VoLTE not supported? - Samsung Galaxy Note 9 Questions & Answers

Hi,
I have been trying to get VoLTE working on my
SM-N9600 (bootloader unlocked Snapdragon version)
but I cannot seem to get past this error "Volte is not supported by this software version please contract customer services" I have manually changed out the CSC to my home country but I noticed in the CSC verifier it says unsupported items and list all the VOLTE items has anyone else experienced this?
Yes I am rooted already if required

You need to check if your Cell Provider provides support for VoLTE. As some Cell Networks do not offer that service. If they do, get them to check that it is activated on your SIM.

Got 2 sim cards from different providers
Telecom NZ (Spark NZ) the rep said they have manually activated it on my account
Vodafone NZ Launched and testing SIM in working device

N920I enabling VOLTE. [Rooted]

Hi,
I have a Singapore N920I. Im using the phone in INDIA and am not enable to Enable VOLTE. its says 'unsupported by current software version'. Ive tried enabling the 'turn off volte provisioned flag' but doesn't work when tapping on it. My device is rooted. Is there any way to enable VOLTE on my phone.
Android version : 6.0.1
BaseBand: N920IDVU2BPE2
Model : SM-N920I
Thanks
As far as I know, and don't quote me on this. You cannot. The volte service is different from carrier to carrier. For example, I had a Verizon s6 when I switched to T-Mobile. Both networks support volte/advanced calling, however when I tried to activate volte on T-Mobile, it didn't work. The software is looking for the wrong signal. You're best bet is to sell the one you have an buy one compatible with your carrier. Also you could check over on the general note 5 development threads. There is far more support over there for devices that aren't the 920t. Hope this helps.
Your CSC doesn't support the other network. So its like trying to log into a website with a different website account.

WiFi Calling (EE UK) -> Phone Purchased Indirectly.

Hello Friends,
Having Googled Up & Down accross the Interwebs, I am frankly Stumped.
The UK Mobile Network EE offers the P8 Lite (2017 Model) (PRA-LX1) with Wifi calling directly.
Until recently they had web posts saying this phone is WiFi Calling compatible whether purchased from EE or indirectly.
However this is not the case. My Version was purchased unlocked, from Carphone Warehouse UK.
I have force updated the firmware to PRA-LX1C432B191.
I cannot get the Wifi Calling option to Display (Or VOLTE)
However B191 firmware is supposed to support VOLTE & WiFi Calling.
Suspect either some custom apps or configurations exist on the EE provided phone that is not on My handset.
I am Happy to root, Mod, Unlock and try to enable this option.
Where do I start looking? Could you tell me where I can find the right firmware,
or mods, hacks or changes to enable this feature?
Why would the EE shipped phone have wifi calling but the unbranded unlocked version not?
It is the very highly strange situation.
Cheers friends, looking forward to your insights and suggestions.
WiFi calling may need to be enabled on your account by EE tech support, this used to be the case a few years back when I was a tech support agent for them.
Confirmed, wificalling is enabled on my account,
They also did a network refresh on my account.
Still cant see the option.
*bump* anyone can help me enable wifi calling feature on this device?
the rom should support it
I'm in a similar situation, although I am still stock at LX1C432B115. Can I ask how you force updated to 191?
I had a look at an EE handset and that had the build PRA-LX1C440B163 and the wifi calling menu items were visible. I had wondered whether flashing that (or the latest ee build C44?) onto the phone was possible\the easiest way to get it working.

Unlock Carrier IMS settings.

Hi all,
Im looking for some help with my Note 8 which I bought outright from Vodaphone "Unlocked".
Due to coverage issues I have had to switch to telstra (Telstra sim) which seemed to work ok with no issues. Untill I realised that VoLTE was not enabled nor is their an option to enable/ disable this setting.
I have tried a Vodafone sim and the VoLTE option is displayed and I'm able to toggle it on or off, However reinstalling my Telstra sim doesn't give me the same option.
I have spoken to Vodaphone who advised my the phone is unlocked and in some sense of the word it is (No branding whatsoever) Though according to some sources online its because the phone is part of Vodaphones database which specify the IMS Carrier settings.
I have attempted to flash the phone with an "official telstra" Rom sourced from sam mobile and it made no differance. How can I wipe these annoying IMS carrier settings so i can use VoLTE and video chat with any carrier no just Vodafone.
Any help, tips or tricks will be greatly appreciated.
Cheers,
Natz.
When I bought my N8, directly from my carrier, it was branded, but unlocked, no Volte option anywhere, 1 week later I received a message from my carrier telling me that the Volte calls were available, And instructed me to take my device to them for activation,, I did it, providing proof of purchase, they only checked the IMEI, then they made the pertinent changes in their system, nothing to the phone, and issued me a new sim card, after putting the sim, The Volte option appeared, you may need to go to Telstra, anyway that was my experience

