Wifi calling hidden on US unlocked model

Someone on AC has the us unlocked version that you can buy from Amazon and BH and is using tmobile on it. They said wifi calling is hidden on it but if you go searching using an app like quick shortcut app you can find wifi calling and enable it that way.
If anyone has the unlocked model have you tried this? If this is the case I might just order the unlocked one.

So has anyone tried this? thinking about ordering it this weekend so would like to know.

It IS there. in Quick Shortcut maker.
I'm on AT&T and it appears enabled by default.
Not sure if it's actually doing anything - but it's there.

I got it turned on.

How do we know if it's really working? I have bad service in my house - and I don't seem to see a difference.

On the LG website for the unlocked version it list Wi-Fi calling as a feature.
On my phone I switched it to Wi-Fi calling only and it let me make calls with it
http://www.lg.com/us/cell-phones/lg-US996-Unlocked-v20-titan

how do we enable it though? nobody has given any instructions lol. there's no clear spot for it on mine, and I'm running it on Verizon. I searched everything related to wifi as a shortcut from Nova launcher and found nothing.

I downloaded the app quick shortcut maker and used it and search Wi-Fi calling and you will find it that way, then make a shortcut icon to it.

crazy. mine was already enabled by default and set to use wifi as priority even when mobile network available lol. weird. I switched it to use wifi as the backup instead.

Doesn't work.....
I live in a cell dead zone and I tried doing this and I still get no calls. I have tried all the choices and none of them work.......

Has this been confirmed working on a US996 rooted with dirty santa?

It has been confirmed to not work on US996. I am not sure if rooting with dirty santa would change it.

That stinks. Im just confused to why it would have the capability but not work. Thanks for your reaponse.

H910 here.
I have the option in settings however when clicking on "Get Started" I get a dialogue saying I must confirm my address. Eventually this times out and gives a "network unavailable" error. Probably because its trying to contact an AT&T server but I have T-Mobile.

Wi-Fi calling on AT&T working
I was searching for this using the QuickShortcut app everyone was talking about and thought it didn't exist on my phone. For anyone who was searching for "WiFi Calling" and not "Wi-Fi Calling", you do need the hyphen and then I was able to change the setting. I'm hoping this saves somebody else some frustration.

hold on why is it confirmed it doesn't work? mines still on and i get HD voice often at home, and my lte usually sucks.. so im on wifi.

Activate WiFi Calling/ Encryption, Honor 8 Nougat (No Root)

So I've always thought WiFi Calling was interesting and when I bought this phone I knew there was no WiFi calling. Here is a method to activate WiFi calling. not sure if it works though as I have international data plans + calling.
You do this at your own risk.
1. Download Nova Launcher from the Play store.
2. Once installed add the activities widget to whatever home screen you like.
3. A window will open. Scroll all the way down to settings open it.
4. From there start scrolling until you see WiFi Calling with WiFi Calling settings right under it and long press either of them.
5. Congrats you have made it to the WiFi calling screen all you do now is hit that switch!
Encryption-
1. Do the same up until number 3.
2. click on settings and scroll until you find Encrypt Phone.
3. Do a long click and a screen will pop up and it will say something like make sure you're at 80 percent with the charger plugged in...etc
NOTE- I have not tested this option so proceed with caution.
I'll put some screenshots for those who want to see it first.
This also works to get encryption surprisingly.
If this helps you make sure to hit Thanks!
I take no responsibility if you choose to do this and end up damaging your device. You do this at your own risk!

Is this Carrier dependent?

If the carrier supports WiFi calling then it should work. I'm not too sure. Give it a try and see if it works if it doesn't then you can just turn it off. It should also work on any model but I only have FRD-L14 to test it with.

Just curious, have you tried to use the default launcher after you enabled wifi-calling in Nova? Will this feature still work in that case? This sounds really interesting...

I did not activate Nova at all when I used it. In the screenshots above you can see it is the default EMUI Launcher that I used to activate with.

