T-Mobile (G935T) or other variants running on AT&T - AT&T Samsung Galaxy S7 Edge Questions & Answers

Hi,
I'm on AT&T and planning on buying an S7 Edge. I'm trying to look for a unit with a good price and don't care if it's a different variant but I'd like to know what I'd be missing by not getting the AT&T one (G935A):
1. If flashing the AT&T firmware on the T-Mobile variant (G935T) or any other (Verizon, Rogers, etc), will it work just like the AT&T one and will it activate all the LTE bands? or AT&T will still not recognize it as an AT&T one? any other AT&T feature that might be missing?
2.- Does the VoLTE and WIFI calling on AT&T works in any other S7 variant? I think I read is possible but root is needed.
Thanks!

I can verify that using the Verizon S7 and S7e works with AT&T firmware. All AT&T LTE bands including VoLTE and WiFi calling work. No root required.

I have tmobile S7e that I flashed the AT&T firmware on. It's running great and works great.

Which Note 3 would work on MetroPCS?

Which variant should I get to operate on MetroPCS?
Right now, I have a Galaxy S4 SGH-i337 AT&T unit. It would only pick up Edge on MetroPCS (we're running on T-Mo's towers, of course). I had to use QPST to unlock the AWS 1700 band so I could pick up 4G in my area. Works fine now.
I am told that as of now, unlocking AWS is NOT possible on the Note 3, so basically I can only pick up whatever bands the phone can get, out of the box.
When buying the Note 3, I should get the T-Mobile variant [SM-N900T] correct?
A seller from Craigslist has a Factory Unlocked SM-N900T, but he told me that I should NOT buy it because it will not work on MetroPCS. So I am confused. But I figure if I buy the AT&T variant, I'll be stuck on Edge again with no way to unlock AWS 1700.
Advice, please?

[Q] AT&T friendly variants?

I currently have the AT&T variant of the galaxy s5 and I would like to get replacement that I can root, I know that most all variants are compatible on the gsm side but I would only want one that would be compatible with LTE on AT&T of course as well. Could someone please let me know the variants that would work on the LTE network for AT&T please. Thanks in advance!!

I suggest T-Mobile's variant, which is what I use on AT&T's LTE network with no problems.

Does this device's Wi-Fi calling feature work on the T-Mobile Network?

I have a very interesting question about using the AT&T variant of this phone on the T-Mobile network. As you may have noticed, AT&T is finally offering Wi-Fi Calling on their network, and this phone is compatible with such feature. My question is:
Does the T-Mobile Wi-Fi calling work on the AT&T variant of this phone?
Does the AT&T Wi-Fi calling work on the T-Mobile variant of this phone?
I'm on the T-Mobile network, and I'm considering getting the AT&T variant, but I'm not willing to give up this feature.

Any radio (LTE) band issues using G935F on T-Mobile usa?

Just wondering if there are any radio LTE band issues using a G935f on tmobile usa. I know the g935t supports 4x4 MIMO as well as some specific Tmobile supported radio bands, wanted to know if using the Exynos G935f international version would have any problems or missing bands since I'd be primarily using Tmobile usa.

I never considered the WiFi calling I use that a lot. I guess now there is a decision to make....
Band 12 is not usable by default as it's used only for VOLTE and the 935F doesn't support T-mobile VOLTE out of the box. If you are rooted, you can download a CSC selection tool which adds VOLTE/Wifi calling/Band 12 support. Otherwise, the phone works great on T-mobile (I use a 930F rooted on t-mobile and have never lacked signal where my wife's Iphone 7 or 930T had a signal)
Can I ask a question to you nice folks who've replied... This "upgrade" from a T-Mobile branded G935T to international G935F is going to cost me about $100 usd give or take... The sole purpose is for real root access... Is it worth it? Or should I just wait and jump on a newer device?
The reviews of the S8 are great, but over all it seems more like a skin change than anything else (besides the screen of course)

Unlocked Sprint LG G6 on ATT? Help!

I have an opportunity to buy an Unlocked Sprint LG G6 for a great price. The only issue I am on the ATT network. Would it work flawlessly on the ATT network if it's unlocked?
The Sprint model LS993 supports the same AT&T bands that the AT&T model H871 does. Neither model supports LTE B17 or B130.
So it should work.
You might never be able to get VoLTE or HD Voice working, since AT&T does it in a nonstandard way, but if that doesn't bother you, go for it.
