I am leaving post paid service and going pre paid.
I since majority if prepaid US carriers are Sprint, T-Mobile and some AT&T. I want a GS 7 that will support all three carriers with as much bands possible.
Any suggestions or does the Sprint version support (once unlocked) support AT&T and T-Mobile.
Technically, any GSM unlocked phone would work on any GSM network, but that wasn't your question.
I ordered the sprint version to use with cricket (at&t network). What I read, the sprint version will support AT&T better than tmobile. In the end, once rooted, you could add in the band's not supported by default.
Music to my ears!
Will have to get the Sprint version and hope for the best.
S7E's sprint version can't turn off shutter camera. But im still happy with the 50%off promo
Has it been confirmed that the s7 uses sprints LTE advanced signal. I can't find a place where it says for sure like the g5's page .

I'd like to know this as well. I seem to get better 4G coverage in my area with the advanced signal enabled compared to my friends who don't support it.
Yes, my new s7 uses lte adavanced
Splash screen says so

Sweet. I have the nexus 6 now and considering getting one for the SD card access alone. Is there a noticeable difference in data speeds with the LTE advanced, does it offer data and voice at the same time?

It just seems that way, or it's because it has a better antenna in general. LTE Plus doesn't get you a stronger signal. The beamforming that helps at the cell edge is a tower-side enhancement. As long as your phone supports band 41, you're able to take advantage of LTE Plus - just not the Carrier Aggregation component.
I am very eager to see what happens in this regard as well. Sprint is notorious about locking down their phones to include very few LTE modes so that the phone is truly only for Sprint. Samsung's CDMA version of the Galaxy phones have been crippled in this way all the way up to the S6.
You can see various phones like the S4, S6, LG G4 and the S7. The S7 CMDA variant does not appear on this comparison chart yet but I'm hoping that it won't need to.
http://www.phonescoop.com/phones/compare.php?p=4066,4769,4773,5081,4928
The last phone in that comparison is the iPhone 6s Plus, which is the same no matter which carrier you use worldwide. I really, really hope Samsung does the same thing.
The only other phones with lots of LTE bands like the iPhone on Sprint is the Nexus 5s/6p and Moto X Pure.
PLEASE let LG and Samsung include all the default LTE modes by default on the CDMA versions of their phones!
Edit: nope, Sprint made Samsung get rid of the most important worldwide LTE band, 7, along with 13 and 20. LAME.

I'm thinking of buying the SM-G730P (Sprint) version of the Galaxy S7 even though I was all the years on Verizon and they are for sure the better service and have more coverage, at least here where I live, but the reason I wanna buy Sprint is just because Verizon just makes Samsung phones much more secure, and locks the boot loader, now the question is, First of all does Sprint still lock their LTE phones? And second of all, will an unlocked Sprint phone work on the Verizon network, and will it work overall perfectly when I'm aboard, on the International GSM network? And last of all is there a different in the build of this 2 phones, Verizon S7 and the Sprint S7, besides the bands

Today's news concludes that all US (Qualcomm) variants of the S7 indeed have a locked bootloader except for a select few apparently. Verizon and AT&T lock the bootloader tighter than others, such as Sprint. Sprint and T-Mobile didn't lock the bootloader themselves but rather Samsung. Samsung locked the bootloader to better add security to their consumers and there's been hints they may release an unlock kit/tool for developers but this hasn't been confirmed.
I got Sprint to unlock my G930P and works perfectly with AT&T. The S7, at a hardware level, is the same phone for all US variants where the only thing that changes is the software. Meaning a Sprint phone on the Verizon network would essentially have the same network performance as if you were to use an actual Verizon variant. Once the device is unlocked, at least for me, it knew my sim was on the AT&T network and switched the bands to AT&T on reboot.
Internationally, I'm not sure. There is an option to enable Global bands in one of the hidden menus in self-service but I'd assume it'll cover enough bands to provide you with what you need minimally. (I've never gone international before so can't say from experience)

GSM will work as expected.
LTE, however, will be crippled depending on the country you go to.
The updated spec list:
http://www.phonescoop.com/phones/phone.php?p=5081
According to that list, Sprint purposely took out three very important LTE bands: 7/13/20. Why does that matter? Because much of the world uses these three bands, especially band 7 and especially Europe! Sprint purposely crippled the LTE radio modes for this phone and I cannot understand why.
So yes, you'll probably get normal GSM and some LTE if they offer one of the other bands but Sprint purposely disabling or deleting the commonly used international LTE modes abroad is just anti-competitive and backwards.
Will rooting or unlocking this phone allow the use of the bands that were locked by Sprint?

