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.

Wifi calling

So is it possible to enable wifi calling and/or VoLte on stock 8.1 rooted or any firmware of the pixel without being on Verizon? I am on AT&T so just wondering if there is a mod or something I can do to enable it.

Magisk has a module that can do that; VoEnabler .... this module will enable access to the features in the pixel, in Dialer, settings, etc. * but that doesn't mean you can actually use them;
First, check that your carrier/service actually supports the feature .... You can check with a secret code though; in Dialer;
*#*#4636#*#*
Then navigate to "Phone Information"... from there scroll down;
you should see the stuff for VOLTE, Wifi Calling, Video Calling, etc. If it's enabled then you may be good to go..
but if your carrier doesn't support it - enabling it via VoEnabler will do nothing to change that.
Also, I don't know about the US, but in Canada - some carriers (under some plans) do charge extra for this stuff.

It is all carrier dependant, i got my XL from Verizon and I'm on TMO and wifi calling and volte is working but I don't think att supports the pixels for volte and wifi calling

Sort of this. Basically AT&T will not support VoLTE or WiFi calling on any unbranded unlocked devices brought onto their network. Never worked on my T-Mobile Note 4 nor my Google purchased Pixel XL. I was a long time subscriber to their service but once my dependency on MMS messaging increased I had no choice but to switch to another carrier. I wound up on Verizon after a brief time with T-Mobile. Both support full functionality of these devices.

Before installing magisk I dialed that number and they were all greyed out, I installed magisk installed the module and now VoLte and Wifi calling are both enabled in that menu and in the settings menu. I tested wifi calling and it worked. So maybe just need the module installed and it will work. That's what worked for me.

Cool. glad to hear my advice helped... but also using the secret code in the Dialer would've verified if your carrier supports it on their network, beforehand; that's why I posted in that step...
also, just as a reminder; I'd make sure that there aren't any hidden fees associated with using those features, I don't know much about US carriers; aside from that they are (generally) against Net Neutrality.... But I know with my particular carrier, in Canada; If i wasn't using the plan that I am on; they would be charging me extra - and it would add up quick... so best to double check, maybe.

I came to this phone from a s7 edge that had VoLTe and Wifi calling on it never got charged for anything, would it be different with a non carrier phone?

I have no idea: I live in Canada and have never dealt with US carriers ~ that's something that you will need to verify on your own. Some may allow it; some may not... you guys do things quite a bit different south of the border, so I just don't know....
You should be able to find that out in the support/QA area of your Carrier's website ~ if not there, you can ask them directly.
but yeah, obviously, if it was working on your S7 - then your network supports it....

Hello, I am on Vodafone UK, recently my area is getting poor 4G coverage so the vodafone tech guy asked me to shift on wifi calling inside the house. He enabled it from carrier perpective but I have to enable it on handset as well. I struggled to find the option. Now using the secret code above I can see I have wifi calling option greyed out. btw, I am on stock android 8.1. What is the best and least intrusive way to get the wifi calling working on my handset.
I am not a developer but have experience with root on previous devices. If I have to install Magisk( is there a non-root option?) what module etc I need to install to get this working please..

Flash magisk and get the module called VoEnabler just sear h VoLte in the search bar it should pop up then after it installs restart phone and you should have the options.

Hi Praveenjohri - did you get this to work?
I too have a Pixel XL and on Vodafone UK; again the wifi calling option is greyed out.
Any layman guides as to how to Flash magisk and go about enabling this? Thanks in advance

Samsung S9 Wifi Calling ROM Question

I have a new Sprint unlocked Samsung S9 SM-G960U1 and am trying to get the wifi-calling to work with Cricket Wireless. Currently the wifi calling option doesn't even show up. I was wondering if flashing an after market ROM would enable me to access the wifi-calling feature. Cricket supports wifi-calling, but only on Android devices purchased from Cricket (a note I didn't see before I bought the phone). If there is please letr me know which ROM would help me achieve this.
Thanks

Wifi calling and volte do not work on byod there is no roms for this phone. You can root but I can assure you this isnt gonna work either. All you can do is buy a cricket wifi calling enabled device

incorrect. it merely needs to be provisioned by cricket on the back end by someone who isnt the typical moron with a headset. the reason byod devices have trouble is due to the IMEI not being listed in their system and it takes a ticket to be sent to the telephony dept and have it added. They dont like doing it, but they will when pushed. Unlocked A8 and A6 on cricket both had wifi calling and VoLTE after provisioning was complete.
you also have to have the right csc on the phone.

