Last I saw, it appeared that OTA Marshmallow 6.0 on Moto X Pure Edition had voice call problems with VoLTE enabled, on T-Mobile.
The workaround was to disable VoLTE (Disable "Enhanced LTE"), to maintain good voice calls quality.
Can anyone offer info on whether this is still a problem with OTA MM, T-Mobile, and VoLTE?
I'm staying with 5.1.1 until I see this resolved, either on T-Mobile end, MM, or maybe with a fix to some offending component or app.
TIA...
Please everyone let Motorola know about this bug so that they will fix it.

I read that thread a while back. My conclusion was there was insufficient resources when the screen off when on VoLTE. I'd think using a kernel manager with a custom kernel would let you set a higher cpu speed with the screen off, or maybe enable more cores to be available.
There still no fix for VolTE voice calls bug on this phone?
No fix. Motorola/Lenovo is basically ignoring us. You can see this in the long running Motorola support forum thread. Kernel change does not help as it has been tried already. Moto sucks.
That's a bummer. I think I'm going to return it before I loose the window. My last phone was an LG G2 and the VoltE worked flawlessly. It is sad that a newer/better specs phone is worse in that area than a 2013 phone.

If I downgrade to KitKat the bug will still be there? Or maybe use another modem/radio?

KitKat does not exist for this device. Lollipop does not have the VOLTE bug. But you will loose band 12 LTE.
I don't think this is a Lenovo issue. I'm on AT&T and pretty much they only support VoLTE on their branded phones. Blame your carrier, not the phone. VOLTE does work on Verizon as I know two other people with this phone on VZ and once they got MM update, it worked.

That could be true. T-Mobile tells me they are aware of it.

I don't want to jinx myself but I have had my XT1575 (US) since October but recently switched to T-Mobile from VZ. Although my bootloader is still unlocked, I am running stock 6.0 (24.201.3 - Feb Security Update) and have had zero VoLTE issues (even on VZ it worked fine once enabled on my account)... Still no Wifi-Calling (on either carrier) with my XT1575, but HD Voice works great when calling another T-Mobile VoLTE phone (HD icon appears and voice quality/audio range is noticeably improved).
Not to state the obvious, but have those of you with VoLTE issues go into the hidden "testing" menu and made sure the VoLTE Provisioning Flag was set to "ON"? Access the Testing menu by entering these keys from the dialpad: *#*#4636#*#* and go under Phone Information then scroll down...
Also, make sure you have the T-Mobile LTE APN (Access Point Name) configured and enabled (should be auto-provisioned as "T-Mobile US 260 LTE" but if not the APN is "fast.t-mobile.com" and there are instructions for manually configuring their APN on their website).
Hope this helps.

VOLTE Provisioned flag is set. APN is correct.

It really doesn't matter if you upgrade the phone from Lollipop because VoLTE didn't exist on the phone until the Marshmallow upgrade. If you have problems with calls you can turn VoLTE off which is what you have now.

It does if we want to make calls on LTE band 12 as this band only supports VOLTE for voice.

I think you misunderstood what I said. VoLTE was not added to the phone until the Marshmallow upgrade. If you are still using Lollipop VoLTE doesn't exist.

Your move from VZ to T-Mobile may support it is a carrier thing. Perhaps because your phone was already provisioned to with VOLTE on VZ, it carried over. I know the phone supports it, but let's face it, U.S. Carriers seem to hate not having control (especially AT&T). Any means to keep features limited unless you use their branded devices is one more control they have.

I understood what you said. But band 12 opens up a larger coverage area. Without VOLTE calls do not work on band 12.
One thing to note is that if the screen is kept on the jitter goes away. So it may also be a power management issue. We have already tried disabling power management on call services. But it did not help.

