I am looking for the same solution. You have achieved it?
I have the same model and I can't get the code to work in the stock dialer. How are you guys getting to open up?
Thanks

Same here. If you just want to access the network settings you can download an app like "ForceLTE" or similar.
I'm facing the same problem, I am appreciated if anyone have the solution?
Check your carrier and location
Whether you can use VoLTE or not depends on a few things:
* Your location, your account with your carrier, and the model of your phone.
* The carrier, carrier account, location, and phone model of the person you're calling.
* Some carriers support VoLTE only in certain cities or area codes. Contact your carrier to ask about your area and account.

Thanks for your reply, the problem is I have no problem to have VOLTE by using Galaxy S10 with same sim card and I couldn't find the volte "switch" in the oppo UI and couldn't turn on/off. As a result couldn't use the VOLTE function. Therefore I do think it is the firmware problem from Oppo.
I just thinking about if I could flash the official Taiwan rom of same global phone model to my current one for solving the problem. But I'm not sure if it is workable or not.

Ah. I have CPH1919 (UK) and only option is call over Wi-fi. There is also no way to get to the hidden service menu either like in every other phone I've had.
If you know for sure that Taiwan firmware has it, then I suppose, in theory, it would work providing that it is also definitely CPH1919 - any other variant has different partition structure. Be careful. Read around and let us know. Good luck
I have a CPH1919TW, it's using the same global firmware as CPH1919EX (even Oppo TW provides CPH1919EX ROM for download), the phone will ID itself as CPH1919TW.

May I know if your phone have the VOLTE enable switch in the network manual?
Hey guys,
neither my Wifi Calling, nor 5G doesnt work on my Redmi K30 Ultra. Not sure whats the deal behind it, maybe its the Mediatek chip or that it doesn't pass Safety Net or that its not made for Europe.
Anyway: Can we hack this somewhere? Maybe modify some props or something and magically make it work?
Thanks so much! <3
More info: I've done the usual stuff like activating Wifi calling, VoLTE and 5G in settings and also disabled carrier check via number code. I also tried all 3 big carriers in germany
Telefonica/O2: Nothing works
Vodafone: LTE "works", it shows an HD icon at the top but Wifi Calling doesnt work and 5G doesnt either. Shows both VoLTE and Wifi Calling as enabled in Phone Info.
Telecom: Nothing works, but it shows in Phone Info that VoLTE and Wifi Calling is enabled.
@Mirardt
Per description the phone supports Wi-Fi calling, VoLTE and LTE, so I think it's not a chipset problem. Carriers will typically sell these data services with smartphones as part of a bundle.
I guess it is a problem with carrier ( data plan chosen ). You can try to contact your carrier and check if everything is correct from there end.
In no case your issue has something to do with SafetyNet API what is an anti-abuse API application developers can implement.

Hey there, yes everything is activated from the side of my carrier and also i spoke with vodafone technical support and they activated everything they could, reset the network etc.
Also both VoLTE and Wifi Calling work on the iPhone with all of the cards. So it has to be something on the phone.

Thank you for helping! @jwoegerbauer
Update: I have confirmation from german review website that both VoLTE and Wifi Calling worked for them on the K30 Ultra. Maybe that helps in identifying the problem?

Sometimes they just block per device model (supporting only phones that were certified for their network) and you need to convince them to let you in
Or, you could (again) play with props like ro.product.manufacturer and ro.product.model to pretend you have some fancy Samsung - bcs if it shows enabled in the settings, it's likely blocked at the time of handshaking and negotiating to use the service
It's also possible to capture the UE Capabilites offer (see attachement for my LTE part) and response - I will try to find where was the URL with know-how and instructions

I talked to a vodafone technical support guy and he said that everything is fine and open from their side. Also my phone runs with your fingerprints (Mi9T) for a week or so and it didnt change anything.
Do I understand it correctly, that all the methods you linked there only work with Qualcomm chips? Cause the K30 Ultra does have a Mediatek chip. :cyclops:

If the doc is only about Qualcomm, you will need to Google for e.g. MTK bands UE Capabilities
But MTK was usually more open, people were even able to easily change IMEIs.
There used to be a code for MTK Engineering mode, with options to enable bands and so

Ok do I understand correctly that UE Capabilities are parameters that my devices has that sends information if it can do 5G or VoWifi and so on?
After a bunch of Apps that refused to work with my phone (unknown device not supported) I did found one that looks promising. The problem is that I have only littly orientation and understanding. Can you see what setting might be relevent and maybe if we can get those UE Capabilities changed inside the app?
What I tried is switching the "Entitlement Status" of Wifi Calling on "Enable" (It was disabled as I opened the app), but nothing changed. The Entitlement server is left blank, maybe that could help?
Also I just swapped every possible thing from "false" to "true" inside ePDG Config, but it didnt help so I reseted it.
If you (or anybody else) could have a look and give me some direction I would grind it out myself!
edit: Upload doesn't work on this forum somehow, strange. Here is the Gdrive link.
Ok I just looked through every single option their is, screenshoting everything that seemed relevent.
There is band information that seems like it is what you mentioned and it is editable! @zgfg
Also a couple of other direct mentions of VoLTE, like props in IMS settings.

