VoLTE on AT&T - Google Pixel XL Questions & Answers

Has anyone gotten this to work? CS told me that I could use it as long as I picked up a new sim. It doesn't appear to be working though. The guy in the store wasn't sure. He has no idea what the pixel was.

I was once told only phones sold by AT&T could get VoLTE

I also have att but I just assumed volte would not work with our phones, same as how an international s7 volte wouldn't work with att, would be awesome if we were able to get it working, but not holding my breath

The care rep was wrong. VoLTE (and HD Voice codec) are both limited based on device IMEI. If your device isn't on the list you're not going to get these functions (and probably not RCS down the road either).

This is correct, ATT doesn't allow HD Voice on any non-att handset. However, They do still allow VOLTE supposedly. Just not HD Voice on VOLTE. Had the same issue with my Nexus 6p on ATT. One of the reasons I switched to Verizon.
Remember VOLTE != HD Voice. SD calls can be carried on LTE.

I just did a chat and the guy tried everything he could to get it to work. He ended up having to tier it up to an engineer. I'll update everyone as this progresses. I haven't been told no yet. So, I'm going to keep trying.

Mis-information exists in this thread. There are in fact non-ATT branded phones that get VoLTE and enhanced services. For the Pixel/XL, though, the outlook is not good. See these threads:

AT&T's VoLTE/WiFi Calling or T-Mobile's EVS on Pixel XL?

For those who are on AT&T and got their Pixel XL, are you seeing VoLTE and can you enable WiFi Calling?
For those who use T-Mobile, we know it supports VoLTE and WiFi Calling on Nexus, so Pixel will likely follow. The important question is whether it supports EVS (Enhanced Voice Service). I don't know how you would verify. An "HD" symbol during a call would be a good start.

I believe Tmobile and Verizon confirmed the google versions will be fully supported with HD, WiFi and VoLTE.
AT&T, that i know of, has never supported their advanced services on any phone that is not their brand. I know a lot of people with the P6 couldnt get wifi, VoLTe or HD voice. Verizon or Tmobile would be the two choices if you want to use the advanced features.

I agree with the state of support for T-Mo and VZ.
AT&T in fact supports non-branded iPhone 6, iPhone 7/+, HTC A9 and A10. The irony is that the ATT-branded Nexus 6 do not get VoLTE because, so I've read, Google would not bake in AT&T's proprietary VoLTE implementation. It is true that the 6P/5X do not get ATT VoLTE, but I am curious to know if things changed with the Pixel. If HTC can do it, then it is a business decision for Google/ATT.
For T-Mo, I would like to find a way to see if EVS is in use during the call. The chipset in use certainly can support it.

If your call was truly using VoLTE, you'd know for sure. My wife has an iPhone 6 plus, and when I got my Note 7, the call clarity is AMAZING on VoLTE. It sounds more like you are Skyping someone on a high-quality connection. Now that I'm looking for something to replace the Note 7, I really like the Pixel XL, but losing VoLTE on AT&T is a BIG drawback for me.
If AT&T does get around to allowing VoLTE on the Pixel, I'll order one today!
The verizon version is working out of the box on T-mo with Volte. No APN editing needed for those who maybe wondering.

If your 5X on AT&T stays on LTE during every call, run a speed test to verify. Note: Tmo DOES support VoLTE on non-branded phones, including the 5X.

VoLTE does not necessitate the wide band conversation you experienced. What you experienced was HD Voice, which is only implemented over VoLTE. Because the N7 and iP6 both support HD Voice, the conversation in HD Voice. Both parties have to support HD Voice and be on ATT (same for VZ). If you call someone outside of ATT, you will still get VoLTE, but not HD Voice.

Not entirely true. My buddy has VZ, and we had an HD Voice call between my Note 7 in Indy and his S7 Edge in Houston. Apparently AT&T and Verizon are now offering inter-carrier HD voice "in limited markets."
Once you experience it, you won't want to go back.

