Hey guys,
yesterday I got my new Mi 8 <3 It's really nice...
I wanted to check if I can use wifi calling, but there is no option for it in settings. I can search for it but there is only text as you can see in the screenshot.
I checked the "hidden menu" under *#*#4636#*#* but the option is greyed out, too.
I'm living in Germany with Vodafone and wifi calling is included in my plan.
Any hints? Is wifi calling working for you?
Thanks
I think the Mi8 is not supported by Vodafone.
I don't get it :/ Other Xiaomi phones are working, too. I thought Xiaomi have to implement the profiles? I don't know why this is always so hard, Android does support VoWifi since some major versions natively
It was one point, why I bought the Mi8 instead of the OP6. I hope it will get it fast

Hey man thank you very much for this. I tried it and it seems that is working. Νow in the signal bars I have a HD which I guess is because of Wi-Fi calling.
Hi Baddevil2!
Did you eventually manage to get WiFi Calling working with Vodafone Germany?

No, "HD" usually means VoLTE which is a completely different thing. Could you please try to enable flight mode and after that ONLY enable WiFi? If you are still able to make / receive calls, than WiFi Calling is working.
Tried build.prop change, Wifi-Calls enabled and preferred *#*#4636#*#* shows the switch enabled, but (three dots - IMS status) shows VoWifi "not available". VoLTE works same as before (without build.prop tweak). I checked both O2 and Vodafone Germany.
Seems there is no solution for VoWifi at the moment.
Come on, don't destroy my hopes Too bad...

My friend I don't think that the Wi-Fi calling works like that. The phone must recognize that you have sim card in your phone. I think that If you enable the aeroplane mode the phone doesn't recognize the SIM card. I am not 100% sure thought.
Yesterday I tried it with latest Xiaomi.eu rom and Magisk Module (to write build.prop entries).
I can enable VoWIFI in settings but if I try to call someone from wifi I only get an error message.
Very sad that it not work
Did anyone get this working?
I'm using Mi8 in UK on "Three" & "EE" - neither support the handset.
Can it be forced to work? Point me in the right direction if possible. Thanks
On MIUI ROMs it's not possible to get it to work. I installed Pixel3ROM some minutes ago and try to enable it there
Please keep us updated!
I didn't know it is possible to use different types of ROM on the phone.
Of course it's possible, but at the moment it still doesn't work Maybe I have to try another ROM
I'm on eu rom. when i install volte enabler magisk module (in repo), i got wifi calling feature in sim settings which actually works
On Xiaomi.eu ROM? I get Wifi-Calling switch, but phone does not register with IMS (Vodafone Germany).
Can you provide screenshot of ims status?

Just in case you do not know it, the carrier that you use, need to support it in general, and the carrier also have to decide that they want to support on that phone model.

Is the menu inaccessible/hidden entirely without carrier support? I can find the shortcut to "Enhanced 4G LTE" by searching the settings menu, but when I try to follow it I end up with the normal network settings (without the Enhanced 4G LTE option)
My phone is the TA-1004 version

*#*#4636#*#* key combo will get you access to enable VOLTE/Video calling over WIFI.
Be careful of what you change.
Hello,
Thanks for sharing that I fo, I know that secret code but don't stay on VoLTE, seems as carrier have to enable that service on sim card, and they make available this services only on Samsung S8, Samsung S8+ and Xiaomi MI6. They are still on test with VoLTE
I think it depend on carrier.
I have two carrier, one doesn't have VoLTE and another have
In Cellular network settings, you can see one have "Enahnced 4G LTE Mode", but another not.