The splash screen says LTE Plus, not LTE Advanced. LTE Plus is simply the new branding for Sprint SPARK. Was that the OPs question?
LTE Plus is not Sprint Spark , its more in depth. Carrier aggregation by antenna beam forming.
For those interested, Sprint is releasing an unlocked S7 that works on all the carriers and has a full range of US LTE bands:
http://www.phonescoop.com/articles/article.php?a=17870
Im hoping someone can please help me get up to speed here.
A while back I was looking at whether to get the AT&T version or the unlocked Exynos version sold at Best Buy.
From what I recall, many favored the Exynos version as having better real life performance and meaningfully better battery life. Also no bloatware.
The downside was that here in the US it would not work for Samsung Pay. From what I remember it worked just as well on AT&T's LTE network.
I have tried searching the forums to figure out if all of this still holds? Has Samsung Pay been made available - either through Samsung or through some kind of rooting, etc? Has the network performance been confirmed as identical between the two?
I am trying to decide which to purchase so any and all feedback would be helpful.
Thanks.
SPAY will not work and data transfers will be faster will the ATT variant.
Despite this, you should get the exynos for its fast mutli core capabilites, assuming you have no hope for a bl unlock and you care nothing about roms.
No way in hell does the Exynos model work as well on AT&T as the AT&T specific model. Not even the 930U.
With the 930A, you're gaining...
3xCA (bonds 3 LTE Channels), 4x4 MIMO (not active yet, but will probably require 930A), 256QAM (33% faster LTE speeds), WiFi Calling/Texting, RCS Messaging, and VoLTE. If LTE is your concern then the 930A is the only way to go.

So just to verify - does this mean that the 930U will have WORSE data and calling performance on AT&T 4G LTE network?

Data performance maybe, but not calling performance unless you have wifi calling as a necessity. Most people have lived without it for years, so I don't know how big of a deal it is for most people.
Thanks. I dont use Wifi calling although data performance is kind of a big deal!
Other than slower data on the 930U are there any other drawbacks?
Are there any BENEFITS for 930U? Its just unlocked right?
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?

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.

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!

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?
Does anybody use the exynos varient on AT&T or T-Mobile? I'm wondering if you get good service. I'm currently using an exynos S8+ on AT&T without any problems.
i had s9 duos exynos on att. excellent reception. im located in Boston.
Download speedtest to check your data/wifi speed
Thank you for the information. I looked up the S9 exinos on frequencycheck.com. It supports 3 out of the 4 4g bands on AT&T. According to the website the s10 exynos only supports 2 out of 4. So that doesn't help too much but I never thought about checking the s9 since I know it works well.
Works great for me. I got an Exynos from Australia when my phone died. Checked the bands for SM-G975F, and it has all the T-Mobile LTE bands EXCEPT band 71. So you will be good unless you go into rural USA.
Only thing I don't get is Carrier Aggregation. I have wifi calling and VOLTE..
Thank you for the info. After looking up that model it should work fine on both networks. That website I was using has wrong info on some of the models. I think I will buy the SM-G975F.

I also have the G975 F(BTU - United Kingdom) I live in Milwaukee on ATT Network. I get great LTE Speeds - the only thing I don't get is Wifi Calling and ATT Video Calling - ATT only supports their phones for those features - at least until there is a custom CSC that we can flash (like someone did for the Note 9, S8Plus, etc)
Do you have VoLTE at least on AT&T with the exynos?

Thank you for the info. I want to keep AT&T but I would switch to T-Mobile to get the exynos variant if needed. But I'm glad I can keep my service. I had the original IPhone and I'm grandfathered in to the original unlimited data plan. I didn't even know AT&T offered wifi calling. Before my exynos s8+ I had a note 4 and for about a year my moms extra free IPhone 6. It wasn't an option back then. I don't really care about WiFi calling though. I get good service where it matters most. I can't wait for S10+ Roms!

