Is VoLTE available for CMCC? - Nexus 6P Q&A, Help & Troubleshooting

I'm a Nexus 6P user in China, my carrier CMCC provides VoLTE in my city, but I can't find the option on my phone. Is there some ways to turn the VoLTE on?

In India too, a carrier Jio supports VoLTE but 6P didnt push a update to enable it on software side.

I think it may be not hard for Google. Maybe they never care about us, the users in the third world?

Exactly, its been more than 6 months we have been asking Google about this,but they dont even give an actual answer. They provided the same volte update for Pixel devices a month back. Also they care only about US.

It's the lowest frequency cellphone band, so theoretically has the best range...
for t-mo at least, it's their answer for being able to keep a cell phone signal inside of buildings. the lower the MHz, the better it penetrates, and like was said, generally the longer the range too.
If you're not on T-Mobile band 12 is worthless to you.

What exactly is BS? T-Mobile is pushing manufacturers to disable band 12 if they don't have VoLTE due to issues calling 911. Until Motorola decides to add VoLTE on their devices, I doubt you will ever see band 12 enabled on their non T-Mobile branded phones ever again.

You may not buy it, but it is clear T-Mobile is pushing manufacturers to disable it when they don't support VoLTE. I guess it is fun to have grand conspiracy theories but the real reason is clear.

You didn't even give a reason. You just said Motorola is lying. Yet, we know manufacturers of unlocked phones are disabling band 12 when they don't support VoLTE. Clearly, T-Mobile is pushing them to do it as they gain nothing by disabling it for any other reason. I'm not going to believe your random conspiracy theory over common sense.

Just read the 6p supposedly has tmo wifi calling out of the box. A developer got his hands on a leaked system image and its there.
I hope they bypass carriers in the US and go the Motorola route. Sell them on Amazon, Best Buy and Google Play only.
Hoping they offer the 6P with Jump On Demand on T-Mobile so I can just upgrade to it from my G4 without a hassle.

Curious.... What are people going to do if they get the phone on TMobile and it has no volte? Essential won't tell us so who knows
I thought this was already stated that it would work with all carriers including Tmobile
Yes but that doesn't mean it will support volte, HD or evs
I’m pretty sure it was asked directly if the phone would work with those features and they said if the service supports it then it will work as intended. The only questionable thing was some sprint uses which I forget what it was.
well, my Mi Note 2 supports VoLTE so I have no reason to think that this device will not work accordingly.

For wi-fi calling I just went to an area with wi-fi but no cell signal and confirmed I was able to make a call with it turned on. For VoLTE I just checked that the data didn't drop to 3G or EDGE when I made a call. And for HD Voice I just called another T-Mobile phone and it'll say "HD" next to the call timer if it's an HD Voice call.
Wifi calling turned on today on my phone after not working the past 3 days.

Wifi Calling on At&t Google Pixel 2 XL

Opened the Settings app earlier and there was a suggestion at the top to turn on Wifi calling. I'm on At&t and November update.
How did you get this to work? I've been trying to days to enable this option. I pushed "adb shell settings put global wfc_ims_enabled1" but to no avail has it worked.
I am on AT&T and have tried this with both a Google Pixel XL 2 from Google and Verizon. If you could give me any details of what your setup is like so I can try to enable this I'd dearly appreciate it!

+1 how? Very curious.
a screenshot showing the actual call going over wifi is needed.
unless ATT changed their mind in the last week, WiFi calling isnt available for the Pixel 2/XL, even if the option is enabled, the account has to be provisioned, and the phone needs the proper IMS profile, ATT to this date has refused to allow it.
This is the first I've seen the option even appear. Will test some calls and report back.

Looks like it isn't up and rolling yet, but the fact that the option appears has me hopeful. At&t still doesn't say that it supports VoLTE on P2XL, but we have that working, so perhaps Wi-Fi calling is coming soon.

Here's hoping. My apartment is on the bottom floor so reception is very spotty. What has been weird though is that if I start a call when I have reception and move to a spot in my apartment where there is no cell service, the call persists. So part of me thinks me enabling Wifi Calling from ADB may have done something?

Because idiots around the US have no idea what they're talking about then they say "VoLTE on AT&T only works with AT&T-branded Android phones or iPhones". As long as a manufacturer certifies their device with AT&T, and configure their devices with the proper IMS profile for AT&T's network, VoLTE will work. Google (HTC/LG) certified the Pixel 2 / 2 XL with AT&T for VoLTE and RCS, both of which work if all criteria are met (proper SIM card, IMEI updated in billing system, options turned on), and right now, 8.1 DP1/DP2 are needed to use VoLTE on AT&T's network, as the modem/IMS configuration was updated on the phone to support it.

VoLTE is enabled in Android 8.1 for AT&T. I just flashed the final factory image and it does indeed work. You do have to verify that your sim card is properly provisioned for VoLTE. As for the WiFi calling portion of this conversation, I still cannot access the "Wi-Fi calling" setting within "Mobile network settings."
I am on 8.1 on AT&T but the unlock version of the phone... I don't ave the VoLTE

Check to make sure your sim card supports it. If it does you'll wanna call att and have a technician make sure your account is provisioned properly. Also you'll need to make sure they have the IMEI of your phone.

I just bought a Verizon Pixel 2 XL and Volte doesn't work. I'm on 8.1.0 February security patch. I thought that the Verizon Pixel was exactly the same as the Google Store version, other than the locked bootloader. Does anyone know how to get this working? I've already called At&t twice, and they say it should be working.

How about if you're just on 4G? Turn off 5G. When I'm on a call using 4G LTE and surf web it stays on LTE and doesn't drop.down to say 4G or in the uk it'll probably be 2G or 3G if I was originally on 4G.

Comical. Mines the other way around. Shows volte in status bar for both sims but that menu shows volte off. However disabling one sim then shows those options volte enabled via that menu posted. Rather confusing so to speak. However in practice volte is working.
Edit worked it out. For me, if I select voice call as "ask .." then those sliders in the 4636 menu are off.
