Got a question, would this phone work on ATT. The bands are compatible right ? People are selling unlock codes do you guys think it will work on the network ?

Yes and no.
Any T-Mobile phone, and vice versa AT&T to T-Mobile, will work on each other's respective networks to some degree. AT&T and T-Mobile's 3G/4G bands are NOT compatible.
However, you will still get EDGE, so technically the phone will work if you only use it as a phone.
Apologies if this has been covered, or if this is the wrong place to post--I've searched and have been unsuccessful in finding an answer so I figured I'd ask myself.
Is the G935FD (Samsung Galaxy S7 Edge Duo dual sim) variant fully compatible with AT&T? That is, will it work with enough LTE bands such that I should expect fast enough data throughput? I know that it wont be able to access all AT&T LTE bands, but for practical purposes, will this phone work? It seems to be selling relatively cheaply on eBay, so before pulling the trigger I figured I would just double check that it will work. I don't care so much about having multiple sim cards, I mostly just want a cheap(er) phone.
I'm fairly convinced that the G935F will work based on a few other threads I came across on XDA and Reddit. Just looking for confirmation that the G935FD works and works well. Anyone have experience to share here?
Cheers and thanks in advance.
I have two international G935F's, one G935FD and one G935F, both on AT&T. Also an AT&T S6. I haven't had any issue with LTE. All give comparable speedtest results and all are using LTE Band 2 in my area (SF Bay area). I think they may be missing Band 30 but I don't know where that is used. The app LTE Discovery will show what band you are using. Things that don't work on the international phones for me are AT&T HDVoice (VoLTE) and AT&T Video calling. I also believe that if AT&T ever offers Voice over WiFi, that won't work either. These weren't issues for me. I was not expecting Samsung Pay to work but was surprised that it worked on the G935FD. Further investigation revealed that it was the CSC and image. I was able to download different images and got it working on the G935F as well. There's a thread on Samsung Pay on Int'l phones that discusses this if it matters to you. I think when you buy an international phone (G935F/FD) you don't know what CSC you'll get. I don't think the seller can tell without going thru setup and running a utility (I used Phone Info) to reveal the CSC/image. Everything else seems to work the same as the AT&T-branded versions.
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 bought a Verizon SM-G950UZKAVZW direct from Samsung. I thought that I was buying a phone that I could take to any carrier. I'm hearing that might not be true. Does anyone have definitive, confirmed specs ie supported radio bands on all of the carrier variants as well as the upcoming intl version? Also I heard other reports that the hardware is identical and it's firmware that is limiting the phones. Not sure if that is true either. Samsung was absolutely not helpful.
Bottom line I need to know:
1 if I keep the SM-G950UZKAVZW, will I be able to use it with other carrier networks?
2 if I can use the SM-G950UZKAVZW with other carriers, what actions (if any) would I need to take to do that? (Other than swapping a sim card)
3 would the phone I currently possess be limited in any way if I were to use it with other carriers? (Limited is defined here as "performing differently in contrast to that carriers native S8 model variant") if so, specifically how would it be limited?
4 if I were to purchase an unlocked international model once it becomes available, would that phone be limited in any way when used on any US carrier? (Limited is again defined here as "performing differently in contrast to that carriers native S8 model variant") if so, specifically how?
If you aren't sure, please don't reply. There's plenty of people documenting their best guess already. I'm looking for the straight story.
Thanks for reading!
All of Verizon phones are Sim card unlocked and since there is really only 1 version of the S8/S8+ in the US (with different model #'s corresponding to the different carriers) using the phone on another carriers network is not going to be an issue. All you need to do is insert the sim card in.
http://www.gottabemobile.com/how-to-unlock-the-galaxy-s8/
As a quick note, if you have a Verizon Galaxy S8 congratulations. Your phone is already unlocked. Verizon Wireless no longer locks phones, regardless of what you might hear from friends or family. Simply drop a T-Mobile or AT&T SIM card in a Verizon model and it works. It may require manually configuring the APN settings though, so keep that in mind.