First you download a file or run speed test using speed test app, then at the same time dial *#0011# and select SIM slot it'll say CA added or CA active. This means you're getting some form of aggregation

I am on Exynos, wouldn't have this problem with the SD version (I'd hope). I have factory reset a few times, but never see the CA as activated. I'll check from time to time, but also away from my house it doesn't show that CA is activated. Might be the XSF (australian) version that doesn't aggregate the t-mobile bands.

That could be it. I'm using TPA CSC and some other people on that CSC confirmed carrier aggregation working on T-mobile.
Snapdragon (Chinese or Hong Kong variant) does not support carrier aggregation in T-mobile from what a user posted.

Do you need to flash a CSC and/or modem from a US carrier onto an exynos international phone to get VoWIFI, CA, VoLTE, etc? Or does it "just work?" If you need a special CSC do you just pull HOME_CSC out of a US carrier's firmware and flash it with odin or something?

Hi
You should not flash any firmware from a Snapdragon into a Exynos..... You may not be able to get some of the service provider options using the Exynos firmware, i guess is a try and see situation, but one thing is for sure do not flash a Snapdragon firmware into an Exynos.
Everything else should work , modem is ready for all frequencies but CDMA
in case anyone comes looking, i've tried it on an exynos G973F with XSG csc (one of the OXM multi ones) just because that's what was on the phone.
VoLTE seems to be working on T-Mobile in the US without any messing around, based on the "HD" icon appearing during voice calls. Voice over WiFi seems to also work.
The phone is dual SIM with a TMO sim and an ATT sim. It doesn't get VoLTE on ATT, but I believe that's probably because AT&T only allows it on approved devices.
So I am looking to buy an international (or Latin) version of either the S10+ or the Note 10+.
I am on T-Mobile in the U.S.
1. How "bad" will it be if the phone has 3 out of T-Mobile's main bands? It only lacks 71, so what's the impact will be if I don't have band 71 on this phone with T-Mobile?
2. I read in the forum about flashing T-Mobile firmware on unlocked phones. How necessary is it? I prefer not to mess with flashing anything; done it in the past, I am not 'afraid' of it, but I just don't feel like going that route. Will I be missing anything from the T-Mobile network and services if I keep the phone in its stock ROM?
For example: Wifi Calling (important to me), VoLTE, etc. Will I have access to these features if I don't flash the carrier's firmware?
Thank you.
Band 71 is used only in rural areas where cell towers are very far apart . My phones have never used band 71. If you don't know what bands your phone typically is using you can download a free signal app from the Play Store that will show what band your phone is connected to. Unless you live in a very rural area or frequently find yourself in rural areas it's unlikely you need band 71.
Flashing T-Mobile firmware shouldn't be necessary. I don't have the international S10+ but rather the US unlocked model and I get both WiFi Calling and Volte fine without T-Mobile firmware.
I've used many different models of international unlocked phones from Xiaomi and Huawei on T-Mobile and always got both WiFi Calling and Volte to work with only one exception--the Mate 20 Pro. I had to get rid of that phone even though I really liked it because calls kept going to voicemail without the phone ever ringing first.
It turns out that on T-Mobile if your phone supports band 12 it also needs to support Volte or calls go straight to voicemail without ringing if the caller is using Volte . I never had that problem previously because in 5 years of using international unlocked phones the M20P was the first where Volte didn't work on T-Mobile.
There were lots of posts from T-Mobile customers in the XDA M20P threads about calls going straight to voicemail. I haven't read a single post about that issue with the S10+ so it's pretty safe to assume that the international S10+ works fine with Volte on T-Mobile.
Until the S8 Samsung didn't even sell a US unlocked model--everyone in the US with unlocked Samsung phones were using the international models with the Exynos chip and those phones always worked perfectly with T-Mobile which is very BYOP friendly (unlike AT&T).
The only thing you would be missing on the vanilla Samsung firmware is Visual Voicemail but last I checked you could just download the official T-Mobile Visual Voicemail app from the Play Store.
You would also receive your OTA updates from Samsung rather than T-Mobile but that's actually a plus because the unlocked Exynos models receive updates much more quickly than all of the US models including the unlocked Snapdragon models.
Sorry for the very long answer but I wanted to be thorough.
You should be fine with an international unlocked S10+ on T-Mobile. This is a much better phone than unlocked models from Google Pixel and One Plus so I would recommend going for it.
No manual flashing on your part will be necessary.
@jhs39 - Thank you for your extensive response. It is greatly appreciated!
OK, so I mostly use Band 4 with my current phone, which is one of TMB's main bands, so it seems like that indeed the lack of 71 won't be an issue.
However, how do I know if the Int. version will support VoLTE on the TMB network? I can't see anywhere any information about this phone even supports VoLTE (other than the carrier's model of course).
What about Video Calling?
Thanks again.

