Question Will CSC Change Effect VoLTE? - Samsung Galaxy S23 Ultra

If I change my CSC from TEL (Australia) to SEK (Ukraine) in order to enable native call recording, will VoLTE still work with my carrier (Telstra Australia)?

I answered my own question. I ended up changing to SEK and VoLTE works fine.

VoLTE is not CSC dependent. Never seen a line that says enable or disable VoLTE.

Volte option greyed out

Why is my Volte option greyed out and permanently set to ON?
Can this be changed...?
To use VoLTE your carrier have to support it

I believe my carrier supports volte, but it is like it's set to be always ON in my s9 plus??
So, is your question that VoLTE works but you can't disable it or VoLTE doesnt work at all and neither do you have an option to enable it ?

Can somebody test VoWifi working on Poco

I have added the following lines in my build.prop and was able to enable VoWifi on my phone. Unfortunately Indian carriers don't support VoWifi so don't know if it works. Can somebody who has a carrier supporting VoWifi pls test it for me.
Add the following lines to build.prop and then configure VoWifi in settings/sim cards and mobile network/ sim card setting/last menu item in the sim card menu.
persist.dbg.ims_volte_enable=1
persist.dbg.volte_avail_ovr=1

Anybody who has tested this with network support present in their country. India carriers don't yet support vowifi but shortly will start.

BSNL has VoWiFi for broadband connections but you need to pay Rs. 1000 as one time subscription charges.
I've installed this module on Magisk :
https://forum.xda-developers.com/apps/magisk/module-v4-volte-enabler-t3649613/page29
I can see VoWifi option, but i don't know how to test.
My carrier has VoWifi.
I already have VoLTE before install this module

What I did was put the phone on airplane mode and tried dialling, it asked me to use vowifi but as my carrier doesn't support it , I couldn't test it.

Tried that but doesnt work. It seems that VoWiFi doesnt work with the Poco
Doesn't work for me too.
Can't be in airplane and use vowifi. Must be connected to carrier network
btw IMS vowifi is registered

That's very strange, the whole purpose of Vowifi is when u have a very bad or zero network.
Doesnt work for me but shows me option in settings
Mh IMS VoWifi isn't registered.. so it can't work
if you know how to, then it will work

Working for me since I bought this device.
Ps : using Jio 4g
Must be a carrier problem. If the carrier doesn't have volte support in that area or for roaming, it will fallback like old days -_-

Why do you make such un informed replies?
As of now both Vodafone and Airtel support Volte in home network only. The required modifications to enable Volte while roaming are being done. This is according to Airtel customer service. So this has nothing to do with our handset or its software.

I am using vodafone, volte works for me while roaming also. Have tried it in Aurangabad while my sim is from Mumbai.
But today seems to be a problem with networks volte with Vodafone is not available in home network also.
PS customer service guys are pathetic and make up stories for getting out of queries.
Volte Restore
Run the below code in your dialer app manually. You should see a message stating "Volte Carrier check disable" else run the code again.
After 30 seconds your volte network should be retored. Pull down the notification bar to check for the volte symbol.

Can't get VoWifi to work

Hi, I am getting desperate now trying to get VoWifi/wifi calling to work on my mate 20 pro.
My wife has the same phone, and same Carrier (even same plan)
The carrier is called Talkmore which is an daughter company of Telenor. I'm living in Norway btw.
The thing is that on my wifes phone, the carrier says Telenor ViWifi in the top corner, but on mine it says Talkmore HD.
We did have different apn's also, but I changed it on mine to the same as my wifes phone, but still it's then same.
And yes, I have turned on Wifi calling in the settings
I have talked to Talkmore, and everything is okey on their part, and you know there is not much tech help to get from carrier employees.
Does anyone have any tips that I can try. It would be appreciated.
Thanks in advance!
Hi,
With this app https://play.google.com/store/apps/details?id=by4a.setedit22

There is a difference on mine and hers. The first photo is mine, the second one hers.
Some carrier are calling Volte and/or Vowifi HD. Maybe yours is one of them.
Disable Vowifi, Choose airplane mode, then enable wifi, then enable vowifi.
Does HD icon shows while still on airplane mode with wifi and vowifi on ? -If so, your carrier use the HD icon for vowifi.
Your carrier is actually using HD icon for Volte.

What happens if I remove the extra stting that I have on my phone? Maybe it's worth a try?
I would try to add on yours, the key:
wfc_ims_enabled
with value set to
1
wfc_ims_mode_X values are:
3 for Mobile prefered over Vowifi
2 for Vowifi prefered over Volte & Mobile
1 for Volte ptefered over vowifi
_X is :

Hi. Sorry for the late reply. Been busy the last days.
I tried your suggestion which did not work. I also messed around a bit, including deleting the string like I said, but no luck with that either

Lg phones g8x, g8, v60, velvet Volte enable for all carriers, unlisted countries also

