Phone operator not supporting wifi call. Can I unlock it? - Xiaomi Redmi Note 7 Questions & Answers

Hi, so I know you can enable wifi calls on your Redmi note 7 phone, but that doesn't mean wifi call will work. I believe phone operators needs to support your phone for this. I use "Onecall" which is based in Norway. They only support iPhone's, Samsung phones, and a few huawei phones.
Is it still possible to make this work? I really do need wifi call, and now I'm considering getting a phone that truly supports this feature in Norway.

I think it's an IMEI based feature,for example here in Italy with Vodafone just some devices can use VoLTE and some of them needs to be sold by Vodafone with a branded software, so the VoLTE will work only on that IMEI, i don't know how your carrier work but i think it's something like that.

Those commands is just so that VOLTE or Wifi calling will appear in the settings which I have already done. I have also enabled it of course, but still not working.

You need to have the volte service enabled by phone operator for your sim card. If working for some phones (ex. Samsung) it's like my operator (Digi EU), it's enabled automatically for some IMEI types. If you can, try to keep your sim in a supported phone, or try to ask the operator to enable the volte service.
This way you can make the volte working, for the vowifi... if you are lucky, your Redmi Note 7 have a working vowifi modem config for your operator... I needed to change the modem profile using the Qualcomm PDC tool...** https://forum.xda-developers.com/showpost.php?p=83310915&postcount=26

Enable voLTE on Galaxy Note 4?

Hello,
I am currently with T-Mobile and own a Galaxy Note 4 SM-N910U model, the exynos variant. Is there a way to enable voLTE on this device through some menu? My carrier supports this feature and I know my phone does as well, but it is disabled because the data drops to 3g whenever I make a call.
Anyone?
On mine is in the menu

I confirmed with Samsung that the device indeed has support for voLTE if your carrier supports it. They informed me that it should be turned on by default, which is a lie because my carrier has voLTE and whenever I make a call, the data drops to 3g.

In Japan......if we bring a self acquired device and use it on their network.......certain feature will not work.
Like VOLTE....as I just discovered. They have a separate APN for other devices and it does not support VOLTE.
The other APN that their carrier branded phones use....recognizes the phones based off of their IMEI number.
So.....it might not be a phone issue. Could be your carrier skimming on certain features for phones purchased elsewhere.
Don't see it on my sm-n910f either
hi all, i don't see the menu in my SM-N910F
In your opinion, Is it possible that VOLTE works only on Note4 Exynos? and doesn't works on Snapdragon based Note4 ?

Just go to 'Phone' & then tap on 3 vertical dots and then select 'settings' and then select 'call' and after that enable VOLTE
can someone explain me what is the purpose of Volte? for what you use this?

volte is Voice Over LTE. It is basically what it says on the tin. You can make voice calls over LTE internet connections.
VoLTE (HD voice) and Wifi Calling WORKS with the SM-N910T.
I am currently using this device, with "MetroPCS by T-Mobile". As of 01-29-2021, T-Mobile will only allow the SM-N910T to work on their network. The "T" variant only, because it is T-Mobile's own device. VoLTE (HD voice) will work if you use OEM stock Android 6.0.1.
Here's how I enabled VoLTE (HD voice) and Wifi Calling:
Backed up ALL my files.
Removed SIM and SD cards.
Made sure battery had at least 80% !!
(If using a generic battery, it must be 100%. They drain faster!)
Used Odin (v3.13.1) to flash/install lastest Stock Android 6.0.1. (This wiped everything, even storage, pics, etc.) First boot took over 20 mins!
After reboot, connected to WIFI.
Went to phone's Settings, About Device, Software Updates, and tapped Download Updates Manually. This caused it to find a modem (baseband) update. I chose to install it NOW. It did just that, and rebooted.
Powered off phone.
Reinstalled SIM and SD cards.
Turned phone on, and VoLTE (HD voice) was fixed. Whenever I speak with another HD caller, "HD" appears next to their name.
To enable Wifi Calling, go to Settings, More Networks, Wi-Fi Calling, and enable it.
CAUTION / Extra Info:
A few days ago, I broke the screen on my primary SM-N910T. The screen would not light up, and it did not respond to any touches. I went to a MetroPCS store, to move my account to another SM-N910T. The sales rep said he could not move my account to the other device, showed me his computer screen as "proof", and said it needed to be HD voice compatible. I told him both phones are identical, and both had VoLTE working perfectly. Then he offered to try it anyway for $29 (non-refundable). I politely declined, went home, and swapped the motherboards. All is fine again. I shared this story in case you encounter similar resistance, and need to tell the sales rep you are willing to take a (non-refundable) chance. And to warn you that T-Mobile might have made some changes, that I am not aware of. However, I am currently using the SM-N910T.

