T-Mobile vs. International Unlocked - Samsung Galaxy S7 Edge Questions and Answers

Sorry if this is a silly question but I have been interested in purchasing an unlocked S7 Edge from Amazon so that way I wouldn't have to deal with carrier bloat, but then I realized, if I'm using the phone on T-Mobile will I receive updates faster/slower than those who have purchased the T-Mobile version of the phone? Also will the phone still support Wi-Fi calling? As far as I know i'm pretty sure that's just baked into Android now but I could be wrong. Thanks in advance!

From what I researched, the international version won't support Wi-Fi calling unless you have the T-Mobile ROM loaded on it. Don't know about the updates though.

There was a rumor that Android was going to have VoLTE in it's software on VoLTE capable phones also- but that I think did not happen so probably no VoLTE on the International Model either- but not 100% sure.
The Exynos version will probably have better Battery Life- according to Ars Technica site.

Question regarding Galaxy S7 Edge (Exynos) Unlocked on T-Mobile in the US

Hello, XDA. I am currently considering purchasing a Galaxy S7 Edge (Exynos) unlocked for use on T-Mobile USA. I see that all the bands are supported here on the US, but I'm still worried about how well the phone works on T-Mobile. I recently heard that T-Mobile will block any devices without their own (T-Mo's) VoLTE certification from accessing LTE band 12 outright. Can anyone confirm if this is true? I would hate to purchase this phone and then find out I can't use it on band 12. I do not care for VoLTE/Wi-Fi calling, I am just worried about getting phone calls.
Also, overall, would anyone recommend this phone over the carrier version from T-Mobile USA? I have only gained interest in purchasing the Exynos version of the phone because I heard battery life and performance are much better. I really need a phone with good battery life and, from what I've heard, the Exynos version excels at this.
I would really appreciate if someone could clear this up for me. Thank you for your time.

AT&T: 930U or 930A

Hi - I am buying an S7 and am on AT&T.
I am having trouble understanding the differences between purchasing unlocked from Samsung / Best Buy (domestic version) or directly AT&T version.
I assume the AT&T version will have some bloatware but otherwise are there specific pros and cons I need to be aware of? I know they are both Snapdragon and other than that they seem the same so Im uncertain what to factor into this decision.
Thank you.

I bought an unlocked AT&T branded GS7 mainly because I wanted to use Wifi calling. Also, I don't believe HD Voice would work with an non AT&T branded phone.
No bloat
No wifi calling
No volte
No native video calling
No advanced messaging
I bought the unlocked version and so far no issues with LTE, LTE+.
G930A has FM radio chip enabled, while G930U not (yet?) . You have to install a third party app for it to work (bloated NextRadio) and being honest, the reception of the FM antenna (actually your headphones) is far from good, with a lot of noise in urban dense areas while cheaper phones on the same location are much better.

Which is the ideal version of the S8 to buy? Dual SIM international? Snap or Exynos?

Hi folks, I browsed this forum a few times and finally decided to make an account after all the wonderful information I've read here.
I realize there's probably no simple way to answer this question. But I'd like to buy the "best of the best" S8 I possibly can. I'm interested in the S8 specifically and not the S8 Plus. It's a phone I intend on keeping for a while, so long as nothing catastrophic happens. As such, I'm open to all possibilities.
I'm based in the USA but I would like to have the one with the most available bands to get the maximum availability on networks while traveling. I read on another thread that so far there are ways to unlock the bands in the firmware after flashing the Canadian firmware to the device. (I think this was referring to the Snapdragon North American version). But features such as Wifi Calling on T-Mobile won't work after that.
Because of carrier locks, it appears that certain models of phones only have certain bands enabled depending on which provider they were released for (AT&T, T-Mobile, Verizon, etc). This is a bit of a problem, if for example, I wanted to use an AT&T phone on T-Mobile, or wanted to pop in a local SIM while traveling.
I'm presently on Verizon, but I'm not under contract and so I'm willing to switch to perhaps T-Mobile, AT&T, or whatever other GSM carriers are available. As such, CDMA capabilities aren't really a major issue for me. It would be nice, but not a deal breaker. I also get conflicting info where some sellers say their unlocked phones won't work for CDMA carriers; while others claim that the unlocked phones have all the CDMA capabilities unlocked as well.
I'm wondering also, if the Snapdragon or Exynos is preferable? The general consensus among developers seems to be that Exynos is preferable to Snapdragon when it comes to future mods, rootability, etc. What is the downside to Exynos?
Lastly, what do you think of the DUAL SIM version? My main reason for holding off on my purchase is debating whether I should get the dual SIM version or not. It would be a nice feature to have, for a phone I intended on setting up and keeping for a while. The only hesitation as far as this goes, is warranty coverage issues.
Would the international version have all the bands enabled? I've also read the Chinese and South Korean versions have 6GB of RAM and 128GB of internal storage, which is pretty sweet.
Thanks!

