Here also. As a workaround you can disable VoLTE Carrier check (*#*#86583#*#*). This works at me.
For me it appeared in the settings with the update, but still cannot activate it
I have the same problem pls try
VoLTE *#*#86583#*#*
VoWIFI *#*#869434#*#*
It's work

For my case, VoLTE was operational before the upgrade (using 10.3.11 international version on my Mi9T in Vodafone GR). An icon was displayed for VoLTE on the carrier signal in my mobile's screen when it was connected in 4G.
Now it does not work anymore (upgraded yesterday to MIUI 11.0.1 international version, no icon when connected in 4G networks and actually drops to 3G when performing a call so it gets circtuit switched and not IP based via IMS). Of course it is not a matter of settings to disable carrier checks (as already done/undone several times, reboot etc, since it was in disabled state already and the settings are there to enable/disable VoLTE and VoWiFi).
VoWiFi still works but only when using Vodafone's application for WiFi calling.

Contact Vodafone GR (even their website and use chat to request VoWiFi/VoLTE service for your mobile number), they will handle it. Meanwhile you can also use *#*#VOLTE#*#* and *#*#VOWIFI#*#* settings to check that are in disabled state. You should be able to see VoLTE and VoWiFi settings (enable/disable etc) in your Sim cards & mobile settings (pick your Vodafone SIM settings then).

I have Vodafone in Italy the same problem but I wouldn't know how to insert the writing in the numeric keypad I just slip the symbols.
There're characters below the numbers.
Then *#*#VOLTE#*#* is keyed in as *#*#86583#*#*.

Mi 9 miui 11.0.5 volte vowifi dual 4g options missing
Hello ,
Mi 9 bought from Greece you.gr after miui 11 android 10 upgrade, volte vowifi and dual 4g options missing !
Also sms app fails to send sms if the Use GSM alphabet option is enabled!
*#*#VOLTE#*#* and *#*#VOWIFI#*#* solves the issue! i don't no if there is similar code for dual 4g enable or it not needed and just works!
I am using only one sim card cosmote, so i can't check the dual 4g!
Thank u
Dialing the code "*#*#86583#*#*, the message "volte carrier check disabled" is shown. Then I can toggle the VoLTE option in settings, and it works when making a phone call. Look at the screenshots I attached.
Phone: Xiaomi Mi 9
Contry: Italy
Carrier: TIM

Just returned from a trip to Thailand. VoLTE and ViWiFi work on both sim cards, Telekom (DE) and AIS (TH).

Edit : VoLTE is activate...but don't work.....
Hi, I got a Mi 9 SE. I activated volte and wifi call with the codes under MIUI 10 some weeks ago. Volte and Wifi Call worked like a charm.
Now I received the Miui 11 update some days ago. Unfortunately Volte and Wificall stopped working.
Reentering the codes worked, but with enabling Carrier check again ...
Strange thing is that in settings the option to enable Volte and wifi call is still visible and activated - but I can't see the volte logo und it obviously doesnt't work ...
I read in another forum to do a factory reset might help --- but it got a lot of installed apps etc and I am not willing to reinstall everything ...
Anyone an idea how to reactivate?
Thanks for help!
Hello,
I recently read about the possibility of using WiFi calling in India and initially it will be available for k20 pro users. Can anyone help how to enable this feature in K20 pro.

Step 1 Go to your dialer and type in
*#*#4636#*#*
Scroll down until you see WiFi calling provisioned if you can't toggle to on proceed to step 2
Step 2 Return to the dialer and type in
*#*#869434#*#*
You will get a message flash up on the bottom of your screen
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#*#*
Hi,
I do not get VoLTE working on my Redmi 4X (last official ROM MIUI Global 11.0.2 Stable NAMMIXM). I tried with two SIM cards (1x Telekom Prepaid, 1x Klarmobil Telekom). Both of them support VoLTE and VoWifi in my father's Redmi 6A, so my 4X is the culprit.
I entered this *#*#VOLTE#*#* code which disabled carrier check and enabled VoLTE in the menu (see screenshot). But whenever I start a call, the phone switches to 2G or 3G.
Should VoLTE work in the 4X or not? I read some information, that Xiaomi morons broke this functionality with an update and never repaired it, but don't know whether this is true.
i have a xiaomi mi 9 phone with xiaomi.eu miui 12 operating system
lately i have enabled volte and vowifi and used a shortcut to mbn loader to change the settings that allow me to use volte and vowifi
the problem i am facing is: vowifi will connect only while on wifi 5 or wifi 6 networks (802.11ac/802.11/ax)
if i connect to wifi4 which is 802.11n, it wont connect to vowifi. other phones like huawei p20 pro do.
is there a way to modify this behavior to make the mi 9 use vowifi on wifi4 networks?
update:
i have found that if i am connected to a 802.11n network and i toggle on the wifi hotspot on my mi9, it will enable vowifi and keep it on even if i toggle off the hotspot. it remains until i disconnect from that network
I'm currently residing in India and my network provider supports Volte but it isn't enabled on my device i.e. Xperia 1iii is there a way to enable Volte and WiFi calling on my device?
