"VoLTE provisioned" is off - Mi 9T Pro

Hi team,
This is a Global Mi 9T Pro, Miui 10.3.2, bootloader is not unlocked.
LTE 4G works, however no "voice over" - it reverts to 3G for voice calls.
*#*#86583#*#* results in "the number you have called is not connected", using both SIM 1 and SIM 2, have tried 2 different SIMs that show "VoLTE" on Reno Oppo Z and GS8. 4G switcher app shows "VoLTE not provisioned". Any suggestions on how to enable VoLTE? I have tried a factory reset once...
Thanks
(I can't add links - it's on imgur slash YFFWVNu )

I'm in Brazil carrier Tim, unfortunately there's no specific MBNLoader file for this carrier, so I selected the generic Brazil MBNLoader, it wasn't enough to turn ON VolTE in calls though, it reverts back to 3G or 2G
any other ideas?
PS found a post on another forum that says the Malaysian MBNLoader will be fully compatible with the carrier TIM on Brazil. I tried it and it worked perfectly, now I have VolTE. GG

If you are "roaming", does it switch by it self to proper MBNLoader? (if my question make any sense?)

I think what you're asking is if the MBNLoader changes automatically depending on geolocation or when a new SIM card is inserted. TBH I don't know. But if I would have to guess I'm guessing it is a setting that you select when turn on the device for the first time, and that remains selected even if you insert a new SIM card. Lemme know if i've misinterpreted your question.

ok i just quickly checked several utube videos and i see “global” device have VoLtE icon.
So I guess with global rom it will be fix bro

I have the Chinese variant of the Mi 11 Ultra and by default, I was unable to see the options to enable VoLTE and VoWifi.
If you enter the following codes into the dialer, it should work:
VoLTE *#*#86583#*#*
VoWiFi/WLAN *#*#869434#*#*
These codes disable/enable carrier compatibility check. Then go into Sim Card and enable VoLTE or VoWifi.
Since VoLTE is required for RCS in Google Messages to work, enabling this also allowed for 'Chat Features' to be ready on my phone.
Quick note: I am in Canada on the Virgin Mobile Canada network.

I did this but the icons never came up.
I'm in australia using telstra and got the china version

Did you get the pop-up stating "carrier check disabled"?
Go to settings>sim card & mobile networks>select sim 1>you should see the options here.
Hope it works!

Yeah I got it and enabled it but I can't see the volte or HD icon?

Have you rebooted?
Have you made a call to see if you stay on 4G?

I'm using EU ROM now but has VoLTE on my Chinese stock, see attached image

Even I face same problem I'm using boost sim ,I've enquares the Carrier but they said they support vote , I'm not able to get volte working in my device

Same issue. Got the Chinese variant of the Mi 11 Ultra, running 12.5.12 EU ROM and I'm on Boost (Australia). I've done all the dialler codes and still no VoLTE icon. Calls drop to 3G.

i've done a deep search regarding VOLTE on Telstra in Australia as I am facing this issue too, and I found out the following result:
This issue happened because Telstra did not share its network settings with a few companies, Xiaomi, Oneplus, and others.
On a different thread on Oneplus section, there is a way to fix it that requires root, so we add Telstra settings manually, but whenever a tiny update shows up, then we'll need to repeat it. a restart won't affect it, just an update because it replaces modified network settings file with original one.
so to summarise it, unless a software update with the new settings come up, then it won't work.
And btw, the VOLTE is working on MIUI first version of 12, and MIUI 11. but after the update, settings lost. and this is not an issue with MI 11 ultra, it is with all xiaomi and oneplus devices and a few others.
Do not waste your time on it, and just cope with what we got and be patient.

Thanks for this information, sincerely appreciated. My only concern is Telstra turning off their 3G network by June 2024. Let's hope the issue is solved before then. Fortunately my call quality is completely fine without VoLTE at the moment as reception is good. I'm sure other providers will start turning off 3G too. A very odd issue and I'm really surprised it hasn't been fixed.

Did any one manage to find a solution ?

Any solution yet to make volte and vowifi work on Telstra and boost Australia? Thanks

Yes, definitely it does
If i eject the sim and put it in my Xiaomi Mi A2 i can use voLTE

That's not what I asked. It doesn't matter if it works on mi2 or not. Did you check with your carrier if they support this phone?
Just because the phone has the bands, it doesn't mean your carrier will allow the bands to connect to their network.

