G935F/G935FD on US T-Mobile -- VOLTE and Samsung Pay both possible? Just one? - Samsung Galaxy S7 Edge Questions and Answers

So I've been trying to piece together my options for firmware for the G935FD, to replace my G935T on T-Mobile in the US. There seem to be several fixes to get around the loss of certain services, but does anyone have a definitive answer currently on what firmware can address what?
It sounds like the Czech T-Mo firmware will get you VOLTE, but not sure about EVS (and probably not Samsung Pay?).
There are multiple firmware options that will allow Samsung Pay, it seems, with a lot of people having luck with the version for the United Arab Emirates. But I'm guessing no VOLTE?
I recall seeing where someone claimed to have flashed US T-Mo firmware and was able to keep all services, but I'm not sure how that's possible on the Exynos...
Is there a solution to allow both on T-Mo in the US? Wifi calling at all possible, or is that just a pipe dream? What about this other, recently announced EVS stuff? Can anyone point me in the right direction?

@Rydah805 can comment on Samsung pay (he's not rooted I believe), we're both on the latest build for Orange Spain (G935FXXU1APEK_G935FAMO1APEK_AMO). It also has wifi calling which seems to set up but I haven't managed to place a call on wifi yet...

Yeah, I'm not rooted and as @Remix22 said, on the latest Orange Spain firmware. Unfortunately I don't have my device on hand, I'm getting it swapped due to a gap between the glass and the side metal frame, but WiFi calling is present. I hadn't tested it out, I assumed it was working but it was reported it didn't do anything...? Anyways, I know Singapore is currently testing Samsung Pay but I don't have any clue if that CSC supports VoLTE and WiFi Calling.
I wish Samsung would follow the footsteps of other manufacturers and make one single setup and have it setup based on SIM. (They already do this actually with certain features... like "Identify unsaved numbers.")

IDK if anybody wants to test the latest CSC firmware from Brazil? I know they're also testing Samsung Pay. It has the latest build log: http://www.sammobile.com/firmwares/download/72867/G935FXXU1APER_G935FYTO1APER_ZTO/

So is Samsung Pay working well for you on the Spanish firmware? And do you know if you were able to get LTE data while on a phone call?

International Versions

Are all international versions of the Edge+ alike? Is there any one particular international version that should not be purchased because it will not work on a carrier or be rootable?
You have to rely on spec sheets and user reports. Versions C, F, and I are most likely candidates to work with GSM networks. Most other versions will probably work but with limitations (e.g. no LTE) I know that Note 4 SM-N910C works on AT&T network with full LTE compatibility. Dual-SIM variants are usually not fully compatible.
I wish there was a aggregate database stickied in the forum but it doesn't seem to materialize because XDA members are all over the globe. In any case I would inquire with members who have first-hand experiences.

What is the difference between 928c, 928f, and 928i?
I've seen 928c 32 gb for about $750 and 928i 64 gb for $1900???
Edit: ehh, I found the 928i 64 gb at $1049 too, which makes more sense given the space. Still though, which to use on AT&T in the USA?
AT&T S4 i337 > SafeRoot > SafeStrap 3.71 > HyperDrive RLS12
Tasker-ized
Would really like to know about this aswell
Specifically the G928i. Is this one bloatware free? I heard its from Australia but it does not specify which carrier. I already made the purchase, waiting for it to get here so there's no way back...
I thought the "i" stood for international, turns out the international version was the F.
Does anyone currently have the G928i in hand that could help me clear this things out?
Thanks
Hi ... I have the 928I as i'm now living in Australia and its with Telstra. There is bloat but looks like there wont be any custom roms from what I've read
I purchased the G928i and couldn't be happier. I had some Galaxy bloatware that comes with all S6 devices but no carrier bloat. Runs perfect on US ATT. It can also take CSC Firmware updates from MM1, SIN, STH and XSP. All of these are Singapore based firmware updates.
It's also easily rooted (trips Knox) but with no custom ROMs available currently. I'm getting approx. 10h sot with NFC, BT, WIFI running non-stop and no power saving mode.
So one fella says it has no carrier bloatware and the other was says it has.
I don't know who to believe ;/

