I just got my moto G power yesterday, purchased unlocked through best buy. I can't seem to figure out how to enable HD voice. I've looked through the settings, looking for advanced calling or anything like that, but I've come up empty. Google searches haven't been helpful for me either. Is HD voice working for anyone else?
no hd voice on this device using sprint in the us, what carrier/region variant are you using?
Verizon in the US. I just assumed it was a given with any new phone, budget or high-end.
If your carrier and sim supports it: Settings> Network and Internet > Mobile Network. You'll also have WiFi calling under the advanced settings.
I tried an ATT MNVO, it didn't give me any of those options, but every one of them appeared with a Verizon MNVO.
Unfortunately I don't have those options when i go to that setting menu. Might be unavailable when bringing an unlocked phone to verizon perhaps?
I bought a g8 power yesterday. My carrier supports VOLTE. before that I had xiaomi me a3 and there it worked after entering the "code" * # * # 86583 * # * # (an option appeared in the settings). Well, I can't find this option on g8 power and I can't even enable it.
Verizon does not allow Advanced Calling features on unlocked models. I was able to flash my unlocked Z4 to enable Advanced Calling: https://forum.xda-developers.com/t/...ng-and-root-with-xt1980-3-on-verizon.3994025/
But no luck so far with the Moto G Power XT2041-4.

So, I have an unbranded unlocked N8 I bought from Best-Buy assigned to my VZW account that was missing the "Advanced Calling" menu in settings. My wife's branded VZW S8+ has this menu. I tried the guides for other carriers to unlock WifI and HD calling, but alas, none of them worked. (I did however get the camcorder in the phone dial pad, but it didn't do anything) *******Still working on WifI calling**********
I spent hours testing settings in the IMS config via the shortcut app, all with no luck.
TIP: I called big red (VZW) on the phone and told them I bought the phone from bestbuy (didn't mention it was the non carrier unlocked version) and that WifI and HD calling menu wasn't on my phone. She told me my IMS wasn't configured on their end and she would update it. (This did not affect my grandfathered unlimited data plan)
Steps:
1. Call VZW and tell them you dont have access to HD voice on your phone and need help.
2. They will update the IMS on their end.
3. Turn off WifI, turn on mobile data.
4. Reboot and profit.
Ive uploaded a SS of the new option which wasn't there before I called VZW.
*****WARNING****** I seem to have lost the ability in the shortcut app to access the IMS launcher settings. Not sure if the 83mb update I took today caused it or not. Just warning you. I can still get into WifI calling via the app, however, it still crashes every time I get into it.
(Yes I know I shouldn't have taken any updates while we wait on eng. code to be released. Oh well I guess. )

You can always flash back to stock then...as long as it is server side as soon as it provisions, you should still get the goods...and be back to stock...this update does not lock you in...congrats though...
Does your Wi-Fi calling still not work? That's my only hangup of going with the Verizon rom.

Nope; works out of the box with Sprint & T-Mobile; haven't tested my AT&T SIM
You can get into IMS Settings by using Nova Activity launcher; under DEBUG INFO > IMS Information all should be true; if not VoLTE isn't enabled on the account or provisioning isn't completed; this can be done with a simple reboot.
Also; IMS Service Switch, make sure VoLTE Video is on for video calling; if/when VZW uses universal RCS profile you will have access to "iMessage" like features which Sprint/T-Mobile can currently use.
The Sad thing is total wireless morons have no clue what an ims is...

