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.

Fair enough.
You still get your updates when you have the AT&T sim in the phone.
I do not have AT&T service at all and am totally unable to get any updates.

I am in Canada with my Rogers sim installed and received the latest update from AT&T on Friday last week. I have received multiple updates from AT&T when in Canada with my Rogers sim installed since getting this phone.

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.
how do i flash the tmboile firmware to my at&t s7 edge.. i have a att s7 edge and want to flash tmobile firmware to it and use on tmobile with wifi calling and the works.....any links with instructions and firmware. thanks

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.

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!

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.
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.

How do you sim unlock the phone first?
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.
If I buy used T-Mobile can I Flash AT&T firmware on it so I will have AT&T Enhanced Messaging and Wifi Calling Just as if it was an ATT phone????? Thanks
If the phone is network unlocked in theory the sim it sees when you first boot from setup it should then download all the carrier software and features. There is only one carrier U firmware so there isn't specific AT&T, T-Mobile. Now if AT&T tracks their IMEI's that were meant to be on their network then that may be where this all falls apart and some features may not come over then.
At least that is how it has worked in the past. Someone else feel free to correct me if I am wrong.

I saw a report on the forums here where someone flashed the att userdata and wiped and all of the carrier features worked.
I know on the 9/9+, even with the BOYD firmware, or flashing att bloat would not make a NON-ATT purchased device have advanced messaging /wifi calling / VoLTE. The trick was to activate that stuff on an att branded phone and then swap the sim.
It was very much a YMMV.
Similar issue here. My problem is i bought a s10 plus AT&T and it was supposed to be unlocked, however it wasn't the case. Mine is still AT&T locked and when i called them about my issue they said i would have to get service with them for a few months then i could end the service by paying the cancellation fee. I could then unlock the device. They also told me that my phone has an unpaid balance that would have to be paid prior to starting service. I have tried to contact the seller but to no avail. Anyways, my question is can I flash T-Mobile stock firmware to this phone and use it on T-Mobile?