I just asked from my carrier and they said we fully support VoLTE and it's enabled in my area and i should enable it from settings but i don't have any active VoLTE option in my settings to enable it!
Originally my phone is NE2210 (ColorOS) which is converted to NE2215 (OxygenOS) by reseller.
I have no idea how can i use VoLTE with my OnePlus 10 Pro

I have the identical problem with my Xiaomi 11T pro. As soon as I make a call my phone connects to "even worse" 2G ( E or H) so I can't use data at all. While the simcard works perfectly in other phone, not in Xiaomi. And I want to buy OnePlus 10 Pro but I have the same fear that 4G or 5G won't work while on the call

must be a oneplus software issue. VoLTE works for me, but VoWiFi doesn't, even though both worked on my 8T.

No. the app/setting to change that isn't available since the 9RT.

You can try the app "Samsung Band Selection" and in there go to "More Network Settings." That opens up the VoLTE/VoWiFi and which network to prefer settings on my NE2215 OP10Pro A.15.
I've been able to force NR tower connection this way to always have 5G. Although, mine isn't a converted NE2210.

Logged in just to tell you the volte option is in the Sim settings. Go to settings > mobile network then click on your sim card on top left. Hopefully this helps you out. I have attached screenshots for visual aide.

So basically NE2215 Only support US carriers for VoLTE
I hope that i can use VoLTE by some custom ROMs in future
This is the last chance for me

If you are brave and do enough research, you can try converting to NE2213, I believe that is EU version. You may have more luck. But I don't think it will help with the bands, I believe those are "hard-coded" from your base model of NE1115. (Thought you were a converted model at first, which leads to more issues.)
I may be wrong though, just trying to provide ideas.
And here's that screenshot of what it looks like for me. Note that you can also change 5G mode in settings to either SA + NSA or straight SA. I can't make calls if I choose straight SA.
It sounds like your issue is more related to your carrier, but I figured I'd share all I've figured out on this topic about this phone, just in case it may help you or someone else.

I should do it with fastboot by unlocking bootloader first or using OnePlus local updater app?

But still I doesn't the VoLTE option in settings !!

Question 5G not enabled by default

Hi there,
I apologize in advance if the question has already been answered. I searched but found nothing.
And I apologize for my English, I'm French Canadian.
I bought a OnePlus 10 Pro 12gb/256gb, model NE2213 last week.
Everything works fine except for 5G. I only have 4G (LTE) by default but with the 5G settings app I can select the NR option to enable 5G. Everything works fine and I can use 5G without any problems.
When I restart my cell, I again come across the 2G/3G/4G option only, no 5G.
The option seems to be there and functional but it does not seem to be activated by default.
Is there a solution for this?
Thanks a lot !!

Besides your APN there's not a huge amount you can do.
Is your phone an actual NE2213 or has it been converted?
If it's the latter then that could explain things..

Thanks for your answer!
This is an original NE2213 model purchased from a Canadian website. It was 30% cheaper than the North American model and I read on the internet that the bands were compatible with 5G.
It's not the end of the world because 5G is not really deployed here in Canada but I don't understand why I can activate it via the 5G settings app but when the device restarts it seems to be desactivate.

Oh ok, crazy, an EU device being sold from a Canadian resupplied does shout region change to me and would explain things..
Are you based in the EU?

No, I live in Canada and I'm on the Bell Mobility network which uses the n66 and n78 bands for 5G.
This website sells different cell phone models less available in Canada (OnePlus, Xiaomi, etc.) but sells Chinese or international versions.
Like I say I can live with it, 4G is as fast as 5G here for now, but I was wondering if there is a solution to enable 5G directly on boot.
Fun fact, when I set up the cell for the first time, it was showing 5G in the top right but when I was done with my setup and turned off the wi-fi it was rendering 4G and i can't choose 5G in the network options.

Just out of curiosity, what's your expected speeds on 5G and what are you getting on 4G..I don't use 5G on purpose. I simply don't need it as 4G gives my 250Mb +
Anyone who needs more then that needs a PC

I did a live test...
5G: 69/3 Mbps (d/u)
4G: 56/5 Mbps (d/u)
I'm at home and wifi is off.
Basicallyt, not a big difference, I'm going out today and redo a test to see if the speed is really different.

Do another test outside of my home...
4g : 61/24 Mbps
5g : 141/44 Mbps.
Big difference this time!

Question 2215 not showing 5G option in Preferred Network Type

Hi, my OnePlus 10 Pro 2215 is not showing me the option to select 5G network. I can only use 5G if I use the code *#*#4636#*#* but when I reboot it no longer connects to 5G.
What do I have to do to make that option appear?. I only can see 4G/3G/2G(auto)

Hey I have the same issue. Ever find a resolution?

I still can't find a solution to this. I think it's my service provider that needs to configure something on their side. If I put a different SIM card it gives me the option of 5G, VoLTE and VoWIFI

Ok that's very helpful. I'll check with the carrier.
