Unlocked, developer HTC A9 Android 7.0 Issues

My daughter has an unlocked HTC A9 that just got an Android 7.0 update 2 days ago. Our carrier is T-Mobile USA and when the phone had Android 6.0.1, it had VoLTE and Wi-Fi Calling features working extremely well. Now after Android 7.0 upgrade these 2 particular features are gone from the software.
Can someone with an unlocked HTC A9 on T-Mobile USA check if their VoLTE and Wi-Fi Calling options are missing as well after Nougat upgrade? Thanks in advance.

I did have the option in settings to switch VoLTE on or off, and it does seem to be missing here. If you want to know if it is on or off, go to phone and dial *#*#4636#*#* and click on phone information. Scroll down until you see either turn off volte provisioned flag or turn on volte provisioned flag. If it says turn off volte provisioned flag that means VoLTE is on. For the Wi-Fi calling, there is an option in settings for it I believe. Go to the call tab under setting and scroll all the way down to calling accounts. In that part of settings there is settings for "internet calling". Not sure if this is what you are looking for but this is what I found
Hope it helps, and good luck

I have an HTC A9 (oem unlocked), on T-Mobile USA.
VoLTE and Wi-Fi was not enabled by default until I manually forgot and reconnected to my Wi-Fi network. Afterwards, I went to settings, Call, and scrolled all the way down. There's a new section called "Enhanced Call Service" and VoLTE and WiFi Calling are now options available.

OK. Thanks. The tip about "forgetting" the network and re-adding might be worth trying. But only later today, once I get home.

So I deleted/"forgot" all of the Wi-Fi networks. Rebooted the phone. And still no Enhanced Services with VoLTE and Wi-Fi calling area under Settings --> Call. next step would be to do a factory reset and see if that helps.

Have you tried a network settings reset? It should be under settings>backup and reset

I'm having the same issue. I'm wondering where the Wi-fi Calling feature is. I have the US Unlocked/Dev edition and the "Wi-fi Calling" tab isn't under "Mobile Data" like it was on 6.0.1 .

I have the unlocked a9 on tmobile and everything worked well immediately after updating.
I have yet to make an actual call over wifi on nougat but sms worked fine and volte certainly works.
The only strange thing is the lte indicator seems to be the verizon one
Perhaps you should try taking the sim out, restarting, putting the sim back in and see if that makes the phone recognise it needs to use tmo settings?

I am on 2.18.617.21 and can't find these settings. How to get them back. Unable to make or receive calls on my mobile since mine is an LTE only network. Tried factory reset and changing CID to 11111111, but nothing worked.

Can't activate wifi calling on rooted phone?

I have a google Pixel on Android 7.1.2 on Verizon. I've had wifi calling activated the whole time that I've had the Pixel, on various cell providers, until yesterday. Decided to root my phone to be able to use "Radio Control", an app that will put the phone into Airplane mode when connected to wifi. Did that yesterday, and since then I've not been able to activate wifi calling. My phone is stock other than being rooted...I tried the Radio Control app, and it worked as it should. I've just removed it again, until I can get wifi calling activated. Oh, by the way, rooted by unlocking the bootloader, putting TWRP recovery on the phone, and then installing SuperSu via TWRP.
I've tried:
-Flushing app caches in "Storage", and flushing the phone app cache.
-Having "My Verizon" app on the phone.
-Resetting network settings.
-Activating with and without being in Airplane mode, always with wifi connected, though.
-Removing and restoring "Advanced Calling" setting.
The only thing I haven't tried is that one with the live chicken, a pentagram, and incense. That's my next thing to try.
Any suggestions? I'm really amazed that I can't activate wifi, since Verizon suggests this to stabilize wifi calling for their customers. I guess that they've never actually tried it themselves. Does anyone have wifi calling activated on a rooted Pixel? Do you remember doing anything in particular to get wifi activated, other than trying repeatedly to turn it on in the phone's settings?
By the way, the reason that wifi calling doesn't seem to work well on Verizon isn't wifi calling functionality, wifi calling itself works fine. It's because Verizon only allows the setting "Cellular preferred" for wifi calling. You cannot set "Wifi preferred" for wifi calling. This means that the cell radio is busy nearly all the time in a low cell signal area (like my house), working to make the cell signal usable. I noticed that there was much less battery drain while I was testing "Radio Control" since the phone was in Airplane mode, but I didn't have wifi calling activated at that point. Wifi was connected (of course), but wifi calling was not activated.
I hope that this is all clear, and that someone out there might remember something helpful for me. Or at least be able to tell me that wifi calling can or can't be activated on a rooted phone. If I can't root and get wifi calling activated, I'm going to sell the Pixel, as it doesn't meet my needs. I also have an iPhone that works perfectly with wifi calling on Verizon, but I'd much rather be using the Pixel.
Thanks!