Did you get your answers? I have same don't like doubts, specially related to processor and dual chip tech.

The only "downside" to the exynos version is the lack of CDMA support. It is superior in pretty much every other regard.
If you're considering a G950U.. I believe the AT&T model covers the most LTE bands. The Verizon version lists TDD LTE bands if those are useful to you. (But lacks other important bands)
To your question, the G950F/FD is likely your best bet.
Where do I found a list of models? I saw that in Brazil we have SM-G950, but what I see is here is only SM-G950F
Sent from my XT1575 using Tapatalk
I guess if you go with the exynos variant you will miss near fully playable gamecube/wii emulation. The exynos does other stuff better tho.
For the dual SIM variant, they have also just released a 6gb/128gb version, model number is SM-G9550. That's the best one you can get for the dual SIM variant: http://www.samsung.com/hk_en/business/business-products/mobile-device/smartphones/SM-G9550ZKGTGY.
Only downside is no Band 66 support though if you are planning to be on T-Mobile.

Hi, where can i buy the S8 Plus SM-G9550 (128GB, Snapdragon, 6GB Ram)?
thx in advance
Hi mate iv always preferred going for a G9xxF/FD version since They are Exynos in-case of Root or mods Exynos gets them first and if u get a FD added advantage of the dual sim. Good Luck
Hi codex1998, i don't need root and mods. My opinion is that the SM-G9550 is the better and most powerful phone.
Hi everyone, how about official firmware updates for different models ?
Is there any difference which models receives updates, which not ?
Some of my friends use different models and here is my statistic based on their phones:
s7 edge FD (dual sim): Android 7.0, last update August 2017,
note 8 (I believe its F model): 7.1 - August 2017,
s8 FD (dual sim) - 7.0 - Oct 2017,
2x s8+ FD (dual sim) - 7.0 Oct 2017.

BB Priv Better Version for Tmo US ATT or VZ

I have an opportunity to snag a Priv that is either from AT&T or VZ for the same price. I have read that the VZ model fully works on Tmo US, but I wanted to ask if anyone knows if there is a better version between the two for use on Tmobile? I realize that the AT&T has a ton of bloatware but do not know much about the VZ model. I am mostly asking from a functional use if there is ant differnce from using an ATT model and VZ on Tmo. Hope my question makes sense. Any feedback and or personal experience would be greatly appreciated, thank you in advance.
Edit - can anyone tell me if the Verizon model on tmo can use wifi calling? I can't seem to find a solid answer looking online.
Look at the frequences in this list here for compatibility issues.
http://forums.crackberry.com/blackb...ry-priv-models-supported-frequencies-1043968/
AT&T version supports more frequencies in LTE, but no CDMA (Verizon)
Second, AFAIK the PRIV from AT&T has a wireless charging coil which is AT&T exclusive.
I heard Verizon sucks at keeping their phones uptodate and is slowing down updates, i can't confirm or deny this, as i have never been an verizon customer.
Wifi calling? No idea.
My opinion: go with the AT&T Version.

Tmo versión has wireless charging, also there is no bloat. It's visual Voice Mail, my tmo, and I don't remember ever having to disable anything else. Been using it since about launch.

Questions Re: International (or Latin) unlocked S10+ or Note10+ / T-Mobile

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.

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.

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.

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.

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.

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.

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.

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.