Thanks for the guide. Unfortunately after recent official Oreo software update, can't get into IMS Settings using either Nova Activity Launcher/Shortcut maker or through any other app.
Is there any way to enable "IMS Service Switch" thereafter enable VoLTE so that VoLTE option would appear under Settings->Mobile Networks?
Please suggest.
Thanks.
I have tried this new feature coming with the stock Oreo ROM and received a message from my mobile carrier initially, welcoming me to WiFi calling. All network settings seemed to be working fine, I was also browsing internet with no problems, all apps were connecting and responding as expected. However the first time I tried dialing one of my contacts I've got a message "Server error. Try again later." on the dialing screen itself. It looked like the call couldn't be connected. This happened to all outgoing calls, I suppose to all incoming also although I couldn't confirm that.
I tried many things like restarting the phone, turning data on and off, going into flight mode and disabling it, in the end I reset all network settings disabling LTE advanced services before doing that and enabling them again after the reset, but I still get that error. If I disable LTE advanced, all calls get connected with no problems.
Does anyone know if this is something with a list of supported devices explicitly enabled by the mobile carrier in their network? I am considering calling my carrier for more information but the fact itself I have got a welcome message means the device has been detected as part of the advanced services network. Perhaps there are some network settings I need to enter? Anyone ever used Axon 7's WiFi calling/advanced LTE features on any network?
Does that maybe include VoLTE which the carrier may not support?
https://www.4g.co.uk/what-is-volte/
Well according to the link provided and what I know, LTE is supported by my operator, but I wonder if it needs to be specifically tailored to a phone model by them and/or the 8.0 update by itself is not providing such functionality or it is limited by default. And I think it may be the first since ZTE products are never on the list of supported phones by any operator. But I couldn't claim it for sure as otherwise ZTE would not have included it at all with the 8.0 ROM and there are so many basic or very old models like LG K8 or Microsoft Lumia 550 that are supported.
Has anyone tried using "LTE advanced" on their 8.0 yet?

LTE Advanced = Volte
If your carrier does not support Volte, keep this option off.
WiFi Calling is something separate and not related.
If your carrier does not support WiFi calling, keep this option off.
You should still get LTE service with both of these options off. I personal find WiFi calling to work poorly, so I leave it off even though my carrier supports it. (TMobile US)
Also, there is a Q and A section for these types of posts. Don't post questions in the Guides and News section please.
Thanks for the input. Both of these options are reported to be supported by my carrier on their website. Also I always had LTE before 8.0 so simply wanted to try the new "HD voice and advanced communication service" as described in the latest firmware.
About posting this thread in the news & discussion section, this only relates to Oreo which was only recently released to the public so it is a completely new feature for the Axon. Most of the other threads are too general and since there will still be many people with 6.1 and 7.0/7.1, I would have hardly got any response whatsoever in there. For now I will keep this new option off and will contact my carrier for the support of the Axon and ZTE in general.
The phone is relatively new and since it's not mainstream most carriers don't support it yet. Some people say they have VoLTE enabled and it works but I personally switched to Singapore EX and it seems VoLTE isn't detected at all so I started digging and it seems this issue is present in most Chinese phones. (https://forum.xda-developers.com/t/guide-activate-volte-and-vowifi-simple-and-clear.4116051/) In this thread they used the Qualcomm tool and exploit the bug in EngineerMode on OnePlus phones which we don't have an access to and since we can't root or unlock the bootloader we can't modify build.prop or change any system files.
-----Maybe it's my carrier, maybe it's the Singapore ROM so please if VoLTE and VoWifi works for you could you post here which country you're on, which ROM version and if you changed region before or not.------
First a warning: If you aren't tech-savvy, experiencing issues or want to potentially turn your phone in a paper weight do NOT try this at the moment. We do not have the tool to restore your phone back (wiping data might work but idk). You can send your phone to Oppo for repair but you might have to wait for a month or two.
I don't know if you need to unlock your phone from the other thread to have access to this mode(I did have it all decrypted during this test) but in addition to the *#808# engineer mode and *#*#4636#*#*(Where you can check if you have VoLTE enabled) I found we have access to *#36446337#.
In *#36446337# I managed to enter "Protocol test switch" -> "MBN TEST" and switch my profile from Common-Commercial(I think it was this one) to Commercial-DT-VOLTE. The phone rebooted and everything is fine but "MBN Validate" is giving me an error when I run it and I can't test if it works because I'm currently out of the country and my temporary SIM provider doesn't support VoLTE.
It's probably nothing and the error is because of the lack of developer files on the ROM but I need people who can test if these profiles act like the flashing from the Qualcomm tool in the thread mentioned above.
So once again if you don't have VoLTE enabled and are feeling a bit courageous - give it a try.
I think the problem maybe for those that changed to Pakistan build on Android 10 and then switched to Singapore ex to get ColorOS 11 and dual SIM meant that things like VoLTE do not work on those builds.
I did it a different way as wasn't bothered about dual SIM. I was on A.46 UK , waited for EU to get ColorOS11 , then switched to EUEX on sec5 and downloaded ColorOS11 c.57 through Belgium VPN.
VoLTE is working for me. it's not present in SIM settings( WiFi calling is) however when I look at my call log there is a VoLTE HD icon next to all my calls, so is working.
Since being on ColorOS11, I have tried several different regions on SEC tool, EUEX dual SIM, Singapore EX, back to GB CPW to check still works and now back to EUEX. Build number always changes to different region in about phone when I have made any changes and check however VoLTE has always remained working for me and is showing as provisioned in engineer mode.
I am from Germany and have a phone with Vodafone FW originally. I switched region to Singapore EX, than installed the Pakistan FW and got C.5 and C.6 via OTA. I switched the region to EUEX (DUAL SIM) and didn't receive the update to C.57, so I switched back to Singapore EX and got the update to C.57 when using VPN Hongkong, which was quite funny.
VoLTE and Wi-Fi calling is working fine with Vodafone, but you can't toggle it in the hidden service menu, it's just active! You can activate or deactivate Wi-Fi calling in the regular settings, but VoLTE is just there, you can't deactivate it.
Both Wi-Fi calling and VoLTE are shown in the bar on the top. With the former Vodafone FW, VoLTE was not shown with an icon, but it was nevertheless working.
Hy here T-Mobile shown volte and Vodafone don't shows but on the status bar there is the volte symbol

