SO, I've searched the forums and no one has seemed to answer the question. They either skip over it or it just goes unanswered. Is there any way to get VoLTE to work on any other carrier than just Verizon on the G3? The phone supports it, the modem itself supports it but I'm not sure if it's locked down software wise to only be available on Verizon or if it'll be available on other carriers. I'm currently using an AT&T MVNO and I don't have the option available, the only phone I've had that didn't switch from LTE when on a call was my Lumia 928 (but that was when I was on Verizon itself) - the question stands - is VoLTE an option on any other carrier besides Verizon using this phone? I'm rooted running Jasmine 9.1 debloated w/Xposed.

My question remains, when carrier unlocking an s9 or s9+, is there any way to make it available on different network types like say if the phone started out using a carrier that uses CDMA, is their any way to flash it to utilize t-mobile's frequency bands?
I unlocked two galaxy s9+'s that were on xfinity, which uses verizon towers. The two phones did unlock, but only for carriers utilizing CDMA. I was hoping they would be able to be used on t-mobile after unlocking, but they can't. Only messaging and data works using a t-mobile SIM card. Verizon works fine. SO my question still remains, is there a way to make it work?
I used itekimei .com to have the phones unlocked, as I found they were suggested here on XDA. And they weren't really able to answer my question either. They said it should work with t-mobile, but the conversation ended with "t-mobile is having problems with unlocked phones." This is super frustrating trying to get an answer.
Edit: I found this forum https://forum.xda-developers.com/galaxy-s9-plus/help/sim-unlocking-sprint-samsung-galaxy-s9-t3783571 which debates whether it will work or not. Also this one specifically about Xfinity https://forum.xda-developers.com/galaxy-s9-plus/help/xfinity-mobile-unlock-service-t3796349. But mine didn't work. I don't think U.S. S9's are cross compatible from CDMA to GSM. I have been searching and searching and can't find a way.
Yes, the US unit hardware is cross compatible. Heck, Verizon itself isn't all CDMA. They are phasing out CDMA soon and most of their network is LTE.
I have a US unlocked S9+ and can use any carrier in the US. You could too, all you need to do is flash the US Unlocked firmware to the device using Odin.
Your problem may be the Xfinity firmware restricting certain bands is all. Or possibly the device isn't really unlocked.

Hello,
I just bought the S9+ unlocked today at best buy. I love the phone and I opted in for unlocked version so that I can root the thing later if I wish.
So, I would really like to have the HD voice option, but I found out that you need a carrier phone to be able to have wifi-calling and hd voice. My parent can hear me great on their end (they have iphones) but on my end I have the same old ****ty voice quality.
Is flashing ATT firmware (and getting their bloatware) the only way to get the option? Right now, when I go into settings-> connections-> mobile networks, the option isnt even there.
Reason is the same as I posted on a different thread. Flashing at&t firmware will not fix the problem. Subsequent comments in the thread may be of interest.

Ouch. That sucks. I read somewhere that tmobile and sprint don't lock unlocked phones out of their volte and wifi calling. Does Verizon use same tactics as att or will they make it available to me as well?

Yeah att doesn't have volte on any unlocked Phones. I put a sim in my Sprint S8 and it dropped to H+ during the call where TMO and vzw stay on VOLTE on my phone.

Same issue in Canada - Carrier Unlocked device purchased do from Samsung & none of the Canadian Carriers support VoLTE or WiFi Calling - This is extremely unethical on the part of the partnership between Samsung & the Carriers! We all know that the Carriers are Samsung's biggest customers - But to make key features unavailable is unconscionable! ?

T-Mobile and Verizon customers both get VoLTE on Samsung factory unlocked phones. AT&T restricts by IMEI (as well as requiring their firmware). Sprint does not yet offer the feature at all on their network. It is unclear whether unlocked devices will get it once they do deploy it. Time will tell.
Hi g8x have a wifi calling?
Yes, my US version does.
Just recently got the unlocked version with the dual screen bundle (LM-G850QM). I'm using it on Verizon and the Wi-Fi calling is working! Just FYI as Wi-Fi calling never works on Verizon with unlocked phone that didn't come from Verizon. I did already have a Verizon SIM.....
No such option on the Canadian model.
Not even VoLTE.
I'm on the Rogers network, btw.

Wi-Fi Calling (and other features such as VoLTE) are supported by the LG G8X so long as your carrier has enabled them.

I find it odd that you don't have the option fir VoLTE Or VoWi-Fi... Rogers (at least last time I checked) supported all the IMS features, being VoLTE, ViLTE, VoWi-Fi, and ViWi-Fi. Is your phone purchased from Rogers?

Mine has it on Bell.
True, Rogers support all the services, but they seem to operate on a white-listing model. If the device is not in their allow list, those features will not work.
Another example is the OnePlus phones, same thing.
But usually I see the option but it just wouldn't work. On my phone, it doesn't show at all. Unless LG software hides it automatically, I'd say its not there in the firmware.
This is an unlocked carrier-free Canadian model, not a Rogers phone. Rogers don't actually offer it at all.

