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.

FYI: The official Oreo beta build enabled Enhanced LTE in my case (my provider is Telenor DK).

Needs to be carrier enabled

Unlocked variant on t-mobile

I have an Unlocked variant which I purchased directly from Samsung.
I don't happen to see VOLTE settings in my mobile networks setting.
Is this normal? I have seen another user post a screenshot from his/her phone which shows VoLTE setting (Telcel network) which can be turned off or on,but my phone doesnt have that.
I am on Tmobile.

tmobile phones have never displayed any VoLTE icons or notifications. Its carrier dependant on if they show it or not.
Unlocked US S10s has every Tmobile feature except Multiline Digits and probably their crappy RCS service

It's also missing the Tmo Video calling.

i have t mobile and always buy samsung international phones. volte, wifi calling,
video calling, and download booster usually dont work until i change the csc to tmo. i would think the ability to do so will be coming once the phone is rooted and out for a while.

1. Normal. The icon is disabled, but the feature isn't.
2. Yes. Testing VoLTE is as simple as placing a call. Phones w/o VoLTE will drop to 3G/2G OR fail if LTE is the only signal avail.
3. VoLTE toggle is missing. I sent feedback to Samsung about this some time ago.

VoLTE not working :(

I can't seem to get VoLTE working on my RM3.
I'm with Telstra (major Australian mobile carrier) and have confirmed that they have activated VoLTE on my service.
I have ensured 'Enhanced 4G LTE Mode' is turned on in Settings.
Have restarted phone several times, reset network/sim settings etc, etc but VoLTE is still not showing or working.
Is it working for others? Any assistance you can provide please @JerryYin ?

It's strange that the VOLTE is not working, it should be supported by deafult. Which firmware you are using?

NX629J_ENCommon_V2.09 although when I go in and check for software updates it says my current version is 3.0
Have checked service menu and "VoLTE provisioned" is turned on (is there anything else I need to check in here?)
Thanks.
Edit - I've also tried a sim from a different mobile provider in my RM3 and no VoLTE with that sim/carrier either

If your operator is based on a gsm network, it may not work, I'm using China Telecom and I can get VOLTE working, it is a CDMA operator, however, my another gsm based sim card can not get the VOLTE working on NX629. I'm not sure that the Red Maic 3 can woek on all operator and all get the VOLTE function. Sorry for that.

But VoLTE does work in Australia with all of our major mobile networks so that shouldn't be the issue?
Could it be that our two main carriers both use LTE Band 28 for 'best' 4G connection and the RM3 that I was sent does not have that?

Can any other RM3 users please comment on if they have VoLTE working or not?

No Volte on UK's EE network.
On top of that, I can't even use "enhanced LTE" option, if I turn it on I get no caller id (when someone calls me I only get unknown caller instead of the name or number of the person).

In india Global version VOLTE is working perfectly for both sims on global Rom as well as Chinese ROM. You dont ses VOLTE but HD icon next to signal bar in CN rom. On vlobal rom when you are calling someone you see HD.

Interesting. Thanks for the info.
Firstly, my sim settings look different to yours, not sure why Nubia has made this setting different in roms for the same phone?
Secondly, I managed to have VoLTE work today with a different mobile carrier sim - I tested and 4G was remaining on during calls! But no VoLTE or HD symbol was evident in the notification bar along the top. @JerryYin can you please confirm if the VoLTE symbol should show on RM3 software? If not, can this be added in a software update please.

check in the calling screen HD should appear.

Yes it does but I really thought the VoLTE symbol should appear in the notification bar?
On my OnePlus 6T, the VoLTE symbol is permanently displayed in the bar when VoLTE is turned on.

Nubia's way of VOLTE = HD

voLTE does work on EE. If you have enhanced LTE option turned on and make a call I think you'll find that the call is made via 4g. It also has WiFi calling on EE which can be enabled through the phone app.
Like you say though, using voLTE and WiFi calling does render incoming calls as showing unknown numbers. I'm still trying to figure out why it does this, it's obviously something to do with the IMS settings as it's not optimized to work on EE's network.

Please let us know if you figure it out.
WiFi calling would be great for me, as cellular signal is poor in my area.

Call your network provider and ask for the settings to be pushed to your phone.

They can't for some odd reason. maybe they're clueless

Question Not seeing Network Preference under Enable Wifi Calling Tmobile USA

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

Perhaps you might want to give this a try-

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.
