First I do not have an S6 yet but am researching before Purchase and main concern
is Battery Life ....but this is a General Question.
On Metro PCS/ Tmobile we already have VoLTE on all Devices which have 4G LTE
Radios which are Carrier Branded Devices.
Metro PCS was one of the first so back in 2012 my little LG Motion 4G had simultaneous
Voice and Data on LTE Band .
My current Factory Unlocked Alpha 850M is CAPABLE of VoLTE but lacks the specific
TMobile Software for VoLTE on this Network so as soon I make a call the LTE
drops down to 3G or H H+ to make the call then returns to LTE after the call.
All unlocked Devices do this .
HOWEVER: the Galaxy S6 has a VoLTE setting in the Menu - on a MetroPCS/Tmobile
version on Tmobile/Metro you already have this function so:
1) What does VoLTE switch do on S6 Tmobile version - you stay on LTE During calls
either way - right ? VoLTE ON or OFF.
2) Since there IS a VoLTE switch will this be the FIRST Device that enables VoLTE even
as a Factory Unlocked version running on Tmobile/ Metro ?
Meaning - is this the beginning of VoLTE as a Universal Android Feature across many
Carriers not requiring specific Carrier Software for a Specific Network to enable
VoLTE on multiple Carriers ?
Thanks for your patience - I am not a Dev and have learned much here.

I don't believe this is the case YET. Android AOSP has VoLTE built into it as of OS version 5.1 (as seen with the Nexus 6). Prior to this the VoLTE was handled by carrier software on carrier devices. I do not know if another carriers S6 will use VoLTE on T-Mobile without being flashed with T-Mobile software first.
That being said going forward we should see a VoLTE "Universal Android Feature" that is compatible with any device/enabled carrier but not until 5.1+
You're confusing a few different things
- Simultaneous voice + data was always available on GSM networks, it uses the regular GSM radio to place the call and then data is separate. This is not VoLTE.
- CDMA carriers (Verizon, Sprint, old Metro PCS) had trouble with voice + data, CDMA didn't allow it to work. When LTE was introduced, it gave them the ability to connect voice through CDMA and data via LTE, so that's how they were able to do simultaneous voice + data. This is also not VoLTE.
- VoLTE is sending the call over the data LTE network. This is also different to WiFi calling. So instead of your phone call being transmitted as a voice call, it's turned into data, and sent through T-Mobile (or whatever carrier's network) as data. You can have a VoLTE call and use data as well, it's the equivalent of having 2 data apps running at the same time.
- There have been a few VoLTE enabled phones already, I believe the Note 4 and Z3 both have VoLTE. There are probably others, I just don't know off the top of my head.
We have Had VoLTE Phones on Metro PCS since August 2012
Again-we have had VoLTE Phones since 2012 on Metro PCS :
http://www.pcmag.com/article2/0,2817,2408750,00.asp
I had one of the first Models called LG Motion 4G- the Call
AND the Internet while on the Call were all over LTE.
Metro PCS was one of the first to offer this and most of their
LTE ( if not ALL) have had this feature since AND TMobile has
adopted this Feature to most of their phones.
But I don't want to get bogged down in that Question.
The Question is - On Metro PCS /Tmobile you ONLY Get VoLTE on a Metro branded Phone-
AT&T issued an OTA UPDATE for their first VoLTE Phone which
was Galaxy S4 Mini .
There is No Factory Unlocked Phone which can get VoLTE on Metro PCS ( but their Branded 4G LTE phones do have VoLTE)
BUT - since VoLTE is a Function in the Galaxy S6 and is somewhat supported by Android Lollipop -
Will Factory Unlocked Galaxy S6 be the First Phone which will
Stay on 4G LTE during a call even when you get on the Internet?
Other Phones which are NOT Carrier Branded drop down to 3G during calls and thus have slower data speeds during calls etc.
The new Galaxy S6 Active will probably have an SD Card and much larger Battery -probably exclusive to AT&T
BUT Factory Unlocked Models will become available -
1)IF I get a Factory Unlocked S6 Active and turn on VoLTE Feature-will the Device stay on 4G LTE during calls with Data - VoLTE ?
2) Metro PCS LTE phones and Tmobile LTE Phones already have VoLTE so again what is the difference on S6 if you turn VoLTE on or off in the Menu ?
3) My Factory Unlocked Galaxy Alpha 850M does not have the VoLTE software for Metro/ Tmobile so I am on LTE but as soon as I make a call I drop to 3G ( it shows on the screen) with slower data and sometimes data interruption.
Will S6 do the same thing if an Unlocked Phone or be the first Factory Unlocked Phone with VoLTE across multiple Carriers ?

