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.
So, can anyone on T-Mobile US, running TEKHD's TEKXnesis HYBRID and T-Mobile CSC, tell me if VoLTE works on the International S7/S7E with this special combo?
It's great that TEKHD can get a SnapDragon CSC into an Exynos ROM. Would love to hear people's experience wrt to T-Mobile US features.

Im still trying to figure out how to get it to work, it drops from 4g lte to 4g when i make a call
NM. He responded to my question on his thread.
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.
Hi all,
I lived in the US but recently came back to the UK. I got an unlocked S8 (SM-G950UZBAXAA) and I was wondering if I can change the CSC to BTU from XAA, since I haven´t got Spay to work
Cheers

Cheers mate. Looks like I cannot switch my carrier due to the different radio...

What do you mean?
The SD Galaxy s8s radios support every single band they use in the uk....

oh, maybe I got the name wrong. I mean that since my phone is G950U I can only use CSCs that are available for that model. THE BTU or XEU is only available for model G950F, so I cannot get them on my phone. Is that right?

So that may be true (although I'm not completely positive you couldn't ) that they do not make CSCs for you device on those networks, but a CSC is not necessary to use an unlocked phone on a different network. I have been travelling overseas with tri and quad and phones for years and the phone works just fine with a local sim in it. The CSC just makes your phone have local BRANDING and some configurations that the carrier wants. The radios all work everywhere. This may mean that you will have to do extra work to get custom carrier specific apps and stuff (like Verizon in the us has a visual voicemail app that many people who rooted have worked hard to get back) but the phone will make and receive calls just fine.
Think of it this way, many people in the carrier switch thread have made their us snapdragon devices XAA CSC which is unbranded us generic, and they all can make and receive calls just fine. The point of sim unlocked phones is that they can be used anywhere the radios can pick up signal, and yours supports every uk 3g utms and lte signal your country uses.
Maybe someday I will prove this completely by flashing an exynos CSC on my g950u and show it doesn't brick or even fail. Might put this misinformation to bed.

Thanks for your post, quite informative. The reason why I want to change the CSC is mainly for samsung pay, which seems to be limited to us cards on this phone. Other than that, everything works great, and it is not a big concern, I think I will just forget about samsung pay and use android pay instead (althoug it would be good to be able to get some of the promotions available, so I may pop up to a samsung store and ask if it is possible to switch)

If you are staying not rooted and stock there may be a way to do that without CSC change I don't know I haven't looked into it
I'll stick to the "official" set up for now, but I'll keep an eye in case it can be done in the future. Too much information for me! Maybe when root is finally achieved it will be possible, who knows
I’m from the UK and want to buy a Samsung s7 edge from eBay to give as a gift to someone in Pakistan. How do I make sure the Phone I buy will also work there as I think these are European models? Is it just any S7 edge with a G935F model number?
Thanks in advance, really would appreciate some help as I don’t want to make a £400 mistake. Thanks
Pakistan will support the G935F. The person that you are gifting may need to change the CSC / firmware of the phone to have features such as Video over LTE, Voice over wifi or Voice over LTE working, depending on where the phone is from and therefore its firmware/csc. This can easily be changed through Odin and does not trip the knox e-fuse (what voids your warranty and stops Samsung pay from working).
What is CSC? it stands for "country specific code" and is responsible for the set of features a phone provides based on its country and sometimes carrier within country. Different carriers within a country may have different codes for different feature sets.
3G and lower calling will work fine. 4G for internet should work fine, they should be always enabled regardless of CSC.
Hope this helps. Any questions, let me know.