The ONLY exception that might be would be Sprint since they are CDMA as well, but who really wants to go from Verizon to Sprint?????
All 4 Major US(and subsequent sub carriers) are receiving the same version of the phone(meaning same internals). From my understanding, inserting the carriers Sim card into the verizon phone just means you start going at that point and have access to all the carriers bands
If you got an international version, it most likely would be powered by an Exynos CPU vs the Snapdragon 835 so there would be some performance differences (typically Exynos models perform marginally better based on previous history)
If you're looking for a US unlocked model - wait until next month
http://www.theverge.com/circuitbrea...-unlocked-galaxy-s8-plus-pricing-release-date
I appreciate your clear response! Would it be accurate to say that I will have just as much freedom to hop from one carrier to another using the phone I have, as opposed to purchasing the upcoming US unlocked variant?
Also, I have heard the same thing about the hardware, that all of the carrier variants are the same physical model. But some folks, including the Samsung tech support rep I spoke to (unfortunately that probably doesn't mean a whole lot) seem to think that the carrier firmware is limiting the radio bands. Do you know this to be false?
I have the Verizon version and works fine on Tmo out of the box. Have to use Verizon update software through Windows though. OTA's will never come through.
I am using Verizon GS8 on att, it works but I only get HSPA mostly. No LTE, so band is definitely capped by firmware.
I didn't have any issue receiving ota with att sim in vzw gs8
I saw a review that said the s8 gets locked to the first carrier sim it accepts. Can someone confirm swapping sims of different carriers works?

Have you tried going into the network band menu and locking it to one of the AT&T LTE bands?
This still works on the S8 (found this on the S7 and used it to lock my S7 to band 4 for Tmobile)

You'll need to wait unti the official AT&T rom is available from Smasung and then you should be able to flash it via ODIN onto the phone and get all the AT&T carrier bands

Once it becomes available? You can buy Exynos right now from other countries. Clove in UK will region unlock the phone before shipping to you in the U.S. What needs to become available?
Don't confuse the "unlocked" S8 Samsung will sell here in the U.S. in a month or so with the Exynos international variant. The "unlocked" S8 coming to the U.S. is still the bootloader locked Snapdragon version, just without carrier branding. It will be carrier unlocked but not bootloader unlocked. If you care about rooting, TWRP, ROMs, etc Exynos is what you want.
would that (Exynos international variant) phone be limited in any way when used on any US carrier?

NO, except if you are on CDMA-handicapped Sprint or Verizon. If you use Sprint or Verizon be aware Exynos doesn't have 3G CDMA bands to fall back on if you can't get LTE. For AT&T or T-Mobile, YES it has all the LTE/HSPA/GSM bands.
The "international" Exynos variant can be bootloader unlocked, rooted, etc. so tons of advantages. While it has Verizon LTE bands, there's no CDMA. This means you really need Verizon VoLTE to work and I don't have the answer to that. And if you can't get LTE signal on mobile network, you won't have any signal due to no CDMA fallback. Again, only an issue because of CDMA if you stay on Verizon instead of using AT&T or T-mobile (or their network affiliates). You seem like you want to switch to another carrier? So, go ahead and do so!
EXYNOS VARIANTS LTE BANDS:
LTE Bands: FDD: B1(2100), B2(1900), B3(1800), B4(AWS), B5(850), B7(2600), B8(900), B12(700), B13(700), B17(700), B18(800), B19(800), B20(800), B25(1900), B26(800), B28(700), B32(1500), B66(AWS- 3) | TDD: B38(2600), B39(1900), B40(2300), B41(2500)

Yeah I screwed up. I did confuse them.
I'm not interested in all that rooting stuff I just want a phone that pretty much works anywhere I want to take it and if it's slower on one network than another I wanna know what I'm getting myself into.

Hey guys
I'm from Brazil and I wanna buy the Verizon's S8 but I'm afraid about the 4G.
I saw that this model has the Brazil LTE frequencies, but I read here that Verizon capped the band from the firmware.
Somebody knows if I could flash via ODIN the unlocked rom that will come with the unlocked version in USA and so get the LTE free to use in any place?
I don't want to assume the risk to have a top mobile phone but don't be able to use 4G.
Thank you very much guys
Hey mredamon. Did you ever get a clear response here or somewhere else about this?
Hi all,
Been through a few thread but didn't get a definite answer as I would like to flash my VZ s7 edge to be on T-mobile as I don't mind the carrier float wares. I just want it to work as the phone is bought from T-mobile. I know it's possible but does everything work including unlocked the T-mobile LTE band? Wifi calling or VoLTE etc.. I wasn't sure if the software will unlocked the bands or is it restricted to hardware limitation. Would you recommend the U firmware or T-mobile? I am trying to give the phone to my nephew as he's a poor college kid using S3 and he's on T-mobile. TIA.
Yes it works. Just make sure you flash T-Mobile firmware
If you flash the U firmware for the S7 Edge, its modem should have all bands available as well.
You might just have to root it and make some adjustments to the CSC.