I am not disputing the fact that you need VoLTE to make calls over Band 12. Fortunately where I live in the Boston area T-Mobile pretty much operates exclusively on Band 4. So if I start having call problems with VoLTE enabled I can just turn it off. However, if I was still on Lollipop and in areas of the Country that use Band 12 exclusively I would not be able to make any cell calls using T-Mobile, since VoLTE was not enabled on the phone until the Marshmallow upgrade.
I would like to be able to blame T-Mobile for the problem but unfortunately this doesn't seem to be the case. Other third party phones like the recent Nexus phones, the Axon Pro, and the iPhone 6s and 6s plus all seem to have no problems making voice calls with VoLTE enabled. In my case I have noticed that the static problem does not occur with every call. It seems to come and go on an intermittent basis.

I agree that it seems to be device specific. It sucks that Moto is ignoring the issue.

I think we all agree that Moto ignoring the issue is the worst part of the situation. I don't think they have even acknowledged it as a problem yet. There are a lot of things about the phone I like. However, at this point I would never buy another phone from Motorola. All phones have minor bugs. However, this is a major problem.
Guys this is a very difficult one. I really appreciate your help. If there's any place I can get an answer I think it's here.
My Nexus 6P had the Wi-Fi: option in the settings, I saw it many times. However after activating the phone with Sprint (during the process the agent Keith something into my phone which caused it to download and install something from their system) the Wi-Fi calling option is gone from the settings. I've tried everything I can think of to get it back and have been unable to.
I have a very new Nexus 6P running 6.0.1. I purchased this phone especially for its Wi-Fi calling capabilities to use on the T-Mobile network. At the time of purchase there was a lot of conflicting information about Wi-Fi calling coming from T-Mobile's customer support/technical support and numerous support people were saying the 6P is the only phone they were sure would work. I used the phone on T-Mobile's network with Wi-Fi calling and the Wi-Fi calling worked flawlessly, but there were other problems with their service so I moved on to Sprint. Sprint's Wi-Fi calling was horrible, in fact I don't think it was really doing Wi-Fi calling, I think it was just calling to the cellular network. During my time with Sprint I noticed that the phones Wi-Fi calling settings were gone. I contacted Google and they said that if Wi-Fi calling is not allowed by the carrier then the option would not appear in settings. I don't know if that's true but that's what they said. I assumed moving onto Verizon which does offer Wi-Fi calling would restore that option if it was just a matter of having a Sim card which commanded the phone to enable Wi-Fi calling. However after switching to Verizon I still have no Wi-Fi calling settings, and I am unable to make Wi-Fi calls.
In an attempt to get my Wi-Fi calling features back on the phone by factory wiped the number of times from recovery, I also upgraded to android N beta, I also routed the phone and tried installing Cyanogenmod, I also installed pure nexus, I also returned back to the stock Marshmallow, and nothing restored the Wi-Fi calling option on the phone.
I believe what the Sprint agent dialed on my phone to cause it to download and install something from their network is ##72786#, though the agent also dialed ##873283# and ##675#.
One of the Verizon technical support agents suggested that I dial *#*#72786#*#* but when I do that nothing happens except what I dialed clears out of the dialer. I used one of the apps to discover secret codes on my phone and it shows that code is handled by an application called SprintDL. I know some people whose Nexus 6P have never been on the Sprint network also have that application, so I'm not sure if that is something that was installed during the activation process with Sprint.
Now I'm wondering if I need to reflash the vendor information or the radio modem information part of the ROM. It seems like all the roof flashing that I've done would have flashed over everything that could be flashed. But it does seem like something happened to my phone, something was installed or changed or replaced and whatever that is is surviving through multiple factory wipes and ROM flashings.
Sorry for going on, but I want to pass along everything up front so I don't receive irrelevant responses were requests for more information.
I will be so grateful of anybody can help me out of this mess. I live in a place with very poor cellular coverage and Wi-Fi calling is critically important. If I have to send this phone back to Huawei all have to purchase another phone to use in the interim.
Thank you in advance.

Verizon only offers WiFi calling for approved phones on there network. I do not have that option either with my 6p on Verizon however my wife's Galaxy S7 does.

Surely you jest. But of course.
Honestly, do you think someone who's rooted their phone and has flashed a number of different ROMs wouldn't know or how to look in the settings?

