Just wanted to share my experience with WiFi Calling. I am in the US on T-Mobile and WiFi calling has been working for me surprisingly. VoLTE has also been working wonderfully. I've tested this on a Global Mi 9 running Stock and the Xiaomi.eu rom.
Enter these codes into the Dialer to enable the options in Settings. (Settings < SIM Cards & mobile networks < Sim Card Settings < VoLTE Enabled/Make Calls using WLAN)
VoLTE *#*#86583#*#*
VoWIFI *#*#869434#*#*
Things should work after you enable the two options. This depends on whether or not your carrier supports it and your e911 address set (US only?).
Some issues you might run into is that the option for Network Preference is greyed out and you will unable to change that option. I've had some success if you disable it and re-enable it and click on that option really fast, it will go through. When you first enable VoWiFi, it is important that you get into this menu and change it to WiFi preferred or WiFi Calling won't work.
UPDATE:
Manually creating your carrier APN worked great for me. Been testing it for about 2 weeks and I haven't had any issues with VoLTE/VoWiFi. For example, for me on T-Mobile, I created a new one with the following settings. The important part I'm guessing is the APN type. Also make sure that your carrier has enabled WiFi Calling on their end as well.
APN: fast.t-mobile.com
MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
MMC : 310
MNC: 260
APN type: default,supl,mms,ims,cbs
APN protocol: IPv4/IPv6
APN roaming protocol: IPv4/IPv6
On a side note, since you're on T-Mobile US, are you getting LTE+? I was showing LTE+ on my Mix 2S and Mi 8, but doesn't show up on my Mi 9.
Can verify, works with Chinese Mi 9 8GB 128GB version. I'm also on T-Mobile. Now there is "HD" written on the signal icon.

It does when I'm outside. RN it isn't showing tho, I'm in the basement. I'm pretty sure I've seen it before when I'm on the bus or something
Also works in Netherlands with Vodafone

Worked like a charm on Romania's Orange network. Both VoLTE and VoWiFi seem to work well.
Thank you for the tip.

It's a carrier specific option. So go to phone-> settings-> Sim cards &.....-> Orange and should be the last two options.
Hmm...I've activated both too but only get the volte option, no wifi calling toggle switch. Tmobile USA running no root, stock miui 10.2.3. Did anyone on tmobile USA get wifi calling to work? Also, if you did, does it also activate wifi texting?
Update: guessing the volte doesn't require a restart but wifi calling requires a restart. To those who run into the same prob as me.
Ídem here, no volte options, my carrier support it and works on a s7 edge, any ideas?

After update to Miui 10.2..24.0 options for VoLTE and VoWIFI appears in menu and i can activate both.
unlike you, since the last update 10.2.24.0 I lost the option volte/vowifi, when I try to reactivate it, the phone tell me it's enabled for the SIM 2 but I have no sim two,
if i swap the sim card it tell me activated for the sim 1 ...
Same here, after the new update 10.2.24.0 i have the same message like you.

I activated volte and wifi calling, but when I go on flight mode and activate wifi, wifi calling is not working and there is no sign in status bar too. I am Vodafone Germany and on my Samsung it was working.
How did you get it working?

Did a quick test on mine (T-Mobile/Germany) and it's working. I just used the dial-codes and enabled wifi calling. Had to change the preferred connection type to wifi-prio though - wasn''t working with cellular-prio and flight mode before.
It works!

Download a signal app from the Play Store and make a phone call. If you still have 4G when making the call Volte is working. If the signal drops to 3G after the call connects Volte is not working.

I did It and volte is not working...
I have a Mi 9 global version running the latest stable global Room. I'm trying to turn VOLTE on, but I'm nota being sucessfully.
I've tried enable It via MCC code (*#*#4636#*#*) but It doesnt work. The option to enable VOLTE os greyed out.
How can I enable It? My old s7 suport VOLTE with the same sim card.
Hi,
I am using Mate 20 Pro (LYA-L29) in US and the firmware is 232. I am pretty sure that my carrier (not U.S. carrier) supports VoWifi and I used it on this Mate 20 Pro before while I was not in U.S. After I moved to U.S., I also updated the firmware and the Wifi Calling option has gone since then. To double check what is the cause, I inserted this SIM card into an iPhone and Wifi calling was available and worked well. Therefore, I think it is a problem of this phone.
Does anyone encounter a similar problem?
Thanks!
Different networks operate WiFi calling in slightly different ways. I know that my Mate 9 didn't support WiFi calling in the US but has done in other places without issue.