[GUIDE] Enable VoLTE on Root (Stock Oos) Devices (only if your provider supports it)

Hey Guys
i found the solution to enable VoLTE on your rooted devices
1. You have Root
2. You need a Root explorer
3. Go in /system/build.prob
4. Go and search this: (Note: Default values are all-->0
change all to--> 1
#ifdef VENDOR_EDIT
persist.dbg.ims_volte_enable=1
persist.dbg.volte_avail_ovr=1
persist.dbg.vt_avail_ovr=1
persist.data.iwlan.enable=true
persist.dbg.wfc_avail_ovr=1
#endif
5. Save it and reboot
6.After reboot enable it in Settings --SIM & network
7. A Big Note: Your Carrier provider must support it......if not.......you have enabled it and nothing happens
------>You can test it if it works,by doing a call....when 4G still shows by your call,then your provider supports it
If 4G disappears.....hmmmm then not
cheers
try it out
Would be great if you could find something how to enable VoWifi for UK EE network. Or let me know where to search. VoLte works fine but Wifi calling not showing up.

EE does support WifiCalling but Oneplus need to bake it in to rom. Only VoLTE works.
Thanks a lot mate. Worked for me.
Should this just work if the carrier provider supports it or does the carrier need to support this specific phone as well?
I think I'm on the same carrier as danmaman (Vodafone in Germany). They support VoLTE in general but primarily for Samsung phones. OnePlus devices are not on their list. If I remember correctly it's the same with Wifi Calling.
I tried to activate VoLTE this way but it didn't work for me although it's available in my contract. Wifi Calling doesn't work either.

VoLTE is working on Mate9 finally (kind of)!

My phone is MHA-AL00C00 and I want to use VoLTE in Rogers network. But the menu of volte is missing and I heard some body using C636 and enabling Volte in US T-Mobile networking. So I re-brand my phone to C636B191. But still there is no VOLTE menu available. Then I used QuickShortcutMaker to enable WIFI calling setting anyway. Then I upgraded to Andorid O(MHA-L29 8.0.0.0.360(C636)) and I found Volte menu is available and it is enabled. But the real phone call is still back to 3G and there is no VOLTE icon in status bar. So I used another SIM card with VoLTE enabled in Iphone 6+ and I found there IS VOLTE ICON in status bar. Please see the attached screenshot and I placed a call and it didn't switch to 3G so it is real VOLTE call. But unfortunately this icon is gone after a while. I guess the Mate 9 phone is not VOLTE certified device in Rogers network.

From Rogers forum somebody mentioned to contact level 2 support to add your IMEI to Rogers database then you should be good to use volte.

Just chat with Rogers and this function is not enabled on my account. After enabled you have to update your emergency address and submit to Rogers. I have done this on a Rogers iPhone 6. Now I have volte icon always.

Yes. no fall back to 3G when calling. But it only lasts 2 hours and this VoLTE is gone again. Re-chat with Rogers agent and they said it is not working on non-Rogers phone even you are lucky to get working for a while.
Sad!
Update:
This morning I just found the VoLTE icon is shown on status bar. After place a call the call log shows it is a VoLTE call (It also indicates it is VoLTE call during the call)
It looks like Rogers remove VoLTE restrictions on non-Rogers phone.
If the IMEI on your account is VoLTE capable, then VolTE will work for non branded devices, as long as the imei doesn't change.