I have a MetroPCS Galaxy S6 Unlocked and VoLTE Works Fine and also I have the T-mobile firmware on it I'm not sure if that would change anything but I was just saying for me it works perfect

Hello guys,
So I've imported a Vivo X Fold from HK and I was wondering how do I enable the 5G bands? I've seen this thread for Samsung, is there perhaps a similar method or something else to do for Vivo?
(Of course, I checked, my carrier is using bands supported by the Vivo X Fold)
Thanks!
I've just imported the Vivo X Note from HK and it has the identical Origin OS Ocean firmware and the same radio hardware and frequency bands as the Vivo X Fold. I just plugged in the Sim Card I had been using in my Samsung Galaxy Note 20 Ultra, and voila, I had 5G service. I had the same question as you, because sitting in my study at home my phone displayed 4G+ at the top, but the other day I put it in the car cradle and as I drove down the street it switched to 5G. I then realized that my house is not within transmitting distance of the local 5G tower, but many other areas of the city I live in are. As a brand new technology 5G coverage is not as broad as 4G.

Not sure if this helps you but I ordered mine from China. I live in the Netherlands and 5G worked "out of the box".
There is actually a setting on the phone that is off by default. Settings/Mobile Networks/Sim has a toggle for 5G. I toggled it on and had a 5G connection (Canada) right away. The options that appear in that Sim submenu, however, are activated by inserting your carrier's Sim card. If your carrier supports the Vivo X Note or Vivo X Fold for 5G, VoLTE, and WiFi Calling, you will see three toggles there - one for each. In my case I only have the toggle for 5G, no VoLTE or WiFi Calling settings because my carrier will only provision those services for phones that it sells. If you go to that submenu and don't see the toggle to turn 5G on, then you may need to get a new Sim card from your carrier. Some carriers require the use of a new 5G Sim card, others allow 5G with an ordinary LTE Sim card.
I am using the X Fold on T-Mobile USA, while the 5G icon is showing when I go into System management≥ Status Info≥ SIM 1 Status it's only displaying my phone as connected to LTE and shows as having no signal for NR. From running speed test I can confirm I'm getting the same speeds as my Xiaomi Mi 11 Ultra which only runs on LTE. I have T-Mobiles 5G home internet where I get 400+ download speeds so 5g coverage isn't an issue in my area.
T-Mobile's "5G Home Internet" uses a Wi-Fi Gateway (combination modem and router) that connects to T-Mobile nationwide XR (extended range) 5G towers which broadcast on 5G frequency n71. The Vivo X Fold can't connect to these towers. It can connect on 5G frequencies n1, n2, n3, n5, n7, n8, n12, n20, n28, n38, n40, n41, n66, n77, n78, and n79, but not n71. T-Mobile has put up a few Ultra Capacity (UC) 5G towers in big cities and if you are range of one of these your Vivo X Fold will connect on 5G n41 and display "5G UC" when it connects. These new towers also broadcast on 5G n258, n260, and n261, but the Vivo X Fold won't connect on those frequencies. So long story short - your T-Mobile Wi-Fi Gateway will connect to 5G n71, but your Vivo X Fold won't, and unless you are within range of one of the new 5G UC towers your calls will connect on 4G.
I am aware, I am in NYC my TMo gateway is connected to N41. The tower is across the street from me. Here what I see on my phone.

Odd that your phone is displaying the 5G symbol (as well as VoLTE 'HD') when your Sim Status signal strength shows 0 for NR (5G), but is showing a strong 4G signal. I wonder what triggers the 5G symbol when you clearly aren't receiving a 5G signal. Have you used a signal diagnosis app like OpenSignal to see what is broadcasting in your neighborhood?

Everything except mmWave. If you have the phone and T-Mobile service are you running into the same issues?
I'm leaning towards following this tutorial as this is a Chinese phone and 5G might not be configured to work in the US.
Modify OnePlus 7 Pro 5G, 8 and 8 Pro, 9 and 9 Pro NR/LTE-A band combos - MT-TECH.FI
On this instruction we will modify OnePlus 7 Pro 5G, 8 and 8 Pro band combo profiles with Qualcomm software. OnePlus has limited 5G access and 4G+/LTE+ Carrier Aggregation combinations and this instruction help you to unlock. However this instruction doesn’t unlock hardware defined combinations...