If the international model didn't support Volte on T-Mobile there would be posts on XDA complaining about calls going straight to voicemail without the phone ringing. There were multiple threads about that issue in the M20P section but I haven't seen a single complaint about that happening with the S10+.
This phone has been out since early Spring so if there was a problem using the international model with T-Mobile somebody would have reported it by now.
I don’t know anything about video calling though because I use T-Mobile's network via an MVNO and my carrier doesn't offer video calling.

That's odd. I'm using a mate 20X and the although it lacks bands 66 and 71 I don't get calls going to voicemail. In fact when viewing my historical phone signal via gsam app, it shows that I always receive a better signal than even the S10+ that I'm currently using. Both devices on T-Mobile USA.

So I am looking to buy an international (or Latin) version of either the S10+ or the Note 10+.
I am on T-Mobile in the U.S.
1. How "bad" will it be if the phone has 3 out of T-Mobile's main bands? It only lacks 71, so what's the impact will be if I don't have band 71 on this phone with T-Mobile?
2. I read in the forum about flashing T-Mobile firmware on unlocked phones. How necessary is it? I prefer not to mess with flashing anything; done it in the past, I am not 'afraid' of it, but I just don't feel like going that route.

I have the Hong Kong variant SM-G975 with T-Mobile. No issues with bands, VoLTE. Wifi Calling or 4G, no impact. You won't need to flash the device.

Thanks @varcor . What about Video calling?
BTW - is it 975F or something else?
I use Skype for Video Calling, it works fine. Mine is an SM-G9750, the best price I've seen is on Ebay. The only issue is when you first get the device you'll need to change the language since it's setup in Mandarin. A bit challenging but not a big deal. The Ebay vendor is in Houston which is where the device ships from, only takes a few days.

I must the F model. I travel to Israel with a local SIM and they use the F model, and it's the only possibility I have to use their WiFi calling while there. I am not 100% sure it'll work because of firmware but better chances with F model.
Thanks.

Not having bands 66 & 71 don't cause the problem with T-Mobile calls going straight to voicemail--if band 12 is supported on a phone T-Mobile assumes the phone also supports Volte and if it doesn't then you get calls going straight to voicemail.
I'm not familiar with the Mate 20X but before the M20P I had a P20 Pro, Mate 10 Pro and P10 Pro and none of those phones had an issue because T-Mobile Volte worked with all of them.
It's also possible the problem with the P20 Pro was fixed after I got rid of the phone since it was a firmware issue that was fixable in a software update . I kept mine for 6 months before throwing in the towel. The only workaround was to turn off 4G in the network settings. With 4G off you would receive all calls since Volte is a 4G function.
I personally love Huawei phones. Hopefully after Trump is gone all of the nonsense with Huawei being barred from using Google apps and bullied out of the US market will go away but they might decide selling their products here isn't worth the aggravation.
I've also used a bunch of unlocked Xiaomi phones on T-Mobile with no issues. A nice feature in MIUI is that if Volte doesn't work out of the box there's a dial code you can enter to manually enable it.
Band 66 is an offload for band 4 when band 4 traffic is high but if a phone doesn't have band 66 it just stays on 4 so not having 66 on an unlocked phone has never caused any problems for me.
Band 71 is only live in parts of the country and is relatively new. It can transmit a signal over unusually long distances and is used to provide cell coverage in rural areas where it would cost too much to build a full network of cell towers.

