Question About S6 VoLTE( redundancy ?)On Tmobile - T-Mobile Samsung Galaxy S6

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

Will nexus 6 support data while on a call?

Apparently the droid turbo can't, which is amazing as far as I'm concerned, and unfortunately a deal breaker for me.
Someone please tell me this phone won't have the same problem?

This will be fixed soon on all the new Verizon phones. Same with the Sony Z3v.
It depends on the network. ATT can data and call.
Verizon phones can. I have a note 4 and can make calls while browsing the web
---------- Post added at 01:58 PM ---------- Previous post was at 01:57 PM ----------
I'm not sure about all Verizon phones I guess. I just mean it's possible on their network right now
At first most likely not. Droid life did a video making a call while on Verizon and it dropped data as soon as it started calling and came back once finished.

Wow hopefully that is fixed with the upcoming update being pushed before release.

Its not something that is broke ....the oem are making these phones with only one path from modem .... either data or phone can use but not both. ..it's been that way since g2 on sprint ...you can use wifi and phone though
You can when vzw goes VoLTE since it will be using the same network type. This uses same antenna as I phone and other moto devices that do not support simultaneous voice and data
Does Sprint's Spark network support it?
I think Verizon has given the date for the update as mid December. At least for the Turbo, that's the case. Still somewhat mystifying why you would release three major "flagship" phones— Sony zv3, Droid Turbo and the Nexus 6— before your ducks are in a row with simultaneous calls and data.

VoLTE
I'm confused. I thought the fact that voice was over CDMA is the reason why we can have simultaneous data and voice. Back before Verizon got LTE there was no simultaneous voice and data. Then once LTE came along, suddenly simultaneous voice and data worked (and has worked for me since). The way this was explained to me was that voice uses CMDA and data uses LTE (which is GSM) so they can coexist.
So I guess I'm confused about two things...
1.) Since simultaneous voice and data has been working for years now, what makes these new phones (Turbo & Nexus 6, specifically) any different. Why is this suddenly a concern again? It feels like 2012 all over again.
2.) Whatever the reason is that it supposedly does not work, why will VoLTE fix things? It seems to me that once we have VoLTE we'd have voice and data both trying to use the same pipe and have issues again, just like before LTE existed and we had only CMDA.
Perhaps someone can explain

1. some newer VZW phones dont have two radios (ie, one for CDMA voice and the other for CDMA or LTE data).
2. VoLTE with one radio has enough bandwith to simultaneously handle both voice and data. However, VoLTE has a much, much bigger problem as I see it:
http://www.verizonwireless.com/support/advanced-calling-faqs/
Will my call be handed off automatically when I move from the 3G network to the 4G LTE network and vice versa with Advanced Calling 1.0?
No, calls won t switch between 3G and 4G LTE networks. If your call starts on the 3G network and you move to a 4G LTE coverage area, your call will continue as a 3G/CDMA call. However, if your call starts on the 4G LTE network and you move to a non-4G coverage area, your call will drop.
I live in Houston....presumably a place with lots of LTE coverage. In reality, I am constantly switching between LTE and 3G. with VoLTE, I'll be dropping calls like crazy.

[UNLOCKED - AT&T] Enable VoLTE, Video Calling, WiFi Calling and more?

My phone: Samsung Unlocked variant running on AT&T
Using a dialer code I've found an app "Testing" that shows options to enable the VoLTE, Video Calling, WiFi Calling & I'm able to pick network type (GSM, UTMS, LTE, ect.) Some options work and some don't. Maybe somebody smarter than me can look into this and possibly enable 4G LTE on AT&T, as well as the other features?
Code: *#*#4636#*#*
Awesome..thanks
have you tried calling at&t and asked about adding your imei for them to enable those on your device.
Thats what i have read online that tech support from at&t can make this service works with unlocked note 8.
Im still waiting for my Unlocked Note 8 and wondering how to enable Volte (HD voice). i dont use wifi calling that much though.

Changing networks does change my connection from 3G to HSPAP to no connection, depending on the option. The VoLTE, Video Calling & WiFi calling are temporarily enabled but then turn back off. Likely provisioning issue but that's all i can tell.

I have and they advised there's no issue. They can't seem to figure it out but I've spent several hours and multiple calls trying to determine if it's an issue or the way things will be.
The only interesting thing they advised of that there's no device description on my account. (Typically it'll at least say Samsung Note8 got example but they see nothing) IMEI and SIM were updated upon activation.
unless something has changed recently, you have to have an ATT phone for all of these features to work. i can only get HDVoice (VoLTE) working on my Note Fan Edition and my wife's S8+, both of which are Exynos devices. I had to call ATT and (a) have them assign the IMEI of an ATT phone (S7 Edge and S7 Edge +) to each account and (b) by flashing an ATT CSC (from a Snapdragon ATT S8+) to the Note Fan Edition and the S8+. The ATT CSC's enable options for Wifi calling and video calling, but these features aren't working on either phone.
Hows your data speed? Do you get 4G LTE speed data?
coz you said your connection is going from 3G to HSPA+

I average just under 5 Mb/s (Megabits, not megabytes which is about .5 MB/s) on H+ Latest test was 4.6 Mb/s
I do not get LTE, but am in a heavy LTE area (Phoenix, AZ) and get solid consistent LTE on my Note 5

WOW thats totally sucks! Im now worried about my preorder.
I might have to cancel my order from samsung and get an At&t brand note 8. I hope this is only a temporary problem with unlocked note users.
Thanks for all the info! good luck on getting all those at&t services.