You're right, ATT/VZ are working on HDV interoperation. I haven't seen it here in L.A., but it would be nice when it works across carriers. It is matter of time... The same goes for ATT and VoLTE on non-branded phones, we just don't know how long they will hold out.
Just tested: No VoLTE on AT&T. Draw your own conclusions about AT&T.
As expected, Pixel XL on T-Mobile has VoLTE and WiFi Calling. I made a call to another T-Mo phone (Samsung) and it showed HD on both ends. I know the Samsung phone is using EVS, but wish I can tell if the Pixel XL is using EVS or AMR:WB.
ATT Support Wifi Calling and Volte for Google Pixel.
I would suggest for everyone who has att and the google pixel just call technical support and open a case.
After my call they said that they fully support wifi calling and volte on the google pixel.
They are currently working to correct this. Maybe if everyone starts calling it will add someone urgency .

I had to call them anyway for something. Will do this while I'm on the phone with them. Thanks!
I just called today and one lady told me that they do support the Pixel so she transferred me to another support specialist and then that lady told me that the Pixel is not supported. These people need to get their **** together.

Tmo Volte and HD voice calling work right out of the box. I would however recommend configuring your APN to the recommended one from Tmo. Internet access is the same but it seems MMS configuration is handled a little differently. I was having allot of issues with MMS not sending or taking forever. It's almost instant now
+1 to no HD Voice on ATT. As soon as I put my ATT sim into my old 6p I lost HD voice (Had a note 4 before it, That DID have HD voice). At the time I also did not have VoLTE (Phone would fall off LTE when on a call). At the time, They claimed no non-ATT phone would support VoLTE and HD calling. I've verified since then and have found the same to be turn currently. Including with my Pixel XL.

Yes, At least here in Central Florida. I've got a VZW Pixel XL. My mother has an iPhone 6 on ATT. Every call she makes to me is AMR:WD (HD). However any call I make to her is standard AMR. I've spoken to about a dozen VZW engineer's who all claim it's coming. And for now, They're only allowing AMR:WB setup on inbound calls, But not allowing it on outbound call setup.
Although Pixel gets VoLTE on T-Mobile, disappointingly, there is no EVS/HDV.

WiFi Calling and VoLTE and AT&T

It's my understanding that these features (advanced calling, like WiFi calling and VoLTE) Doo not work on unbranded devices like Pixel and others. This was the case with my unbranded SM935F or Galaxy S7 Edge until we got some files, an appropriate CSC, and also had AT&T switch our account to an IMEI of an AT&T branded device that had working WiFi Calling (others have apparently just called AT&T and had them provision WiFi Calling)
Note: for me, I have a business account so I could just go into my business portal and put in an IMEI that I got from an S7 Edge model in an AT&T store
I am attaching the files that we needed to add to our system to get WiFi calling to work on AT&T. I think I remember all I had to do was to add them and make sure permissions were correct
Here is an IMEI that I saw on another post that may work ..... But I do know that the AT&T system needs to recognize your phone IMEI as an att branded device that has working WiFi calling. So if you aren't business customers it will require a call to customer support.
Possible working IMEI:
Mod edit: Removed
Any Pixel AT&T users that could try this and report back would be greatly appreciated!
Btw, I'm not completely sure which files are needed in the Pixel as compared to the S7 Edge .... I would have a backup available

I obviously could be wrong ...... But I'm 99% sure that what you are saying is not true for AT&T and maybe even other USA carriers!
I KNOW that I'm right for S7 phones and ROMs .... And the problem is so pervasive that they have even been able to get unbranded S8's to obtain WiFi Calling on AT&T or other USA carriers (even though WiFi calling works great on branded S8 phones)
AT&T users a different mechanism to provision WiFi calling than other carriers