VoLTE and Wifi Calling support

Would like to know if these features are supported for the major US carriers. That's the only thing holding me back from pre-ordering.

I know U.S. T-Mobile supported the XZ3 for VoLTE, which was the FIRST Sony unlocked phone it did that for. Your best bet to find out is prob to go check out other like 2019 or 2020 unlocked phones that people have VERIFIED to offer both on AT&T as well. But if that's an issue, then you may wanna consider T-Mobile then. I noticed on the XZ3 that in Call Settings there no longer was the option to turn VoLTE on or off, but during calls it REMAINED in 4G LTE (vs. just 4G), thereby proving VoLTE was in fact enabled.
The US Xperia 1 supported voLTE on T-Mobile, but not WiFi calling. So I'm assuming the mark II would at least do voLTE on T-Mobile. Not sure about the other carriers, but I feel like it would have to since carriers like Verizon are starting to not allowing non voLTE devices to be activated. And the mark II is supposed to work on Verizon.

How is this a solution? Switching carriers lol
I want to preorder, but really need WiFi calling. Going to wait until regular users start to receive theirs. Right now with Xfinity Mobile we are paying about $30 per month for 5 lines. The service is as good as when we were Verizon postpaid. Not willing to switch just for this phone.

Yup, got both (see attached)
I have none of those settings there.
I also don't get 4g+ don't know if that's related?
I get 4g+ if I put the missus Vodafone sim in.

I should have mentioned also that I'm actually on the "Customized UK" firmware opposed to the "O2 UK Pay Monthly firmware" but I had WiFi calling for sure prior to this
So my Xperia 1 ii arrived today, I'm finishing-up set-up. This is the US model, which I'm using with ATT. The deep dive *#*#7378423#*#* on the software info page states: "Current modem config: VoLTE-ATT "
But have yet to find any configuration for VoLTE or Wi-Fi calling. I'll try a call with one of the other lines in my family, who have ATT branded newish phones, to see if it "sounds" like an HD Voice call (there's not notification bar indicator of HD call, right?).
Update: Tried the other *#*#4636#*#* and the options under Phone Info are all grayed out (sigh)

You have to call ATT to whitelist your new IMEI for VoLTE provisioning. Then you need to make sure a new sim that supports VoLTE. This is what they told me but I'm missing the new sim, going to get one tomorrow
Thank you.,I'll give that a try. My SIM is the supposedly latest, about 2 years old, i. e. "A compatible SIM or eSIM card will display 25, 26, 27, or 28 in the ninth and tenth digits spots." Is there a newer SIM for ATT?
So had the following chat with ATT tech support:
"... Calista : To confirm, was the device purchased through AT&T?
Me : No, this is an unlocked phone, US model of Sony Xperia 1 ii
Calista : Thanks for the confirmation.
Calista : I have successfully activated VoLTE on the new device.
Calista : I have also checked and see that Wi-FIi calling can only be provisioned only on the device that are purchased through AT&T. However, AT&T will soon activate WiFi calling on the device that are not purchased through AT&T as well. You will be notified about this. "
However after power-cycling my phone and reprovisioning via Testing/Phone Information and on that page the steps of Refresh to get the SMSC number then tap Trigger Carrier Provisioning"--nothing, not VoLTE live switch. Remains gray. Still, interesting comment by tech support about upcoming Wi-Fi calling on BYOE.
Anyone know about VoLTE on Verizon yet? Just ordered my phone today and hoping that it will work.