I have an unlocked note 8 with an AT&T sim. I get great LTE speeds. In the city I get 100 plus Mbs at home or in the country I still get about 20 with only 2 bars of LTE i am only missing VoLTE and wifi calling
I'm hoping it's a setting issue on their end or something. I'm continuing to find a knowledgeable AT&T rep with some info. Good to know the unlocked version gets good LTE speeds. I'll get a new SIM and continue to look for a resolution. Worst case I'll flash radios as that looks like it's a developing option.
I gave up trying to jump through hoops to get WiFi calling and VoLTE and just bought the dang AT&T version when I preordered... If someone could come up with an easy way to get it all with an unlocked version...I'd be tempted to jump on it but until then, I'm stuck with the AT&T load.

That I wanted to be able to use wifi calling and it doesn't work. The went through and made sure all features were enabled.
I have spoken with multiple AT&T reps and after speaking with someone ('ha-seen' is how it sounded) who said that they were with the Level 3 team I was told that video and wifi calling are all proprietary to AT&T and that you have to have a branded phone with their build and that the unlocked version would not have access to this.

I got the same answer. I am calling and complaining to Samsung, I mean I pay to use the AT&T network and the features and the phone is capable of both volte and wifi calling there should be an easy way to fix this.
Just picked up the Note 8 U1 for use on AT&T, switching from a S8+ that was AT&T unlocked. I don't use WiFi calling, advanced messaging was cool but not having it won't hurt, I think. VOLTE is the big question, I know it's voice over LTE but how will that effect me talking and surfing the web at the same time?

Utilizing CDMA, on Unlocked Galaxy s5 AT&T Samsung SM N920A on GSM network.

Unlocked Galaxy s5 AT&T Samsung SM N920A on GSM network.
Stock Rom, Unlocked, on Android 7.0 (updated with Odin)
My goal is to see if this phone can indeed be used on CDMA.
Now let me back up.. I hear you. Most phones cannot be used on CDMA if they are GSM.
However if I key in the code *#*#4636#*#* with daler, (which is the Display information about Phone, Battery and Usage statistics)
I get to a menu that allows setting the ''Preferred Network Type''
is this a system setting used by mannufacture for setting the phone for market, and the phone itself simply doesn't have CDMA?
The specs for this phone
lists nfra: 2G GSM, 3G WCDMA, 4G LTE FDD;
Meaning this phone does indeed use both CDMA and GSM network, is this correct?
If so, how do I sucessfully enable it to utalize CDMA connection?
f not, why does the option for CDMA, LTE appear in the menu, along with many others.
I greatly appricate any responce on this topic

I to would love any information reguarding this. Same phone same specs. Was a little new to how the towers and unlocking system for each set of towers was defined when I unwitting traded my Verizon galaxy note 5 for and unlocked note 5. I was told the phone could be used on either set of towers and that it was factory unlocked and not just gsm unlocked. And that factory unlocked meant that it could be used with any carrier on any tower. Believing this to be miss information I had hoped to root the phone and find a root method for using cdma towers. I have being your own pho e service through straight talk so I had to switch my my sim back to and older phone wich not only is less advanced but also currently seems to be unrootable,because there are no gsm towers where where I live so I have no service at home and I'm out a note 5 and can't root my phone wich is a great dissapiontment for me. But when I open my phone it offers to allow me to choose those towers the same as yours. Someone help me stop this madness.

Unlocked variant on t-mobile

I have an Unlocked variant which I purchased directly from Samsung.
I don't happen to see VOLTE settings in my mobile networks setting.
Is this normal? I have seen another user post a screenshot from his/her phone which shows VoLTE setting (Telcel network) which can be turned off or on,but my phone doesnt have that.
I am on Tmobile.
tmobile phones have never displayed any VoLTE icons or notifications. Its carrier dependant on if they show it or not.
Unlocked US S10s has every Tmobile feature except Multiline Digits and probably their crappy RCS service
It's also missing the Tmo Video calling.
i have t mobile and always buy samsung international phones. volte, wifi calling,
video calling, and download booster usually dont work until i change the csc to tmo. i would think the ability to do so will be coming once the phone is rooted and out for a while.

1. Normal. The icon is disabled, but the feature isn't.
2. Yes. Testing VoLTE is as simple as placing a call. Phones w/o VoLTE will drop to 3G/2G OR fail if LTE is the only signal avail.
3. VoLTE toggle is missing. I sent feedback to Samsung about this some time ago.

VOLTE on Axon M in preparation of AT&T's 3G shutdown

With AT&T shutting down it's 3G network in a few months I was wondering if anyone had been able to get AT*T's voLTE (HD voice) activated so we can still make voice calls on the network. I have the AT&T model (and am using a tracfone AT&T sim), and "search" in the settings does show an entry for "enhanced LTE services" but selecting it just takes you to the same spot as the "more" entry and there is nothing useful for voLTE. When making a voice call data drops out of LTE, down to "4G".
Using a t-mobile sim (via tracfone), defaults to voLTE, verified also by surfing during a phone call, and LTE symbol staying on the whole time.
Hmmm weird, I can get voLTE with another AT&T MVNO (unreal mobile) by default, with no issues (also tested by surfing during a call and having LTE symbol stay on). I was not aware there could/would be differences in voLTE support among MVNOs
