Anyone happen to know if the T-Mobile version of the S7 Edge will work perfect on ATT network? I have a current pre-order for the ATT variant but remembering that my Note 4 on ATT was never completely root-able because ATT sucks about those things... I thought maybe I should/could buy the TMobile version and just use it on ATT .... Thoughts?

It has the radio bands to support it but AT&T will not allow non AT&T branded devices to use VoLTE.

So if I buy the T-Mobile variant it will work on AT&T network just not able to use the VoLTE capability of AT&T or T-Mobile (In my area AT&T has the best coverage so I can't switch networks)?

What I've read is that physically the phone supports all 4 major US carriers but each carrier version is firmware locked to that carrier so maybe not.
I personally used u firmware on my att but I really need the WiFi calling that's why I decided to come back to att firmware, but someone said that the t-mobile firmware can be flashed as well since both fw are on same BL now , I did flashed the t-mobile fw for some reason on this firmware I get full LTE bars in most of the places for example in my house with att I got only 1-2bars LTE the speed 4-7mb per second, and with t-mobile I get full 5 bars speed up to 60mb per second now I don't even need the WiFi calling anymore since I have signal in most places and the battery last around one hour longer a day

I use the AT&T service on a tmobile phone. It works great. If you want you can flash the AT&T firmware on it as well. I actually prefer the Tmobile firmware, it's faster and gets better battery life.
On the Tmobile firmware the only thing you lose is WifiCalling. VOLTE works great and I actually get better data speeds on this device than my AT&T devices.
I've been combing the forums and I'm still unclear on a few things and looking for help. Current AT&T customer and I plan to switch to T-Mobile soon. Any confirmation or corrections/answers to the questions/statements below would be really appreciated.
1. The 935F variant is the international model that works with all GSM carriers (and I assume without any carrier bloatware) but VoLTE and wifi calling will not work on any GSM carrier here in the US. Theres a secondary 935F model (d?)- whats the advantage there? Shopping tools that let you compare the models show no difference but always priced differently. There is something I'm missing.
2. The 935U variant is official US unlocked model for use with any carrier. Only silver. I have not seen any posts confirming that VoLTE and wifi calling works- and will continue to work if you switch carriers.
3. Lots of listings for factory unlocked 935A variants. Official AT&T version. That just means a reseller has applied unlock codes to each and resells them? I'm very unclear here. Listings always say compatible with all GSM carriers. But will AT&T bloatware, logo continue to survive? And again, will VoLTE and wifi calling work and continue to work if I switch carriers. This is also the cheapest phone to buy virtually new. But if truly GSM compatible with features that are important to me are intact among carriers- what would I get for the significant premium to get the 935U? Besides, I wanted black.
4. Black Pearl- has this been released in the US and in any specific model? I have not seen one.
Thanks in advance. Really appreciate it.
FD is dual sim. You can put 2 GSM simcards there and both are active. Can send and receive sms or calls.

You can install 935U stock firmware on att/tmobile/verizon version. If used on tmobile network, you will get wifi call and volte. For att you have to install or have att stock.

1. 935F is the European / International model. 935FD, D stands for Dual-SIM, both slots will be able to accept a GSM SIM card and are usually used, as one for work, and one as a personal number. Dual-SIM however, is not a popular concept in the US.
2. Check the 935U threads, if a CSC flash is possible, it might work. Though, I'm not sure.
3. Yes, if you have an AT&T phone, it'll still have the AT&T ROM, which will always remain the same, regardless. It will work with other carriers, meaning SMS, Data and calls are compatible, but things like VoLTE and WiFi calling might not work on the carrier that the phone isn't intended for.
4. No it hasn't. It's been released in South Korea with 128GB of internal storage. Also available in the UAE, India and some other Middle Eastern countries. Only in a Dual SIM Configuration (SM-G935FD), and with 128GB of internal storage. It's a limited edition phone, and not sure if it'll be launched in the US.

A couple of followups if thats ok:
1. So if I purchase a "factory unlocked" 935A, before I insert any SIM, I can immediately flash the 935U firmware and it will remain unlocked? I couldn't find a single post that said VoLTE or Wifi calling worked with the 935U firmware on T-mobile (AT&T- what do you have to install?)
2. Flashing to firmware is not considered rooting the device? My work will not let my device connect to the network if it is rooted.
Seems like there is no reason to spend the extra money for the 935U variant. I can save hundreds and purchase an unlocked 935A and flash the firmware. I've rooted devices before and the process looks similar.
Thanks.

