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'm currently using the MIX 2S with MIUI 10 in combination with O2 / Eplus. The provider does defiantly support the WIFI Call, but MIX 2S does not support it.
What's about MI 9. Does it support in combination with the actual MIUI ROM the WIFI Calls?
Yes, using it with Telekom Germany (D1).
Just enter *#*#869434#*#* in dialer and enable it in phone settings.
Thank you. It's the same approach for Mix 2s, but it' not working with O2/Eplus even if the provider does support the feature. So I assume Wifi-Call wil also not work on Mi 9 with O2/Eplus.
wifi calls working great with SFR (france)
WiFi-Calls on Mix 2S and O2/Eplus are working also great with LineageOS 16.0 too, which is available for MIx 2s. But it's not working with MIUI.
I'm sure it is the same situation for MI9 WiFi Calling. Or have somebody managed to enable MI9 (MIUI) Wifi-Calling with O2/Eplus?
Wifi calling on o2 Germany works after you enter *#*#869434#*#* in the dialer and then check sim settings and enable there. However it is quite spotty, sometimes it does not register after connecting to WiFi or loses the connection after some time, but it definitely works, I performed several calls in flight mode and only WiFi enabled.
Only after the most recent OTA update (July, 2019). completely stock, brand new device. put in already activated Verizon Sim, picks up LTE signal and registers IMS and VoLTE works fine. the only issue I have is that IMS is not registered after rebooting, needs get into airplane more and back to register, but afterwards works fine, even after losing signal. It was NOT the case before, looks like Samsung finally added VoLTE to dual-sim CSC in last June/July updates. the second SIM is Project Fi data only SIM, also works fine and looks like registered IMS, but since it is data only, can't try VoLTE.
I also noticed same in my SM-N960F/DS note 9. stock rom can registered IMS hence VoLTE now. but I keep have problem with SM-N960F where it only picks up LTE signal after rebooting, but not after having lost signal or out of airplane mode. hence decided to try a SM-N9600 instead, and it worked out.
Now I don't have any reason for Note 10 anymore....
Better samsung added VoLte support ON N9600 otherwise I made my mind to move on with Different OEM ! I was gave up with Samsung for having region Restrictions!
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.

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

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!
Did anyone manage to get VoLTE and VoWiFi to work with any EU carrier and SM-G7810? I have the options enabled in settings, but, unfortunately, I think the phone does some sort of carrier check(my carrier is Orange RO). As it seems that many people in Europe bought this phone as it has 8 GB RAM and it tends to be rather cheap, has anyone been able to get VoLTE to work? The bands are okay, and in my case I know it's not a carrier issue(I had Xiaomi phones which were also not supported officially by the carrier but I called them once and told asked them to just enable VoLTE and VoWiFi for me and from that point on it worked after I disabled the carrier check on the Xiaomi phone). In my area I have poor 3G and 2G reception, but very good LTE band 20 so VoLTE is quite important for me.

Hi, do you fix it ? I have also the same problem.
After clearing Carrier Whitelist VoLTE is working for me on DiGi and Vodafone Romania . IT also works Digi 5G that doesn't have extensive coverage .
What strangely doesn't seem to work is B3 2CA on Vodafone , strangely it works B3+B1 but not B3 intraband.
Also the good thing about the phone is the existance of B20 that really works even the phone is HK, China model

Hello. Can you please tell me how you cleared Carrier Whitelist? I can't find any information online. Thank you.
Search XDA as it is in the service menu and it is used generally for 5GCarriwr Whitelisting.
Can't make wifi calling work on rogers canada using Redmi Note 10 Pro Global Version. Was talking to Rogers tech support, to their credit they tried to activate this on my new Redmi Note 10 Pro Global (Tier 2 tech support), adding imei nr to whitelist, and entering RWC codes but to no avail.
I used these codes to bring up the options in the phone, and "activated" them (volte, wifi calling, prefer wifi calls).
VoLTE *#*#86583#*#*
VoWIFI *#*#869434#*#*
Rogers Tech prompted me to enter code: *#243203855# which is supposed to switch phone to RWC, but the MMI fails. At this point tech support ends, nothing else can be done (they say only phones purchased through Rogers are supported, plus all iphones, google, and samsungs).
So, I am wondering, is there a workaround that Rogers doesn't tell?
