VoLTE on AT&T

Does this work? Does anyone know how to enable it?

Great thread. I wonder if we can enable it because it does not work with any custom roms

It's been confirmed working on the pure nexus ROM. Check the development thread

It has not been confirmed working on att. I follow that thread closely. It's is working on Verizon and Tmobile.
I am running pure nexus with att and no volte

My apologies. I must've read it wrong then

Stu, do you have a VoLTE enabled SIM in your 5X? You have to have an account in the HSS and TAS to get an IMS registration...

I really don't know. Is volte working for you on att and the nexus 5? I don't think it can work but I hope I am wrong

Did you just pull the SIM from an existing phone? If so, was it a VoLTE phone? AT&T will only provision the SIM/Account for VoLTE if you have an approved device.
And no, I have not gotten my 5X to do VoLTE yet....working on it.

My friend just got Nexus 6P + new AT&T sim card. We made couple of calls and there is no VoLTE option in the cellular settings, as I have with my 5X on T-Mobile.

Remember that any VoLTE network is *completely* different than the existing CDMA/GSM/UMTS networks that the providers have. VoLTE utilizes an IMS or USP core that the phone has to register on to get VoLTE calls to work. The SIM information has to be defined within this IMS core, otherwise you will only get legacy services.
AT&T will currently only define a SIM for VoLTE is you have a certified device that they sell. But I already have VoLTE phones and am trying to use their SIMs without success. I think the 5X software may not be allowing the IMS registration. If you are on T-Mob I would call them up and see if they will provision your SIM for IMS....they don't seem to care about what phone you use.

How to enable VoLTE on Pixel?

Hi guys.
Let me elaborate my question.
1. I am totally aware that VoLTE on Android at the moment generally requires the handset to be from the carrier, or from the same region as the carrier for it to have the correct VoLTE (and VoWIFI) settings.
2. I am also totally aware that since Android 6.0, there actually has been a provision to allow carriers to send carrier settings to the user. I also know that this isnt being widely used.
After my ownership of my Pixel XL, I moved to a HTC U11, which I have flashed a custom ROM. This custom ROM managed to have the carrier settings for VoLTE for my carrier baked in.
I am keen on getting a Pixel XL2, so Im keen to see what the Pixel community is doing to enable VoLTE on networks that arent stocking the Pixel or Pixel XL.
Here in Australia, both generations of the pixel seem like they will be Telstra exclusives. and I am not inclined to go on their network!
Thanks for any assistance!

I use it with T-Mobile, only Verizon stocks it in the States. Volte works fine for me. Nothing i needed to do other than to setup the phone with the Sim card in the device.

Same here, got it with my T-Mobile SIM card.

This worked for me. Go to dialer and dial
*#*#4636#*#*
Phone Information
Turn on VoLTE
Turn on Video Calling
Turn on Wi-Fi Calling
Exit

I'm on Oreo 8.1 on my P2 XL, looks like it's already enabled. I'm on AT&T.

Change carrier. AFAIK you'll never get enhanced LTE services using a non-AT&T branded phone on their network. Once I switched my pixel xl to T-Mobile things like that and wifi calling worked fine.

My condolences to your Pixel XL 2. I was in a Verizon store the other day just to check out PXL2. The blue tint when turning the phone horizontally - horrific. Also, barely faster than my Pixel XL, even if you care for that kind of thing (speed.)

Same problem in Argentina, Pixel is NOT SOLD here so.... out of luck, but I tried this (already knew of the menu) and all my options are blacked out -can't enable any of them-, advice?????
Thanks.

If you can get root on your phone, flash magisk and there is a module in there to install that can enable VoLte and Wifi calling, worked for me on AT&T.

the module only changes the settings to allow for toggling but does not provide needed ims libraries.

I had to toggle VoLTE off then on, restart. It's working for me now

"Turn on Video Calling"
Option is disabled, couldn't turn on

Depends if you're on Verizon or straight talk or what. I'm on straight talk and they don't offer VOLTE even though they use Verizon towers.

Using *#*#4636#*#*, the VoLTE provisioned option is greyd out. Anyone has a solution for this?

It means your operator is not offering VoLTE, or, as in my case, Pixel XL is not approved by the operator. I have VoLTE on my SIM enabled and working with operator approved devices but network rejects Pixel as not compatible one.