As long as the bootloader is locked, the phone should already be encrypted.

Turns out, this doesn't work on my phone (FRD-L04) with T-mobile. I followed your instructions to enable the Wifi-calling setting with Nova launcher and then restarted the phone to make sure everything resets as the setting defined. Then I put the phone in the Airplane mode with only wifi signal available. Called a number for a quick test, but it asked me to connect to a cellular signal or turn off the Airplane mode first. T-mobile should have the Wifi-calling enabled on their end, and I am using their prepaid plan right now. I guess the only reason why it didn't work is Huawei has other hidden settings disabled this function at the root (not sure on the software or hardware level, though).
Let me know if anyone can make it work truly. Thanks!

You can't use WiFi calling while in airplane mode as long as you have bars it should work.
Ex. Say you're in Mexico and you got WiFi then you turn on WiFi and you should technically be able to get calls like if you where in the US.

Gotcha. Your method is similar to what OnePlus One people did before, and yields similar result--not really working. I guess we have to wait for Huawei to implement some function in their future EMUI release. They claimed they had a plan for EMUI 5 but not in this release in reality. Seems Huawei people are not in a hurry, possibly because the Chinese market doesn't have the demand for wifi calling.

That's true. I kinda didn't expect much from it but it will most likely be coming in a future update anyways

Using FDR-L14 with TMobile and enabling the WiFi Calling doesn't seem to do anything here as well.
That said, I am super excited to see that Huawei/Honor working on this!!!!!

My understanding is that Wi-Fi calling functionality is a combination of the radio + kernel. It's why AOSP-based ROMs have never been able to get Wi-Fi calling or SMS working, they don't have the closed-source drivers needed to make it happen. So in essence enabling it via a Menu item is simply toggling a UI switch with no back-end code to actually make the calling work.

1.) I bought Honor 8 with Nougat
2.) Called my service provider Ultra Mobile (piggy backs on T-Mobile) to enable WIFI calling, they took my E911 address and enabled it.
3.) Installed Nova
4.) Turned the WIFI calling switch to ON
5.) It didnt work in Airplane mode, it didn't work when I have WIFI and no cell reception. Not able to make calls.

This was already discussed in another thread a few weeks ago and no it definitely does not work it's just a toggle switch in settings Wi-Fi calling is not enabled on this phone. I personally tested it on AT&T sim using wifi in my basement where I can't receive a signal and multiple people tested it on T-MOBILE.

Will that work on Tmobile SimCard as well of just Verizon?

What about AT&T? Will It work

I hope that I'm wrong but I'm about 100% sure that this will not work for AT&T. AT&T actually requires a Specialized or particular APK to work. In my previous phone Galaxy S7 Edge these apps were installed during flashing of the CSC

Does not work on Sprint Note 8.

These features will work out of the box on T-Mobile including WiFi Calling as long as you have the correct plan provisioned on your account.

I tried this, but when i go to IMS Information everything is false and can't be changed. It also doesn't have the VZW VoLTE registration information at the bottom of that screen like you have. I see the VZW VoLTE profile under "IMS Profile", but forcing a manual register doesn't seem to do anything

If it is false call carrier to have imei whitelisted and reprovisioned, say it's for connectivity issues...bought from Samsung...afterwards you can see it change to true....you may have to ##SCRTN# to provision on your end...you may just need to update profile and prl...

I wonder if this will get wifi calling once I root. The rooting process uses a method of mixing boot files and essentially makes it a U1 rom with a Verizon csc but wifi calling isn't available. I'm going to give this a go to see if it'll enable it. If anyone has tried let me know. Thanks to the OP for this one.

Interested to know if this fixes wifi calling, if so that's the only reason I haven't checked out root - I get 0 signal at work, and depend on wifi calling for my primary cell number. Google voice works over wifi of course!

Any success with this?