I'm on Verizon and had that happen and found it was because of the theme i was using. Just had to reapply the theme to settings and all fixed. Also, I just checked the settings and you can set it to WiFi preferred.

Sounds good, just a couple of questions. First, which theme? Where do you access the particular theme in settings that you're referring to? The only theme that I've changed from default is the keyboard theme.
The other question is how can you change the wifi calling setting to WiFi preferred? Do you click on the wifi calling setting that has "Cellular preferred", and a menu comes up that includes "WiFi preferred"? I don't get that menu when I click on that setting, all I get is a setting for "roaming", and for 911 address, nothing else.
Also, which Android build are you on? I'm on Android 7.1.2, build NHG47K. Are you on that build? Or maybe N2G47E? I was wondering about that.

I'm on the 7.1.2 K build with a downloaded theme-not in settings. I think you have to set up the emergency address for wifi calling to work. And yes it's roaming preferences where you can change to WiFi preferred.

Just did a factory reset to try removing root and then activating wifi calling unrooted. Then add root again and see if wifi calling sticks or goes away....
So I'm currently unrooted and am not able to activate wifi calling. Sounds like time for a call to Verizon...Should be able to activate wifi calling with stock ROM. Have done this one before *smile*.
Things are not going well...looks like the Pixel may be heading out the door, too much time spent for no results.

Did you update emergency address? That's has to be set up for wifi calling to work. https://www.verizonwireless.com/support/knowledge-base-208085/

Any other tips to get wifi calling enable? Whenever I click enable, it just goes to a generic error message and then nothing. So I can't even get to the screen to enter an emergency address. I have a ticket open with Verizon, but since I have an unlocked bootloader, I don't want to do a warranty exchange.

The rest of the story, used iPhone 6S Plus for a couple of months so that I could use wifi calling at home, and sold the Pixel. I did get very tired of the iPhone, even though wifi calling works perfectly on the iPhone on Verizon. So I got the new Verizon 4G/LTE Network Extender so I wouldn't need wifi calling here at home. That's allowed me to get another Pixel phone and use it at home without relying on wifi calling, now have 4/5 bars of cellular signal strength throughout my house. The Network Extender is a really nice piece of hardware, a great upgrade for the old 3G model that had no way to tell what was going on. The new 4G/LTE model has a web admin GUI page that has all kinds of useful status information on it. As well as a one-line display that shows each step in the startup sequence as it comes up.
The new Pixel works just as the old one with wifi calling on Verizon. "Cellular preferred" is the only setting available for wifi calling. Which means that if there's a low cell signal it will generally be used in preference to a strong wifi signal. Don't know why Verizon insists on this setting, I guess that they really don't want to support reliable wifi calling on the Pixel. I've thought about rooting my phone again to see if can get wifi calling working reliably, but now that the Pixel is able to use wifi calling and I don't need wifi calling at home, I'm inclined to leave it alone. In other words, getting wifi calling working perfectly isn't a good enough reason for me to root my phone *smile*. I can root it in the future if I have a good enough reason.
So the bottom line is that I'm pretty happy with the Pixel now, works as I need it to...just tried the Android O Beta, and liked what I saw there. Really glad that I'm back on Android.
Update: found an article here about how to change calling setting to "Wi-Fi preferred" for Pixel on Verizon...tried it and worked for me:
https://forum.xda-developers.com/pixel-xl/how-to/verizon-want-wifi-preferred-wifi-calling-t3622700

