[Q] Wifi Calling on L720 - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

I know that the L720T (triband) has been enabled with the newest update, but is there any word on when / if WiFi calling will be enabled for the 1st gen L720?
What exactly does the WiFi Calling enable? Is it just adding SIP, or is it more?
If Sprint doesn't release a new firmware for the L720 is it possible to port the WiFi Calling feature from the L720T to the L720?

You can flash TMO Roms on S4 as long as you use KToozens KTweeker kernel you can also flash international ROMs I9505 Roms I prefer these just be sure to flash new kernel before reboot of ROM or it will bootloop / softbrick..

[Q] How to use GSM SIM on Samsung Galaxy S 4 (Sprint SPH-L720) with 4.4.2 ROM?

Hi, I'm using the phone on GSM network outside the US, it had no problem when on 4.3.
After installing the 4.4.2 ROM (it is Sac's custom ROM based on official 4.4.2) I find it does not work with GSM SIM. There is no APN setting available, mobile network has no GSM option either.
Is there some hidden trick to re-enable GSM support on 4.4? Thank you.

Lg G2 D800 volte (Voice over LTE)

So T-mobile and AT&T are planning to stop supporting any device that does not have VOLTE capabilities by 1/2021. I have a couple of Unlocked D800 (ATT Version). Anyone know if its possible to activate VOLTE? When I go into the hidden menu and i tried to enable VOLTE, it says something like VOLTE packages not found. Anyone know if a custom rom will enable VOLTE?