Very interesting, (as expected) you can control many things on MTK ( too many)
For LTE bands, I think you need bands 1,3,7,20 and you don't need TDD bands.
For 5G, googling tells me that for Germany you need: n1,n3,n28,n78,n258.
Suggesting you to double-check for your operator and enable what's missing and reboot.
B20 might be available in a shopping center, or dense busy district
In the Call* and IMS-Registration* screensots, are all those params enabled or you need to open another screen for each (modes)?
On the IMS, I would put VoLTE to Default, not to CMW500 - seems to be a mode for testing equipment.
Also, you could try SMS over 3GPP or 3GPP2 (that means SMS over IMS but when you register to IMS), but check does it still work over cellular
Last screenshot says that it's not registered to IMS, but seems there are additional settings for IMS authentication (that's about registering to IMS - VoLTE is an IMS service)
I pretty much tried everything out you suggested and it didnt work. Thats why I waited to work on that until I freshly reset my phone with GApps Pico and I did that yesterday. During the Installation process there are 2 question came up:
1. There are Google Carrier Services I can install through play store. No clue what it is, does it matter?
2. I have found multiple interesting sounding apps in system/priv-apps like "engineermode", MtkCapCtrl", "MtkTelecom", "MtkTelephony Assist" and "MtkTeleService", the only one I can find in Apps is "engineermode" and i didn't manage to open it. I tried to install the other apks but it didnt allow it. Anything that might help us?

Unfortuantely I was wrong about being to change them, but i do have most bands enabled. Im in Hamburg City so I should have very good access here.

Tried everything but it made no difference. Also tried IMS test mode on with and without SMS.
Also it keeps saying its not registered in PhoneInformation1.
Should we try to change those numbers in the VOLTE settings to something like this?
Edit: I activated logs telephony logs and somehow got a bug report without even calling somebody. Uploaded it.

wifi calling hardly ever works on foreign phones but my k30 ultra gets 5g on tmobile in my state.
Wifi calling hardly ever works on foreign phones but i get 5g on tmobile in my state , the k30 gets 3 bands that havent been listed , just get a mtk engineering mode app to see what bands you can work with.
The phone is relatively new and since it's not mainstream most carriers don't support it yet. Some people say they have VoLTE enabled and it works but I personally switched to Singapore EX and it seems VoLTE isn't detected at all so I started digging and it seems this issue is present in most Chinese phones. (https://forum.xda-developers.com/t/guide-activate-volte-and-vowifi-simple-and-clear.4116051/) In this thread they used the Qualcomm tool and exploit the bug in EngineerMode on OnePlus phones which we don't have an access to and since we can't root or unlock the bootloader we can't modify build.prop or change any system files.
-----Maybe it's my carrier, maybe it's the Singapore ROM so please if VoLTE and VoWifi works for you could you post here which country you're on, which ROM version and if you changed region before or not.------
First a warning: If you aren't tech-savvy, experiencing issues or want to potentially turn your phone in a paper weight do NOT try this at the moment. We do not have the tool to restore your phone back (wiping data might work but idk). You can send your phone to Oppo for repair but you might have to wait for a month or two.
I don't know if you need to unlock your phone from the other thread to have access to this mode(I did have it all decrypted during this test) but in addition to the *#808# engineer mode and *#*#4636#*#*(Where you can check if you have VoLTE enabled) I found we have access to *#36446337#.
In *#36446337# I managed to enter "Protocol test switch" -> "MBN TEST" and switch my profile from Common-Commercial(I think it was this one) to Commercial-DT-VOLTE. The phone rebooted and everything is fine but "MBN Validate" is giving me an error when I run it and I can't test if it works because I'm currently out of the country and my temporary SIM provider doesn't support VoLTE.
It's probably nothing and the error is because of the lack of developer files on the ROM but I need people who can test if these profiles act like the flashing from the Qualcomm tool in the thread mentioned above.
So once again if you don't have VoLTE enabled and are feeling a bit courageous - give it a try.
I think the problem maybe for those that changed to Pakistan build on Android 10 and then switched to Singapore ex to get ColorOS 11 and dual SIM meant that things like VoLTE do not work on those builds.
I did it a different way as wasn't bothered about dual SIM. I was on A.46 UK , waited for EU to get ColorOS11 , then switched to EUEX on sec5 and downloaded ColorOS11 c.57 through Belgium VPN.
VoLTE is working for me. it's not present in SIM settings( WiFi calling is) however when I look at my call log there is a VoLTE HD icon next to all my calls, so is working.
Since being on ColorOS11, I have tried several different regions on SEC tool, EUEX dual SIM, Singapore EX, back to GB CPW to check still works and now back to EUEX. Build number always changes to different region in about phone when I have made any changes and check however VoLTE has always remained working for me and is showing as provisioned in engineer mode.
I am from Germany and have a phone with Vodafone FW originally. I switched region to Singapore EX, than installed the Pakistan FW and got C.5 and C.6 via OTA. I switched the region to EUEX (DUAL SIM) and didn't receive the update to C.57, so I switched back to Singapore EX and got the update to C.57 when using VPN Hongkong, which was quite funny.
VoLTE and Wi-Fi calling is working fine with Vodafone, but you can't toggle it in the hidden service menu, it's just active! You can activate or deactivate Wi-Fi calling in the regular settings, but VoLTE is just there, you can't deactivate it.
Both Wi-Fi calling and VoLTE are shown in the bar on the top. With the former Vodafone FW, VoLTE was not shown with an icon, but it was nevertheless working.
Hy here T-Mobile shown volte and Vodafone don't shows but on the status bar there is the volte symbol