You are correct that AT&T does not allow unbranded phones to use those features. It's all BS too. I have great LTE coverage but many times I will go to make a call and have crap service because they have canabalized a lot of the hsdpa towers for LTE. Then the switch back to LTE can take forever. And I don't care what they or anyone says AT&T's hspa+ is no where near as fast
None of this works, as AT&T blocks access to VoLTE on Pixel phones. Denies me the use of Numbersync for my tablet and android wear 2.0 watches. AT&T service techs keep promising to fix it and try to force it to work, but still blocked. It is simply a situation for Google to get the Pixel certified for the AT&T network, which is problematic, as AT&T uses a non-standard protocol for HD Voice that is unique to their network. So, as best I can tell, AT&T has to release the source code, for a price, I presume, to Google to add to the phones and then pay for the certification process with the FCC. Seems a stand-off as long as Google has an "exclusive" arrangement with Verizon. So for me, I'm pissed not to have numbersync for my devices, but unwilling to give up all the advantages of the Pixel phone.
That's why I switched to T-Mobile.
So there is no way to get VoLTE on the Pixel XL with AT&T then?

If AT&T carries the upcoming Pixel 2, is it possible Numbersync would start working on Pixel 1 devices?

I doubt it. They only support advanced features on devices sold by them so it's not as if older Pixels will suddenly be grandfathered in just because they start carrying newer ones.
This annoys me to no end... If I buy a phone from att, do they have to give me an unlock code when the phone is paid off? I really need WiFi calling for a trip I make multiple times a year

Yeah according to a rep I spoke with, the pixel 2 will support Numbersync even though att isn't selling them. There are, however, no plans to change the restriction on the original pixels.
I'm in the same boat but I'm genuinely curious - if I don't need wifi calling - is it really a big deal not having VoLTE? I'm taking in terms of better signal or faster LTE internet speed. Or does VoLTE is just having clearer phone calls? I guess what I'm asking is what other benefits are we losing (on a technical standpoint)

Late response but as far as AT&T goes besides VoLTE what I experienced on my Pixel XL was random issues with group text (MMS) reception from certain individuals from other carriers.
In particular it seemed as though if senders of MMS texts to a group chat that I was participating in sent a text from a carrier like T-Mobile and they were using Samsung devices with VoLTE and enhanced LTE stuff enabled on their end I'd not receive the text. I would instead receive texts from others in the conversation. I could freely text any of the same individuals in a separate standard SMS conversation just fine, and they could send me an MMS text like a photo, but as soon as we were in group MMS I'd lose the ability to receive their texts and no amount of APN changes or combinations of texting apps would fix it.
I can't tell you how many times over the course of the first 5 months of owning my Pixel XL with an AT&T SIM in it I missed out on half the conversation in group MMS. Doing nothing to my phone other than porting number to T-Mobile and putting in my new T-Mobile SIM all of my group MMS issues went away (replaced with ****ty signal LOL but that's a different story). I'm now on Verizon with my XL and am a happy camper, albeit poorer having wasted money jumping around.

