Mine isn't working either and I'm in a live VOLTE market and it's worked on other devices.

Mine works fine

Mine works some days and doesn't work some days. It's annoying.

Is it possible the other person does not have volte? I remember only able to use that when i was calling other T-Mobile users.

Correct! In order for volte to work BOTH phones must be enabled, and in a volte market.

Ditto. Read some papers on how VoLTE works and called up T-Mo to confirm, they said because of how the connections between the phones are established, both phones must have LTE and live in a VoLTE market. VoLTE actually uses a higher quality coded than HSPA+ if I recall so the other person has to have the ability to receive and decode properly.

Before i did factory reset,i could not get volte, but now i have volte( they show hd in contacts) after factory resetting the phone. Two things i hate about this phone are battery life and chrome browser lagging. And now i just found out a new issue is touch screen sensitivity. It is less responsive than my old galaxy s4.

Has this been recently changed? I had an Xperia z3 and any time i was on lte, my calls were routed volte. I'm 100% positive this is the case, my mother has an M8 without volte, my Xperia still used volte when calling her.

It's not new. Are you sure you had VoLTE? The basic requirement of VoLTE requires both users to have support of this.

Positive, it was only "HD" if i called another volte device, but it was always used on my end. Dead give away was that m phone stayed connected to lte while in a call, if i turned off volte in settings it would drop down to hspa while in call. Also, there are areas around me that seem to only have edge and lte, no hspa. In these areas it would drop to edge when making a call with volte disabled, with volte enabled it stayed on lte.

HD voice is when both devices are connected to at least HSPA when you are connected to TMO's network as far as I'm aware. There are some old articles that you may find if you do a google search, since HD voice is still a rather new concept to TMO.

I know, its a little odd, when volte was not enabled it would display the hd icon whenever i called another hd voice enabled phone. However, when i had volte on, it would only display it when calling another volte device. I know my phone was always using volte though because it would stay connected to lte while in a call with it enabled.

So if you're in a Band 12-only area, and VoLTE is literally the only way for you to make a voice call, you can only call other VoLTE-enabled devices? I find that a bit hard to believe.

Wifi Calling, Verizon Pixel 2XL, using Straight Talk AT&T Sim no option

Hey all, I've been pouring over the forums here and other places trying to find a solution to my issue. I just got a Pixel 2XL the verizon version and I'm using it on Straight Talk with an AT&T sim card. So far so good except I cannot get wifi calling. I'm pure stock, android 9/Pie, no bootloader unlocks/rooting etc. The wifi calling option does not exist in the phone app nor in the settings anywhere. Even when you search for wifi calling, it simply takes you to the network and connections section of settings but wifi calling is no where to be found. I've tried the adb command (the one that apparently used to work on Oreo but not longer does on Pie) and that didn't work (though I didn't expect it to since many people said it no longer works on Pie). I have an Unlocked Note 9 as well and its wifi calling works perfectly fine so does anyone have a way to make this work? Reception at my home is somewhat lacking and I really need wifi calling.
Thanks!

Could you attach a screenshot with the WHOLE section of "Mobile Network", found inside of "Network & Internet" in the Settings -- make sure that you click on the drop down menu next to "Advanced Calling" -- this will help make sure that wifi calling is really missing as well as might point something out that may help with a solution. Moreso, personally, because I can't even imagine what the settings menu looks like missing this...

It might be a long shot but try checking the settings in the Google phone app. There should be a place that says configure IMS calling. I have this setting here and in the network settings. If you have it that's where you can enable wifi calling.

Been there done that. I have no options for setting up IMS calling. I only have SIP options. Also, I have tried the phone dialer trick (where you dial *#*#4636#*#*) and that shows the wifi calling option as a toggle but its greyed out and cannot be enabled. I even tried an adb trick that used to work on the 1st gen pixels, but to no avail.

What happens when you enter your information here?
I'll have to initiate a chat with Straight Talk. Like you I have a Pixel 2 XL with a Straight Talk AT&T SIM. The only difference is that mine is unlocked. I just ran my phone number and the IMEI of the SIM through the linked site and it tells me my device is not compatible. Since I have a BYOP SIM and the IMEI is of the SIM itself, chances are high that the SIM needs replacing with one that includes WiFi calling support.
EDIT: According to the representative I just spoke with, there's no guarantee that changing to a newer AT&T SIM will enable the feature. The only guaranteed method according to tech support is switching to a T-Mobile SIM.

