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.
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.

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!
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.
My OnePlus 10 Pro Indian model doesn't seem to get the jio sim to enable 5g.
But my mi11 ultra works on 5g in the same area.
Tried resetting still the same
Can someone guide me if there is any process needed to be done to get the jio 5g to work
Am running the latest oxygen OS
5g takes time to get activated on the jio sim
It wasn't the phones problem
Jio 5g issue...after 4g cant connect 5g...need every time reboot to get 5g...any solution? Need help
Bro, have you found any solution yet? I have the exact same problem with my Note 12 Pro 5G. I wonder if my handset is faulty or the network.
Having same issue... WIth Jio sim.
Me too bro
