Is there a way to enable voLTE through hidden menu?

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.

T-Mobile Wifi Calling in support in N910C?

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?

VOLTE/WiFi Calling

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.

WHILE USING JIO WITH VOLTE, other sim's internet connection not working.

There is a network bug, WHILE USING JIO WITH VOLTE, other sim's internet connection not working, only working while disabling jio 4g enhanced ( volte) setting.

Do you experience this issue on stock ROM too ?

Nope,

How do I restore VoLTE support?

Even though the Moto G6 Plus has hardware support for VoLTE, Lenovo scumbags removed the feature from the stock firmware of my country (Brazilian retail), which is updated to Android 9.0. The stock ROM does have a toggle for turning VoLTE on/off, but it's broken, because when I make a call with 4G on, the "4G" icon turns into an "H+", aka 3G. My carrier where I live supports VoLTE, and it works just fine on my mom's Moto G5 Plus on Android 8.0. Is it possible to re-enable VoLTE on stock ROM with root access, or the only way to get VoLTE support back is flashing a custom ROM that has this feature implemented?

I am from the Netherlands, and I have the same issue... Does anyone have a fix. My moto has bootloader unlocked...

I was mistaken, the G6 Plus does have VoLTE support, what it doesn't is 4.5G/4G+. Go to Phone info menu by typing *#*#4636#*#* , and see if "VoLTE provisioned" toggle is on. Toggle it off and on in case it's already on but you still don't see the 4G icon, which tells that VoLTE is enabled.