According to other people in verizon 935u thread and att 935u thread, volte and wifi call works on tmobile. For att wifi call and volte, it must be a ATT carrier firmware. ATT only let their branded phones have wifi call and volte while tmobile allows any phone to do this. That's why with 935U wifi call and volte will work fine on tmobile.
Every time you insert a new sim the phone will adjust settings, so there's no relation with what you can install.
Flashing is done through Odin while phone is in Download mode. There no root involved.
I am considering upgrading to the S8. I like that the G950F has an unlocked bootloader on a phone that has (almost) everything I want.
But it seems like it's a bit of a hassle to get it to work fully on the T-Mobile network. It looks like I can flash the CSC to enable WiFi Calling and VoLTE on it, but is there any hope for 256QAM and 4x4 MIMO? There's hardly any information about this other than one or two threads. So I'd like to know:
If I go with the G950F over the T-Mobile or Unlocked US variants, what am I missing out on out of the box?
What will flashing the T-Mobile CSC not fix? (I currently think it does fix WiFi Calling and VoLTE.)
Can I flash the T-Mobile US modem on the G950F to fix this, or will that just brick my device? (Snapdragon image on Exynos terrifies me.)
Am I missing some other way (like a secret service mode or something) that would allow me to force 256QAM and/or 4x4 MIMO on the G950F?
I really hate that I can't just have a US model with an unlocked bootloader...
I think Galaxy S8 International variant maybe missing some bands and I would suggest you either get T-Mobile as you mentioned or US unlocked. With US unlocked which I already ordered from Samsung, should support all T-Mobile features: VoLTE, Band 12 and WiFi Calling. At the moment Samsung offers $200 off if you trade in any Android or iOS device. Just check their page for Trade-in details.

Hmm, I don't remember which bands exactly and how many, but F model had some bands missing for T-Mobile.
Just one night frequency
The exynos variant lacks 4x4 mimo and 256qam from what I've read. It achieves 1gb down via 5xCA. But also only allows it to max upload at 150mb/s
So it would only be able to utilize the 3xCA from tmobile. And not get max possible downloads. But the F does support all 3 of t-mobile's used bands

Got it. That's what I was looking for, thanks. My understanding is that it's a hardware issue that can't easily be fixed via service mode or flashing something, but it doesn't look like I'd miss out on much overall.
I am in a 4x4 MIMO service area though so maybe I'll just hold out for now and see what happens over the next few weeks/months.
Can someone point me to the thread for how to make a sm-g950f have volte and wifi calling on T-Mobile?
My searches turned up nothing concrete if this is possible but I found a Note 8 thread that sounded promising.
Does anyone know if I were to flash the latest Germany T-Mobile firmware (DTM) from Sammobile, would that enable VoLTE, WiFi Calling here in the US?
Currently my G950F S8 has the Australian (XSA) firmware installed and it doesn't have VoLTE or WiFi Calling. The WiFi Calling setting in Quicktiles is greyed out.
I purchased a refurbished Verizon S7 Edge. Looks brand new, never used... seems flawless in every way.
Put my Cricket Sim in it and got Cricket to register the IMEI number.
Aside from the irritating message that I'm not using a Verizon Sim, and all of the unwanted Verizon bloatware... the phone will NOT stay locked on the AT&T Network... AND, it has to be Manually Connected to the AT&T Network every time, in order to get 4G LTE.
Otherwise, I only get H+ and the phone constantly wants to switch to Global Network.
So.... I started reading through an endless number of posts. I found what seemed like many good answers, but to be honest, I'm not sure if they're still relevant or if the steps, choice of software tools, etc. have changed.
More over, I am not a cell person, so this all seems like Greek to me... actually, I can recognize Greek as Greek, so this is worse than that. LOL
I'm looking for some spot-on knowledgeable person who can walk me through the steps dealing with whatever Rooting, Bootloading, Flashing, etc. are, and getting to the point that perhaps my Verizon S7e now thinks that it is either an AT&T S7e... or that it's so Universal that every band is made available on here. I'm sure there's some Firmware somewhere for that, because I swear I read about something like that on here... but can't locate that thread now.
I understand that this is a big ask... and, if there are threads with step-by-step directions for newbs & dummies, then a list of those threads, with the order in which to complete the thread-posted directions, would really make me extremely happy.
Also, I'm curious if taking this approach to this phone can improve the cell signal reception. I've noticed with my ZTE Axon 7 that ZTE updates on at least 3 occasions have very noticeably degraded the Axon 7's signal reception. I thought I was imagining it and blamed it on everything except the phone... until reading endless complaints from other owners, about the same issue, and discovering that many of those owners seem to be much more knowledgeable about cell phone hardware, software, firmware, etc., than I am.
So, I'm hoping that I can discover exactly what I need to do to make this Verizon S7e run like a Derby Champion!
I'm sure there is someone out there who has the exact same issue and quest... and if so, I'm hoping that he or she will come forward and assist, especially if they can empathize with my frustration and learning curve! LOL
Thank you, in advance, to anyone and everyone who can help me NOT BRICK my phone and turn it into a truly useful tool.