HD Calling and Advanced LTE on AT&T

I noticed that when I make a call, the phone drops from LTE to HSPA or whatever their 3G band is called. I have an LTE SIM in there that had HD calling working on my Essential, Pixel2 XL, iPhone 8+, OP3, etc...
I was getting HD calling on all of those devices, and I did call AT&T support and had them add my IMEI to the line, so it should be working. Is there something that I have to do to enable it on the phone?
My concern is that if I am tethering while on a conf call, I won't get LTE and that's a problem.
Thoughts?
U had it on ur op3, I thought att did not allow volte on non att phones, I was never able to get it on my op3
I thought that I did, and I did on my Essential. Damn it, this sucks... Might have to go back to the Essential. Not having voice and data at the same time in 2018 blows... I am within the return window, although because of the credit card breach, the card they would need to refund to, has been canceled... What a cluster...
Yeah, ran through all sorts of hoops with several customer service reps. They say that VoLTE is enabled and provisioned properly to this SIM and IMEI, but I can't get it to work and it doesn't even show up as an option to enable it in any of the phone's menus... So either AT&T won't allow this BYOD device to have simlutanous voice and data on LTE, or maybe something in the beta isn't giving me the option.
Is anyone running the stock non beta OOS and getting VoLTE to work on AT&T?
I also gave them an IMEI from one of my other phones, an AT&T branded Note 5 that I own, and told them to put that one in and see if it worked, because that would tell me whether it is the phone itself not able to do it, or a provisioning thing on AT&T's end... That didn't work either...
I then went back to my Essential and had them enter that IMEI and it didn't work either...
I guess if I want wifi calling and voice and data at the same time, I have to pay a ton of money for an AT&T phone... Kinda bummed...
I talked to their support and put the SIM back in my Essential, and it fired right up and has VoLTE and doesn't drop to H+ when I make a call. Same SIM, I didn't even call to give them the IMEI. So something isn't supported on the OP5T.
Which sucks, because between the two phones, I really prefer the 5T. Oh well, I guess it wasn't meant to be... That's the downside of buying unlocked phones, you may miss out on some of the key features that you want on the carrier side...
Which ROM are you on?
Did you turn on VoLTE in settings if you are in stock OOS? If not you can try a custom ROM like Liquid Remix that have VoLTE working
Stock rom. If I have to install a custom rom to get the phone to work, not worth it. I will just return it and get my money back
AT&T only enables VoLTE and LTE+ on provisioned devices and supported, usually BYOD especially for a non-listed device does NOT apply. I was on AT&T when I got my 5T, tried my sim from iPhone 6S and a brand new sim I got at the store that I was assured would have VoLTE capability, but nothing. Not even wifi calling would work on my 5T. No options in Settings either to toggle it. They want you to buy the device from them is why they do this on unlocked phones.
I switched to T-Mobile and I had VoLTE, LTE+, and VoWiFi all on first boot with T-Mobile sim, with all of them listed in Settings on the same device with same software version as I was when on AT&T's network.
It's simply just a case of AT&T not supporting the device. Typically only carrier-sold phones for AT&T will have those capabilities, if you look it up you'll see many people say the same. Personally I'm glad I switched to T-Mobile because they don't lock down all of those features to try to get me to buy a phone from the carrier like AT&T did/does. I'd never go back to them at this point. Sorry but if staying on AT&T is the only option for you I'd look into how you could go about returning the phone to OnePlus and getting something AT&T-approved.

I have an ATT sim from my company originally meant for an iPhone. VoLTE did not work on a google pixel cause the plan was not compatible. And since it is not my plan I can't make changes. I ordered the Oneplus to see if I could get it to work. And on a Stock ROM it will not work without Root and the Magisk Module to enable VoLTE. It will work on Custom ROMS such as Omni and Phoenix, both of with work for me with no issues.
In the end I returned the OP5T for a refund, and am back to using my Essential. While that is a non-AT&T phone that I bought right from Essential, it does support VoLTE out of the box, no issues. I don't get Wifi Calling, but I get HD Calling, works with my tethering plan, etc... Not sure why the Essential works but the OP5T doesn't, and it sucks because I liked the OP5T more... but it is what it is...

It works on ATT, but the issue is that it doesn't do HD Calling, Wifi Calling, etc...
Make a phone call and while you are on the phone, you lose LTE and it drops to HSPA(3G)...
It's not a phone limitation, it's that AT&T won't allow it to have those features on their network. That is the ONLY reason I sent the phone back. Hopefully they address it with the OP6 and get in "approved" for AT&T and I can sell my iPhone 8+ and come back to Android...

Sorry, but this will never happen in the foreseeable future.
AT&T purposely does this to all BYOD, so the OP6 is not going to change anything. They only offer these options for phones you purchase directly through them online or in an AT&T store.

Not entirely true. The Pixels you buy straight from Google, work. The Essential that I had, worked fine. There are phones that work just fine that you don't have to purchase through AT&T.

How did you get it working? I didn't want to root it and install a custom ROM, which I believe was the only way to get it working.
I tried using an IMEI from one of my other phones that I know worked, etc... Nothing worked.
You guys know that even if you show the switches and turn them on, that the LTE data doesn't work right? It's just showing the options and you can turn them on. I even have my OP5t added to my account as an ATT LG G6 and it doesn't work. Unless there is some agreement, like with the Essential Phone or Google's only official phone, you're out of luck.

