APN settings

Looking at your model number, you have HK varient which won't support VOLTE if you are trying to use in EU.

Why on earth would VOLTE be locked out of a region? I also have the international model XQ-AS72 and am in Australia so is this why I can't seem to see VOLTE setting as well?
Edit: also how do you view the information you've posted?
Bump
Also this code gets into the screen I was after.
*#*#4636#*#*
I have the exact issue with the model. Not able to turn on Volte. Bought it from Hong Kong and using it on indian bands. Why is this happening? Is there a fix?
It's pretty **** we have this issue. Thanks Sony....nice job.
In US version XQ-AS62 there is an option to enable VoLTE from Mobile network.
As far as I know sometimes SIM companies block VoLTE as on my Xperia X Dual, I was able to use VoLTE in India on Jio but here in US T Mobile blocked it so no option of VoLTE even though phone had support. However on Xperia 5 II it's available and works.
Did you get Volte on Xperia 5 ii in India?
Did you try it on Airtel and jio?
Can you please provide the firmware version of your xperia 5 ii.
I have xperia 1 ii model XQAT52 and I don't get Volte in India on this device.

I am currently in US so can't check it and firmware version is 58.1.A.3.87 but VoLTE is supported out of box.
VOLTE requires the cell provider to provision for it in the firmware of your device. VOLTE will not work for a USA provider if you use a phone made for a different market like hongkong because the firmware doesnt expect it. You can blame the cell providers for this.
Different versions of Xperia 5ii
I found there are 3 different versions of Xperia 5ii. XQ-AS52, XQ-AS62, XQ-AS72 Anyone know the differences on these three models?

Can you explain? Volte working fine on India on Xperia 5ii?
why would you need volte? You don't have 3G network?

Is it possible to enable volte in xperia 5 in india?

Is it possible to enable volte in xperia 5 in india? I bought xperia 5 j9210 from online. Unfortunately volte not working in india. is there any workaround? My wife is also using xperia 1 it also bought from online since sony stopped sales in india, volte is not working for that device aswell. Thanks in advance.
You may have to verify with your carrier if they support volte on the Xperia 1 & 5 at all?
if so, then then it may be a question of getting the firmware for your country/region flashed to the phone(s).

I am asking for your Xperia 5 only. Probably that same region's firmware (if it exists) on my 5 III might enable VoLTE. So far I have tried Global (Vodafone LC not Net Locked) and SEA but both haven't worked in enabling VoLTE.

@yogeshpatel7 If it's not a lot to ask from you, could you PLEASE spare 5-7mins to go through my request here (https://forum.xda-developers.com/t/enable-jio-volte-and-vowifi-on-xperia-5-iii.4467977/) and see if you could help enable this for 5 III? I hope I am not asking a lot from you and it would SUPER APPRECIATED if you could help make this work. Right now my phone is practically a paperweight as I can't make any calls as Jio is a 4G ONLY sim and doesn't work without VoLTE.