P20 pro was certified and worked fully on T-Mobile , most devices after that were not.
I don't think my mate 20x connected to band 12, but if it did, then yes it'll probably go straight to voicemail.

The SM-G975F is the Exynos SoC variant for Europe. The SM-G9750 has the Snapdragon SoC and dual SIM's as well. Wifi Calling will work on both devices in any region, including Israel as long as the service provider offers it. The only thing I would recommend is you do some research on Exynos vs Snapdragon SoC's in the S10. Good luck!

I am aware of the differences between the two chips.
In regards to WiFi Calling - I am a bit skeptical. This provider does have WiFi calling services, however they have a list of devices that are supported. Clearly they list devices and firmwares that they sell, not BYOD phones, and they sell the F version. I currently use ZTE Axon 7, I have WiFi calling on T-Mobile but it does not work on the Israeli network and when I try to 'register' it for this service through their app, it clearly says that the device is not supported.
That being said - I can't tell you if my phone doesn't work on their WF calling because it's not even sold in Israel. It could very well be that any version of Galaxy S10+ will be supported regardless of firmware. simply because it is sold there. Clearly there is no way to know this beforehand. I asked them, they of course can only guarantee phones that are sold by them and are on the list.
BTW - the Israeli version of the 975F is single SIM, they don't have the D/S, although I can't imagine this should have any impact of phone supporting or not supporting WF calling.
What's the difference between the F and the O, other than the region they are sold in?
Thanks.

Devices don't need to be certified by T-Mobile to work with Volte. All of my recent Xiaomi phones worked with Volte--none of the models were officially sold in the US or certified by T-Mobile. The P20 Pro was not sold in the US so there was zero reason for it to be certified by T-Mobile. The last Huawei phone officially sold here was the Mate 10 Pro. AT&T and Verizon require that devices be certified by them to work with Volte on their networks but T-Mobile does not. T-Mobile is very BYOP friendly.

Thanks for the clarification. So why is it then that same device , but using different sim card would show the Volte toggle or hide it from the user menu? Example, mate 20 does have Volte capabilities yet its missing the Volte toggle switch. I know on the Xioami devices one can enter a #*code to force it show that option. I think what makes it even more convulsing is that Huawei global versions have various region firmware via their Cust codes. Each one I noticed behaves slighly different using same T-Mobile SIM card. Cheers
You mentioned all calls went to VM on up 20pro, why do you think that was the case, you mentioned earlier that you thought possibly it may have been firmware related amongst other things.

You're correct regarding Single SIM for the SM-G975F, the Dual SIM option is available in the SM-G975F/DS. I personally wouldn't consider obtaining a device in Israel if the majority of the time I'm the US. The major differences are SoC's, a minor difference in CPU Clock Speed and Cores. The SM-G975F has no FM Radio and offers fewer Primary Network capabilities. You can view a back-to-back comparison here.
https://www.phonemore.com/compare/p...gb-vs-galaxy-s10-plus-sm-g9750-128gb/10134260
This is quite different than your original question but with that being stated I would be confident enough in the SM-G9750's compatibility with the Israeli network for Wifi Calling. The worst case is not having Wifi Calling in Israel, which isn't an absolute necessity however you'll have the Snapdragon SoC which is a far better chipset with fewer bugs. For me it's the obvious choice if I were faced with your considerations.
You're most welcome

SoC, meaning the chip?
You see, your definition of "worst case not having Wifi calling" is important to me , simply because where I usually stay in Israel there is almost no reception at all (inside the house I am staying in), that's the main reason I want a device that will be able to use their Wifi calling.
Also, I looked at the eBay seller that you mention and I don't even think he carries the O model any more, all I see is the F model, unless of course I am missing something.
Thanks.

SoC is System on Chip, same as Chipset. If Wifi calling is a top priority buy the Exynos device to be certain but be advised there are numerous concerns over the chipset on XDA and other sites, plus Network Aggrigaton for Exynos in the US has issues with some T-Mobile clients. You may lose Wifi Calling or VoLTE in the US.
https://forum.xda-developers.com/s10-plus/help/exynos-att-t-mobile-t3920491
They still offer the SM-G9750, the link I shared is correct, not sure you missed something. The also sell the SM-G975F and SM-G975F/DS.