I have a method with imei from a good cricket wifi calling phone. And have it working. But I have to give them another imei once I have it provisioned. Once their system updates with my imei I lose my wifi calling. But after provisioning I give them my actual cricket devices imei and tell them the system is still showing my byod imei they need to change it back to the other device. It works. But imei in their system is wrong.
Not imei switching or anything like that. I physically own a stylo 5 from cricket I dont use. So they think I'm on that and not my g9650. So I know it's possible just a real pain

New Firmware SEA

Hi
New Firmware got released today.
58.0.A.3.170

No new feature

Nothing that I noticed. IMS not registered. Volte enabled in settings, unavailable in service menu, available with my provider. Very frustrating.

It is Sept. security patch.

Where are you, and with which carrier? In the US, with US market phone, AT&T does not register this phone with IMS, but T-Mobile does. On T-Mobile this phone has VoLTE but not Wi-Fi Calling.

I really hope they enable WiFi Calling with an update. The phone is perfectly capable of it, since it's the standard Android IWLAN implementation.
RIght now, I'm using the DIGITS app to have WiFi Calling and Texting as a workaround but it's cumbersome.

WIFI calling and VoLTE work with Google FI. I had ATT for 15 yrs and switched. Sick of nothing working unless you have a ATT phone

New firmware 3.224

VoLTE/Wifi

Question about the impending doom of custom roms. I'm with T-Mobile and don't want to switch. So are texts included in this as well, or are only voice calls affected?

You are talking about this:
All U.S. V30/V3O+/V30S will need stock firmware, not LOS-based custom ROMs. When?
The first post is the most relevant. By page 3 the discussion had digressed into other areas.
At first, I thought only voice calls should be affected. (But... don't you need voice calls? Or do you have something like Google Voice? I have Google Voice but in the U.S. I still piggyback on my carrier's assigned phone number.)
(backstory, skip over this if you already know it)
4G LTE started out as "data only". Initially carriers had you temporarily dropping down to 3G (HSPA or CDMA) for voice calls until VoLTE (Voice Over LTE) was perfected.
But for V30 LOS custom ROMs -- which don't have VoLTE -- users still needed this temporary 3G access during phone calls. After the phone call is over, then you jump back to LTE (data only).
Now that 5G is being rolled out, U.S. carriers are killing off 3G to use those resources for 5G. AT&T is keeping 3G HSPA until February 2021, but initially it was reported Verizon and T-Mobile (Sprint) -- and their MVNOs -- are ending 3G in the next couple months. Verizon by January 1, 2020 and T-mobile allegedly in "January 2020" but they have set a specific day of the month that I've seen.
HOWEVER. HOWEVER...
T-Mobile may not be abruptly ending 3G HSPA in January 2021.
Instead T-Mobile says if your phone is not VoLTE capable by sometime in January 2021 it will be shut out of their network. This is not saying they are shutting down 3G HSPA in January 2021 -- just forcing all phones on T-mobile network to be VoLTE capable for WHEN they do shut down.
Hmmmm...
This potentially means you could still use custom ROMs a while longer if you somehow pass their VoLTE capable test? Because 3G HSPA may still be available for a while longer.
On the other hand if you do NOT pass their test, you can't use their network for texting either!
_____________
(Go to article below to see complete instructions and screenshots.)
How to find out if your T-Mobile phone has VoLTE support
T-Mobile will shut out all incompatible devices next year (2021).
Check the Settings app
If your phone is already activated on T-Mobile, you can check in your phone's settings if VoLTE is being used. Open the Settings app on your phone and go to the 'About phone' menu, then tap on 'SIM Status'. If you can't find it, try pressing the search button in the app and typing SIM.
Once you find the SIM Status option, tap it, and a popup should appear. If the voice network type is listed as LTE, you're good to go.
If your Settings app doesn't have that menu for whatever reason, try dialing *#*#4636#*#* in your Phone app. This will take you to a hidden diagnostics menu. Select 'Phone information,' then check if LTE is listed under Voice Network Type.

Ok, I had read some of this before, but not all. My phone passes those VoLTE capable tests. So does that mean that my phone is capable, but still not using VoLTE because it's on a custom rom? But that since it's capable, I'll still be able to use 3g network until 2021? And that once I lose voice, I lose texting as well?

If your carrier completely switches to 4G network then you can't use even text messages without Volte
Though using Google messages with RCS may allow you to get and send text messages with internet connectivity.

My best guess, but I'm not T-Mobile:
If your phone passes those tests then it probably won't be locked out of the T-Mobile network in January 2021. If so, then you will still be able to use LOS custom ROM for voice calls, for as long as T-Mobile keeps 3G towers running.
When they do shut off 3G -- may happen gradually, not all at once -- you will not be able to make phone calls on custom ROM without VoLTE, but should still be able to text.
Texts are data, and data-only LTE signal should still allow texting.