Exactly, that's what I was getting at. I talked to ATT several times, tried different IMEI's and nothing worked. Regardless of what the options in the menu claim, it doesn't work. If you are just using your phone it will say LTE. But when you make a call, as soon as it connects, it switches to 3G or HSPA+... It won't do phone calls and LTE data at the same time.
If it did, I would have kept the phone. But that's a pretty big feature to have to live without for me. That and HD calling, Wifi Calling, etc...
I wish that OnePlus would do whatever they need to do to get the phone "certified" for ATT, but I don't see that happening...

Yea, it's a pretty crappy situation. I came from a Moto x Pure to the OP5 and then to the OP5t and it was a big disappointment when I was stuck without LTE on calls. I had the Moto x on Verizon though. I really don't get why they restrict BYOD phones at all considering that if people use MORE data, they are likely to bump up their plans to the next tier. I kinda don't get the rationale. Anyway, it is what it is. I love my OP5t and hope to keep this phone for a while, unlike many past phones. But I live in a city, so rarely have issues here.

Wifi Calling on ATT in US

I'm in the US on ATT. I know ATT support Wifi Calling, but I think only on their carrier branded phones. Is there any way to enable Wifi Calling on the 5T? Would calling ATT to get them to enable it on my line work?
In my experience WiFi calling in the US on these phones is pretty much limited to T-Mobile. I had them for a bit and both that and VoLTE were immediately triggered in the phone settings. I asked an AT&T rep in the store about these features and their response was "if the phone's compatible then it should work". When I pressed the issue it sounded like the IMEI is what AT&T uses to determine if it's "compatible" so we're out of luck. I haven't tried calling in though.

I think what you're describing sounds correct for the US. Too bad they do this to lock out that feature to try to make you buy their carrier branded phones.

Samsung GalaxyNote 10+ and AT&T problems only 3G phone calls and data

we have 3 Note 10+ my son ordered his the day of the preorder release. he has the 256 version and my wife and i got the 512 version.
Upon my wife and I getting the phones we replaced the sim chips with new ones from AT&T instead of removing the ones in our Pixel 3xl. I noticed that AT&T Visual voice mail wasn't there but after loging into our voice mail account it downloaded a different visual voice mail program.
however we are having signal problems, I noticed that we didn't Get Voice over WIFI, Advanced Messaging, Volte etc. I called into support 611 and explained and they said that they would re-register our phones to turn them off for a few min and back on and should be ok.
That didn't' accomplish anything. I talked with an engineer that I know that works for AT&T and he said that my son's phone is provisioned for VOLTE with torch i think but not in the account screen. My wife and my devices are not provisioned for VOLTE HOWEVER NONE of our phones are connecting for voice or data to 4G LTE only 3G. He didn't know why but would check further.
after complaining to OOP with Samsung and being within the return window they said that we could order from them the branded AT&T phones and return our unlocked phones.
I realize that we will get stuck with the bloatware, but if we are getting 4G LTE VOLTE etc. maybe that is what should be done.
If we do that can we still get them unlocked and what do we loose by doing this? I appreciate the work everyone is doing here and I think hopefully I can get an honest answer vs everyone pointing the finger at everyone else.
My big concerns are:
If I keep these what do we loose?
How bad is the bloat ware?
If we change to T Mobile or others later can we, or if we travel, get AT&T to unlock the phones
If I keep these phones and flash the AT&T files will we:
Then get access to the programs and services we don't have now?
Get over the air updates as they are released?
I would highly appreciate any advice
Thank you for everyone's help in advance
I was getting horrible battery usage on my At&t branded Note 10+. What I did was flash the U1 unlocked firmware, set things up, made a few calls, sent a few text so things provisioned to At&t. I then flashed At&t csc with odin and this gave me 4GLte..wifi calling..video calling..advanced messaging..and volte

but your phone was branded AT&T right so theIMEI number is active in their system
I had the same issue - thankfully, I was able to test a friend's SIM card from AT&T and his worked! I saw an obscure reference (see below) to it being an issue with older SIM cards. I'm heading to AT&T store to replace mine tonight.