You can call them and ask what Model IDs they have available. They had both a G928i and G928c when I ordered a week ago.
I am using G9287 seems not getting any high SOT for 6-7 like others usually around 5 or less not sure if dual SIM will use more energy but I am just using one card anyway

People need to be aware that the International market is not like the US market. Generally speaking we don't have custom versions of a phone, so all devices could be the same model, but the 'carrier' (network) may still lock it and install there own software.
So a 928i may be available as a generic unlocked phone with no carrier bloat, or it may be full of it. It all depends where it came from. In the UK models are usually locked and bloated if you bought direct from the network, but if you bought from a third party reseller (on any network) they are usually unlocked and bloat free.
Got my G928i, zero bloat, fully unlocked. pretty happy about it.
Went from a 4 inch(iphone 5) to a 5.7 screen, it feels enourmous, I like using my phone laying down at night at it feels awkward holding such a big phone now XD

EE Wifi Calling

Is anyone looking to work on this for the Nexus 6p?
I have one preordered from the play store and as such won't have the "feature" enabled by default (as you have to purchase the device directly from EE so they can load their own stuff on it)
However, seems the guys in this thread came pretty close, some got it working http://forum.xda-developers.com/galaxy-s6-edge/help/ee-wifi-calling-t3082364
At first it seemed like a few simple XML changes were all that was needed, i can't in fact make out from the 12 page thread if thats correct or not, some claim it worked with these changes, some said flashing EE's own firmwares etc was needed.
Please post any knowledge on this here, anyone who purchases from EE and is willing to share information/dump firmware would be greatly appreciated i'm sure :highfive:

I'll be interested in this as well, I've ordered mine from CPW on EE. I'm sure there'll be no problem enabling it we'll just need to extract the required elements from the EE ROM. I'm sure someone will produce a flashable zip.

I'm sure someone will. This is a nexus device, the owners tend to be more technically inclined so I don't think it'll be an issue.
The EE wifi calling is more than just a change of an xml file (which is Samsung specific) They use a VPN tunnel for the wifi calling which is not an application you can install and is embedded into the EE firmware for the S6/Edge.
Also don't forget that EE only allow wifi calling on phones brought through EE (in store and online) and I do not know if a pure stock android N6P would even be EE branded with wifi calling enabled etc.
I thought all nexus device came with stock android even carrier devices a

They only "allow" it because of the embedded firmware you mention, not so much a decision to disallow it.
My hope is that whatever code is embedded could potentially be extracted/applied to stock? I guess we need someone here with an EE nexus to help us out . My other half just received a google store notification that her 5x is being delivered today, so maybe someone with a 5x direct from EE will be around soon :fingers-crossed:

The chances are pretty much 99.9% that a Nexus brought through EE won't have any EE bloatware added whatsoever and will be pure 100% stock.
I'm hoping it can be extracted/reverse engineered also - but I wouldn't expect it for a little while at least.
The guy who has a 6p that posted a couple days ago showed a wifi calling option. He was on t mobile. I never got to where he replied if it worked.

I'm really hoping this is the case. I get F&F discount on EE so it makes sense to get my handset through them at serious discount. The only downside is that my previous devices have all had EE firmware, bloatware and SIM lock on them.
If the N6P comes unmolested then that would be perfect. The only thing I can see them adding is SIM lock (although I disagree with this on principle too - I should be able to put whatever SIM in my phone I want....).
I'm struggling to get any useful info on whether the Nexus will be hacked around by EE - I would sincerely hope they are prevented from doing so by Google as the entire premise of Nexus is that it's pure Android and all the benefits that brings...
Because it's a nexus and there is only 1 model number for the international variant there shouldn't be any ee bloat, just the same as the iPhone. And therefore any 6p should work with WiFi calling on ee just like the iPhone. Ee have already advertised the 6p as having WiFi calling so we should all be good to go. The ee representative I spoke to when sorting my new sim only contract assumed that this would be correct.

