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.

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.

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 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.
Hi, I wanted to know whether an unlocked AT&T branded S7E would work on Verizon without flashing the U/V firmware, despite missing band 13. As in, would Verizon approve the IMEI and send in the SIM card because I do not currently have a Verizon SIM and am planning to join their unlimited plan. Thanks
Try it and report back. IM still waiting on my unlock code to come
It will not work with Verizon. Only unlocked phones the except are Google devices and iPhones

Why do you speak of things you don't know about? This is 2017. Most Samsung and iPhones are the same model through every carrier now aside from using carrier specific firmware to lockout certain bands. Right now I am using an att S7 edge flashed with Verizon firmware . But of course you have to sim unlock it first before using on the network. I've been using it for the past week and everything works great. Thank you kindly.

This has been discussed before but I'm still not 100% clear.
Can I buy an unlocked Galaxy s8 plus that comes from a different carrier (say Sprint) and flash the AT&T firmware to it, changing the carrier identity so that you get features like wifi calling and VoLTE?
Thanks!

Yes you could get it working with wifi calling and voice over LTE no problem but you got to make sure that if you get a phone like from Sprint/Verizon / T-Mobile unlocked before trying to carrier switching

Thanks for replying. So make sure I have this right.
If I purchase a Verizon/Tmo/sprint Galaxy s8 plus and put my AT&T sim in it and it activates on the network and allows me to make/take phone calls then I can assume that the device is unlocked. If it's carrier locked that should not work.
Yes that is correct but if you want to have all the AT&T features you must carrier switch following instructions here on XDA which will convert your Verizon/ Sprint S8 phone and to a completely AT&T phone

Riddle me this. I have a guy trying to trade me an S8+ att version for my OP5. He says it is unlocked. Can I flash unlocked firmware on it to get rid of any bloat and all the att stuff in the background that will be taking my data?
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.
