So, yesterday ATT turned off my EVR-L29. I called customer service and they restored it but told me that it is a 3G phone for calls and as such, will no longer work within the next few months. I did some reading and called today asking that my phone be provisioned and whitelisted. They took the IMEI number and another number from the sim and said they would provision. After that, I see a new high speed LTE switch but I don't not see a way to enable VoLTE. Has anyone been able to enable VoLTE on the ATT network...and if so, how? Thanks.

To preface this... I still cannot make calls, as those use CDMA, but I have data. I use google voice for calls anyway, so having no cdma is no skin off my back. This will probably work for the Pro or Mate 20
What I did:
Through Verizon chat, I requested specifically that the agent put in a request to add my IMEI to their database. I told them I know the device isn't supported and that I won't be able to make calls, and I am OK with that.
I added this APN information: https://apn.gishan.net/en/apn/verizon/huawei-mate-10
I turned OFF carrier aggregation
I then put in my tmobile sim for a week in the other sim tray, turned off the vzw sim, and let it sit for a week. I only enabled the sim slot a few times throughout the week, and today it finally worked. My guess is it took them some time to add the IMEI to their database.

I'm interested in using the Mate 20 X on Verizon too and also use Google voice but I see the Mate does not support LTE B13 700c. Is that an issue?
I have a pixel 3xl, up to date stock non rooted, on straight talk lte/cdma Verizon network. I got a text saying straight talk now has VoLTE so I tried to find it in settings but there's no option for it. When I search it it comes up but when I click it it goes to mobile settings and it's not there I did the *#*#4636#*#* and it's also grayed out there. I changed the network mode in that diag screen to lte/cdma to see if that helped, was on global before i think. Still no VoLTE and for some reason I can't make calls. I have data, can send and receive texts but when I go to call it says no network. Removed Sim card didn't fix it, restarted it. Safe mode doesn't help either. Tired clicking trigger carrier provisioning, updated the smsc. Change mobile network to lte only, back to global, lte/cdma. I have no idea what else to try. Straight talk is basically useless for customer service so I haven't even tried yet lol.
Update!! It works!! Somehow I either damaged my sim card when I switch from my pixel 2xl to this 3xl and it somehow lasted till now. Or when I changed my network settings something wrote to the sim?( And it messed it up?? IDK much about how the phone and sim interact with each other)... But I did have a 2 year old sim card, it did not have VoLTE or wifi calling capabilities I now realize. So I bought a new SIM card at Walmart and activated it though the straight talk app on my account and kept the same number. Works perfectly and I now have VoLTE, no wifi calling yet but the option is now there and lets me click it but it fails. Doesn't matter to me, I'm just happy to have VoLTE. I'm leaving this post because straight has horrible customer service and I could find anyone who ran into this specific issue.
I was finally able to get AT&T to get my VoLTE turned on. It took two chat sessions but finally I got them to turn it on.
VoWiFi... not so much. They wanted me to go in to a store, because the phone isn't an AT&T sold phone. The chat representative said they would do something to the phone to turn it on even if the VoWiFi switch is already turned on.
Side Note for VoLTE:
My suggestion is tell them you used the dial code "*#*#4636#*#*" and tell them you can see that the VoLTE isn't enabled. And if your phone isn't registering with the IMS info, let them know too.
Good Luck
Anyway here are the screen shots:
You sir are a saint, thank you so much for this helpful information.
That dial code doesn't do anything when I type it in for some reason.
I was able to get VoLTE on both mine and my wife's OP8 Pro by just having the phone agent register the IMEI and rebooting.
I have submitted a ticket with their advanced team for enabling 5G provisioning since we have the 5G bands (or at least one of them) for AT&T. I will follow up if I am successful.
yeah I came from the Note 10 5g on ATT and i didn`t have to do anything, I just put in my sim and turn on VOLTE and it just worked. but Vowifi is another story. lol, I`m going back to Tmobile in couple of months, at least they allow vowifi and 5g to work without the BS from ATT
Will be trying myself and will post if make any progress
I ended up with a MVNO provider Ultra Mobile as a 2nd line on SIM2 (need a 2nd line for work anyway). That gives me 5G+VoLTE+VoWiFi unlike AT&T.
really wish AT&T business practices change. It sucks that AT&T does their customer like that.
I have enabled Volte via PDC method, disabled overseas commercial and activated CU-LTE.
Everything works great.

*********UPDATE********** I bought a new sim from straight talk and VOLTE works now! (GSM compatible Straight Talk Sim card) My old sim was from 2014, so it wasn't VOLTE compatible.
I have an ebay zombie LG G710ULM flashed to latest Google Fi Android 9 software, I received an email from Straight Talk (Wal-Mart US cell phone service reseller) telling me that my LG G7 does not support VoLTE and my phone will be unable to receive calls in January 2021.
-Using a network info app, the app is telling me it is connected to T-Mobile towers (so I have a Straight Talk T-Mobile compatible SIM)
-I can't find any options to enable VoLTE in settings, and wifi calling is erroring out
I was wondering if there are ways to get VoLTE and Wifi Calling working (Straight Talk supports it, but not my current ROM/SIM).
I can switch to the following sims supported by Straight Talk.
-AT&T Compatible Sim
-Verizon Compatible Sim? If my phone supports CDMA bands
OTHERWISE MOST OF US WILL HAVE A PAPERWEIGHT IN 2021!!!!!!!!!
Same problem
I'm having the same problem. Any progress on this?
I'd like to know this too. Surprised there is no traffic here with all the knowledgeable people on this forum.
G710EAW here. BTW There was an Android 10 update just two hours ago from Android 9. Someone with an 'EM' phone in another thread said VOWifi is "working now" but how do others know if it's working when January 1st comes around?