I am in the same boat as you. I rebranded to Singapore to get ColorOS 11 update, to use 2 SIM and Call Recording, along with Theme Store, etc.
While on my previous phone (Xiaomi Mi9) I had VoLTE and VoWiFi and my carrier supports them and my SIM has that activated by my carrier, on Oppo Find X2 Pro it seems for them to work is needed special Modem Profile for the concrete carrier you use.
My Carrier is not listed at MBN Test Menu, I tried all the profiles available there, all Commercial ones and all Volte Branded ones and they are not giving me VoLTE and VoWiFi options available in Menu or VoLTE or VoWiFi functionality.
This method used to work on Xioami and Commercial EU Carriers profiles gave me the VoLTE and VoWiFi functionality with just Activity Shortcut access to this menu on Mi9 and simple dialer code to activate VoLTE and VoWiFi switch in Settings.
Oppo Find X2 Pro is not sold officially in my country and by all carriers here and that is why there is no Carrier Volte Profile for carriers from my country and thus it is not possible to activate VoLTE and VoWiFi with other Carrier Profile from MBN Test Menu.
Maybe if we find a way with a Dialer Code or some menu to activate the VoLTE and VoWiFi switch in Settings first this profiles from MBN Test menu will work...
I am out of ideas for now.

I'm pretty sure they force disable most of this stuff with region profiles (/etc/oppoRegion* folders)
At this point I honestly care more about GDPR protection,VoLTE and removing tencent/heytap crap than call recording and theme store which I don't use anyway.
So my plan atm is to wait for Oppo to release android 11 .57 .ozips so that I can flash back to european firmware then I'll see if changing region to EUEX Dual-SIM works and it's limitations.
This method might help people on EU roms with VoLTE, and I'll test it myself in the future, but at least for now *#36446337# lets us adjust MTU, 4G bands and some other smaller network optimizations.
Okay I don't know where to post this but I found *#649010# and this is where it gets into the spooky territory. I never tried toggling any of the options but I think "Full-port switch" option lets us connect our phone to the qualcomm diagnose tool just like the OnePlus phones from the Carrier profiles thread. I'm just documenting this code here so we know we have an alternative to the OnePlus LogKit.apk option in our Oppo phones.