First you need to check AT&T and the Verizon S7 and make sure the phone supports the LTE bands for AT&T. You will also need to flash the Unlocked software for the SM-G935U model. https://www.sammobile.com/firmwares/galaxy-s7-edge/SM-G935U/ATT/
<<First you need to check AT&T and the Verizon S7 and make sure the phone supports the LTE bands for AT&T. You will also need to flash the Unlocked software for the SM-G935U model. >>
I'm in the same boat and appreciate your link to the SM-G935U firmware for AT&T.
I see in your link to the SM-G935U firmware that the dropdown menu includes a reference to AIO firmware. Is that Cricket firmware (the APN for Cricket includes a reference to aiowireless.net)? With a SM-G935V, can we use any of the flavors of SM-G935U firmware?
Thanks!

You should use the firmware that best supports the network you will be using. This will make life a lot easier with little to no workarounds needed to make things work.
Thanks & I'm starting to work on it now

Thanks for the information. This site can be overwhelming to a newbie... especially when I'm trying to work on my ZTE Axon 7 (already on Cricket, but bought the S7e as a replacement) and failing at that for some reason... plus get this new refurb S7e stripped of the Verizon firmware, etc.
Yes, it already has the bands, even with Verizon firmware, for the AT&T 4G LTE... but because of the Verizon software (or so I suspect) it requires me to keep manually connecting the phone to the AT&T 4G network (search, connect, etc.) whenever it drops or the phone is powered off. That's when I came back here to read and research.
Hopefully, I'll better understand all of this after I've successfully completed rooting and flashing one or both of my phones and one of them is working better for me on the Cricket network!
I'll post again if there are questions or successes... and I'm checking back on Judicata's progress as well. Similar problems might have similar solutions

I switched back and forth a few times... it looks like it's the exact same firmware update names. All of the reading I've done on XDA Dev always seems to tell people to load ATT. I think I also saw something about being able to unlock every bandwidth in the phone... that these phones are capable of accessing all carrier bandwidths and are only limited by the software on them.
I'm also trying to work on my ZTE Axon 7... so I might be confusing those posts with the SG S7e posts. LOL

I installed the SM-G735U software on my SM-G735V Verizon S7 Edge this afternoon. I used the AIO version figuring it was for Cricket, which is my carrier.
So far so good. The APN settings were all there and correct for Cricket. I wasn't sure whether to tick Re-Partition or not. I ticked it, and all worked out. I have not yet put the phone into Recovery Mode to wipe the cache then wipe data/factory reset. as suggested in the instructions on Sammobile to get updates OTA.
I'll post if any problems crop up.
Reflash stock bootloader after rooting. You get near stock performance.
how to root my phone
I have s7 edge verizon G935V with androd Oreo so if I install G935U firmware all verizon stuff would disapeir? could I rooted later? or how can root it?
Hi,
I see Samsung has sales on S8+ from US Cellular for less than the one from ATT.
If I buy the US Cellular one and insert my ATT SIM, it should rebrand it as an ATT phone right?
At that point, will it work and behave just like an ATT phone or will ATT block/prevent the stuff like VoLTE/HD voice/visual VM etc as it is not a true ATT branded phone?
thanks
It is unlikely to work that way. After you purchase you will need to have US Cellular unlock the phone. If buy it outright, they may do that but you will want to check with them first. If you buy it unlocked as mentioned in the title it should be ok.
Once the phone is unlocked there is no reason it wouldn't work on AT&T, but it will not rebrand itself. You will need to load AT&T branded firmware on it to take advantage of VoLTE.

Are you sure? From what I've read 1) US Cellular phones after a certain date come unlocked (forget the exact date but it was before the S8+, so nearly certain it is unlocked) 2) the US S8/S8+ will rebrand based on the inserted sim (from the galaxy s8 reddit PSA announcement old.reddit.com/r/GalaxyS8/comments/7jdcno/psa_with_the_latest_us_carrier_updates_your_phone/ )
So it will brand and push ATT firmware
That's why I was asking specifically if things like VoLTE would work in case someone else has done this. It seems ATT is more restrictive about allowing certain features than other carriers

That may be true of US Cellular, they do seem to be pretty customer friendly. I had interpreted that the device will configure the hardware to operate on whatever carrier's SIM is in, but not the firmware. However, I have not tried this with mine. I do have a branded S8 that I have put unlocked firmware on and it stays on that firmware.
If the phone is not carrier locked and you put an AT&T sim in it, then it should work on the AT&T network. You will NOT get VoLTE/HD calling or Wi-Fi calling. Regular calling and LTE+ data will work fine.
It will not automatically download the AT&T firmware and become an AT&T branded phone.
I do not know what will happen if you put the AT&T firmware on it. I asked if anybody had switched to the AT&T firmware and gotten VoLTE or wifi calling, but did not receive any answers.
I have an unbranded phone on AT&T. I've not gone through the trouble of switching to the AT&T firmware.

I have not tried. Other than VoLTE and wifi-calling the phone works perfectly, and I've never had to reset it, so I've not bothered to try and change firmware.