I don't quite understand why wifi calling depends on the physical place. Say I set the phone to airplane mode and connect the phone to different wifi routers in different places. The wifi standard is always the same and the phone may not be able to tell where it is.
VoWiFi and VoLTE (WiFi and 4G calling) are network and handset dependant. If a particular network hasn't authorised a particular handset, or if that handset doesn't have the specific settings needed for a particular network; then VoWiFi and / or VoLTE won't work.
I installed "Network Cell Info" to check the status of Wifi Calling and the availability of Wifi Calling is No. I notice that the devices prior to mate 20 pro have a secret menu and there is a switch to turn on the availability of Wifi calling. However, the secret menu code does not work anymore in my mate 20 pro.
This is so fvcked that despite my carrier (from which I GOT THE DAMN PHONE) supporting VoWiFI (I had it working on my S7Edge before this) and despite VoLTE working on my Mate 20P, they just won't enable it on Mate 20P.
Guess what...it DOES work on P20/30 Pro, from day 1. Go figure.
Also...got a SIM from a different carrier...bam, VoWiFi working on mate 20P.
This is madness....I'm running out of hair to pull.
PS I went as far as installing Nova launcher so I can create a widget to ENABLE VoWiFi (which normally does not show up in the Settings) but of course it does not do anything because the carrier did not enable it for the phone.
i have same problem in Israel carier
i have the volte switch but its not working.
other carier its worked automatically but their internet i cant watch youtube at 1080p

My situation is exactly the same. I have a switch for VoLTE but not for VoWifi. I also tried Nova launcher, but it did not work.
The strange thing is that the sim + mate 20 pro works in one place, but not in the US.
I really need WiFi Calling in order to reasonably use this phone for calls from my house due to a poor Network signal. There is no Wifi Calling option in Calls -> Settings or in Settings -> Network & internet -> Mobile network anywhere. Also when I do *#*#4636#*#* and go into Phone information Wifi Calling Provisioned option is grayed out.
Nope. Last time I saw wifi calling available was on the XZP. Wasn't an option for the XZ3, and still not an option for the Xperia 1. Try giving tmobile a call or maybe sony support and ask if they can add wifi calling support.

Which frimeware is that ? Is that US unbranded
Nope, no wifi calling for me. I originally had the J9110 model (international dual sim, hong kong) but i recently flashed it with the US firmware. No dice, unfortunately. But since changing to the US firmware, I now get VoLTE and group message in Android Messages. It's a start.
Ya VoLTE is working fine and appears as provisioned in the hidden menu. So it seems like I will have to do something similar to what I did on the XZ Premium in order to get WiFi Calling...but I will wait until there is a DRM backup process.

I see the same thing as you. How did you do it on the xz premium?
I had to root it and flash a zip that someone made for it, it might be possible to use the same zip but I'm not going to root mine until there is a DRM backup method. I barely every talk on the phone without LTE service so it's more so just really annoying not having WiFi Calling. I think a bunch of people were using the same zip for the 2017/2018 xperia phones to get it working.
I have XZ premium and XZ1 and wifi calling option is displayed when I use the Jio sim but not displayed when using Airtel sim (using Airtel broadband), so our phones do have wifi calling facility but working only with Jio sim, although Sony is not shown in the compatible phones list. I am in India.
That also stresses me out on My Xperia 5. Don't know If You talked about My Zips for VoLTE and the other Features but i didn't get it to work actually on Android 10. Possible that i just don't have the right Firmware atm (Customized EU / My Devices Firmware isn't Out yet), so i'm using Custom UK Firmware but that should also work... I'm a bit confused so i switched to GSIs which Made it even worse... Looks like we should start making Custom Vendors for our Xperias since the Methods changed over Android 7-8-9-10
Can you flash the dual sim model to work with a single sim firmware and does Wi-fi Calling Work later?
yes, that's what i did with my xz3. volte works with tmobile, but not att.
Hi all,
I hope this is the right forum for this question and, if not, I apologise.
I live in Australia. My telephone provider, Boost Mobile, provides VoLTE and VoWIFI capabilities. On my previous Umidigi F1 smartphone I was able to use both, but when I moved the same SIM card on my Mi 10 Pro I couldn't find any settings, although I know the Mi 10 Pro has VoLTE and VoWIFI capabilities.
I cannot see anything where to activate them, no settings. I tried these codes as recommended in some posts on here, but they seem to do nothing. As soon as I press the star and the end of each code, they simply disappear and no message is visualised on the screen, neither any option appears in the SIM settings.
To unlock VoLTE: open your phone app and dial *#*#86583#*#*
To unlock VoWifi: open your phone app and dial *#*#869434#*#*
I have a MIUI global 11.0.4.0 (QJAMIXM)
Do you any suggestion? Thank you in advance!
Cheers,
G.

