It doesn't support it. IMEI not recognized in AT&T's system. I am pretty sure there is no AT&T stuff baked into the US Unlocked version like the HTC 10 had. The software seems to be the same as the dual SIM international variant with the same bands.

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.
Just moved and tmobile service is horrible here. I have to switch to verizon. I got my tmobile s7 unlocked and have heard different feedback as to whether or not it will work with verizon. Some say yes, some no, and others have said it will but not with 3g signals.
Anyone know the truth?
I am almost positive the T-Mobile (and AT&T) versions do not have the CDMA radios enabled, and Verizon (and Sprint) need CDMA.

Well you're almost positive because you've never tried it lol which is a negative. Just flash the unlocked US firmware.
How to enable the cdma? Can I root it and flash a Verizon firmware?

you have to flash the SM-G935U over the SM-G935T. And that should take care of the problem. Just make sure that you unlock your phone via the t mobile unlock app. otherwise you wont be able to use other carriers signal.
here is a link where you can get it the SM-G935U
https://samsung-firmware.org/model/SM-G935U/
So by flashing the verizon firmware on an unlocked tmobile s7 edge, you should be able to use it on verizon?
Thanks!

Absolutely not, it will NOT work but if it was the other way around
and you wanted a verizon s7 edge phone and use an at&T or
t-mobile sim then it would work. The verizon s7 edge has a sim
slot which is not used if it's on the verizon network.
All S7 Edge Verzion phones are sim unlocked.
Good luck, have a great day!
Thank you for the help!

is there a step by step process to unlock and setup/flash/install phone completely to be able to use with Verizon?

Hi guys.
Will I have any band issues if I get the phone unlocked from LG?
Does it have all of the LTE bands for AT&T?
What about getting a t mobile V20 and using it on AT&T?
Thank you.
Probably. I am using a verizon v20 on my tmo sim and it never gets LTE. Just H+. Its a crap phone in that regard.

Use this. I recently discovered the site and it has helped me a ton.

The unlocked V20 (US996) will work on ATT, even though it does not have ALL the bands. I have one on ATT right now and don't have any issues. The missing bands are for newer frequencies being added to support capacity. I live in a metropolitan area so I have good base support. Check this link for details. https://www.frequencycheck.com/models/AzWoD/lg-us996-v20-lte-a

To each his/her own. Reading papashex's words is what finally convinced me to get this particular version.
It has the same bands as my S4. US996 is missing Band 33 I believe, well so is my S4. I think I'll be fine.
I've searched and cant find anything but the bands for either service. Which they use a lot of the same. Is a T-Mobile branded S8 usable on Verizon? Full 4G or not? Thanks!
its a gsm device. i believe the internet data part will work but not phone calls

Darn. I was hoping since they all have the same model number that it would be possible.

Call Verizon with your IMEI # and they can check if it's compatible with their network.

Did you ever figure out if this was possible? I can't seem to find a definitive answer.
Bump - anyone know if this will work?
As soon as I get mine unlocked I'll let you know as I have Verizon. All s8 models are the same but I'm sure the T-Mobile software has blocked Verizon bands. I'm sure if you flash Verizon software it will work just fine.
I have an unlocked T-Mobile Galaxy S8+ and it does not work on Verizon. I went into a Verizon store and they tried for an hour to activate the phone to no avail. They tried multiple different SIM cards and none of them worked. If anyone has better luck, please let me know. But they weren't able to figure it out at Verizon.

You need an unlocked Tmobile S8 or S8 plus.
Read the instruction in "Flash any carrier 100%" to flash to the carrier you desired, activate all bands.
Then use it on Verizon.
You need to flash your phone to Verizon to work. I did the exact opposite actually. I bought a Verizon device and flashed it fully to T-Mobile. Works perfect on T-Mobile because every US Galaxy S8 for the major carriers is SM-G950U. They support each other's bands, their just disabled by the carrier firmware.

Don't know about Digits because I don't use it, but Wi-Fi calling does work. I get the T-Mobile boot logo too.

I did not have any luck flashing it to the official Verizon Firmware, but I was able to flash it to the G955U1 firmware. The official unlocked US Firmware. Make sure your t mobile device is SIM unlocked by TMOBILE before you do this.
1. SIM unlock device by tmobile (pay off device, meet the 40 day requirement, etc).
2. Flash to G955U1 (S8+) or G950U1 (S8).
3. Insert Verizon SIM or ATT or any SIM.
4. Your phone will give you pop up warning saying it needs to restart to configure the new SIM.
5. Enjoy your new carrier.
Did you use a Verizon SIM and did you get both VoLTE and WiFi calling to work with the G955U1 FW?
my 2 cents

I went to Verizon store and used one of their Verizon SIMS from a display model of the S8+. Voice over LTE works, Data works and I was not able to test Wifi Calling at the store. I even ran a speed test and had about 27mpbs down and the associate ran speed test on his phone and he got about 20mpbs down connected to the same server using the Speedtest app. I ran the LTE discovery app and shows me connected to LTE Band 13.
Hope all of this helps.
Bringing S8 to sprint?
Did you anybody try to use a TMobile or other branded S8 on Sprint? The Sprint customer support is not able to add the IMEI to their database for whatever reason.
@Aephel
@T33H00
Silly question, but does doing all this void Warranty? or is there no such issue anymore?
For example flashing Verizon Firmware onto a Tmobile Unlocked.
I unlocked my t-mobile s8 plus and attempted to use a Verizon SIM. It does NOT work. Verizon states that the IMEI is not in there database and that they cannot activate it.
I am using a Sprint unlocked phone on AT&T and works perfectly. Last night I tried my friends Verizon SIM card and it read everything perfectly. It recognized his phone number, network state well. Does this mean I can use it on Verizon? But when I check the IMEI with Verizon it says incompatible! Any input?
My guess is they don't officially support it but since it supports the right lte bands it will work on 4g but maybe not 3g.... Out of curiosity because I may need to do the same thing in the future how did you get the Sprint V20 unlocked

I used a remote unlock service through ebay.
What version of the software did you have when you unlocked it ?
