Question for AT&T LTE users

So I get LTE but as soon as I get on a call signal goes to H and I cant use data/apps while on the call. Am I using the wrong APN settings, or wrong radio maybe? Any settings help would be great, or if you can confirm also. Thanks.

Mine nexus 6 did same thing. I'm not sure that the data still work or not but everytime I on call I see LTE Icon change to H like you said

It's one of 2 things.
Either VoLTE is not turned on on your device
Or ATT does not support VoLTE in your area.
First one is fixable. Second one is not.

AT&T doesn't support VoLTE on any phones that aren't sold by them.

Then that would explain that I would think

LTE is data only, so when u go on a voice call it will got to hsdpa or 3g bc that is voice and data, so it is normal

Please don't spread information that's no longer the 100% truth. AT&T, Verizon, and (for a while now) T-Mobile offer calling over their LTE network, dubbed VoLTE (Voice over LTE). It allows voice packets to travel over the LTE network instead of legacy/3G and older networks.
The way the standard it set up, devices made more recently have software and hardware support for it, but as carriers have certification processes for their network, not all devices work cross-carrier. Most notably, iPhones (bleh) work cross-carrier because of the way their network configuration is provisioned (device identifies what network it's on, and downloads carrier configuration for that particular network). Some Android devices work cross-carrier (Nexus 6P and 5X), but the manufacturers of Android devices designing unlocked devices for some reason aren't certifying on AT&T, maybe because of cost or complexity.
Therefore, there are 3 main reasons VoLTE won't work on a device:
1) Not in a VoLTE area
2) VoLTE not enabled (this could encompass the option simply being disabled per the user)
3) VoLTE being restricted (AT&T restricting access because the device isn't certified, and/or the device not being capable)

So how do you enable on the OP3 with AT&T?

You can't, only thing that would remotely make it work is if your imei was set up as a HDVoice supported phone in AT&T's system (s6, s7, note 5, note 7, iphone, etc). Though that likely won't work either since it'll try to provision the VoLTE and fail and yea.

AT&T does not use "Standard" VoLTE, so even if the phone supports it (like the OP3 does) and they were to allow the IMEI, it still wouldn't work. Phones have to have specific code from AT&T to do their HDVoice (according to their own customer service postings in their forums)

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

Not getting VoLTE on T-mobile on XT1710-06 version

Is or has anyone else been able to get VoLTE working on T-Mobile US on this model specifically? LTE and WiFi Calling work in general, but the "Enhanced 4G LTE Mode" toggle isn't there to allow VoLTE. The model has the same number of bands as the XT1710-01 model, but is on the RETLA channel, by the way.

Hi, actually I was having similar issues. VoLTE, seems to be different but is based on your Carrier mostly. If you call someone from a different carrier it may not be enabled. I'm with AT&T, whenever I call someone with AT&T and we are both with good 4g LTE, in the call, changes the status to HD. But, just with AT&T. At least that's how it Works for me. We should wait someone to confirm is this is how other carries behave.

Apologies for the late reply. Definitely no VoLTE or HD voice between me and other T-Mobile users. No matter what I tried it just never came up. If anyone's considering using this specific variant of the phone in the US, I'd be aware of the limits beforehand.

-06 is a North American dual sim variant, correct?
Are both SIM cards on t-mobile?
Could one use SIMS from different carriers?

-06 is a North American dual sim variant, correct. Updates should go through ATT Mex, I believe. And yes, you can use sims from other carriers. I used one sim card when I tried it and only utilized one of the sim slots as a result. T-Mo VoLTE just doesn't seem to have been certified for that variant.

So T-Mobile WIFI calling works on this variant of the Z2 Play? If so that is good to know especially when traveling overseas even if some other advanced features don't work.