If that turns out to be the case I'll be very happy, I guess I'll just have to wait until Monday to find out.
I concur. Also waiting to see if they're going to get the 64 and 128 versions in. The lack of SD card is the only fly in the ointment for me so far (I have a 64gb card in my One M8 and wouldn't want any less now).
I bought iPhone 6s Plus directly from Apple and was surprised I could make wifi calling, just Enabled wifi calling under phone settings. I was informed by EE only phones bought directly from them would come with that option.
That'll be interesting then, it suggests there's something proprietary to enable it on EE devices?

For EE, in this case I believe they are making software changes so the 6P's from them will probably have a different build number. Though I need to find others who appear to have unlocked international versions come from EE (it does happen) who still have different build numbers to people who bought it from agnostic stores.
I don't know why some people are so confident EE will change nothing. They are making firmware changes on all other devices with WiFi calling, nexus willl be no different
Regardless of what people think the answer as some suggest is not to buy from EE direct, I didn't start the thread for that workaround, I don't want a device from a carrier I want it from Google. I don't want it sim locked or touched by anyone else, that's fair right?
My other half received her 5x two days ago so roll on 6p deliveries!
You should test to see if your other half's 5x works with WiFi calling on ee.

Samsung S8 - Unlocked Phone - No Wifi Calling? What Else Am I Missing

I bought an unlocked S8 at Best Buy because it was a good deal.
However, I'm noticing AT&T is restricting Wifi calling. There isn't even an option to turn in on.
Are they preventing this? If so, can I get it turned on by them ? I'm assuming there is a ROM I could flash to get it, but I would hate nothing during flashing bricking my phone.
Any other features I'm missing? Since I have really bad coverage at my desk at work, WIFI calling is important to me. I'm considering returning the phone and going to ATT brand, but there is a $35.00 restocking fee. I feel Best Buy should have told me the downsides of an unlocked.
I didn't get any restocking fee when I returned my ATT S8. Got a full refund, no questions asked. Besides if you're just swapping out to another carrier one, I'm sure they will waive it. I have MintSim (Tmo) and WiFi calling can be enabled and works fine for me on the unlocked firmware on my Vzw S8.
AFAIK, AT&T does not allow wifi calling for non-branded phones.
Can anyone explain to my why this would be? Is there any technical reason that they cannot do this on an non branded phone or are they being difficult?
I know it could be that they are strong armming me into another 2 year agreement, but if I can't use Wifi Calling, I cannot use their service due to poor reception at work. I think it would be in their best interest to let me use this feature.
Everyone I talked to on phone and in store basically act like it should be fine.

WiFi is not possible on AT&T network with the Unlocked version of S8 phones
This may help others who are considering the Unlocked S8.
Note: As of today, no options available from either AT&T or Samsung to enable WiFi calling.
After multiple trips to AT&T, BestBuy Samsung, chat sessions with Samsung support and now calling Samsung Premium Care, I finally confirmed that the Unlocked S8 model does not have any possible software upgrade to enable WiFi calling. Why did so many not know?
Samsung:
Please revise your website to clearly state the limitation, (WiFi is not possible on AT&T network ), with the Unlocked version of your S8 phones.
What's Next?
I was told that there is nothing that Samsung can do for me but Return the phone for Refund.
Now returning this phone requires me to again pay additional cost for replacing/activating another SIM for my old phone to use during the time I process an order for my next phone. Samsung cost me hours of my time and wasted my money.

dealing with the same thing and entirely frustrated. so much wasted time that a simple disclaimer would've saved me from.
wifi calling is a feature enabled by a carrier, not the phone brand. if you want wifi-calling, flash the relevant firmware for your carrier just like i did for VZW to get wifi-calling to work. and btw, this information was widely known by doing some research previous to purchase. i had no problem finding this out but ordered anyway with the intent to flash the firmware.

If in fact you DID buy an AT&T S8, you can unlock it and keep said features, but not in reverse of that. Which blows.

That really makes no sense.... (Not that you're lying) but there's specific firmwares for the unlocked S8's depending on carrier. the G950U1 has different CSC's depending on what carrier it's used for. Why do that if it doesn't enable that carriers features?!

flashing other carriers might work (like Tmobile), but not with ATT as they are using based on the IMEI registered with ATT brand.. so flashing any CSC won't enable it as long as you spoke to their customer care and provide your No and other ATT phone to activate Wifi calling on your number.. this is not 100% working method.. search through teh CSC selection forum there people posted a workaround.