Aaahhh.... That makes sense. I tried porting a HTC 10 from Bell to Rogers and had the same issue. They told me it was because the phone wasn't on their whitelist of allowed devices, even though I had the service working under Bell. I'd be willing to bet that the IMS Config file indicates that its to hide VoLTE and VoWi-Fi unless the network supports it. You can try using *#546368#*850# and see if it gives you options for VoLTE in the hidden menus. Likely under IMS Settings.
I can vouch for the G8X on Telus. It does support VoLTE and VoWi-Fi.
When the LG G8X was released Rogers did not carry it, I don't think the carry G8 either, that's how much the LG brand fell, it's only fanboys or people like who gave LG another chance to do better but as you can see they are not doing better, just going on the expectation if they build it suckers will buy it.
I tried the unlocked Sprint one and no VoLTE and no VoWifi. Does anyone have the unlocked ATT version LM-G850U on TMobile and if so, do VoLTE and VoWifi work?
Got one today.
No go. No VoLTE, no VoWifi.
I have a sprint version .someone find tricks to unlock
This VoLTE method probably does not work for Sprint version, but maybe someone can try it on AT&T version?

Those switches are greyed out on mine, which is (unintentionally) the Canadian version. But I have been told it is greyed out because VoLTE/Wifi Calling aren't enabled on the carrier side. In my case Ting says that my phone has LTE Band 12 and therefore VoLTE, but that will only work on ATT. A bit confusing because (like I said) the particular rom on my phone is Canadian (LMG850UM20e), so why ATT? The explanation for that, it seems is that ATT, (Sprint), and the unlocked Canadian version have the same sub-model (of the G8X - LMG850): LMG850UM. The USA unlocked version a different sub-model (LMG850QM), the rest of the world has yet another sub-model (LMQ850EMW). See this reddit post on the different models: https://www.reddit.com/r/LGG8X/comments/hvqdy4/hey_g8x_owner_what_is_the_submodel_number_and/
As far as I know all models (LMG850......) have the same hardware, the only difference are the roms, which artificially disable certain capabilities of the phone. I am pretty sure my phone would do VoLTE just fine on Ting (or most other carriers). The thing wrong here, I think, is that the IMEI and other specific identifiers of the phone artificially show that the phone does not have the functionality.
With all that said, I am still trying to find my around this problem. I'm considering flashing a different rom, tho not sure if that'll change what the IMEI and the other specific identifiers tell the cell carrier about compatibility. There is one report of T-Mobile supposedly fixing the same problem for a customer, see u/Veshtarii's comments on this reddit post: https://www.reddit.com/r/LGG8X/comments/irm2as/lg_g8x_unlocked_models_having_issues_with_us/
I also plan to keep updating this XDA forum post https://forum.xda-developers.com/lg-g8X/help/unable-to-enable-volte-wifi-calling-t4185809 with what I find out about this problem, potential solutions, and hopefully what solves it. Hopefully my post will be useful to those with the same problem.
I have concluded it's not possible on any TMO towers. See my forum post for more details: https://forum.xda-developers.com/lg-g8X/help/unable-to-enable-volte-wifi-calling-t4185809
Odd since t-mobile now owns Sprint. You would think t-mobile would allow or update the sprint version to use wifi/volte etc..
Perhaps future t-mobile firmware/security updates will patch the sprint to use these services.. Certainly NOT customer friendly for those who migrated from sprint to t-mobile.
I can understand the att version not working w t-mobile but not the sprint version

As far as I know, only the official US unlocked version LMG850QM has support for TMO VoLTE. None of other variants will work.

Maybe, I'm not sure still, even after all the research I've done. But I don't know everything of course. Also, after looking on ebay, the LMG850QM is like 450$ at the cheapest, compared to the 250$ of the LMG850UM ATT or Sprint versions, (the Canadian unlocked version is like 200$).

If you look in my forum post I referenced to in the previous comment of this post, I reference a reddit post where there is one person on sprint that got it working with a TMO tech person. That's the time I've heard about getting it working on T-Mobile.
This MAY HELP
I have a Sprint unlocked version, runs on T-Mobile. No wifi-calling menu.
BUT I downloaded and installed an app from Play Store called Wifi Calling written by Widget7 (get the right one), This simple app appeared to turn on the wifi-calling feature in the hidden menu. Long story short, I got wifi- calling on T-Mobile.

The WiFi Calling app only reveals the hidden menu, nothing more.
T-Mobile have VoLTE on by default. You can disable it by selecting different types of mobile networks such as Automatic 3G/2G, LTE/3G, or 2G only. I have no experience on this.
I have confirmed this by dialing *#*#4636#*#* Both data and voice are over LTE. And the VoLTE on/off button is grayed out (based on the type of mobile network selected).

I mean does it matter which variety of the phone I have?
if I have a sprint model, will it work fully on tmobile with volte and wifi calling?
I currently have a unlocked T-mobile S21 that I am using on a Verizon based MVNO. Is there or would there be any benefits to switching the firmware over to Verizon instead of using T-mobile that's on the phone?

I'd suggest switching to one of the 'open' versions, that has a multi csc capability and should thus have all the necessary ability to use the mvno you prefer. The t-mo rom may work, but it almost certainly won't have the full capabilities, such as all bands used, possibly volte working, vowifi, and there may be other things also.
Thank you. You make a valid point about going to a unlocked version.
I tried to flash the Verizon firmware along with the user_data files with no success.
I still get all of the T-mobile splash screens and all of the their bloatware. The service provider software version still states TMB/XAA,TMB/TMB but my baseband and build number are Verizons. Maybe I am not knowledgeable to this extend.
All I would like to do is get rid of T-mobile and make it a Verizon phone.
