Hey everyone,
I have an ATT S7 Edge and was looking to switch to Tmobile. My S7E is unlocked with a Prepaid Tmobile sim in it now and all is working well (even VoLTE which I was shocked about). I'd like to have Tmobile software for wifi calling if it is at all possible. It seems as if VoLTE compatible so I figured the hardware was the same, just different software/basebands. I know Samsung is a nightmare with their carrier versions/locked bootloaders so I assume the chances of this being possible is unlikely, but I figured I should at least ask.
You won't be able to flash TMo firmware on your AT&T phone. Sorry.

Well.. he could at least try to flash the T-Mobile US firmware... worse it could do is fail to install, right?

I think worst case scenario is he bricks his phone.
Trade it on CL for a tmobile one.

A Verizon s7e is not the same and will not work properly on tmobile service.

DO NOT do that.If you do so then you can flash your framework back to ATT. I flashed my g935p with g935t framework afterward I can't go back to Sprint framework.
I'm trying to convert my T-Mobile to AT&T because volte isn't working right now. Did you have any luck going from ATT to Tmo?

Were you able to figure this out? I read SOMEWHERE that it's definitely doable but now I can't find the post with instructions.

T-MOBILE S7 Edge works on Verizon, ATT with unlocked Sim card! I also have LTE on All 3 Networks.
First question is how did you get your phone unlocked? I thought tmobile made you wait 45 days before they would unlock the phone

A lot of times if the phone is paid off, it'll unlock as long as it meets 1 requirement.
Sweet Verizon is super fast and coverage is virtually anywhere.

Verizon uses a lte sim card for data only. There will not be(shouldnt be anyway) any call support because the 935t does not have cdma, unless verizon is using different bands on newer devices like tmobile(band 12 - 700a)

how did you get sm-g935t to work in verizon please help me i have my s7 edge unlocked from t-mobile and i am trying to used it on verizon
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.

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!

I just got rid of my AT&T edge and got a tmobile one, I wasnt about to go to best buy and get updates all the time like I was told by samsung
You need an AT&T sim it doesn't have to be activated. Im using mine on cricket and got my latest OTA by putting my deactivated AT&T sim and using my wifi to download. I did have to check twice and reboot once to trigger the update. If you change the time in settings up a day you don't have to wait 24hrs to recheck for update.

I have an unlocked AT&T S7 Edge and use it both on Rogers and AT&T, I simply change the SIM depending on where I am. The updates still come from AT&T regardless of where I check for them.

I have been unable to get even one update on 4 phones with a Cricket Wireless SIM in.
I dont understand it, AT&T Owns Cricket, you would think it should work without any issues.
I have a very interesting question regarding on using tee 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. 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?
If you flash the U firmware, you'll get wifi calling, VoLTE, and OTA updates. There is a thread in one of the other AT&T forums that has instructions.

You could also go another route and flash the t-mobile firmware on the at&t variant, it works quite well and is the equivalent of the U firmware with t-mobile account management, voice mail, and features.
I have s7edge at&t ..it don't have any volte option
I want to enable volte option. On my mobile
If i flash sm-935U on my at&t will it activate VOLTE OPTION
If you switched to TMobile just ODIN the Tmobile Firmware and you will get the updates OTA.

Yeah you do, its under Connections/Mobile Networks/Mobile Data its called Enhanced LTE services....I actually shut mine off and its saving quite a bit of battery it seems and I havent even noticed a difference in phone call quality, seems kind of useless
you need to get or buy a Gophone simcard or buy a gophone (comes with Gophone simcard), just activate the gophone simcard, you dont need to pay money on it. i never able to get att software update using Cricket simcard but when i put a activated gophone simcard (no need to pay money on it), it lets me update to the latest att firmware ! funny, how gophone and cricket are owned by parent company att but gophone lets me update and cricket can NOT.
I have a chance to get a AT&T S7 Edge from someone cheap. Can I use it with Sprint if I flash a stock Sprint Fw on it? Didn't know if Sprint's system would recognize its IMEI # or not
You might need to ask in the Spring Forums or call Sprint. I know the ATT phone does have to SIM unlocked. I am pretty sure you can use it. I am using the TMobile FW with ATT.

Ok thought so. Does the Imei number of the phone change when flashing another fw? Or no
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

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.

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.
