"VoLTE provisioned" is off - Mi 9T Pro - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

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'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.

How to force 4g LTE on sim 1 or sim 2 as needed?

I am using the dual sim Exynos version of Note 9 and want to be able to force 4g LTE on either of the two sims as needed.
Can someone please advise how to do this on an unrooted phone? Thanks
Anyone?
I also found no solution. I think it's possible without root but no one is updating the Phone Information Apps. We need to get access at phone information 2 and not only on 1
Mine are both 4G / LTE. Inever need to switch the Sims around. Whichever I choose for days gets LTE. this is different from what I had in the Note 8. I was pleasantly surprised. Therefore it may be a settings issue for you. I have the Note 960F/D
you may try quickshortcutmaker app on exynis version and follow instructions in video
https://youtu.be/AdGAB4qRvYA
I feel like the Tasker App could handle this easily.
I dont understand the actual need.
Simply changing preferred network mode from LTE to 3G shall do to stop LTE on any sim.
I use LTE on both sims for calls
I use LTE for data on specific sim by making it as preferred sim for data.
Settings -- Networks -- Sim card manager shall help in these settings.
I am on exynos N960F Indian firmware.

You don't understand the actual need ??
So i will tell you
On my work i am located in a big Hall underground. The Provider i need down there is only coming in with -110 dB and less which is one LTE Bar. If i leave Automatic Mode it switches always in 2g Mode because of much higher Signal. So to get a nice experience and have LTE always available there is no other solution. The same kind of problem is on my other LTE Sim when on different Locations during the Day ! So i have no time to always switch sim cards so that sim2 is forcing lte !
And off course no one else knows this and so i benefit of this extremely fast connection where all others are crying because of no 4g connection

OK understood.
Did not you get one UI already which has option of LTE only selection too for network mode.
Negative. Here the German Rom (dbt csc unbranded)
Has never got LTE Only mode in the menu. This is also for all European Roms. I have had this only when using Root and Custom Roms.
Because i use many banking and streaming apps it's not possible to root this time. Even with Magisk Hide they will not work.
If i could i would have rooted long time ago. This is getting me Crazy really

Sorry but are you reading my Post?
I am talking LTE Only on Sim Slot 2 of any Samsung Phone out today. All the LTE Only Apps or the Phone Info Menu where they lead you is only working on Sim Slot 1.
I am sure there is a dial code like the one it gets you to the Phone1 Information Screen where you can change the bands. But only for Sim 2 (Phone info 2) on Samsung.
So again LTE Only on sim Slot 2 on Samsung Duos Versions is not Possible @ the moment without Root!
If there is any Dev out there you would be the first One to create an app where Phone INFO 2 is possible to change! Or just find the right hidden code for that i know it's there like the Phone Information 1
Hi,
There's an option to force the selected APN to LTE only but I don't know if it will behave like you want to.
What's great is that it's per SIM so you can try any combinaisons.
Deselect "undefined" and select only the "LTE" one (screenshots).
I expect that if it find any other bands getting a better signal than LTE, it will just let the phone loss the signal and not trying to catch the LTE one, but you can try.

Hey thanks for that. I really was in hope this could work but that would have bean to easy. Unfortunately it's not changing bands after deselecting undefined and than choose some network mode it remains to the same band but it looses the mobile data symbol (but still remains in same band).

This code and all Codes are not working on European Samsung Devices with Android 9 .
I Even Rooted my Galaxy Note 9 and all the hidden codes are Not working ! Even Samsung Phone Info App or other Apps are not working with Latest Android 9.
Only way is Root and Custom Rom like Alex Dev Rom where the CSC is Modified. There it was possible to change both Sim to LTE Only ! But as told before with Root
i loose to many services which are detected even with Magisk . So my next Phone will not be Samsung anymore because of that.

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#*#*

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#*#*.

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.

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!

No 5G connection

Just got my Pixel yesterday, noticed that I don't have any sign of 5G connection even if I have everything activated on my sim and used 5g in my area with a Huawei P40 Pro....
I noticed, when I accessed the *#*#4636#*#* menu that it shows my sim card as sim2. I know that on second sim there's no 5g and I wonder if that's the problem. If it is, is there a way I can solve it and make the phone see my sim (physical, and my only sim) as sim 1?

Yes, tested with P40 Pro, working. Here's the Pixel
https://support.google.com/pixelphone/answer/9449293?hl=en
Do you have both SIM activated? It says "Pixel 5 and Pixel 4a (5G) phones with two SIMs in use will fall back to 4G networks. To connect to 5G networks, temporarily turn off the SIM that isn't set to use data."

Nope, I don't have both SIM activated. I only have a physical SIM that's in the phone, no Esim and still, it shows it's SIM 2. That's why I asked if I could reset or something and make the only sim I use SIM1, I suspect it has something to do with the phone keeping 5G off for it.
Hello balenax
I have the same issue I am based in Kuwait. They told me that my carrier needs to do some configurations with the manufacturer (Google) and then google will enable it with a software update. The physical sim I installed says Sim 2 similar to yours and once I tell it to use NR only the Network goes away instantly. I will play with 2nd sim and tell you if something happens. Please do update me if you try something

Yes, I think it's similar to OnePlus 8, the 5G connecting is enabled only for some carriers. It's a matter of time (hopefully) but I'm afraid they won't do that for unsupported countries (I'm from Romania and Pixel is not sold here officially).
Our best bet is root and edit the carrier policy files, just as on OnePlus.
I'm not that eager to do that, I'll wait for a while and see, maybe it will be solved by Google and operators.

Yes it's the same for all 5g Androids and unsupported countries, unfortunately. It is really frustrating since the bands are supported. Only Samsung, Apple, and Huawei devices are supported everywhere since they make deals with everyone. I hope this 5g mess gets fixed soon. I am not a fan of rooting my Pixel. I am hoping it will be fixed by beg on Next Year. I just tried installing an esim but it shows up as sim 3 so there seems to be something blocking the use of sim 1. It would be interesting if someone with 5g working to give us a screenshot of the Phone info I suspect that they will be on Sim 1 . If yes is it region locked!

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.

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

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.

How can i find full fastboot ROM for NE2213 ?
I should do it with fastboot by unlocking bootloader first or using OnePlus local updater app?

I just convert my NE2215 to NE2213 without any luck
I just noticed that on NE2215 "5G Only" app shows "Voice Network Type: N/A" before and now it shows: "Voice Network Type: LTE" for NE2213
But still I doesn't the VoLTE option in settings !!