I will try to keep this post as small as possible.
This will enable Volte for Phone ranging from Lg g8x, g8 and V60 without root or modifying the system files.
Many have posted ways to get it, Iam only trying to help out the small bits missing for enabling on carrier without MBN in the LG phones.
1)First remove the sim from phone and then head to the phone dialer .
2)open field test menu under *#546368#*'your model number'#
3)open IMS setting(If does not open or shows only LG IMS without carrier and country , then insert sim enable universal enabler under field test, create a new config and select the 4 last options and restart phone without sim )
4)back to Field Test, IMS setting enable the below options:
4.1) under subscriber enable for IMS,ISIM, USIM
4.2) Under Xcap\Ut. Under General= enable UT,USSD Over IMS
Under ETC enable 'Check IMS Registration', 'Use rule-ID from response', 'Query on bootup'
4.3) Under GPRI VoLTE/VoWIFi enable VoLTE, ViLTE,VoWIFI,VIWIFI
4.4) Under test : Preference Operator can be set as 'OPEN' or your carrier short name. Really does not make difference for some operator , some do require it to same name as theirs.
Preference Country this is important as this decides if VoLTE gets enabled, Find your country short code example USA is US , India is IN. Find and try different short codes.
Enable:- 'support Volte AT command', VoNR, 'UAC Enabled', 'VoLTE Setting Enabled'
5) Go to Phone settings, Under network , APN settings add APN :-
APN name = ims
APN = ims
APN TYPE = ims
6) Save APN and make sure it shows under the APN names, Head back to field test menu under *#546368#*'your model number'# , open test , IMS setting and the press 'restart IMS process' wait for 1 min or so , see if the VOLTE icon shows up in the top of phone.
Points to keep in mind:
*#4636#*#* wont show registered sometimes, that's ok as long as you can make a call with HD written on calls or , if during the call it is 4g or LTE. provided VOLTE icon shows always on top of phone.
If in case VoLTE disappears at any point, no need to go through all these steps , only need to go to field test, under IMS setting , do 'restart IMS process' .
Vowifi is not confirmed, IF someone does get it please share their Operator name and preference country short name.
Please who ever gets the Preference country code, please share here for others, mention the country name also.
Cosmote Greece - GR, it worked. The only method that my v60 got a volte. Thank you!
Initially i did colincsf and it worked, but after updating to Android 13 and installing a patched modem, IMS settings was empty and I couldn't change settings. Removing the SIM showed the IMS settings option and procceded with the steps above.

Your case you dont have the full service menu , either cross flash to another region prefer europe. Then try the service code and check. I haven't tried on lg v50s .

Anyone tried with lg v60 L-51A docomo varient ????
so the fieldtest/ims option only depends on device country variant and not available on all devices?
Good right up,but won't work with all carriers.Tried this with a unlocked T-Mobile V60 for AT&T and still no VoLTE.Doesn't hurt to give it a shot though!

true but that depends on the carrier also, the country i was in recently , they had 3 carriers tried volte for 2 carrier it worked but the 3rd didn't, tried it on another phone which had default MBN in the firmware, still no VOLTE, understood volte has to be enabled from carrier side and also if they block volte for device specific then , its upto them. Talk to AT&T, have a phone that has VOLTE in the mbn . see if then it works. Also make sure the country code is right, for example you used US for t-mobile, it wont be the same for AT&t, try USA, or something in that line.

in SVC menu, go to MID Info, see if you can modify NT Code. Once NT Code is not matched with stored one, field test menu will appear
in #5 the ims APN won't be saved in my case. But I got "ims" APN list under Field Test-Modem Settings-PDP Setting-APN setting. Still can't get "IMS setting" open, only says "Not supported". "Modem UUID" shows not supported as well. LAOT menu only shows “SIM INFO” option, missing "LAOT Setting" option.

You sir are a life saver, i have had LG velvet 5g phone since september 2022, but not able to get VOLTE working in india but following your guide i had it working today. I didnt have to do 5 and 6 number option, as soon as i inserted sim to modify network apn settings, volte option showed up on top and i made the first call. please update your title to include LG velvet 5g so it comes in google search as many are looking for a fix on this thread also. many thanks to you as I was not sure what to do with this phone any more. thank you
Thank you so much johndaniel!
As abeykp stated just above, it works on LG Velvet 5G, and in Europe also, finally!
It's maybe a mix of actions with the post below, as I tried it first (it did activate the VoLTE option in the network settings, but was still not working for me):
Guide:-How To Activate VoLTE,ViLTE,VoWIFI&ViWIFI LG Devices-LG Velvet 5G
Hi Guys Am Baljeet From India There Is A Path To Force Enable VoLTE On The"LG Velvet 5G LM-G900" Specifically Your Version Which Is The "LM-G900". By Default This Feature Is Disabled On This Model. Follow These Steps Given Below: A). Go To The...
forum.xda-developers.com
Now I can call & receive calls in 4G/5G without my network switching to 3G!
I also confirm that points 5 & 6 are not needed, at least on my network in europe. And I used OPEN and EU (it was actually already showing up in the line in IMS settings, but not under Test in point 4.4). I guess you can also use FR, IT, ES, CH, etc depending of the country you live in europe, it works for my country, but I kept EU as VoLTE might keep working when roaming or with another sim inserted.
You can add in your short (but so usefull!) tutorial that you have to insert the sim card before point 5, or you won't be able to get to the APN settings.
And for the LG Velvet 5G, Field Test menu is accessed with code #*462633*#900#
I will test it with my LG Wing 5G and will report if it also works.
Now I still have to get to the Field Test menu on my Korean V50S (sim unlocked STK model). Didn't manage yet to pass start the flashing process to cross flash with the Korean Open firmware, any help welcomed...
Hi, I alo have Korean V50s, does you mean we still don't have Field Test menu? so no way yt to activate VoLTE on our phone?

I don't have access to my V50S right now, but I think I couldn't get the Field Test, probably same model as yours.

Let us now if it worked for you.
The only problem I had with the V50S was that it kept going back to 3G when calling, and it didn't have one of the frequencies that is used in my country. So sometimes I was left without being able to take or make a call.
IF only LG would let us unlock all bootloaders freely, now that they left the mobile market...