If you guys have cross flashed roms, then volte will not work. It doesnt work for any of us who have crossflashed. Whichever model.
You need to be on original software. Looks like some licensing thing that volte requires. They need to provision volte for all the phones. Sounds like they are not interested to provision it for g7. Odd that even EAW model which has original firmware, they sent that mail too....
Sad/Odd to see your carriers are suddenly changing to only Volte.
Is there a way to put it back to original software? I actually don't need it crossflashed to anything because it's a Verizon originally and I would like to use it on that network. Or does it not work that way?

Main issue is that your carriers dont want to provision volte for your G7s. So no guarantee if cross flashing back to original will work.
There is crossflashing guide in guides section with which you can go back to stock firmware. Do this at your own risk.
In our country we have a volte carrier called Jio. They provide an app called jiocall. Using that app you could use their service even if your phone is not volte capable. You will have to see if there are such apps for your carrier. Thats the only non technical, simpler solution.
I have some information that might make all of you guys happy.
I was told by Safelink Wireless that VOTLE is a function of BOTH the phone *AND* the sim card.
Basically, if the phone itself is VOLTE compatible but the sim card is not, then the phone will be reported on their system as not compatible, and will ask you to upgrade your phone.
However if a VOLTE compatible SIM is inserted, if the phone does in fact support VOLTE, it will then work. That's because it's provisioned on the carrier via the sim card itself.
If you purchased a sim via the "Buy your own sim" package, e.g. online or from Best Buy, etc, awhile ago, then that sim is not compatible. You simply need to call Tracphone/Safelink and ask to buy a VOLTE compatible SIM (which costs 99 cents). Then when you get it, call their tech department to have them transfer the phone service and phone number to the new SIM.
You can dial the phone's service menu and go to the VOLTE/GPRI menu and if the options are there, then the phone supports it.
What's the correct service menu number for our phones?

Update, I recently bought a new sim and I have VOLTE right now on ULM android 9 latest security fix LG G7 image, running on Straight Talk.
took a while to understand lgup but my 710 oulm had a type oreo that the guy said couldnt be but i crossed flashed it to 10 i dont see the rom anymore and i hope i put it on another drive it was a canadian rom for android 10 works great otherwise im looking to get volte active in the *#*#4636#*#* phone menu you can see "provision for the setting under the radio on off but its a grey area the buttons dont work could be good could be bad its definately part of 10 but ?? grey areas preferred network could be sketchy to play with the phone initially on transition had incredible link up speed now its giving me a pain because assume i played with the connection preferences tab and its a registration error like dum just use the assigned sim guys and stop trying to mac or identify with every device anyway its the registration of a telephone number robo heads
Just updated this morning, we now have eSIM support (supposedly) with the second IMEI showing up in settings. I haven't tested it yet though, so ill try to later today.
Edit:
So my secondary carrier is GoogleFi, which won't recognize the available eSim. So I had to convert my physical TMo sim to an eSIM (permanently disabled your physical sim card). This allowed me to move my GFi card to the phone.
GFi app recognized the sim card and activated, however it looks like Samsung/TMo baked in a TMo network selection feature for this sim. Instead of recognizing that it's GFi with it's networks, you had to select if this card was a TMo/Metro/Assurance carrier. I selected TMo thinking that GFi uses them mostly around my locale that it'll work. However we now get the X on the signal chart.
My guess is this is the good ol network lock coming into play. So we got eSim and 2 sim cards...we're locked to TMo and Metro still. Hopefully better luck for those with Unlocked US phones
I have a Samsung version (still on TMO but not TMO branded) and got the update today with esim too
So new update: becareful with converting your Physical Sim to an eSim. I can't figure out why, and am on the phone with support, but the eSim for TMo doesn't register on the network. wifi-calling works for the eSim, but nothing else. In the Sim card settings, it detects an "unknown" carrier, whereas the GoogleFi (which doesn't work probably due to network lock) at least detected GoogleFi.
Edit:
So...whatever you do, don't listen to Help desk. They had me removing my eSim so that I can do the "scan qr" method even though I did the proper Convert to eSim method previously. The removal doesn't actually remove anything from the phone, so you can't "start over" hoping to try a different method. Even if it could, you disabled the physical sim, so you have no method of receiving the TMo verification codes needed to add a sim card to the phone. You literally lock yourself out of the network until they send you a new physical sim or reactivate your old sim
To reactivate the old sim, while forgoing the text message, is a 10min processs. Fortunately that's probably the most straight forward aspect. The 10min wait is to let the verification process timeout and it'll just activate.
I gotten it 5 days ago I really like the new features
What is esim?

Esim is where you can ditch the actual sim card and your phone have a built-in sim card manager to keep digital copies
I switched one of my other lines to my fold3 esim today (on TMO network) and been on with support for a while now they have no idea the issue. But it detects it as a T-Mobile network but it won't discover the number. It stays as unknown number. Can't use the data, calls or texts but it activated
Edit: after going back and forth with tech support, the issue has reversed itself. Now the esim has a number but no provider lol will keep this post updated
Edit 2: after more back and forth with some escalated executive support team they found the problem and fixed it. It's supposedly a bug in Samsung's esim that needs manual high level settings changed on TMOs end to fix on a per device basis

I'd like to say that after several days with physical sim and esim, I've zero problems. It just works. My only complaint is how voicemail is handled for the 2nd sim.