I am in the same boat as you. I rebranded to Singapore to get ColorOS 11 update, to use 2 SIM and Call Recording, along with Theme Store, etc.
While on my previous phone (Xiaomi Mi9) I had VoLTE and VoWiFi and my carrier supports them and my SIM has that activated by my carrier, on Oppo Find X2 Pro it seems for them to work is needed special Modem Profile for the concrete carrier you use.
My Carrier is not listed at MBN Test Menu, I tried all the profiles available there, all Commercial ones and all Volte Branded ones and they are not giving me VoLTE and VoWiFi options available in Menu or VoLTE or VoWiFi functionality.
This method used to work on Xioami and Commercial EU Carriers profiles gave me the VoLTE and VoWiFi functionality with just Activity Shortcut access to this menu on Mi9 and simple dialer code to activate VoLTE and VoWiFi switch in Settings.
Oppo Find X2 Pro is not sold officially in my country and by all carriers here and that is why there is no Carrier Volte Profile for carriers from my country and thus it is not possible to activate VoLTE and VoWiFi with other Carrier Profile from MBN Test Menu.
Maybe if we find a way with a Dialer Code or some menu to activate the VoLTE and VoWiFi switch in Settings first this profiles from MBN Test menu will work...
I am out of ideas for now.

I'm pretty sure they force disable most of this stuff with region profiles (/etc/oppoRegion* folders)
At this point I honestly care more about GDPR protection,VoLTE and removing tencent/heytap crap than call recording and theme store which I don't use anyway.
So my plan atm is to wait for Oppo to release android 11 .57 .ozips so that I can flash back to european firmware then I'll see if changing region to EUEX Dual-SIM works and it's limitations.
This method might help people on EU roms with VoLTE, and I'll test it myself in the future, but at least for now *#36446337# lets us adjust MTU, 4G bands and some other smaller network optimizations.
Okay I don't know where to post this but I found *#649010# and this is where it gets into the spooky territory. I never tried toggling any of the options but I think "Full-port switch" option lets us connect our phone to the qualcomm diagnose tool just like the OnePlus phones from the Carrier profiles thread. I'm just documenting this code here so we know we have an alternative to the OnePlus LogKit.apk option in our Oppo phones.

Works for me no issue. Try adding cloudflare dns to your setup, tether your phones connection to your pc while disabling your main connection and adding the number values from the original thread, fiddle with the loopback driver, disable firewall in windows or your router. Everyones connection and setup is different you just gotta find a way to make it work on yours.
Tl;dr it works you just got to tinker with it

I use the realme 7 pro on realme UI V1.0 and android 10, Build number RMX2170_11_A.34, Baseband version Q_V1_p14, kernel version 4.14.117, ColorOS V7. Using in Austria/Europe. Although both carriers (I use different ones with my two sim cards) support VoLTE and VoWIFI (it works well with Samsung S9+) I can't activate it on the realme because it is not even shown in the network settings. Is there anything I can do to make it work? I also tried changing the region of the device, but I always get invalid mmi code when entering *#3954391#. Also *#9434# does not work. I'm happy for any ideas, thank you!
U need to call your provider and tell them to do it, thats what i did and worked instantly
I'm on version RMX2170_11_A.36. Using in Germany/Europe. My carrier is Drillisch (o2 network). Both buttons are availble in settings. Only thing I'm missing is the VoLTE symbol in statusbar. VoWiFi symbol is present in the specific situation.

I also have no VoLTE option available. I am on Realme UI 2.0, build RMX2170_11_C.26. Before Realme7Pro I had Xiaomi phone and VoLTE was working there fine without any issues, so it is definitely activated on the operator side. Just Realme phone doesn't give me any option to turn it on...Any ideas how to enable VoLTE here?

No, it seems that it would require the operator to activate VoLTE for our phone model and I didn't find any hidden menu where I could force enabling VoLTE.
I switched to Oneplus Nord 2, but I have the same problem - I have 2 SIMs from different operators, where one has VoLTE option visible and second doesn't (while it was visible in Xiaomi phone)...
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.

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 )

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...