Thank you so much! So you mean that:
A) your phone has the Wi-Fi calling option in the settings but it does not work with Verizon?
– or –
B) because you are on the Verizon network the option for Wi-Fi calling does not show up in your settings?

I do not have the wifi calling option in my settings. I've always been with Verizon so I haven't tested it with another network to if that would change. I wish I checked to see if it was there before it was activated but I didn't. I'm fairly sure the option just doesn't show up if the network doesn't support it.

Thank you so much! That is so great to know! I know that my setting for WiFi calling was there because I received the phone and played with it before I activated it and the setting was there. It was there when I was with AT&T and with T-Mobile.
I just found out what the problem/solution. It's the sim card. Today I purchased a T-Mobile sim card and even before it was activated, as soon as I popped it in my phone presented a notification about wifi calling and sure enough I checked the settings and the wifi calling option was back.
So if you have a 6p and the wifi calling option is not visible it's because of your sim card. Removing the wifi calling disabled sim card, rebooting the phone, reflashing the rom/firmware does NOT restore the visibility of the wifi calling option. The only thing that will restore the visibility of the wifi calling option is to insert a sim card that is wifi enabled.
I wish the good folks at Google or Huawei knew that the wifi calling setting's appearance or disappearance is tied to the sim card. It would have saved me a lot of work and headache
So having installed the sim from T-Mobile got you back the Wi-Fi settings back but when you put back the Sprint/Verizon sim did it remove it again or not? And if it didn't did Wi-Fi calling work on Sprint/Verizon? Or do we have to call and order a Wi-Fi enabled sim from our carrier?
Hi guys,
I bought the unlocked firmware phone back in December 2016. The phone is great, the problem is I am using EcoMobile MVNO. It's refusing to recognize the network with the MVNO's sim card. I've spent hours on the phone with them and they claim all is OK on their (and Verizon's) end.
The phone sort of works, so I've just been grinning and bearing it so far. Using 4G switcher, I can put it in CDMA only mode, in which case it connects to '123456' and I can receive and make calls, and receive texts, but have no internet. If I put it in full LTE/GSM/CDMA auto mode, it connects to LTE, so I have internet, but it claims I'm not connected to Verizon network and in fact it's not available. So in this mode I can't receive calls or texts. Can't send texts under any mode. I've done a full factory reset at the MVNO's behest, of course that did nothing. The phone seems to connect fine to Verizon's network if I borrow someone elses's Verizon sim. My MVNO sim also works in my wife's iPhone5 without a problem. So it really seems to come down to the firmware on the phone. I'm holding out against hope that when Nougat comes to the G935U firmware, this problem is magically solved... but just in case decided to post here.
Please help, any ideas would be appreciated.

Flash the vzw firmware or go through the steps for the hybrid rom with vzw modems implemented.

Welp, the 7.0 update is here, and it didn't fix my issue, in fact now I can't even get LTE data as I used to get. :crying:
So I had this issue when I first got the nougat update. When I got my S7 I put in my brothers sim card to made sure it worked on Verizon cause i was buying it from someome and anyway I activated my straight talk verizon SIM and everything was great until I got the update and my service was weird and I didn't know what to do and then it dawned on me, I put in an actual verizon SIM card, doesn't need to be active let it register and then put your SIM back in and everything was great! Hope this helps...
Switched to TotalWireless, phone works now. They first sent me a SIM which didn't work, then had to send a different, post-paid one.
I now suspect if ECO also sent me a postpaid based SIM it would start working. Things are always way too complicated when Verizon is involved.

I'm tempted to try this as I'm having the same problem with my 935U and Xfinity Mobile (Verizon MVNO) SIM, instead of connecting to the Verizon network, it connects to network 123456. I did load the 935V firmware, which worked fine, but I'd prefer to return to the U firmware if this would work. Is this still working for you, and if so, do you just need to put the regular verizon sim in once and from then on the MVNO sim will work, and continue to work including after a reboot?

I put in a Verizon SIM in it once and that was after the nougat update. But every time the phone restarts, I have to make a phone call for it to connect to the service or it will just stay stuck in "searching for service" but once the phone call connects, I hang up and everything works as it should.