Has anyone been able to successfully activate vowifi with the global Mi 10 Pro?
I can disable WiFi carrier check using *#*#869434#*#* which gave me the " Make calls using WiFi" option in mobile network settings. Although the option is checked, it doesn't seem to be working using a Telstra SIM (which has WiFi calling perfectly with an iPhone 8) .
Dialling *#*#4636#*#* reveals that WiFi calling provisioned is still disabled and greyed out.
Any ideas?

Me too, i can't see volte icon too, never seen, instead it works with my operator on every other phone i have
i know this is an old thread but wanted to say thanks, i have a mi 10 ultra and im on Telstra (Australian Network) using the 2 codes in the OP both came up with a quick popup after entering saying "disabled volte/wifi carrier check" and now in the sim options both the volte and vowifi options show up and when enabling them the vowifi icon shows in the top so thanks!! (i chose to prefer wifi network over mobile networks in the vowifi options) EMUI version in screenshot.
When I use the codes in the OP I also get voWIFI and voLTE in the status bar and they work, but I lose caller ID so I cant see whos calling me.
I m in the UK on Virgin, I moved from Vodafone a few days ago to Virgin, on Vodafone both voWIFI and voLTE worked, but I didnt get the voWIFI and voLTE signs in the status bar, I also got caller ID.
The weird thing is that Virgin is a MVNO that now uses Vodafones network.
WIFI calling, video calling and voLTE are still greyed out in MUI settings even though I can now get them, all very strange.
I think you are all misunderstanding the technology.
There is a few dependencies. Signal availability, Signal strength and MOST importantly the other caller MUST be the same and on the the same network provider.
Now, I can't speak for other countries mainly because I don't live there, but here in the UK VOLTE will be either "4G" or "4G+" where the signal bars are displayed. By now the majority of the UK will be "4G" which technically IS VOLTE because the technology is a data carrier with a voice protocol strapped to it. This is why the provider must be the same for BOTH callers or it will fallback to 3g for the call for BOTH callers.
4G+ is LTE-A (LTE ADVANCED) is a dual band version of 4G which will attempt to use one band for keeping data alive and the other band for VOLTE. Again, this is dependent on the same factors as 4G with the same fallback rules.
5G is technically 'the standardisation' of all providers so the signal doesn't fall back.
I am in the UK. Stock Mi10 5G on a Giffgaff (O2) simcard. I can get all of them.
I think you have missed the point I was making - the same phone on Vodafone voLTE and voWIFI works, but I change to an MVNO that uses the same Vodafone network, I use the same phone, but suddenly neither works. There is clearly something on the carrier side that they do to enable or disable registering IMS, my previous Le Max 2 was voLTE and voWIFI compatible yet I could never get it to work on Vodafone even after having a massive dispute with them about it, I concluded then that there is somehting their end stopping it from working, my expereience above seems to confirm this. Quite why they designed voLTE and WIFI like this I dont know - they should just work just as 2G and 3G calling do.
I have never heard that the caller must also be on the same network, that does not sound right to me and indeed when was on Vodafone I could call non Vodafone users and still get voLTE.
Because Vodafone aren't obliged to share their full network with other providers like vermin media. Although you think they are one in the same they aren't. Vermin rent from Vodafone so it is a sub system. Why would Vodafone give anyone else Admin over their network?
Regardless of whether you think you have full 4g at both ends if the other caller doesn't for whatever reason you get the best that they can do and nothing more. There is no upscaling. That's why you need to both be on the same network/provider.
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

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 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.

Interesting to find out what these options do.
For some reason, non of these codes work for me now after doing the region change a couple of times.

We keep telling people - you gotta unlock every time you change region and even then the unlock lasts a fixed amount of time ex. 24 hours before it locks itself again

Unfortunately, the tool no longer works for me to unlock, the codes don't work. I'm stuck.

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

Did you have the call recording option right after you switched region? I changed to Singapore Ex right after I got the phone, didn't see that option. Then I upgraded to ColorOS11, still did not find that option.

You have to give permissions to 'Recording' app, then open enable it in 'Call Settings'

Do you mean recorder App?
Already given all permission but still no call recording option, and the recorder only has cloud sync on its setting
