IMHO the SM-G9750 (Hong Kong) is the best variant. Why? A number of reasons. There's very little Bloatware, works on all CDMA and GSM Networks, has Dual SIM's, Bootloader Unlocked and most importantly a Snapdragon SoC.
Mine is working great on US T- mobile out of the box. I have VoLTE, wifi calling and data speeds are great. Nice to actually have the best phone on the planet for once. Looking forward to root and adblocking!
I received the S10+ 128gb SM9750 from hong kong since last thursday. I couldnt be happier.
I plan to upgrade to 1TB sometime in April when the prices go down.
Best SoC, faster updates and a great network coverage.
If you have any questions, ask away.
Work Hong Kong version on Germany?

T-Mobile's CSC Code is TMB, the Hong Kong (SM-G9750) Active and Available CSC Code is TGY. This is the first time I've seen VoLTE and Wifi Calling working on a US Carrier's Network without changing the Hong Kong TGY CSC Code. How did you accomplish this?

I just put in the SIM card from my T-Mobile branded Galaxy S7. Apparently US carrier firmware is embedded and installed automatically depending on the SIM card. Pretty neat. My Samsung Pay is still the HK version but works fine. I'm missing tmo video calling, real time texting and advanced messaging though. Also phone does not support band 71.
where did you buy from?I also would like to buy HK variant S10 plus G9750 with SD855 and dual sim.But I heard it is missing band 71. For me VOLTE and WIFI calling is very important.Please advise.Thanks

VoLTE and wifi calling on TMo work great, but I've found the phone is not configured for carrier aggregation, which negatively affects download speeds. Oddly enough, upload speeds are generally great. I got the the phone on eBay from seller "never-msrp"

As an example, from home my S7 (with CA) generally downloads @ ~75 Mbps, and the S10+ is around 35. Samsung pay works fine but is Hong Kong version (Chinese ads etc.) Band 71 (600 MHz) is generally used in rural areas but is likely to become more important in cities in the next few years.

35Mbps is still quite fast. I wonder if that is with 2x CA. I have Exynos with limited CA and it ranges between 15 to 30 Mbps om Tmobile

I checked from the service menu (*#0011#) while doing a speed test and it's definitely not doing CA. I've watched it happen from there on my S7.
What's annoying is that it initially spikes to ~55 and then backs down steadily, like it's being throttled, or waiting for another tower to pick up the slack or something. Upload is the opposite, it starts slow and steadily climbs, almost always to a higher number than the download.
I'm in Manhattan and mostly have excellent coverage except for the 1928 building I work in that's built like a brick ****house. Wifi and HD calling are a must there. The signal repeaters are always on the fritz in my part of the building.

No call recording option. Also, the camera shutter sound can't be turned off because of HK upskirt laws. But if you put the phone on silent you won't hear it. Also in order to get the VoLTE and wifi calling status bar icons you need to pull down the status bar, hit the three dots and select button order. These features are apparently installed after you put the sim in. I didn't notice the wifi calling one before, but it's there. Enjoy your phones, they are truly amazing

Hi guys!
Was planning to buy Xperia X Compact, but need to find out if it supports T-Mobile features, such as Band 12, VoLTE and maybe WiFi Calling(not the priority for me). Any person tried this phone on T-Mobile?
I just got this phone yesterday and it's running fine on T-Mobile though I'm in a band 4 area right now. FrequencyCheck (https://www.frequencycheck.com/models/GNNDM/sony-xperia-x-compact-f5321-td-lte-sony-kugo-ss) says it supports band 12, but I have yet to experience it myself.

Technically speaking the phone does support it, but would be interesting to see if phone does support it on T-Mobile network.
Time will tell on this one. Tmobile has been picking up a lot of 700 mhz spectrum lately but it's not all deployed yet. I think it's mainly due to awaiting FCC approval.
Are you guys using the US version? I ordered the UK version and I'm sending the US back to Amazon because I want the fingerprint scanner. Don't feel like flashing the phone. I'm assuming they have the same bands for Tmobile. Well hopefully they are the same.

Hopefully nothing goes bad on you within the first year. You lose your warranty with the UK version. The US version is so incredibly easy to flash firmware. You just launch a program and click a few options.
Band 12 works fine for me. I believe the phone supports all T-Mobile LTE bands, I get pretty good speed tests too.
I don't know if or how wifi calling would work. I've never seen a way to get it on non T-Mobile branded devices, I would certainly be interested in enabling it though.