Wifi calling enabled but not working (VZW+Airplane mode)

Trying to test the feature before I go overseas. Wifi calling is enabled, HD voice/advanced calling enabled. When I check the hidden menu in *#*#4636#*#* everything is checked.
I turn on airplane mode and enable wifi. When I try to make a call, the dialer says "turn off airplane mode or connect to a wireless network to make a call". I am connected to Wifi though and signal strength is solid. What is the problem?

You rooted? Don't know if that really matters but, I had use adb to edit the settings database. I never could get it to work till I did that. No root needed. Just Google wifi calling preferred ADB.

2 settings need to be changed I forgot but I think one is to prefer wifi and the other is to make wifi the preferred roaming method.

I am aware of that guide for ADB. However that is for preferred WiFi calling when both cellular and WiFi are available. It shouldn't help when I'm in airplane mode.

Had same problem with Verizon Wifi calling, fixed it
I had the same problem on my OG 2016 Pixel (rooted) running stock 7.1.2 ROM on VZW, but now fixed - here are the steps:
1. Open Testing Menu (dial *#*#4636#*#* on dialpad).
2. tap the "Phone information" menu.
3. Toggle on the "VoLTE Provisioned" slider (this was toggled off by default on mine). (Also make sure "Wifi Calling Provisioned" is toggled on.)
4. Using the Quicksettings dropdown menu, toggle Airplane Mode.
5. IMPORTANT NOTE - When I tried the 1st time it didn't work because entering Airplane Mode greyed out Wifi icon and disabled all Wifi connections (and data icon showed "no service"), even though Wifi was previously toggled on.
6. To remedy this, drop down your Quicksettings menu again and simply touch the Wifi connections shortcut, wait a couple seconds and all Wifi connections will repopulate, and default Wifi connection should re-connect.
7. Now hit the back button to the Quicksettings dropdown menu, wait another couple seconds and the data icon should change to "Verizon Wireless Wi-Fi Calling" - Wifi calling should now work

I appreciate the suggestion. I had tried toggling all those options previously but I did it again per your instructions. It did not work.
My quicksettings text goes from "Verizon Wireless" to "Airplane mode" when it is enabled. Then when I put WiFi back on it goes BLANK. It does not say "Verizon Wireless WiFi Calling" like yours did. Any ideas?

I don't understand. I have a cellular signal and my wifi calling just stays on. All I did was change 2 values in the Database.

I guess I never caught that fact. Mine doesn't stay on all the time. But, as soon as I walk in my house it pops on. My wife has an S7 and I can't get hers to work unless I turn the cellular off. Evidently Samsung does not have the same settings database.

Perhaps a local router misconfiguration?

I've heard that a local Wi-Fi router mis-configuration may be the reason Wi-fi calling fails in some instances.
I would test it out on a different router, or have someone with a known good Wi-fi calling phone setup test on your router to eliminate that possibility.
I've also heard that Wi-fi calling breaks when upgrading to Oreo for some folks. Curious what Android version you're running?

It's not provisioned for VOLTE so wifi calling won't work. If you talk real nice to someone at customer service they might do it for you.

Thanks. I'll go to a location and try.

I ran into the same issue, possibly after Magisk install on custom RR Rom (Marlin/Latest April Oreo build). It had worked one time but I guess installing Magisk was the most recent change I could think of after which it stopped working with the error message reported by OP. Anyways the only thing that worked was to do a "Network Setting Reset" , then setup Wifi (Airplane mode on) again and Wifi Calling settings back to On with Wi-Fi preferred.
Note: Also in "Mobile Network" in Settings, need to ensure "Roaming/Connect to data services when roaming" option is selected for the "Wifi Preferred" option to stick.