Hey guys, so just curious, is there a way to force WiFi calling? My signal sucks in my house but my WiFi is awesome. Supposedly the device will prefer mobile signal if it is strong enough, but you can't physically choose WiFi calling to be default.
If anyone knows anything, let me know. I'm on EE.
when at home if you want wifi calling to kick in instead of celluar, do the following but it is a pain to remember to do it each time
Turn on Airplane mode
Turn on Wifi
Turn on Bluetooth (if you use bluetooth)
when you leave house, just turn off airplane mode
You can set it to prefer WiFi instead of mobile network, I don't know if it really works, my p20 pro is choosing WiFi always, even if both of signals are 100%

Call carrier support / Check firewall
I had to call vodafone. After some time they decided to disable wifi calling feature for my account for a couple of minutes and re-enabled it. That worked for me. My phone instantly logged into wifi calling again.
Also make sure that outbound connections to port 500/4500 are not being blocked by any firewall/router.
How do you set Wifi to be preferred instead of cellular?
Hi, guys.
Just wondering if any of you have working VOLTE/WIFI calling on your Pixel 5.
I'm on Vodafone UK and none of these are working, I don't get the options for the two in Network settings.
Apparently, they are not provisioned ATM.
Have you had more luck with your operators?

Yeah, I had a feeling going with Vodafone is a mistake...
Working here with O2. They have a guide on the Vodafone website for the Pixel 4 so can't see why it doesn't work with the 5. https://deviceguides.vodafone.co.uk...ress the phone icon.&text=Press Wi-Fi calling.
Well, it's Vodafone. Apparently one of their geniuses has to add a line of code somewhere..
Anyway, the guide for P4 asks for activation from within the phone app's settings and the Wifi calling/Volte settings are missing from there on the Pixel 5.

Wifi Calling
works on my P5, also a 3 user
option is found under Settings, Network and Internet, Mobile Network, Advanced, Wi-Fi Calling
I'm on Vodafone and I don't have settings for WiFi calling either. Funnily enough when I got text message from Vodafone to download internet settings they didn't even have the pixel 4a/ 4a 5g or 5 on there.. so that's probably why people on Vodafone can't enable it because Vodafone themselves haven't added the phones on for WiFi calling

Check out this thread on Vodafone forum, will try it myself and see if it works

Okay so update for Vodafone users, I got it working.
Following the second link above, 1. Go into Vodafone app and turn off WiFi calling, restart phone. 2. Go back into Vodafone app and turn back on WiFi calling (wait for 3/5 minutes and then restart phone again (you should receive a text from Vodafone saying it's enabled on your account). 3. Go to call app > settings> calls>WiFi calling>enable.
It also shows on networking settings in advanced now too.
Now I'm connected to WiFi calling, hope this helps Vodafone users

It works for me now. Just try the following:
On MyVodafone app, disable wifi calling and immediately restart the phone. Then enable it again and immediately restart the phone. The Wifi calling settings should appear on Settings/Network and Internet/Mobile network (Vodafone)/Advanced.
At least they have in my case.

What an arse i am, turns out the other caller was using their phone on speakerphone, made a few calls since and VoLTE is working just fine on BT Mobile.
Neither is working for me as well, but was working fine on my old phone.
What I noticed on my device is that it came from Google with the "KDDI only" build on it(see https://forum.xda-developers.com/pixel-5/help/kddi-variant-t4178033), which I suspect might be related to the issue.

ok i just quickly checked several utube videos and i see “global” device have VoLtE icon.
So I guess with global rom it will be fix bro
I have the Chinese variant of the Mi 11 Ultra and by default, I was unable to see the options to enable VoLTE and VoWifi.
If you enter the following codes into the dialer, it should work:
VoLTE *#*#86583#*#*
VoWiFi/WLAN *#*#869434#*#*
These codes disable/enable carrier compatibility check. Then go into Sim Card and enable VoLTE or VoWifi.
Since VoLTE is required for RCS in Google Messages to work, enabling this also allowed for 'Chat Features' to be ready on my phone.
Quick note: I am in Canada on the Virgin Mobile Canada network.
I did this but the icons never came up.

Same issue. Got the Chinese variant of the Mi 11 Ultra, running 12.5.12 EU ROM and I'm on Boost (Australia). I've done all the dialler codes and still no VoLTE icon. Calls drop to 3G.
i've done a deep search regarding VOLTE on Telstra in Australia as I am facing this issue too, and I found out the following result:
This issue happened because Telstra did not share its network settings with a few companies, Xiaomi, Oneplus, and others.
On a different thread on Oneplus section, there is a way to fix it that requires root, so we add Telstra settings manually, but whenever a tiny update shows up, then we'll need to repeat it. a restart won't affect it, just an update because it replaces modified network settings file with original one.
so to summarise it, unless a software update with the new settings come up, then it won't work.
And btw, the VOLTE is working on MIUI first version of 12, and MIUI 11. but after the update, settings lost. and this is not an issue with MI 11 ultra, it is with all xiaomi and oneplus devices and a few others.
Do not waste your time on it, and just cope with what we got and be patient.

