I like the WiFi calling feature. Right now with service FUBAR in my area for what they say is a couple of weeks I actually need it. Could it be as simple as transferring a few apks like the phone, etc... or is it more complex than that. Forgive my ignorance in advance I just switched to T Mobile to get custom recovery back but I am running into all sorts of weird stuff I haven't seen before. I guess it's 4.4 related or even bugs in the S5 rollout.

I have a rooted SM-G900T with custom recovery to address the reply below. I want to be able to have wifi calling on any klte device Firmware based ROM-- namely the SM-G900F Firmware based ROMs.

Thanks a lot for any help at all....

You offer very little info, such as the type of phone, are you rooted ,what rom you are using, etc,etc.

You need either:
1. Native T-Moble phone with wi-fi calling standard like SM-G900T.
2. If you're rooted w/ non-stock ROM (but still has to be T-Mobile phone), the ROM you're using needs to be based off stock Tmo firmware and have the correct code in it to work.

You will not get wi-fi calling on non-Tmo phone or non-Tmo firmware (like int'l firmware runnng on Tmo phone).

Sorry for being vague, I meant computer code (programming language) for the Wifi calling to work. This will only work on native Tmo phones.

So, it's built into TMo's Firmware overlay? Since all these models are identical it stands to reason that firmware could be altered and/or apks added to make it work. The "code" might be applied or incorporated. Might. Unless it's proprietary. After all the SM-G900T hardware is identical to a SM-G900F.

There you go,you got it,it's proprietary.