Disable Wi-Fi Calling

I purchased a Global version 1+7P (GM1917) directly from OnePlus. Then I signed up for T-Mobile service.
I am having problems with calls coming in over Wi-Fi. However, in Settings under Wi-Fi & internet, there is no Wi-Fi calling entry, so I cannot find how to turn off Wi-Fi calling.
Is there another method for turning it off? A package I can disable? (I have root.)

either install the new onepluslogkit app and *#800# into oneplus logkit/function switch/volte+vowifi switches on
This option will allow you to turn on/off as above. but in sim settings/ Sim1/Enhanced Communications
Or *#*#4636#*#* and turn off provisioning for volte/vowifi.

Tried the OnePlusLogKit, but the *#800# didn't bring up anything.
Tried *#*#4636#*#*, but when I toggled 'WiFi Calling Provisioned', it would "stick" - the Update button produced an error, and it reset on reboot.

What kind of problems are you having with calls over wifi? I plan to use the 7pro on tmobile so I'm just curious

This may all be my misconstruing the problem. After turning off wifi call, I tried calling my wife (which was where I notice the problem), and we still couldn't hear each other. Yet when I call voicemail, I can hear it and I can change my announcement which shows that the phone does work both ways. Therefore, now I'm thinking that wifi calling was not the issue, and the fault is somewhere with t-mobile. The mystery continues.

The mystery deepens. Using Google Hangouts Dialer (which goes over wifi), calling my wife fails (nothing heard either way), but calling voicemail, again, works just fine. I just don't get it.

Thanks for this thread. I knew I saw that somewhere but forgot to check the SIM menu.
Why isn't it in settings search when even dev options are?
Why does TMO lie and way it is in the same spot as most phones, in their article specifically about the OP7p?
My issue in on a WiFi call, sometimes I can't hear them (but they can hear me), sometime from the call start other times mid-call, and turning off WiFi fixes it. I have 1000mb fiber and no other network issues. Too bad it doesn't work. Thanks for helping me disable it.

Question 2G on A13

Can anyone who has already upgraded a Pixel 6a to A13 tell me if the "Allow 2G" option is still available in Settings-->Networks-->SIMs ?
Some people on twitter are saying that they cannot set 2G as a "preferred" network anymore, not sure what it implies.

The option is still here yes. However, you can't set 2G as the preferred network type.

Try this..
Open Dialer
type :- *#*#4636#*#*
Click on Phone info
Select Preferred Network type & Scroll Down & select "GSM Only"

Thank you guys.
Current situation is bizarre for me. I need 2G working for voice only. My carrier is switching 3G off, and I cannot have VoLTE working (despite the corresponding option being enabled and carrier saying that it should work). Currently, when I make a phone call, the 4G data connection gets disabled and voice travels over 3G or 2G. When the phone call is over, 4G data connection gets back on. Since 3G is being switched off, if 2G suddenly became totally unavailable, I simply couldn't make phone calls anymore.

I believe you can get a number with Google Voice, and call thru the app. I haven't used it in a while tho.

Well, this is a Pixel 6a thread so not sure if the 4a had other changes. You might check on that forum instead/as well.

This is mine, Pixel 6a with A13

Very interesting....I just did a full wipe, clean flash to A13. Nothing special and I changed nothing.

Any chance of automating this with tasker?
I used "Toggle Network Type" app on earlier android, but not it can't set 2G as preferred type anymore.
Edit: actually it was Automate app that I used, but neither it nor Toggle network type work.

Not sure if you have tried enabling this option in the SIM settings (something to do with the Tensor Security settings as Google deem 2G to be less secure.

I didn't, because I don't have it. I'm actually on a different phone and rom, and just trying to find a workaround, this is the closest thread to my problem that I found on xda. I'm using Samsung S8, and this rom: https://forum.xda-developers.com/t/rom-13-crdroid-android-9-x-for-samsung-galaxy-s8-s8-n8.4516883/
