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

Any one else loosing LTE data and droping to hspa while on a call. Happening to both my vivid and skyrocket.
Located in Houston, Tx
The reason for this is that, currently, LTE is data-only. Until LTE providers begin to deploy Vo-LTE (Voice over LTE. Basically VoIP, on and LTE network), the only way you will be able to engage the voice stack on your hardware and access data at the same time is if you fall back to UMTS, which has always integrated both services (voice and data) together.
Unlike Verizon lte, art lte uses circuit switch fallback. Can't do hspa and LTE at one time.

THAT SUCKS ATT!!!! I have to talk & use internet on the HDSPA+ network....it seems so slow. Am I the only person this happens to?
It happens to *everyone* because that is the way it works. Notice that every time you make a call the "LTE" tag goes away....and stays gone until you hang up and the phone reselects back.
There will not be any LTE voice until an IMS is up and running...

I know its data only. But dont see why it has to drop off. I have been playing with the build.prop. And it has
#device supports simultaneous 1x voice + LTE
#ro.config.svlte1x=true
So i guess at one point we will have this ability.
This phone only has one radio built in and can't run on both UMTS and LTE at the same time.
I think that setting is referring to a Verizon type LTE device. They have two radios and don't do CSFB like the Vivid/Skyrocket.
Each phone type has it's own pros and cons.
Well, I'm going to be doing some international travel in the next few weeks, so I picked up a T-Mobile SIM card for my Verizon Moto X Developer Edition.
The good news: The device supports T-Mobile's LTE band and registers/displays LTE.
The bad news: The LTE implementation does not seem to be at all reliable when on a GSM-based network.
1) I had a hell of a time trying to get it to accept a GSM conditional call forwarding code -- it would just immediately close the Phone app and I would temporarily lose mobile data connectivity. When I disabled LTE, it worked.
2) When I make a call while on LTE, the mobile data drops as soon as I dial. Google Voice dialing never works (app immediately closes with no mobile data) and standard dialing often just immediately closes the phone app. If I re-initiate the call after the LTE connection has dropped and before it recovers, it will sometimes work.
All of this is resolved when I force the phone into 3G-only mode. From an HSPA connection, both of the above seem to work fine.
My theory on this (maybe I'm off base) is that the handoff/fallback that's required for the phone to use a CDMA network for voice while on an LTE network is somehow still triggering -- and obviously not working for GSM.
Things I have tried:
- Setting preferred network mode to " LTE / GSM / UMTS "
- Resetting APN settings
- Clear Dalvik and Android caches
- Disabling Xposed framework
Things of note:
When I boot the phone for the first time, I receive this message:
"Sorry - This SIM card is from an unknown source"
After I acknowledge it, no problems other than the above.
Would love some pointers on what I could try to resolve this... anybody else have this scenario and had issues like this -- or gotten it working?
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

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.

No sprint spark phone can do it .... g2 g3 note 4 s5 none of them
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.

Hello,
I've searched the forums and haven't found an answer to this issue I'm having.
I have a Huawei P10 Plus VKY-L29 model and I'm having issues connecting to LTE on T-Mobile US. In areas where is it supposed to be LTE, the signal displays "4G+". I know there's the argument that 4G+ is LTE but then there's the problem where other people are on LTE and I will be on 4G in the same area. Also, whenever I make a call (whether on 4G or 4G+) before the call begins to ring, it will revert to nothing higher than 3G and then connect the call. This is an issue because my phone will also not receive calls unless 3G is available (which is not always the case) and will send the caller straight to voicemail and I will get no notification that they called unless they leave a voicemail. I assume this is a VoLTE (Voice over LTE) thing. I want to note that I do have the Virtual HD call move enabled in Dialer settings. There is no VoLTE setting in the device though. I was searching for the engineering code for Huawei devices in case there's a "LTE/4G/3G/2G" option that is not enabled but have not found one that works for this device.
My device is not rooted.
Please help!
Thank you!

You have to check your carrier whether they enable and support VOLTE for P10 plus. My carrier in my country only support few mobile devices for VOLTE and including P10. VOLTE is a service provide by carrier. Not phone. Hope it helps.
I bought a SM-N960U1 unbranded US unlocked model, and I immediately updated it to Android 9. THEN I inserted my T-Mobile sim, and I have wifi calling. I did all of this a few weeks ago, and I never really questioned it all until today.
I'm posting this now because I read that people cannot get wifi calling to work on their unbranded model unless they flash carrier firmware.
And this is what I've found. When I make a call while connected to wifi, I see the little wifi symbol on my phone symbol, as if the call is a wifi call. I have a toggle for wifi calling, which works! If I toggle wifi calling off and make the call again, no wifi symbol on the phone symbol. When I look in settings > connections, I do NOT have items to set wifi calling and VoLTE. However, I can search settings for wifi calling and I will find the Samsung 'Wi-Fi Calling' app (com.sec.unifiedwfc 6.0.33.47) RUNNING!
So, it seems I have wifi calling working on T-Mobile, with just the Samsung stock firmware and not the carrier firmware. Which is great! No carrier bloat.
I just tested my wifi calling by starting a wifi call and then walking out of wifi range, and it definitely works! At the edge of wifi range, the call broke up, handed over to the cell tower, and became noticeably less clear. I'm stoked to have wifi calling without carrier bloat.
I might investigate further if there are some settings I can toggle over adb (wifi preferred, etc)
It depends on the carrier. T-Mobile does support all of its services, including WiFi calling, on the N960U1. Some other carriers do not. Always check with your carrier before buying an unbranded phone.
I also just discovered that toggle button text is CLICKABLE, and I can access Wi-Fi Calling SETTINGS when I tap on the wifi calling toggle's text, which gives me the option to turn on/off wifi calling, wifi/cell preferred.
So I have Wi-Fi Callng, can change settings, all in the stock non-branded firmware of the SM-N960U1.
AWESOME!