Operator offers VoLTE and it doesn't filter IMEI like in some cases. Other not approved devices (e.g xiaomi, oneplus) managed to enable volte via shortcuts. I am asking for a similar workaround. --thanks

Of you're on Straight Talk you're SOL. They don't offer it even if you're using a Verizon SIM

If you had geryed provisioning options you need to use magisks voenabler. a did it right now on december pie update. Now I have all enabled. Just waiting for operator to enable volte for my number. I wonder it will active.

Hi, my carrier does support VoLTE but the Pixel is not on its whitelist.
When dialing *#*#4636#*#* and going into phone info, the switches for "VoLTE Provisioned" is off and greyed out, but at the top of this screen I see "Voice Network Type: LTE". Does that mean I am getting VoLTE? I cannot see any other sign or symbol when calling. (I know some devices have a VoLTE symbol either in the status bar or during a call)

Where's VoLTE and VoWIFI controls on Cricket v35?

I got a v35 from Cricket, and when I plugged a Mint Mobile SIM into it, the phone not only worked (it's different network), but also displayed an indicator which said that VoWIFI will be used for phone calls. Once I plugged a Cricket SIM, I'm no longer seeing this icon. Also, I upgraded to latest firmware (PKQ1.181105.001), and I'm not able to even locate the setting that enables VoWIFI anymore.
Anybody knows what's going on here?
SKU: DLGN4125
Model: LM-V350ULM

Does Cricket support VoWIFI and if it does, is it enabled/provisioned on your Cricket account?

Enable VoLTE Redmi Note 8T Stock MIUI 11 with TMobile USA

Purchased a Redmi Note 8T phone to replace my mother's aging LG feature phone, specifically due to TMobile USA dropping support for phones without VoLTE in January 2021. Followed the steps to disable the carrier check *#*#86583#*#* and confirmed that VoLTE option shows enabled on *#*#4636#*#* menu. Also confirmed I'm getting LTE signal and data. In the SIM settings it shows VoLTE enabled but no icon next to signal indicator and doesn't say HD when making calls. IMS status says Not Registered. Any suggestions? Is this because the phone has been on the TMobile network for only a couple hours? Or because TMobile still thinks she's using the LG feature phone which definitely wasn't VoLTE capable?

After much testing and process of elimination we have basically determined that either it's not possible on the US T-Mobile network, or that getting it to work is far beyond my technical capabilities.

Question Unlock version from Google on AT&T in the states

I'm wanting to get the Pro in black with 256gb storage but need to know if anyone is using any unlocked version from Google (not carrier branded that had be unlocked) on AT&T network and getting volte with calls. My company pays for my work # and just gives me the SIM to use in my own phone since I don't want an iPhone that they provide. I currently use a Huawei Mate 20 X and have that SIM working along with my personal # that's on T-Mobile (dual sim phone). Unfortunately due to AT&Ts whitelist any calls made/received on that # switches to 3G, this will make my current phone unusable after they shutdown 3G this Feb.
TIA for any info

I have an unlocked 6 pro on att and I think volte is working but don't know how to verify. I know wifi calling is working which was an issue with my previous unlocked phone

Unlocked Pixel 6 Pro user with ATT here. The wifi-calling works perfect, and surprisingly the visual voicemail is enabled. It seems to work just like an ATT-based phone without the bloatware. Odd thing is you cannot change the mobile network. Read somewhere here the ATT disabled this setting for some reason when connected to their network.

HD Voice (AT&T version of VoLTE) works perfectly well, as does WiFi calling, provided of course your account is provisioned for such.

Thanks, good to know. Currently with my Mate 20 X when on a call with the AT&T line the network switches from 4G lte (when not on a call) to 3G (when on a call) then back to 4G lte after the call has ended.

@Vash369 - thanks for sharing your feedback. does your unlocked P6P support dual SIM, e.g., physical sim card and an e-sim?

I'm not who you asked, but I believe all the factory unlocked P6Ps support dual SIM via a discreet SIM card and the built-in e-SIM.

Yep it does. It shows this in Google's spec sheet page. Mind you I'm only using physical SIM. So I don't know if both will work at the same time

Another unlocked/rooted P6P working fine on AT&T here. I just sim swapped from my old phone and it worked right out of the box.