Hey thanks for the help. I tried that link as well (before I posted here; sorry I should have mentioned it) and it said my device is also not compatible. I initiated a chat with them and they told me the same; switch to T-Mobile. I am tempted to do so but the one thing holding me back is my home is already a place I get poor signal and T-mobile's coverage while much improved still isn't as good at AT&T's. I realize that having wifi calling would fix any lingering signal issues but I do manage to get 1-2 bars of 3G at my house with AT&T, I figure I won't even get that with T-Mobile. So I am weary of the switch. I'll have to consider it though. I could also wait for the full rollout of the latest google voice (since it finally is bring VOIP without the need of hangouts) and just use that number instead.

So I contacted Straight Talk and ordered a T-Mobile sim card. It'll be here in a few days. I will post my findings after it arrives. Straight talk support says wifi calling works with all T-Mobile sim cards so we will see.

Hello all,
Okay, so I finally got switched over to a T-Mobile sim card (again still with straight talk). It took a while cause I had to buy a new one (the old one I had expired; who'd have thought?). Anyways, switching to T-Mobile solved all my problems and then some. Not only do I have Wifi calling, but also HD voice, VOLTE, Tethering, and 3-4 bars of LTE (previously on AT&T, I got 1-2 bars of 3G). I realize the signal issues is merely a coverage thing but I can say with certainty that switching to a T-Mobile sim card will give you all the advanced features. I hope this helps others who might experience this problem. I've been using AT&T (in one form or another) for the better part of a decade and can now honestly say, AT&T sucks.

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.

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.

Question Problem to use Motorola Edge X30 in USA

Hello, first of all I want to say that my native language is Spanish and I am using the Google translator to write this, so there may be writing errors and apologize.
Buy a motorola edge x30 and the imported import from China. The phone is unlocked to be used with GSM networks from anywhere in the world. When I bought it, I was with Metro PCS but in Metro I was told that the phone was not compatible with the 3G networks of them. After that I started to investigate and find a web page called kimovil and there I saw that the edge x30 was compatible in the USA with all the networks of 3 suppliers: Cricket, AT & T and T-Mobile: I choose to use change to metro by T-Mobile.
Immediately I left the T-Mobile store after making the change I have tried and could receive and send SMS, receive and make calls, and get access to the Internet without any problem. After a couple of hours of having activated services with T-Mobile, the phone could not or receive more calls (the Internet and SMS continue to work normally, the problem is only with calls). When I try to call someone, the call is not done and says "Hanging Up". I tried everything: Factory Reset, Networks Reset, modify network configuration, everything ... and I can not solve the problem. I went to T-Mobile to tell you about my problem and they tell me that the problem is not them but my phone.
If anyone knows how to solve this problem, I would greatly appreciate the help because I feel frustrated. Thanks

Good afternoon. I already managed to use the Edge X30 with the T-Mobile network. You just had to put the network selector on automatic so that you can use 5G, LTE, 3G and 2G as you see fit. The problem is that I realized that the phone only calls and receives calls in 3G and 2G, which limits not only the quality of the calls but also limits your coverage to be able to make calls since you can only make them in 3G and 2G . You who also use T-Mobile, does the same thing happen to you?

I'm not sure, but it supports 5G in N1/N3/N5/N7/N8/N20/N28/N38/N41/N78 and 4G in B1/B2/B3/B4/B5/B7/B8/B12/B17/B34/B38/B39/B40/B41. or check volte settings.

you may try to install "carrier services" app by google from the play store. it solves some of my problem with data connection.

Yes I have the same issue. Whenever I make or receive voice calls, the phone falls back from LTE to 2G. I looked everywhere on the phone for 'VOLTE' settings but could not find it. Does VOLTE work for this phone on Tmobile? Very frustrating.

Has anyone been able to find the solution for the calls switching back to 2g? I love the phone but this is extremely annoying. I'm on T-mobile. Thank you
