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#*#*

I recently purchased the global version of the Mi 9T Pro and I am running stock MIUI Global 10.3.2 with US T-Mobile as my provider. OOTB the phone does not have a WiFi calling option. Since this is useful to me when traveling outside the US or in areas where I have WiFi but poor cell reception, I searched for a way to activate WiFi calling on this phone. I searched the XDA sub forum for the phone, but did not find any relevant threads (so apologies if this has been posted before). I did find a useful thread started by XDA member lightcao in the Xiaomi Mi 9 sub forum:
https://r.tapatalk.com/shareLink/topic?url=https%3A%2F%2Fforum%2Exda-developers%2Ecom%2Fshowthread%2Ephp%3Ft%3D3917887&share_tid=3917887&share_fid=3793&share_type=t&link_source=app
Based on the suggestions in this thread and other information, I did the following:
1. Ensured that my T-Mobile account had an e911 address listed.
2. Enabled WiFi calling option using the dialer code provided in the thread and activated WiFi calling under the sim card settings (new option appeared).
3. Updated the T-Mobile APN with the APN types as suggested. At this point WiFi calling worked, but only in airplane mode with WiFi enabled. This was because after enabling WiFi calling, the Network Preferences defaulted to WiFi Only with no apparent option to change it (grayed out).
4. Installed QuickShortcutMaker (sika524) from the Play Store. With this app I could access the Network Preferences setting and change it to WiFi Preferred. Although the grayed out setting in the phone is still showing WiFi Only, phone is now working based on WiFi Preferred and I can see the WiFi calling icon in my notification bar whenever I have a WiFi connection.
Although this is specific to US T-Mobile, in the referenced thread people with other providers and in other countries suggest it is working for them as well, as long as the provider supports WiFi calling. Hope this helps others interested in WiFi calling on their Xiaomi Mi 9T Pro.
I used the same method a while ago in mi9t pro to enable wifi calling on O2 uk network but i didnt need to do all the other stuff i just entred the dialer codes and it started working. I think this is the case with most miui based roms because it was the same with my Mi6.
After I install miui 11 the option volte in setting Is missing.
Mi 9 Eu version .
Same here...?
At me is still there and working as usual.
I didn't touched anything before and after new ROM installation so it's really strange.
In my as well dissapear.
But call when im in 4g still working.

In mine when call change in H+ from 4g

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).
Cheers
Toscha
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 have a Mi 9T Pro with 9.11.14 weekly xiaomi.eu - ROM
I have 2 SIM-cards (2 different operators)
SIM1 for calling and SMS
SIM2 for data
Settings -> Preferred network -> GSM/WCDMA/LTE on both
Both are connected in 4G-mode
The problem is that i don´t receive sms or can´t dial out with SIM1 in that situation.
only if i disable the data-connection of sim2 or change the network mode from SIM1 to gsm/wcdma
i thought the Mi 9T Pro can handle two 4G "connections" at the same time.
Am i wrong?
Or is it a firmware / ROM bug?
can someone confirm this or i´m the only one having this issue
so for everyone this is working?

Might seem like an inane question but still have to ask - SIM1 is actually 4G enabled right?
When you have both in 4g post screenshots of *#*#4636#*#*# - > cell network info
Hi I'm having the same problem.
When I first got the phone a few months it was working fine I would see the 4g symbol on both the network strength icon. Ever since the last update it stopped, I just updated it again today hoping it was fixed but nope. I have checked settings and enabled to allow for dual 4g. One thing I have noticed is when turn the dial 4g option on and off the 4g symbols are visible on both network strength incons for a split second then it only it shows it one of them again. Is there an issue or fix for this ?
Thanks
Hey Everyone,
Have any of you managed to get WiFi Calling working on this device without root?
I'm considering upgrading to this phone from my flawless Redmi Note 7.
However, the only feature I would need confirmation works is the WiFi calling.
Is this working on this device without root?
If yes, does anyone know if WiFi calling can work on TMobile?
I am using WiFi calling and VoLTE on T-Mobile in the US. I followed the directions on the thread below. When I ran the *#*#*****#*#* code, it gives a message about VoWifi/LTE carrier check enabled or disabled. After making sure the APN was correct (especially the APN Type), enter the code until it says that the VoWiFi/LTE check is DISABLED. Once it is disabled, you should see the option to enable WiFi calling and VoLTE in the SIM card settings. It will then show the status during calls whether it is a WiFi call or VoLTE call. It may require a reboot after the codes are entered.

Thanks Man!
I appreciate your prompt and thorough response.
I haven't been able to get WiFi calling working on my Redmi Note 7 and tried just about everything. (Outside of root)
Now that you've said that I have hope I'll get WiFi calling working on the Mi Lite 9 and think I may get one!
May I ask if you're rooted?
Also which firmware do you have?
Hello
I just got this phone and set it up. Its a Global version 13.0.4 SKDMIXM.
I am on TMoblie USA - the phone is working great on LTE and 5G .
I am not able to see the Network preference under wifi calling where is can select Prefered Wifi Calling.
It appears that its running on default Prefered Cellular - because I can only see the VoLTE symbol on top.
Can someone help me in fixing this configuration to select Prefered Wifi Calling ? TIA

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.

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.