I have an XT1710-06 retla device and I can confirm that wifi calling with T-mobile does *NOT* work on my device. There is a setting to enable wifi calling, but it never seems to connect and all calls still go over mobile. This is 100% testable if I for instance go into a deep basement that has wifi but no cellular signal -- I can browse the internet but cannot make phone calls or SMS, even though I have wifi calling turned on.
This is probably related to why VoLTE doesn't work either.
Also (as mentioned in another thread) still no updates for it past February 7.1.1 update. No later security updates and no Oreo updates.

Hi,
I'm super curious how did you get your Z2 Play to have VoLTE. I 've tried everything - new sim, IMEI of ATT branded phone, activated SIM on ATT phone, etc. , to no avail. I'm so frustrated and about to get another phone, because my HSPA signal is much weaker than LTE where I'm at and constantly have missed (straight to voicemail) or dropped calls. Please, let me know how did you get it to work.
Thanks

Maybe the problem is VolTE itself. As I tested. Unless both phones are with the same carrier and working good over 4G (good signal area) you can't get it working. At least in where I live that was true for a friend's phone and mine. So VolTE was good, until signal dropped hard. But impossible to work with other carriers.
Even it was good under Lineage OS and tested with Toxyc OS, but I saw the main thing is that 4G LTE should be firstly working fine. And same for anyone you call. Otherwise call will be normal. And for 4G LTE it depends on area support too.
Sorry for late reply

Same phone (XT1710-06 retla, rooted stock ROM on Oreo), and wifi calling on Tmobile also doesn't work for me. I can enable it in Settings, but I cannot send SMS or make calls over wifi with no cell service. After a while (a few hours) I get a Moto Settings notification that it can't enable Wifi calling, with a message underneath that says "Enabling." I can't dismiss the notification, only snooze it for up to 2 hours, and after I disable wifi calling it does eventually go away after a couple days.

Your problem is because none of the XT1710 variations have the 600MHz Band 71. It is the most recently added band and very few phones currently out there support it yet. As far as the HD voice issues mentioned...both people on the call have to be using a Volte supported phone and then HD automatically activates.

Wi-Fi calling on pixel 2 XL in Europe

I have a Pixel 2 XL in Android 10 build QQ1A.191205.008 and there is no option to enable Wi-Fi calling.
I know that the phone is capable of Wi-Fi calling but for some reason that option does not exist in system settings
I am in Greece and in Vodafone network which is providing Wi-Fi calling
And help would be appreciated.

Is the device itself on Vodafone, or are you using a different carrier? Your carrier has to support it for the option to become available, and even if the carrier does there is a possibility the carrier's network doesn't recognize the device as being capable of the feature, especially if it was bought from Google.

Thanks for your reply.
Yes it was bought in the USA.
The ROM does not belong to a certain carrier
It's the official universal room
I haven't root the phone.
It gets all the updates over the air.
A standard factory set phone.
I conducted Vodafone and apparently they don't support yet Android 10 ! Although they state that the Samsung s8 and newer and the iPhones are supported (they don't mention any Google phone)
Anyway I thought that the option to enable Wi-Fi calling should be available on the system settings of the phone.

ROM is irrelevant as this is a carrier thing. As you found out the carrier you're using doesn't yet support the feature. Thus you will have to do without. The P2XL won't have the option to enable WiFi calling until the carrier supports it. Example: my carrier (Straight Talk) doesn't support WiFi calling and I do not have the option in my settings.

Okay crystal clear
Thanks a lot

Question Verizon Wi-Fi Calling?

I have the Global LE2125 version of this device. Many people with different carriers have no issues getting Wi-Fi Calling working or even with different models.
My question is has anyone gotten Wi-Fi calling with Verizon to be successful before with this device? If so how? I need it for work as there is no cell service in that area so I can receive calls or texts there. Please let me know what everyone's experience has been!

I have, the only thing they really say is for me to check settings and if the options not there change my software version. Which is a stupid answer because many tech support teams don't understand the concept of Bootloader unlocks and etc

Is your LE2125 original with stock firmware. No changes or flashing has been done?
