Can anybody on T-Mobile confirm that VoLTE is working? I received the stock OTA a couple of days ago by removing the sim card first. Band 12 is enabled and gets engaged from time to time (I can see it using LTE Discovery), but every time I make or receive a call the phone drops LTE and changes to H and 3G. The Enhanced 4G LTE Mode option is enabled. Isn't it supposed to keep LTE during the call if VoLTE is working?

Enhanced 4G LTE enabled here, phone calls keep to the phone in LTE mode (as well as enabling high speed data while on calls)

Thank you for confirming this. I guess I will have to try with a different sim card.

Can you explain "Enhanced 4G LTE"? I don't see the option obviously anywhere in my settings, so it might be because I'm on AT&T at the moment, but I'm considering switching for economical and VoLTE reasons.
Also, could you give me any advice on whether I should be able to get away with a tablet SIM or if I'd need a phone SIM. If VoLTE and/or Google Voice work properly, I expect that I should be able to still make and receive calls. Is that unrealistic?

Anyone experienced that the phone just stop receiving any call at all but the signal bars are full?

I read these but it mentioned N5 only,
but I did experienced this problem couples of time in different days and it last for so long that I didn't know at all
(only found out when someone did leave me voice mail and it popup)
I am using 4.4.2 rom with hybrid modem LTE enabled,
I am trying with LTE disabled right now and see if the issue fixed.
If you dial *#*#4636#*#* it'll bring up a menu. Click phone information and make sure if you wanna use LTE make the selection to LTE/GSM auto not LTE Only. I've has that problem and i could receive calls or texts. If you wanna go back to HSPA+ use WCDMA Preferred. Hoped that helped

I use LTE/GSM auto already and this still occurs.
I am turning LTE off right now cox missing calls is more serious than having higher speed

It could be your radio, hopefully switching to use LTE every time you want to use it isn't that much of a pain

I followed the instructions like another thread comment said to do but for some reason I couldn't get it to work still but after playing around I was able to get it working.
---- Instructions for enabling: (thanks eyecon82) ----
1. dial ##3282#
2. then click edit (need MSL code) (I used SPCUtility.apk as nothing else worked on my S5)
3. then click LTE
4. It will show LTE ( also known as Band 25), Band 3, Band 26, Band 41 ( I unchecked marked all of these but the LTE option leave that check marked to on)
5. Disable all bands leave LTE check mark to say on.
6. Go to the main directory by hitting back key and choose More at the bottom
7. Choose HDR/1X Selection and choose LTE only Mode. Click OK to save
8. You can either reboot or I just turn on airplane mode and turn it back off to reset the connection.
9. LTE should be working like mine did. But you will not get phone calls until you turn back on the HDR/1X Selection to LTE + CDMA +EVDO Mode but you will get text messages fine.
The items that are underlined in Red are the stuff i added.
---- To tell what Band on: ----
1. ##debug#
2. enter passcode 777468
3. go to LTE engineering menu
I hope this helps because all the other stuff I read would not work for my Galaxy S5 I just bought.
Thanks
One more thing
I read on here http://s4gru.com/index.php?/blog/1/...-due-to-circuit-switched-fallback-technology/
that this problem should be fixed soon but if you need LTE now here it is.

Thanks for the info. However, I think its crazy to want to set it up for LTE when you cannot receive phone calls especially since this is you know, is a phone. Calling Sprint and talking about this situation is useless. They all say nothing is wrong and its the device. I'm really pissed off about this but I enjoy the phone. This will probably be the last Sprint phone I will get.

I use it at night or in places that I need fast internet and when I know I dont need a phone for a bit which is why I have voicemail I just switch over to LTE for a bit and then back...but yes it sucks for now until they upgrade the tower over here with the feature needed to use LTE spark devices.
Im loyal to sprint but its becoming more and more hard to be loyal.
Probably just your area, not the phone.
Your area may have LTE but if it doesn't have the circuit fall back enabled yet (tri-band phones) can't drop the data to allow a call and thus they force you to remain on 3G only.
Once your area has everything done it should get better.
I have similar situation that KILLS my battery at home but in every other part of town it all works great :/

Found out from reading the Sprint forums (https://community.sprint.com/baw/thread/157300?start=0&tstart=0), that this is likely not caused by the circuit fallback, but incomplete rollouts of Spark technology. Disabling the new Spark bands has helped me keep a stable LTE connection. Once the Spark rollout is complete in my area, and Band 26 can support both Voice and Data, I'll re-enable it the new spark bands.