Those tech support chats are useless! Took me 4 calls/chat to get to one knowledgeable one who said they have to file a level 3 tech support ticket and as she was doing it she said our internal memo said this cannot be done for non-AT&T branded phones so I'm sorry
Why not just use Google Voice for wifi calling? I use Google Voice for just about everything now as it's a nice alternative to giving up my number to random businesses.
Is it possible, to install the VoLTE/VoWifi carrier settings by an app (as .apk)?
My problem is that Sony didn't include these settings for Swiss carriers. So I am thinking about, how to add these settings without breaking the firmware.

VoLTE is required to continue to use AT&T after they sunset 3G and 4G (without VoLTE). Speaking of Google, they've confirmed to me that this phone (US version) works fine on their Google Fi, supporting VoLTE, which is interesting in that Google Fi is an MVNO via Sprint, T-Mobile, and U.S. Cellular.
So if I give ATT an IMEI for a Nokia Lumia 830 or Microsoft Lumia 640XL (both on AT&T's "good" list) to associate with my SIM in my Xperia, will my Xperia be provisioned by AT&T with VoLTE & Wi-Fi calling?

Question VoLTE

Has anyone figured out how to force VoLTE on Origin OS Ocean when the phone isn't on the 'supported' list of your carrier? If it is supported then as soon as you pop in their SIM card the option to enable VoLTE appears, but otherwise it just isn't there. With 3g networks shutting down in North America this creates a real problem, because even though I have 5g enabled, and usually pick up a 4g or 5g signal where I live, without VoLTE enabled all calls connect on 3g.
It's a real bummer. But whatever is under the settings, VoLTE is not actually activated. And Vivo is to blame. That's obvious from the service menu.

In Italy after 2/3 days Volte is automatically activated (operator Vodafone). Didn't touch any settings.

The VoLTE issue lies with Vivo, not with your carrier. When you put a carrier SIM into your phone it contains unique information that tells the phone who your carrier is and the phone then configures the APN settings automatically. You cannot edit them. In Origin OS Ocean you can open System/etc/apn-config.xml and you will see a list of every carrier in the world and read what default APN settings the operating system automatically configures the APN for that carrier to be.
I have the Vivo X Note with the same Origin OS Ocean firmware as the X70pro. My Canadian carrier supports VoLTE and WiFi calling and their tech support manually added the IMEI of my phone to the equipment list for my line and assured me that VoLTE and WiFi calling are provisioned for the line, but neither of those toggles appear in my Mobile Networks/Sim settings, because the APN that Vivo applies for my carrier doesn't support VoLTE. If I put the same SIM into my Samsung Note 20 Ultra 5g or my Huawei Mate 20 X and look at the APN settings, they permit VoLTE and the toggle and feature works on those phones - so it is not the carrier, or the SIM - it is Vivo and their default APN settings for your carrier.
I have a strong 5g signal here, and I can download and stream or do VoIP calls at 5g, but when I place a voice call it drops to 3g or H. That isn't an issue here in Canada, because we have kept our 3g voice network up and running. When I travel to the US, however, I can't place calls because without VoLTE enabled voice calls drop to 3g - which no longer exists in the United States. Someone needs to convince Vivo to change the apn-config.xml file to reflect APNs for North American carriers to ensure VoLTE is possible. I would just edit the .xml file myself, but you can't save changes to an .xml file without root, and we can't root because Vivo won't unlock the bootloader for Origin OS Ocean devices.

I don't think it's a Vivo problem. Carriers should give you access. As said before after 2 days I have Volte and HD icon even if device is not ufficial supported. I didn't change or touch anything. If your carrier uses a restricted policy on 5G or Volte there is nothing you can do.

My experience with VoLTE is kinda weird, settings show me that I have both VoLTE and VoWiFi enabled. But none of them really work. It's true that obviously system recognize that, send me a notice that I could have VoLTE enabled and routes me to the message to my provider. And even more thrilled - I can toggle VoLTE in settings, get the HD voice sign in notification bar, but I don't have any VoLTE. The only direct consequence of the toggle is that I lose the caller's name in the phone, every caller becomes the unknown number. But my provider is not trustworthy, the other users have issues with VoLTE, I frankly don't know anyone who has it enabled. Thus, I tried my wife's sim and didn't get even option to enable VoLTE. My wife has a Chinese (Honor) phone and both VoLTE and VoWiFi work with this phone flawlessly. That's why I assume that the problem is on Vivo's side.