Hey,
I can enable video calling but I cannot use it.
When I make a call, it just shows up for a second and turns off. Does anyone have this issue?

Calling fix for verizon (I can make calls again)

BLUF:
If your Verizon account does NOT have HD Voice enabled and the essential phone has "Enhanced 4G LTE Mode" enabled (which is a default setting) you may not be able to make/receive phone calls.
I had an older phone running a lineage fork that did NOT support HD Voice. For whatever reason that also means it isn't enabled on my Verizon account. It doesn't cost anything extra and isn't plan specific but until you enable on a phone (says VZW Tech) the setting stays off.
When I put my SIM into the new Essential phone I could make calls but it would NOT find a new tower. IF i was driving any distance I had to reboot the phone completely to get data or make calls.
As of a few days ago my data was always working (LTE+) but suddenly I could not make or receive any calls. Again, texting, internet, etc. was fine. (yes wifi was off to test this =)
I was on with VZW support trying to fix this when my essential trouble ticket was answered with:
Given that you are getting the LTE+ icon already, can you try this step and see if it helps:
Go to Settings -> More -> Cellular Networks
Disable "Enhanced 4G LTE Mode"
Make a phone call
Return to the Settings menu and re-enable Enhanced 4G LTE Mode
Click to expand...
Click to collapse
VZW said give it a try lets see. With it "off" I could suddenly make calls. With it back on I couldn't again.
VZW said I bet that's what we call "HD Voice" and I see its not enabled on your phone. He enabled it. I rebooted. Everything works again with that setting on or off.
I emailed this back to essential just to let them know what I did with VZW and got reply:
My understanding was "HD voice" was enabled on all smartphone accounts with Verizon, but I will add that as a step to check in the future.
Click to expand...
Click to collapse
I've been troubleshooting this with VZW and Essential for a while so very happy to find fix. I also went out and got a brand new SIM but that also didn't help. Both new and old sim worked in old phone fine but in essential no luck.
I had at first though unlocking bootloader / rooting had done something . I wiped and reflashed this thing 4 times yesterday trying different things to no avail.
I know some other Verizon uses were having weird issues so wanted to share.
I'll prolly never get so lucky with tech support synergy again in my life... but at least this one time they were quickly helpful.
MODs: If this should be in "guides" instead please move or I can repost

VoLTE with 6T on AT&T

Hi, I've seen where some users have reported success getting VoLTE to work on the OP 6 on AT&T, but I have not had the same success in the OP 6T. I followed the same steps and enabled it on the phone, which now shows that it should use VoLTE when available. I have also spent many (painful) hours in the phone with AT&T trying to resolve this issue, all without success. Has anyone else been able to get this to work, and confirmed that LTE data is still presented when in a call?
Thanks in advance!

I have the McLaren version and with TMobile and I can confirm that it is using VoLTE see picture below.

"technically" I'm using at&t, but it's a tracfone sim via Straight Talk. I enabled it for both VoLTE & VoWifi, and the LTE one took off but the wifi version did not.
I DID notice the difference in call quality. Much better audio response.

Yeah. I'm on AT&T and I got VoLTE working. I just made a call and did a speed test while on the call. Everything indicated it was still on LTE.

I had issues with VoLTE when I first got phone. Read my post from another thread. Basically had to wait for AT&T to get my line provisioned correctly. Don't know exactly what needed to be changed/activated.
sharksfan7 said:
I got my 6T on Friday. Used @crowsnestitsupport's instructions for the *#800# trick to get the VoLTE & WiFi calling settings to show. Popped in my sim. Had LTE data but didn't get VoLTE & couldn't get AT&T's VVM app to activate. Called support, ended up giving them my IMEI and not surprisingly it came up as Unknown Device. Guy basically said until the system can recognize the device there was nothing he could do to get VoLTE & VVM working. However after I got off the phone, I quickly realized I no longer had any mobile data at all. Called back, spoke to another rep, and she tried for an hour to get my data back. She wasn't able to. She had to escalate the issue and said it could take 24 hours or more to resolve. I figured out that if I changed APN from ATT Nextgenphone to ATT Phone I could at least have some mobile data, albeit only 3G. Wasn't until Sunday afternoon that LTE came back online including VoLTE. I don't know what had to change to get it all working. Just glad that it is now. Still no WiFi calling but I don't expect to get that.