VOLTE Wifi Calling with Unlocked S10+

Hey there, I've been doing a bit of research but it has been a long while since i have done any flashing of firmware etc. I received my s10+ device today. Model number is SM-G975UZKAXAA. I am a Verizon wireless customer. When I placed this device on my account I noticed I have no access to Voice over LTE, and I also do not have any access to Wifi Calling. My question is the following. I read somewhere a couple of weeks ago that if I wanted something like this I would need to flash the original VZW Firmware which would have all the lovely bloatware etc on the device. Is there any way I can do that? I have seen firmware that has been posted but I dont seem to see anything that specifically is the VZW apps etc which should (hopefully allow VOLTE and Wifi Calling and maybe even HD Calling, if thats a thing)
I would appreciate any info anyone can provide me on this, as the only solution I can see at the moment is to return the device and start over with a VZW specific device.
Cheers~
Likewise but with a T-Mobile firmware for me

Hey guys, just wanted to check in with you (or anyone else who has wifi calling on unlocked Verizon). It is 100% working? It's the only reason I got the carrier version. Should I cancel and order the unlocked?

I don't think that is right. LTE+ and VoLTE are different things. As well as data while on a call.
VoLTE means your call is being transmitted over LTE. I'm pretty sure you can use data while on a call WITHOUT VoLTE.

How do you test if VoLTE is working? Do you get an Icon for it?
I tested WiFi calling by going into airplane mode, turning Wifi on, and making a call and it worked. But didn't get a special icon for it.
For those basing your decision to buy unlocked/international vs branded, be warned. I can only speak for Att, but I spent about 2 hours arguing with their level 2 tech department and here's what I have learned. If you have a sim that is provisioned on a branded phone and then put the sim into an unlocked/international phone, you will be able to use volte, wi-fi calling, etc., but only until the carrier pings your imei for a periodical check, once that happens, those features disappear. Also, on Android Pie, the Enhanced LTE Services tab under Mobile Data has been removed as it is turned on by default, also confirmed with ATT. The only way to manually check is to toggle wifi calling on and see if it works. Anyway, just trying to help as I have gone to a branded phone for the first time in 6 years because the reception and enhanced features are more important than rooting to me.
I was able to get wifi and volte working on my unlocked s10 by putting sim into verizon phone, letting network recognize it, enabling advanced calling and such on that device and then taking the sim out and putting it back in my new unlocked s10. The option for volte appears in settings-connections-mobile networks.
VoLTE works on tmobile, not that anyone should be surprised. That has been the case for the S8 thru N9. Now... I noticed that Samsung removed the VoLTE toggle from settings.

Using what I learned in this thread, I called Verizon and talked to Level2 support. They tried to get everything working and could not - but this was when I had the new SIM installed, provided by Samsung when I got my S10+.
So because others here spoke of their 'other' SIM, I suggested we try that - so I plugged in the SIM from my S8 and asked them to reprovision everything. They did... and....Now everything that didn't work ... WORKS.
So I have an Unlocked S10+ on Verizon that has (among other things):
- Wifi Calling
- Real Time Text
- VoLTE ("HD Voice") (Which means data now works while I'm on a phone call)
- Visual Voicemail
So it seems the Samsung SIM was part of the problem, and they are reporting this to Samsung. The tech support person told me others have reported similar issues and they will get with Samsung to figure out what the issue is.
Hopefully this helps some others as well!

VoLTE or WiFi calling working on Redmi Note 7?

Using Redmi Note 7 Global version, 4G+64G, MIUI 10.3.2.0.
VoLTE
I entered *#*#86583#*#* and dialler confirms that VoLTE carrier check is disabled (test page 4636 also shows VoLTE provisioning is ON).
On different phones using same SIM, same location, I see "HD" icon confirming "HD calling", or "VoLTE" but NOT on my Note 7.
And no new android menu items about VoLTE have appeared.
So, at first glance it seems that VoLTE is not working.
HOWEVER If I make a call, the display continues to show "4G+" and data keeps streaming, so VoLTE must be working, right? or maybe not?
WiFi Calling
I entered *#*#869434#*#* and test page now confirms that WiFi calling provisioning is ON.
And yes, a new menu item appears SIM card settings, "Make calls via WiFi". (OK so far)
However when I enable WiFi and disable mobile signal with flight mode, I cannot make a call. Dialler tells me "mobile network isn't available. Connect to a wireless network to make a call".
Also if I go to an area with no mobile coverage (instead of flight mode), same error.
I believe that my carrier (Three UK) is supposed to support VoWiFi.
So is WiFi calling broken in MIUI 10.3.2.0 ?
There should be a VoLTE icon when you open the notification shade. Works well for me, even though I have the MIUI 10.3.2 EU ROM, and I had to enter the *# code in order to get it working and for the toggles to appear under SIM settings