Works for me no issue. Try adding cloudflare dns to your setup, tether your phones connection to your pc while disabling your main connection and adding the number values from the original thread, fiddle with the loopback driver, disable firewall in windows or your router. Everyones connection and setup is different you just gotta find a way to make it work on yours.
Tl;dr it works you just got to tinker with it

So I got the phone and it's working really well. My biggest issue is the lack of VoWifi. I called T-Mobile and the tech felt it should have it.
When I dialed *#*#4636#*#* (I think it's that), VoWifi is greyed out. Is there any way to use ADB or anything to force-enable it? There's no way, with the LTE/5G bands it has that it cannot be enabled on T-Mobile...

It can be related to your provider or it's SIM settings. I use Dual SIM. My Vodafone (NL) in SIM bay 1 has the WiFi-calling option. My KPN (NL) in bay 2 doesn't have it.

That's because Google has its own WiFi calling implementation, not using VoWIFI. It should work on just about any device.
I am able to get VoWIFI on T-Mobile after flashing Sony's Developer Binary (for the Xperia 1 ii), but unfortunately that one comes with some other unacceptable compromises (like no task switcher). Anyway the attached screenshot shows the service screen (dial *#*#INFO#*#*) on T-Mobile with this firmware. T-Mobile WiFi calling also works with even more out-of-fashion phones like my Nokia 9 PureView, so I would say this is definitely a Sony firmware issue.
In turn, the WiFi hotspot function does not work on Google Fi on any of my Xperias (1 ii, 5 ii, 1 iii). The client (e.g. laptop) connects to the phone and gets an IP address, but can never reach any website. It works fine with other phones (Nokia, Samsung,. ... and even the same developer image), and it works fine also with the Xperia on T-Mobile and AT&T. I suspect some iptables/firewall incompatibility between Fi and Sony's stock firmware.
I returned my phone back to sony because of missing vowifi.
T-mobile expert said its fully compatible but Sony expert said All Sony Phone dont have vowifi (disabled by software)
So I bought Xperia 1 III (along with a prepaid 3HK SIM card) when I was traveling in Hong Kong.
I inserted that 3HK SIM card to Sony phone, the Wi-Fi Calling was an option in the setting menu.
But after I returned to US, I swapped an Ultra Mobile SIM card to the Xperia 1 III, the Wi-Fi calling option is gone.
Before that, the Ultra Mobile SIM card worked perfectly on a Samsung Note 9 (also Hong Kong version) with Wi-Fi calling enabled. So it looks like it's a software problem.
Tried Google Fi SIM card, I was able to activate Wi-Fi Calling in Google Fi app, but not in phone setting menu.
T-Mobile VoWiFi is incompatible with the stock Sony firmware. You can get it back by flashing one of Sony's developer binaries onto your OEM partition (for "open devices" like the Xperia 1 ii and 5 ii but not 1 iii); however this also makes the phone not really suitable for day-to-day use (for instance, no "recent apps" switcher).
FWIW, T-Mobile VoWiFi works great on my older Nokia 9 PureView, which is definitely not a "known" device as far as T-Mobile is concerned. So the issue is limited to the combination of T-Mobile USA and stock Sony firmware. (Of course, VoWiFi also does not work on AT&T, but that's expected since they only provision AT&T-branded phones).
WiFi calling works on Google Fi, because they use their own implementation (not VoWiFi). Alas, WiFi hotspot functionality is broken on Fi - there seems to be something like a firewall/iptables incompatibilty between Fi and the Sony firrmware. The client (e.g. laptop) is able to obtain an IP address and ping the phone, but is not able to then connect to the Internet. (This, too, is fixed with the developer image above).
FWIW, as a workaround, you can install the T-Mobile DIGITS application and enable this feature on your account to make calls over WiFi. The only caveat, as I learned today, is that this does not let you make international calls. :-(