Which bands did you disable? Also, are you able to get voice calls when you LTE?
Im a bit frustrated be the place I spend most of my time (where I used to get LTE fine with my S3) I no longer get LTE and its super slow 3g. Calling sprint didn't help, they just say to wait until cell tower updates are finished in the next 6 months.
If I disable the Spart bands, will I be able to keep LTE and voice? Thanks

I disabled bands 26 and 41. This forces the phone to use the default sprint LTE band. It receives voice calls just fine.

LTE works fine because it defaults to the standard LTE band.

Read the sprint link. Incomplete rollout of spark, in particular on band 26 can cause the issue of not being able to switch between 4G and 3G and back.
One of my friends came from overseas a few months ago with VoLTE working on Tmobile US. At least I thought it was.
I did not think much of it at the time, but now that I have my own Z5, and can't get it to work, I'm curious.
Is there any special APN settings needed for VoLTE on TmoUS?
WHen i received my Z5, I noticed there was not any option for VoLTE. I went ahead and flashed the a singapore rom and it is here now but still cannot get it to work. I will try different settings and update.
I am also going to go through a few more roms to see if they work out of the box with it.
WIll it not ever work unlesss TmoUS certifies this device specifically? I don't think that is the case.
It's carrrier dependant
VoLTE uses the SIP protocol for communication. Aside of the implementation of the handling of such calls you would need the necessary data for registering at the server including the server's address, username and password.
I bought my international version from Amazon and turns out it is a Taiwanese version.
I can turn volte on or off but I can't tell it is working or not cause I don't know how to test it.
Testing it is pretty straightforward. Make sure you're on a 4G (LTE) network and place a phone call. Watch to see if you're signal changes to something other than where it started.
My experience is that I have 4G (LTE) in fewer places than 3G, as 4G seems to be less awesome at penetrating thick buildings. So, I don't see what the advantage/concern of VoLTE working or not is. But, I'm happy to learn.

When I make a call, the icon switch from 4G into 3G and H+ (back and forth between the two).
Does it mean no VoLte?

I have the same question too.
That's my understanding of the problem. With my AT&T iPhone, it stays reading LTE when I place calls.
If you see switching from LTE to another network upon dialing or receiving a call and going back to LTE once hung up it's a very strong indication that VoLTE does not work.

THat is correct. My phone switches from 4G to H+ when on a phone call...
After many hours with t-mobile, and also at work, i was informed that t-mobiles VoLTE is proprietary and only tmoUS branded devices are usually the ones to get VoLTE to work with them.
Maybe in the future that will change, they said. oh well.
Until now every provider's solution is proprietary as the 3gpp standard is not finalized yet. So we need to be patient...
My network doesn't currently support voice over LTE (VoLTE) so everytime I receive a call my signal switches back to 3G (H) or 2G (E). I noticed that after a call, it takes time for my S8 Plus to switch back to LTE. Is there an engineering or advanced configuration settings that can be set so that after a voice call the signal goes back to LTE immediately?
This maybe not an impossible thing because I noticed on some other mobile phone brands that the switching back to LTE signal after a voice call is kinda fast (within 2 to 3 seconds) after a voice call.
Thanks
I had a Sony Xperia Z3c on T-mobile. It was an unlocked phone. When I made a call it would switch to 3g because the phone does not support voice over LTE. Most of the time it would take a while to switch to LTE again unless i went into airplane mode or turned data off for at least 10 seconds OR what seemed like if I was driving maybe it would connect to another tower.
So maybe it's normal with phones that don't have VoLTE?

Hi! I am experiencing faster switching on other brands like Huawei and LG. They switch from 3G or 2G to LTE between 2 to 3 seconds after calls.
And yes, that is correct. I usually switch my phone's airplane mode on and off to get the LTE signal back faster.

Cool
On Sprint's Network, unlocked bootloader & critical partitions. Anytime I even receive a notification for a phone call coming in, my LTE is dropped instantly. Deny or hang up the call, it comes back. I've read that Sprint's 3G can't handle voice and data at the same time, but this is 4G. Wifi is also completely useless on this phone as it stays connected for about 60 seconds tops.
Tried doing a complete wipe and reset to both Pie stable and Q beta 6, same exact thing. Tried all the network options in settings and nothing.
Does anyone with Sprint have working LTE during a phone call? I'm trying to figure out if it's a **** copy I got from Amazon, or the network. Thanks.

I have the issue. I also can't get LTE+ to work either. I'm on Boost, but they use Sprint. All stock roms and I can't get 4G at all on custom roms. I bought mine directly from Essential.

I can't say anything about Sprint, but VoLte on Verizon behaves the same way for me on Q beta 6. If the radio cycles for any reason I lose VoLte even if it shows selected. I have to toggle it in network settings for it to work.
Just curious, if you go into the phone info with *#*#4636#*#*, does it show that VoLte is provisioned?

It's grayed out for me. I can't enable it. Maybe calling Boost customer service might result in fixing it.