I think you have hit the nail on the head. Countries and telecom carriers had the choice of deploying 5G NSA (not stand alone) or 5G SA (stand alone) technology. 5G NSA provides a 5G signal that piggyback's on a 4G signal and actually relies on an already established 4G infrastructure (towers, servers, switches, etc.). For a 5G phone to work on a 5G NSA network, the phone must have both the radio bands for the 5G frequency, and for the underlying 4G frequency that is necessary for the 5G NSA to work. Most American carriers opted for mmwav 5G NSA technology. On T-Mobile, therefore, your Vivo X Note or Vivo X Fold are 5G SA and 5G NSA compatible, but because T-Mobile uses 5G NSA the phone must not only be capable of connecting on T-Mobile's 5G frequency, but also on the 4G frequency that its 5G frequency piggybacks off. That 4G frequency for T-Mobile is LTE 71, which the Vivo X series doesn't have. I'm in Nova Scotia where my carrier (Rogers) built a 5G SA (stand alone) network, so as long as I can connect on one of its three 5G frequencies (I can connect on two) then I don't have to worry about the phone also connecting on an underlying 4G frequency. But unlike T-Mobile, my carrier won't provision VoLTE for my Vivo X Note, so all my voice calls drop to 3G. If T-Mobile followed my carriers policy you wouldn't be able to place any phone calls because you have shut down your 3G towers. So I have 5G for data (downloads, streaming, etc.) but 3G for voice calls, and you have 4G for data and voice, but no 5G.

Are you able to manually turn VoLTE on with the code *#*#86583#*#*? There is also an option to turn on VoNR in developer settings.

Thank you for sharing this. I used the dialer code and it gave me the option to enable VoNR (although it didn't give an option for VoLTE). I enabled VoNR but while my phone shows I'm receiving 5G, when I place a voice call it still drops to 3G or H. I phoned my carrier, and they told me they have added the IMEI of my Vivo X Note to the line and have provisioned VoLTE, but I don't believe them. When I called them the other day they told me if I wanted VoLTE I would have to purchase the device from them. After enabling VoNR with the dialer code I can go into developer settings and there I see that it is toggled on, but the Settings/Mobile Networks/Sim 1 submenu still just shows the toggles for "enable 5G" and "enable data roaming", both of which are turned on. I just don't have the "enable VoLTE" option there. If I was rooted I would force the option to appear by editing my build prop, but I don't think anyone has figured out how to root the X Note or X Fold yet. Someone is working on root for the X70pro and they have successfully flashed FunTouch on the CN Origin OS Ocean model, but trying their experimental method on my new Vivo X Note is a bit to adventuresome for me.
I'm sure you've probably tried this already, is VoLTE greyed out in the *#*#4636#*#* service menu?

I just had an interesting argument with a service tech for my carrier just now. Each time I call I get a different tech and a different answer, but his guy gave me the stock "if you didn't buy the phone from us those features won't work" line. I told him I know people who have non carrier purchased phones and VoLTE and WiFi Calling works on their phones. He said: "that's because they are using a model we sell ourselves". Knowing that none of the Canadian carriers sell Huawei devices I aske him if that would apply to a non-carrier Huawei purchased in Hong Kong. He said "of course that wouldn't work". I then asked him to look up the account for my wife's line, which he did. I asked him what information his screen was telling him about her line. He said "I see her IMEI was registered on May 17th". I told him that was correct because on that date I swapped SIM cards between our phones and when I put her SIM back into her phone it would have registered again on their network. He went on to say: "it says in bold letters here 'non-carrier device' and VoLTE enabled NO, WiFi enabled NO.". Her phone is a Huawei Mate 20 X which I bought at Trinity Mobile in Hong Kong three years ago. VoLTE and WiFi Calling both work great on her phone. I can toggle off VoLTE on her phone and her 4G signal drops to 3G when placing a voice call, or I can toggle VoLTE on and place a voice call and it stays on 4G and displays the HD Call symbol as well. Weird science!
I tried to check if volte is greyed out but *#*#4646#*#* doesnt work with the phone. how can i go to that menu?
I have tmobile and live in illinois and my 5g and volte is working. Can confirm if you need pictures.

Same but i had to force root to get VoLTE working
Maybe it is Operator dependent as here in the UK (on Three.UK) I have 5G everywhere where other phones have it and also I have HD Calls icon and VoLTE enabled (have not done anything specific for those to work). Pretty soon Three.UK will be shutting down their entire 3G network so there will be only 4G and 5G...
Hi Guys, Just sharing my experience with you . I'm in Australia with Vodaphone. % g works as well as volte, haven't done anything special. I've travelled to the US this week, and 4g is ok, as well as 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.

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.