It's well documented that that doesn't work, doesn't change anything. I spent two years with the OP5 and 5t trying to get them to enable VOLTE, in about 12 different ways and it never worked. Either you were on WIFI or just really, really special.

I appreciate the feedback, just wish I could get it working on mine. As much as I hate the experience, I'm thinking it might just be worth going to the AT&T store just to get them to use my SIM in one of their devices just to get VoLTE working on the line (and/or verify it works on one of their with it already activated)

So, I can now confirm that VoLTE works on the 6T. Basically, the system requires HDVoice to get VoLTE working. The solution? I bought a $25 AT&T Prepaid junk phone and enabled HDVoice and WiFi calling on my SIM. After that, I switched the SIM back in to my 6T and it is now working.

I did, numerous times. They submitted my IMEI to enable the features, and I was told that everything was set up correctly. Upon their recommendation, I went as far as sending my brand new 6T back and buying another one. It didn't matter how many people I talked to, it didn't work until after I used the junk phone to first get it working on the line.

When I first swapped it worked and then stopped. I had to put the SIM back in the AT&T phone and again enabled VoWiFi. I then pulled the battery, turned on the 6T, and inserted the SIM. It's been working on the 6T since.

Sorry to revive an old thread, but has anyone found out exactly what to do to get this working?
VoLTE was working perfectly on my 3T, albeit the only way to make the switches appear was with the VoEnabler module in Magisk.. but once they appeared, all I had to do was turn it on, and VoLTE was up and running. I tried the same thing on this phone after putting my SIM in, directly from the 3T; it worked for a few minutes, then the status bar icon disappeared and calls drop my connection to 3G, then go back to LTE once the call is over.. so clearly it has turned itself can off.
I then put my SIM card into my wife's At&t branded Galaxy s9, and after a few minutes VoLTE was working, using my SIM in her phone. I popped my SIM back into my phone, VoLTE was back working... Except, just as before, after a few minutes it stopped.
One thing I've noticed, while working correctly, under the IMS Service Status menu selection in the *#*#4636#*#* dialer menu -> Phone Information, it shows IMS Registration: Registered. Voice over LTE: available... But once it stops working, it says not registered, and unavailable respectively...
Since there are apparently people who seem to have it working, what am I not doing?
Could it be that the phone I put my SIM card into, is currently in use by someone else; someone else who also is provisioned for VoLTE? But what would be the reason it decided to stop working on my 6T and not my 3T? I used the same procedure to trigger VoLTE working on my 3T, and it never stopped working as it is doing on my 6T.
We work opposite shifts, and I used my few minutes we see each other a day to put my SIM in her phone then back into my 6T, I didn't put it in my 3T, which I will do next time I see her.. just to see if the 3T will hold onto VoLTE; that way I'll know for sure if it's something the 6T is doing differently than my 3T, or if I just got lucky before...
Any input or suggestions are welcome..
Edit:
Called AT&T customer service, put my SIM in the S9 and said I was unable to activate either WiFi calling or HD Voice, yet my wife's SIM in the same phone works.. they said that for some reason, my SIM was apparently attached to a non at&t Galaxy s9, she changed the IMEI associated with my SIM card and it's all good now.

With AT&T, If i enable VoLTE, i did not see the "HD" icon when making call. If i disable VoLTE, i see the the "HD" icon. Why is it backward?

Opposite for me... The HD icon only appears when I have VoLTE on, as shown.. perhaps something to do with using 2 SIM cards?

I got volte and vowifi enabled and only problem is that i cant see the volte icon on status bar.