Thanks, strange problem. I'll probably just stick with the 935V firmware for now as that's working fine (just have the Verizon bloat and failing the hotspot check). I also have a dialog going with Samsung support to see if they're aware of the problem and have a fix.
Is it possible to get volte working on Unlocked Firmware S8+ with straight talk at&t
I've got a att s8+ phone as well as a tracphone s8+ which are both on the unlocked firmware and upgraded to the oreo latest beta. I'd like to get volte working but not sure if it's possible.
Thanks!
Actually may have found a work around to make it work myself and this may help others.
I was able to put in a T Mobile Sim which rebooted the phone and added whatever settings. Then once it was booted, I put the straight talk sim back in. The volte menu option was not under mobile settings prior. If you click volte off, it will disapear. If you leave it alone, it keeps it activated. I turned off the phone and on and confirmed, it retains it. Called a friend who I know has volte and you can tell the connection is volte. It appears atleast to me that the sim turns on the option and the straight talk sim alone does not support lte but the network does.
Good info, thank you.
Hi all. Posting this for users looking for answers on VoLTE and WoWifi on the 6T on AT&T & Verizon. If users with access to the OP6T could please test and report, that would be very helpful. Since the pixel 3 now supports both VoLTE & VoWiFi (on AT&T) there is perhaps some hope that OnePlus will also support it.
1: On AT&T, is there an option for Voice over LTE and Wifi calling and does it work?
2: On Verizon, I know Voice over LTE will work, but what about Wifi Calling?
Screen shots welcome I will have my hands on the device as soon as its available and will report since I have all the carriers, but thought maybe someone might get their hands on one early and could report. It might make a big difference on whether or now some users buy the device.! Thanks guys!
Yeah, whether or not I get the OP6T depends entirely on whether VoLTE and VoWiFi work on AT&T.
Eagerly waiting for updates!

Same here!
AT&T & Verizon VoLTE and VoWiFi calling/texting thread
Same here. I’ve got a spot in SC where I got for holidays annually where, without Wi-Fi calling, my phone is a paperweight. I’ve always wanted to try a OnePlus but if there’s no Wi-Fi calling I’ll have to pass and stick with my XS Max.
I’ve already ordered but it’ll be a quick turnaround if that doesn’t work.

This question came up in the AMA with the OP team in their community forums last week, and Pei himself said VoWifi isn't supported at the moment.
Just got my device today so update time..
1: VoLTE works on Verizon by default as soon as you pop in the SIM. All the Verizon LTE bands seem to work fine.. in this area, 2,4,13, & 66. no option in the menu for wiFi calling, even though it works fine in my pixel 3 where my verizon SIM just was.
2: Neither VoLTE or VoWiFI work on AT&T by default. No option for either in the settings at all. So no change there from OP5/5T/6 ETC. However, if you go do the dialer, dial *#800# and hit enter, select oneplus logkit, scroll down to function switch and select it, and check the box for VoLTE switch and Vowifi switch and then reboot, it puts the VOLTE setting and VoWiFI setting in for both the Verizon and AT&T SIM. and while you can enable VoWIFI on both Verizon and AT&T, it DOES NOT work on either. On AT&T however, as long as you have a VOLTE capable/recognized IMEI on your AT&T account for your line, VoLTE/HD voice work just fine.
So, while it is amazing to have, for the first time ever a DUAL SIM phone that supports both VZW & AT&T at the same time, it is a too bad that VoWiFI does not work on either, Especially now that the Pixel 3 Supports it on both carriers.

Has anyone used the dialer code *#*#4636#*#* & try to toggle VoLTE &/OR VoWI-FI ?
Thanks for the info. I'm looking to get the 6T to use on AT&T. I've never used an unlocked/non-AT&T branded phone on my line. Are there any other limitations that AT&T implements on non-AT&T branded devices? Do they throttle data speeds? Any issues with SMS/MMS working like some Verizon users are experiencing? Would I need to contact AT&T to have any special provisioning just to get it to work? I appreciate any insight on this.

