I have an AT&T branded V30 that has been unlocked. I put my T-Mobile SIM in and am able to get LTE and make calls, but WiFi calling does not turn on.
I have an AT&T branded Samsung S7 that is also unlocked and it doesn't work either.
My wife has a T-Mobile branded Samsung S8+ that she's using on AT&T and I'm able to turn on WiFi calling for her number. Why does T-Mobile not allow this?

I spoke with their support and they said because it's not a T-Mobile phone, it will not work. When I first switched to T-Mobile, I used a Nexus 6P and was able to get WiFi calling to work. I bought the Nexus 6P directly from Google and not through T-Mobile.
From what I understand, wifi calling has carrier-specific "hooks" to Android system to allow wifi calling, so AT&T phone wifi calling only works for AT&T and T-Mobile phone wifi calling only works for T-Mobile. Nexus is carrier-free phone, so Google probably has set up wifi calling for all carriers in the US. It is the reason the custom ROM does not support wifi calling.
i have US998 Unlocked (Oreo) from BH. Use it on ATT prepaid, but I don't see the wifi calling. Do I need to call ATT to put IMEI in their system for wifi calling?

T-Mobile allows Wi-Fi calling on US998, and that's not a T-Mobile phone.

I also have AT&T Prepaid on B&H Photo US998. I think AT&T either doesn't allow that feature on AT&T Prepaid or doesn't allow it on non-AT&T phones. Either way I also do not have it for my AT&T number.
I do have it when I use my Google Voice number, of course.
Hi ChazzMatt,
Can I flash ATT firmware into US998 for wifi calling? If yes, can I return back to US998 firmware if i want?

Yes. You can flash the H931 TWRP-flashable zip to US998. (You need bootloader unlock and root.) With an AT&T account you may get Wi-Fi calling.
IF it doesn't work, very easy to return to US998 firmware.

Hi,
I've been offered a cheap unlocked refurbed V30 H931 variant and I was wondering if it will work with Mint Mobile (T-mobile) out of the box or if I should flash it with H932? My SIM is already activated and working on my phone, i'll just be swapping it out of my old broken phone and into the V30. Also, I travel to europe a lot (mainly the UK) should I flash a different firmware before I go each time to ensure I have the best radio and can connect to 4G service? My old phone is a UK phone and I don't get US 4G with it irritatingly.
Thanks!

Is it likely to work with T-mobile/Mint out of the box? Is there anything you would recommend I do to improve signal/performance with T-mobile/mint on the AT&T variant phone?

AT&T H931 is locked to AT&T. You'll need to Frankenstein it to carrier unlocked US998. Many are running US998 on T-Mobile.
I'm getting an unlocked 931 tomorrow, and will be trying it on mint mobile. If it's unlocked (as the seller says), I think it will work on t-mo network. It certainly has all the LTE bands needed (except 71 unfortunately).
I'll post back if it works or not.
I can say that the unlocked 931 I got works on mint mobile. The LTE signal isn't very strong but the download speed is good and everything else works fine. Really like the v30, what a nice phone.
Hello all. I have an LG V30 unlocked from AT&T. I am currently in the market for some different phone service. I was looking to switch to T-Mobile. However, when I went to their BYOD Check Compatibility page and typed in my IMEI, it said my device was not compatible. Will I still be able to use T-Mobile, just miss out on a few features, or is it no use to try and get T-Mobile service? I have checked that my phone supports all of T-Mobile's bands save for band 71. I figured all I needed was a GSM device and a new SIM card. Am I unable to switch to T-Mobile, can I switch with limited features, or does it operate at full support on T-Mobile, just an error with the website? Any help would be greatly appreciated.

If your AT&T H931 phone is actually carrier unlocked, it will work with U.S. T-Mobile.

Thank you for your quick response. I will probably see if I can switch to T-Mobile now. I am still curious though. Why would T-mobile still register my device incompatible? Is it an error with my IMEI or the unlock? Is it something on T-Mobile's end?

AT&T H931 is normally carrier locked to AT&T. So, normally it won't work on any SIM card not affiliated with AT&T. T-Mobile knows that. However, you say it's now carrier unlocked. But there's no way for them to know that, just by the IMEI.

That makes more sense now. I can confirm that my phone is unlocked because I have actually used it with T-Mobile MVNOs in the past. I just didn't know if a full blown T-Mobile card would work in it, being scared of the website check and all. You've helped me to clear all this up and I can't thank you enough.
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.

Yes. U.S. T-Mobile even has WiFi calling on US998 and it's not their branded phone.
For AT&T WiFi calling however you need AT&T branded H931 phone and be AT&T customer.

You will probably need a local version ROM to make Wifi calling work. For example, in the US people on Verizon (or a Verizon MVNO like myself) need to run VS996 in order to have Wifi calling work... so you may need a carrier-specific ROM as well.. Even after that, you may need to perform a few additional steps (I did) to get it working...

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).