They are actually just meant to bring back some of the original Sony functionality (e.g. camera) on top of a plain-vanilla AOSP build. For instance you can build and install AOSP 12 and then flash this image to the OEM partition. Won't give you Google Play services though, so not really useful for most people.
However you can also flash it on a stock Sony firmware. (Just apply step 7 in the AOSP instructions above, without doing the rest). Fixes some issues, including VoWIFI on T-Mobile and WiFi hotspot on Google Fi, but unfortunately the recent apps switcher is then gone.
Only available for "Open Devices" like the Xperia 1 ii and 5 ii, but not 1 iii.
I know this is a roundabout solution, but it worked for me:
Port your number(s) to Google Voice. This will end your current wireless subscription.
Sign up for a new wireless plan, with new numbers. (*) If you order a new plan online, it's a good idea to do this first so that the SIMs arrive ready for activation before you start the previous step.
Set up Google Voice to forward your calls to that number. Or better yet, install the Voice app on your phone - you can redirect both inbound and outbound calls via this app/service. (I.e. you can use the native dialer to make Voice calls; however for text messages and voicemail you need to use the Voice app).
Optional: In the native phone app, block all inbound calls directly to the new number (remember, your primary one is now on Google Voice).
This also gives you the ability to send/receive calls, voicemail, text messages on a web browser. In other words, all of this is essentially a roundabout way of getting functionality similar to Google Fi; but remember, Fi's hotspot does not work on the Xperia.
(*) Apparently if your carrier is T-Mobile, cancelling 3+ lines and then signing up for 3+ new ones won't give you the same discount as the original signup. According to a local T-Mobile store rep I talked to, if you cancel and recreate service within 90 days, the system thinks you are trying to somehow cheat on discounts. Weird -- I ended up going (back) to AT&T for this reason. You may also consider T-Mobile MVNOs such as Mint Mobile. (**)
(**) Oddly enough, in addition to better overall coverage, I get much higher download speeds on AT&T LTE/LTE+ compared to T-Mobile 5G (NR/NSA) - even in a place with full bars on both carriers. I did a test today with two SIMs in the phone - on AT&T I got 100 Mbps down on first try, whereas on T-Mobile the best I ever got (20+ tries) was ~30 Mbps down; typically 15-20. Not sure if this is another artifact of the Sony firmware, YMMV.

Course, if you only need to make domestic calls while on WiFi, T-Mobile DIGITS is the path of least resitance.
Has anyone enabled on other variants?
I've heard that for instance, the India variants can call&SMS.
I have all the '20\21\22 T-Mobile & Metro tablets from multiple brands. All except for two can receive SMS but nothing else. One of those (LG) lost SMS function after first software update, the other is their first 5G (Alcatel) with everything locked down- can't even view APN in Settings (returned for this and being slow performing).
Additionally, I have an Octamax tablet that can call&text- thru Lifeline\Pandemic free phone\internet programs, which uses T-Mo network.
1. All the APNs in all the tablets (including Octamax) & several phone lines are identical- either originally or I added a new one.
2. I've sideloaded the manufacturer & Google versions of Phone, Messaging, Contacts + their supporting files- but nothing advanced like into System partition, no rooting or recoveries. To no avail, have tried old & new file versions.
3. T-mobile supports tablets with calling & SMS functions like the 2019 S6 Lite- in fact offers a troubleshooting section. (I don't have this tablet, '22 version only sold here as WiFi version).
Any ideas? Even other models from somewhere else?
Thanx