I'm not on AT&T so,I'm not gonna speculate.
Perhaps someone will chime-in soon for more definitive information.
My OnePlus 6t came in today. Took sim out of my Pixel 3 XL and popped it in. Everything is working except I can't SEND text messages. I can receive them and make calls, data is fine (actually amazing 44.5 mbps d/l, which is good for around here.)
I've tried chatting with Verizon, but after I told them what device, there was a long pause and then she asked if it was an iPhone
Here are my troubleshooting steps I've followed.
-deleted app cache and storage
-reset device
-factory reset device
-cleared cache partition in recovery
Any suggestions? I put the sim back in my Pixel and all the messages came through. I've tried both slots.
Mobile network state-Connected
Service state-In service
Mobile voice network type-4g
Mobile data network types-4g
EID-unknown (??)
There is another thread discussing why a lot of people using 6T on Verizon having problem receiving SMS and MMS. Something the phone being LTE only on Verizon. Maybe you are having the same problem? Worth reading that thread.

Yes. that would be best. I didn't need to do anything with mine, it just worked. However, I do have the latest version the the Verizon SIM card. Not sure if that matters. I was using a Pixel 3 before.

I have used AT&T for years on unlocked devices. I have tested everything Data speeds are just fine. no issues there. the OP6T supports all the bands on AT&T so coverage should be just fine for you. The limits are as follows:
1: built in visual voicemail will not work, you will need to use the AT&T visual Voicemail app from the store.
2: Wifi calling/texting will not work
3: VoLTE/HD Voice will only work with the above mentioned trickery. Root is NOT needed. just the *#800# thing
the only provisioning you may need is the AT&T imei for VoLTE (Easiest to do online) after installing your AT&T SIM in the OP6T, if VoLTE doesn't work after following the instruction in this thread, log into your AT&T account and update your IMEI to one of your past AT&T phones that support VoLTE and update, reboot you OP6T and bingo, it will work. No other provisioning or limitations that I know of. And if VoLTE/HD Voice isn't important to you, you can ignore all this. Your existing AT&T SIM just needs installed in your OP6T and your good to go!

The *#800# enables all those options. But it doesn't help anything on Verizon, and on AT&T it does work for VoLTE if a VOLTE enabled IMEI is on your AT&T account, but it doesn't work for wifi calling. I wish it was just illegal for the carriers to block services just because its a non branded phone

So glad that I found this post. I am coming from an AT&T branded Galaxy S8 to my new OnePlus 6T. The above instructions worked like a charm for AT&T. I ran some tests. The OnePlus displays "HD" when I call my wife on her phone on AT&T and VoLTE shows in the status bar. When I toggle it back off I lose "HD" on the phone call screen. Also, LTE stays on during calls with VoLTE turned on and I ran a speedtest with it on and off and I definitely get 4G speed with it on and it downgrades to HSPA+ with VoLTE off and speed goes way down. Hopefully VoWIFI will be supported soon but that's not a deal breaker for me as I get great reception most of the time where I live, work and travel.

I am on att had it all working on my unlocked NOTE 8. Now I can't even get volte cause it's all grayed out.
The service providers don't want you to buy unlocked phones. They make zero on them!! So that's why they block stuff. It's an antitrust lawsuit waiting to happen!! A$$h0!€$

I've got AT&T as my primary and Verizon as #2. I just got off the phone with Verizon, told them I needed to add the CDMA Less feature to fix my texting. He checked a box on his end and I got a flood of texts in...what was even better, it was a work phone on a business account. I didn't even have to provide any real information to him and he was able to fix me up. He was aware of the issue though, he'd asked if it was a 6T from T-Mobile...so someone sent out a bulletin somewhere that he had read.
Anyway, I left Verizon to go to AT&T specifically for this plan of having one phone to cover 2 lines while one being fully functional (AT&T), so far it's been working well switching between SIMs for texting and making phone calls.
What were you specifically looking to find out?
Edit: found what you're looking for...however I'm not sure where those settings are even at.
