I have two used LG G8x - G850QM (unlocked) and G850UM (Sprint unlocked).
I am on T-Mobile for years.
The G850QM on T-Mobile shows wifi-calling on the menu and it works.
The G850UM has no wifi-calling switch on the menu, just not there.
I installed WiFi Calling app from Widget7 from Play Store. The app seemed to bring out a hidden WiFi calling menu. And the WiFi calling works. I confirmed the WiFi calls on my T-Mobile bill portal.
Hope this can help
Does it do anything for Volte?

I used two different VoLTE Check app. Both indicated VoLTE ACTIVE.
I dai!ed *#*#4636#*#* to go into Diag menu. "Phobe Info" indicated that
VoLTE provisioned
Video Calling Provisioned
WiFi Calling Provisioned
EAB/Presence Provisioned
But all the "switches" were grayed out.
This is in my daiily driver LG G8X g850UM on T-Mobile.
I assumed VoLTE is working automatically.
Most people with tmobile on this phone have found that for calls the phone goes from 4g to 3g when making a call. You will only see this transition if you are looking at the 4g indicator while on the call.
The concern is when T-Mobile discontinues 3g next month then you will not be able to make phone calls.
If you dont mind you might take a look as you make a call and see if it stays on 4g.
I understand. I, with 4 LG phones on Tmobile, am in the same boat with a lot of people. And I have purchased more LG phones- 3 V40 , 1 G7 and 3 Q7+ before I learned about the network transition.
Tmobile did a piss poor job in explaining the 3G shutdown.
Today is 4/1, with my Sprint-unlocked LG G8X, I can make a call and the LTE indicator stayed on.
This is what Tmobile has announced.
As of March 31, 2022, Sprint’s older 3G (CDMA) network will be retired
As of June 30, 2022, Sprint’s LTE network will be retired
As of July 1, 2022, T-Mobile’s older 3G UMTS network will be retired
Also Tmobile has delayed Sprint 3G shutdown until May 30.
Downloaded app and enabled, but all my buttons are still greyed out and it definitely still goes to 3g during a call? Not sure why it is not working on my phone?
It has something to do with the combination of native ROM, TMobile or Sprint SIM card in use, provisioning of VoLTE, and the (T-Mobile) LTE channels supported in your phone. I have not figured everything out yet.
It will be a rough ride for me until July 1 when the transition is over.
Forget what I've posted. I f'ked up. I mixed up 2 models.
I just received a T-Mobile email telling me my daily driver G850UM does not have the Volte turned on.
I looked up Phone Info and found Volte Provisioned switch is off and grayed out. When I wrote the post on March 31 the Volte Provisioned switch was on but grayed out.
I swap SIm card to the G850QM phone, and the Volte Provisioned switch is visible and in ON position. Look like I need to switch phone near term. And then find a way to cross flash QM firmware onto UM model. Need research. Fvk T-Mobile and the other two for doing their fake 5G rollout.
Thank you Buontinh. Got Volte, WiFi calling and video calling on my LG G7X G850UM on 20P software.
Uploaded the modded abl_a to both _a and _b. Insert an active T-Mobile SIM card, got new TMobile bootup logo. Got the wifi-calling switch. Got into Phone Info and saw votle Provisioned, WiFi calling provisioned, and video calling provisioned. Grayed out however. I made a call to my landline and the 4G LTE light stayed on. I guess it is working.
Still on Android 10 however.
The most difficult part was to get the phone on EDL mode. Must have tried 20 times before getting the "dark screen" EDL mode, only to learn that a Qualcomm hs-usb qdloader 9008 driver was needed too.
So I followed the below directions from reddit and it worked great on my velvet. I did the same thing on my LG g8x with *#546368#*850# code and I now have Volte, however phone still drops to 3g when it makes a call any thoughts on how to fix that?
There is a way to force enable VoLTE on the "LG Velvet 4G Dual Sim" specifically your version which is the "LM-G910EMW".
By default the feature is disabled on this model variant for who knows why.
Follow the steps below: 1. Click on the "Phone" app and dial "##4636##" -If done correctly it'll automatically bring you to the "testing" settings menu.
Click on "Phone Information" -you should see a list of VoLTE settings however by default they are disabled and greyed out but don't worry there's a way to reactivate VoLTE. (You Will Come Back to this Menu later)
Go to your file app and create a file named "enable_ue" -thats all you need to do just create the file, nothing more nothing less.
Go back to the "Phone" App and dial "#*462633*#910#" -This code is specific to the variant and will not work on other non LM-G910EMW Phones. Dialing this should bring up the "Hidden LG Menu"
Select Field Test>Universal Enabler>Create New Config -a menu with check boxes for VoLTE options appearing
Select the boxes as follows "VoLTE" "ViLTE" "VoWifi" "ViWifi" And finally hit "Confirm" -a prompt will appear stating "Vo Services Updated"
Immediately restart your phone to allow the settings to kick in
After your phone has restarted go into your Settings>Network & Internet>Mobile Networks -If done correctly the VoLTE option will now be unlocked and available.
Switch on the "VoLTE"
Now to double check that your phone now truly has VoLTE enabled, repeat steps 1-2. If done correctly the menu should now say "VoLTE Provisioned Video Calling Provisioned Wifi Calling Provisioned " -if these 3 are all switched on then you have successfully force enabled VoLTE on your LG Velvet 4G Dual Sim LM-G910EMW, congratulations!

Hello, I sintalled the app and it leads to a LG look menu I never encoutered with a WiFi calling switch !
However, when I go back to the app, then press again the button to open the menu, the switch is disabled.
Any idea how to keep it active ?
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 .

Yes , some of Korean model had there bootloader also locked. Since i haven't tested on v50s not sure , if i can help. Were u able to unlock bootloader?, If so have u tried to cross flash and check .
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.
Did you test this from darrelama:

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...