Thanks for this information, sincerely appreciated. My only concern is Telstra turning off their 3G network by June 2024. Let's hope the issue is solved before then. Fortunately my call quality is completely fine without VoLTE at the moment as reception is good. I'm sure other providers will start turning off 3G too. A very odd issue and I'm really surprised it hasn't been fixed.
Did any one manage to find a solution ?
Any solution yet to make volte and vowifi work on Telstra and boost Australia? Thanks

It appears that its running on default Prefered Cellular - because I can only see the VoLTE symbol on top.

Hello, I'm using a 11T Pro Dual SIM India model with India SIM in Slot 1 and TMO SIM in Slot 2.
I have not found the specific setting to make Wifi Calling "Preferred" but, my phone does indicate Vo WiFi even when I have Wifi connected and Mobile Data turned on too once Wifi Calling is enabled as below.
Apparently the Voice Over WiFi Settings (at least here on my phone) only show up for SIM 1, does not show for SIM 2.
Attached are sample screenshots where the Settings are under SIM 1.
Steps to get there-
Settings > SIM cards & mobile networks > Click on SIM 1
All the way down, last Setting is "Wi-Fi Calls" to enable "Make calls using Wi-Fi".
Hope this helps.

Operators can disable this menu if they want to lock you onto Wifi preferred or cellular preferred. Does this only happen with this phone or does it also happen with the SIM in another Android phone?

There's a possibility of TMO-US not supporting WiFi calling on the Xiaomi 11T (Global), perhaps.
Although, I have been using various Unlocked phones (Nokia & Samsung) on TMO-US for the past few years & have practically never had issues with WiFi calling on any. Shall have to test it once I'm back. Won't be for some time.
Is your phone on the latest firmware? Try updating it to check if there's a new update available
which hopefully can solve your issue.
Couple of options to test, in case you have not already tested them-
a) leave WiFi Calling Enabled then disable the VoLTE feature and check if WiFi calling works?
b) disable Mobile Data, WiFi Calling enabled with WiFi connected and check if WiFi Calling works.
c) some users have had to ensure their E911 address is correctly in place on the TMO account too.

Operators can disable this menu if they want to lock you onto Wifi preferred or cellular preferred. Does this only happen with this phone or does it also happen with the SIM in another Android phone?

I move from a One Plus 6 - it had the options

There's a possibility of TMO-US not supporting WiFi calling on the Xiaomi 11T (Global), perhaps.
Although, I have been using various Unlocked phones (Nokia & Samsung) on TMO-US for the past few years & have practically never had issues with WiFi calling on any. Shall have to test it once I'm back. Won't be for some time.
Is your phone on the latest firmware? Try updating it to check if there's a new update available
which hopefully can solve your issue.
Couple of options to test, in case you have not already tested them-
a) leave WiFi Calling Enabled then disable the VoLTE feature and check if WiFi calling works?
b) disable Mobile Data, WiFi Calling enabled with WiFi connected and check if WiFi Calling works.
c) some users have had to ensure their E911 address is correctly in place on the TMO account too.

I had a working One Plus 6 - so I know TMO has VoWifi - I use it a lot due to poor reception at home .
The current workaround to force VoWIFI is
Turn On Airplane MOde
Turn ON WiFi only
then it works in VOWIFI with out any issues
I know I am missing a menu Item that can toggle this setting . I would prefer having that setting but its not a breaker for now . The phone works with all the Network features of TMO , LTE , 4G , 5G etc . No visual voicemail thats all.
Thanks

Thanks - this code is what got me to where I am now . I think from other articles - the mbn config may require some tweaking - but it refuses to give me access to it when i use *#*#663368378#*#*
Same access issue here too.
Wish you luck.
Pinging to see if there is a soln. in future.