Time I understand. You will never get that back. The SIM card issue I don't understand. Didn't you keep the old sim card from your old phone. Yes, AT&T will have to reactivate it, but they should do that for free. The only time I've had to pay is when I needed to get a new physical SIM card because the size was wrong for the phone I wanted to use. If you kept the old SIM card, you can simply reactivate it and stick it in your old phone again.

it's all tied to your IMEI, and that can't be changed. the VoLTE and Wifi Calling are non-existent unless you bought an ATT branded phone.
Guys ... I'm still looking for other options BUT this will work ....
If you have a business account you can just go in to the account and change your billing acct IMEI for your unlocked phone to an IMEI of an AT&T S8 (get one from a friend, go to the store and check out the displays, etc)
If you don't have a business acct call support , eventually you can get a person that knows what to do and they can plug in a working IMEI
This works ... works on my S7 Edge as well
Flashed unlocked phone with ATT FW. Then changed my account's imei with the imei from an ATT branded phone and that got me advanced calling options. Wifi calling will worked for about 10 seconds until ATT reads the phone's actual imei and then they turn off wifi calling. Volte will continue to work.
AT&T OTA Update Coming
All, I have just confirmed with AT&T they have made the request for an OTA update to enable WiFi Calling in the Settings Menu from Samsung. The time frame I was given as of yesterday 10/2/2017 was 14 days. So by 10/16/2017 S8 & S8+ phones should receive an OTA update that enables WiFi Calling feature.

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.

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.

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

Did I make a mistake getting the "UNLOCKED" version from samsung.com? I use AT&T and

Did I make a mistake getting the "UNLOCKED" version from samsung.com? I use AT&T and
I use ATT and verizon.. and i noticed when the phone restart it doesnt add the bootloader for either carriers which also noticed no wifi calling .. and voice over data with ATT is trash for some reason .. when i hung up the phone my data just goes completely away then comes back as "LTE+" ,,, this is sad.. my last year S9+ when i put ANY sim card in it, it restarts the phone and loads the correct "bootloader" for the correct carrier with all features such as wifi calling/voice over data. etc etc... thats my first ordering a true unlocked samsung phone from the mother company. am i doing something wrong where i missed something in the setting? i looked also for OEM option under developer options, its not there .
some advice would be greatly appreciated .. yes i dont mind the extra carrier stuff when i put sim for verizon or att .
i got the S10+ 1TB version.

The BYOD firmware isn't available for the S10 yet but when it is I'm pretty sure you will have to flash the carrier U firmware to take advantage of that when it's available. For now I think you have to flash each carrier separately to get their features because a simple sim swap dosen't do it. The U1 firmware witch the unlocked version from Samsung has shouldn't get the carrier bloat otherwise that would make it just like the carriers versions witch would defeat the purpose of purchasing the unlocked from Samsung. I have two unlocked Note8's from Samsung here and they don't have any carrier bloat like the Verizon U versions and what not.
I had the unlocked Samsung S8+ directly from Samsung and my only complaint was all the carriers would receive the updates before I did.

anyone got a direct link where i can be guided how to install a ATT firmware then? that'll be better for me i believe
I got an unlocked version of the s10 plus and thought I made the mistake also. I seem to be getting everything my tmobile s8 plus did like wifi calling and hotspot. I believe I can even surface the web while on the phone like I could do before switching. The unlocked version just doesnt have the boot splash screen that I hated. I think I will try and buy unlocked from now on

You should be able to return your phone for a carrier through Samsung or sell it. Someone would rather have an unlocked version compared to a carrier version. One just sold on Ebay today for 1,000. Hell I was thinking about selling mine and getting another one from Samsung

Tmobile carried simultaneous voice+data forever. It's standard for GSM networks with 3G or greater. Even the 1st android phone could do it. So you must've used Sprint before, where they gained that feature recently.
Unlocked models receive OS updates last, but seem to get consistent security patches.
