After changing carrier to T-Mobile, I've noticed my N910C 5.1.1 doesn't have the Wifi Calling option. In theory, even if C version doesn't support Band 12, Wifi calling should be possible since it just uses wifi. Anyone with the same device found a way to get wifi calling with T-Mobile?

I have SM-N910U model of the note 4 and would like to know how I can enable voLTE. I know my phone supports it, but I can't find it anywhere in the settings nor is it active. My carrier has voLTE, but the phone data drops to 2g when I make calls. I would like to know a way to enable voLTE, so the data stays at 4g while on the call.
Or is there a way to add volte to international roms seems like it is only for carrier branded phones
I have the same problem with Galaxy Alpha on the Metro/ Tmobile Network.
LTE drops to 3 G on calls and often kills Data
during and even a minute or so after the call.
Not good for multitasking- this is a Factory Unlocked Alpha NOT a native Tmo / Metro phone .
The 4G LTE Tmo/ Metro Phones always have simultaneous voice and data so you can be on Web while on a call.
I think some have VoLTE and some have dual band simultaneously in the firmware specifically for Tmo.

Yes you are correct. VoLTE service can be enabled only with layer 1 modified kernel/drivers. The hardware itself definitely supports it, but firmware doesn't. Main reason the Samsung decided to disable this feature is because not all carriers in the world use voLTE service and enabling the service on the user end may trigger unstable and disconnection during call. I have contacted Samsung by Twitter and have yet to receive a response if they are going to enable this feature or not. Will let you know if I hear anything back from them!
Thanks. I wonder if some Dev here can do it for $ 100 .
Really like the size, speed and great Audio quality of Alpha and was going to get the larger Battery but I often can not get back on Internet for a few minutes after a call-
while the Phone says 3G (?) then it goes back to LTE and back to Internet...frustrating .
Am used to Metro PCS VoLTE since 2012 and had not considered this problem with a Factory Unlocked non Carrier Device.
No one reminded me there would be no VoLTE and sometimes no voice and Data simultaneously...
So DEVs figure it out for me and I will have a Tech here do the Install/ Download.
Alternative will be a too big branded S6 either Tmo or Metro which will have a better Camera, even slightly better than Note 4 but I love the small form factor of Alpha- this is Alpha 850 M.
Don't think Samsung will help although there is rumored to be VoLTE with Lollipop so there's a possibility.
Will Lollipop VoLTE perform like a Branded Metro PCS with LTE remaining on Display during calls and simultaneous Internet ?
Anyone have a Beta Lollipop for Alpha that achieves this ?
Thanks.
The toggle is missing for WiFi calling, and the enhanced 4g lte toggle in settings after updating OTA 6.0.1. Has anyone else noticed this?
On Verizon, We never had Wifi Calling, but the Enhanced 4G LTE toggle is still available.
On T-Mobile Wifi calling is still there on 6.0.1....
Anyone know how well the H870DS version works on T-Mobile network?
I'm using on TMO and it's working well.
I am accessing 4G LTE over band 12 so my signal is comparable to a TMO branded GS8.
Some things to consider:
1) No VoLTE (that I'm aware of) calling
2) No WiFi calling
Small Annoyances
1) Network mode resets to 3G after reboot, manually selecting LTE after reboots
I have the same problem with no WiFi calling, need it for work too :/
US regular unlocked model using Metro PCS Sim. E911 address is properly set up. I just fastbooted the stock may security update hoping it would fix the issue to no avail. Across all roms including stock I cant seem to get WIfi Calling to work or VOLTE. When making a call without WiFi on I can see the LTE drop to H, It does not stay connected to LTE. WiFi calling never shows as a wifi call in the dialer like its supposed to. Its causing me to miss calls and sometimes not be able to make outgoing calls. What in the world is the issue? Its definitely supported with both Metro PCS and the phone. I thought going back to stock properly would help but it hasn't.
I installed one UI 2.0 at my SM-G975F/DS All apps are working perfectly but when I turn off wifi or out of coverage wifi I loss GSM band network also. It could not enroll the GSM network. I use Vodafone 4.5G cellular line in Turkey. Should I turn back to Official Samsung Android 9.0 rom or there is another solution to fix this problem?
Wi-Fi calling works fine, but I don't have access to Wi-Fi at all times, and that's why I have a cellphone. I am just getting very frustrated because I get job related calls and if I'm not connected to Wi-Fi, I miss the call. Please help. LTE doesnt connect if there is no wifi. Actually I dont see LTE logo on the screen but when I start call on cellular line top of signal bars flashing green dot color.
I just noticed that I am talking on "VOWIFI" only so LTE mobile network is not working.
What could be the reason of loss network? It happens after installed Android 10