I think Nougat has wifi calling baked into Android itself if I remember correctly. So hopefully the update comes soon.
I'm debating on buying the X Compact or the X Performance. The Performance has a 5 inch screen, not much bigger than the Compact. Anyone with any thoughts on the X Performance ?

Can you test whether it actually supports VoLTE?
When connected to band 12, try making a call: if it drops to H+ then it supports band 12 but no VoLTE.
If it stays on LTE during the call, it actually works with VoLTE

It does not support VoLTE.
The phone does but TMOb has not certified it to work on their network.
I'm really tempted to return my SD S8 and get an Exynos.
I had an Exynos S7 before and signal coverage was absolute **** in my area. Even though all 3 T-Mobile bands were supported, it was just ****. The speeds were **** and the experience was ****.
It's a lot better on my T-Mobile S8 but that flashing itch is still there, I don't want this locked bootloader.
Has the Exynos S8 improved any?

Bands vary by region. The UK and I'm guessing EU versions don't support Band 12 which is T-Mobile's low frequency bands. Low frequency helps with distance and obstructions. That would explain why you got ***** performance. You need an Exynos device with band 12 if one exists.
In terms of carrier vs. Exynos my UK S8 gets better LTE speeds than the AT&T branded S8 I was using on their network for two weeks before its UK replacement arrived. The only AT&T band the EU phones don't have is band 30 which is high frequency and not widely deployed so not as necessary as band 12 on T-Mobile.

You can't install a snapdragon based Rom on an exynos based phone. You can flash a CSC that enables Wi-Fi calling in the exynos phone with root. Search the forums, there's been a couple posts about it for the S8
I am considering upgrading to the S8. I like that the G950F has an unlocked bootloader on a phone that has (almost) everything I want.
But it seems like it's a bit of a hassle to get it to work fully on the T-Mobile network. It looks like I can flash the CSC to enable WiFi Calling and VoLTE on it, but is there any hope for 256QAM and 4x4 MIMO? There's hardly any information about this other than one or two threads. So I'd like to know:
If I go with the G950F over the T-Mobile or Unlocked US variants, what am I missing out on out of the box?
What will flashing the T-Mobile CSC not fix? (I currently think it does fix WiFi Calling and VoLTE.)
Can I flash the T-Mobile US modem on the G950F to fix this, or will that just brick my device? (Snapdragon image on Exynos terrifies me.)
Am I missing some other way (like a secret service mode or something) that would allow me to force 256QAM and/or 4x4 MIMO on the G950F?
I really hate that I can't just have a US model with an unlocked bootloader...
I think Galaxy S8 International variant maybe missing some bands and I would suggest you either get T-Mobile as you mentioned or US unlocked. With US unlocked which I already ordered from Samsung, should support all T-Mobile features: VoLTE, Band 12 and WiFi Calling. At the moment Samsung offers $200 off if you trade in any Android or iOS device. Just check their page for Trade-in details.

Hmm, I don't remember which bands exactly and how many, but F model had some bands missing for T-Mobile.
Just one night frequency
The exynos variant lacks 4x4 mimo and 256qam from what I've read. It achieves 1gb down via 5xCA. But also only allows it to max upload at 150mb/s
So it would only be able to utilize the 3xCA from tmobile. And not get max possible downloads. But the F does support all 3 of t-mobile's used bands

Got it. That's what I was looking for, thanks. My understanding is that it's a hardware issue that can't easily be fixed via service mode or flashing something, but it doesn't look like I'd miss out on much overall.
I am in a 4x4 MIMO service area though so maybe I'll just hold out for now and see what happens over the next few weeks/months.
Can someone point me to the thread for how to make a sm-g950f have volte and wifi calling on T-Mobile?
My searches turned up nothing concrete if this is possible but I found a Note 8 thread that sounded promising.
Does anyone know if I were to flash the latest Germany T-Mobile firmware (DTM) from Sammobile, would that enable VoLTE, WiFi Calling here in the US?
Currently my G950F S8 has the Australian (XSA) firmware installed and it doesn't have VoLTE or WiFi Calling. The WiFi Calling setting in Quicktiles is greyed out.
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)

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.

For which model the Chinese Snapdragon?
CA is working for me on Exynos. It is not the same as US Snapdragon CA but still better than no CA at all

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.

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.