Thanks for the reply. Hmm yes, that's what I expected, but icon is definitely not there.
It's especially strange since I have definitely had VoLTE with the same SIM successfully on different devices.
What do you make of my phone staying on 4G during a call, does that suggest VoLTE is actually working?
If your 4G icon doesn't change into 3G (H) while in a call, I'd say VoLTE is working for you. It might be that there is something missing in the VoLTE handshake between the carrier and the phone, not passing all the checks and resulting in the phone not detecting "full VoLTE connectivity" and not showing the icon. If a call to another phone also using VoLTE starts ringing really quickly, if the sound quality is really good and your phone shows that it's connected to a 4G network, that should be it. HD or VoLTE icon or not, the functionality is there.
You said the same SIM has had VoLTE on other phones, so the carrier side should be OK. Although I suppose there might be a device whitelist on the carrier side – there sure was one when VoLTE was first introduced, as not all VoLTE-enabled devices were eligible for the service. At least that's how it was in my neck of the woods. So if all else fails, you might want to verify that with your carrier.
On the Redmi Note 7 though, as I said, it required that I enter the *# code for VoLTE. After that, the VoLTE toggle appeared under SIM and wireless settings. I can't tell if the toggle was in the "off" position when it appeared, but I'm quite sure that right after seeing or switching the toggle, I checked the status bar for a new icon, and there it was. No restart was required. You could try re-entering the code and seeing if the toggle appears (as in the screenshot).
Your profile states that you're in a brexiting location, which makes me think – do you have the Global ROM or the EU ROM? My MIUI version says PFGEUXM and VoLTE has been known to be disabled or not working in certain editions of MIUI.
I enabled VoLTE toggle and also Calling over Wi-fi but when I try to make a call it won't work saying I need to establish a cellular network connection.
Is there a way to make it work?

Your mobile carrier needs to have VoLTE enabled on your account to make it fully work
use *#*#86583#*#* as ON/OFF switch !
===================================
use it once = it turn VoLTE "ON"
use it second time = make VoLTE "OFF".
For "Use Wi-Fi to make and receive calls" type *#*#869434#*#* once.
for turning "OFF" use the same code (*#*#869434#*#*) second time.
Easy-peasy !
(btw. I'm on MIUI Global 10.3.6, no root, original ROM)
@kljoki
I have it exactly like this. Because when it is deactivated you can't see toggle options in settings.
I am on MIUI Global 10.3.10 Stable PFGMIXM
So what am I doing wrong.
My provider O2 Telefonica is supporting Volte?

Sorry I'm on Xiaomi Note 7 .
( I think there is no help from my side.)
Has anyone got WiFi Calling to actually work?
If so which carrier are you using?
Have the feature activated but like the other poster, I cannot make calls over WiFi (T-Mobile) made wonder if there's any additional steps needed to activate the service
Could someone already test if VoWIFI is working with the Miui11 Beta versions, plz?

Did you already get any answer or news about it ?
Derpfast-Rom is unfortunately not updated any more - had VoWifi working...
Have a feeling they disabled it on purpose to not canabalize their higher end model sales.
It's been the same story since MIUI 10.3.5

I'm using latest crdroid with no success on this subject. BUT i use TIM Brazil carrier so i believe this is not a rom related issue, but a device+carrier issue.
VoLTE has worked great for me from the start. Had to enter the VoLTE code in the dialer to get the switch in the options to appear though.
VoWIFI - what's your motivation to use that? I have good coverage where I live and I'd rather have a real cell phone call than for it to go through my home or office wifi without QoS set up to prioritize voice calls.
is it right that vowifi doesnt work with miui 11.0.5 on my redmi note 7? VoLTE works?

Unfortunately I'm just having wifi during work inside my hospital.
Means I'm not getting any calls on my mobile as a backup. Quite disappointing. :/
Update:
By a HowTo in the german android-Forum I made it possible to activate VoWifi on my Redmi Note 7 , without rooting or bootloader unlocking.
Had to delete row_commercial profile and activated Commercial MTS for Telefonica in Germany.
Works perfectly -. @Antaril

Wow so you got it working?
Can you share the link to the German thread here?
I'm curious how they determined Row Commericial must be deleted.
That's what my phone defaulted to and showed as active under the Sub0 column when I connected it to PDC
