I saw a couple of tech points in the other threads. I myself have purchased the Att variant and planning to set it up with T Mobile but as I said, someone pointed out that they have different cellular banding or something to that effect. This person went on to say even if we were to get the ATT Gear S version on T Mobile that speeds would probably only be 2G.
From the articles that I've read on the Gear S specs I haven't come across anything saying that Samsung has designed specific versions for each U.S. carrier.
I do not have the answer at this time whether or not full cross compatibility is built into the device or not. Purely going by what has been announced, again I do not think it has been modified to keep us from doing carrier jumps.
I will update when Tmobile gets their networks up and running for the Gear S. If anyone can clear this up with for sure information, please do so. Feel free to speculate but if you're not certain please say so. Thanks.
If I can't get full functionality on the TMobile network with my ATT purchased and unlocked Gear S, I guess I'll have to return it and pony up the extra $50 that TMobile charges and fully join that club. Guys it may not be worth the hassle. I'll have an update soon on how all this works out, however I'd like to welcome feedback on the issue.

Im doing the same thing tomorrow.
You can go to Samsung.com to check out the official spec. There are 5 different carrier variants but only three listed so far: AT&T (SM-R750A), Verizon (SM-R750V) and Sprint (SM-R750P). The missing two are T-Mobile (SM-R750T) and US Cellular.
Each listed different supported network (CMDA vs GSM) and bands.
It has the Snapdragon 400 which supports a HUGE number of bands and supports a global mode for both CDMA and GSM.

Someone will figure out a way to get the device to work with them back and forth ... it may be through a rom or a command line. But if you aren't a tinkerer you'll probably want to go with the version of the watch for your preferred carrier.
Update: I did a search through the FCC and didn't see one with T-Mobile specific bands (1700/2100). Bad news though is that there definitely are two variants for CDMA AND GSM. Argh. I stand brutally corrected!
I was given Gear S (sm-r750) as a demo device. I worked with an att rep and got the sim card and device activated on service, but my device doesn't connect to cellular or data. I worked with tech support to work out the issue and tried refreshsing everything on att's side and even changed the apn settings. I have a Sprint Note III. I'm not sure if that has an effect on the gear s being activated. Has anyone else tried to do this/is it possible?
Shameless self-bump.

The carrier that your device is through does not have an effect on whether the gear will activate. I am using a T-Mobile Gear S with my Verizon Note Edge at the moment. I cannot speak for trying to activate the international model.
International version of Gear S will not have the frequency support of US carriers. Gear S is a dual-band device. International version supports 900/1800Mhz. US version supports 850/1900MHz. So, either version will get no signal what so ever on other area, e.g. US version won't work internationally while international version won't work in US.

Thank you. Not the answer I was looking for, but at least I know so I can cancel my account.
Hey all,
I recently moved to New Zealand from the United States. I have a Galaxy S6 edge with US Cellular (SM-G925R4) running 5.1.1. I was under the impression that I would be able to use my Galaxy S6 edge here because it is unlocked and because i'm under the impression that there's GSM Antennas in my device. Is this accurate? I took my phone to Vodaphone and Spark, and neither company was able to get it going, although all they did was place a SIM card in it. It just kept saying 'Searching for Service' and had no signal bars at all.
Does anyone know what I need to do to get my device working here?
Thanks in advance!
Alex
Bump! Guys I still really need help on this.
Bump again

Us cellular is a cd ma carrier. That is likely why it won't work in new Zealand.

Try Telecom. They are CDMA, Vodafone is GSM
First of all, thanks in advance for any help or tips you can provide! I did a search and found one thread from selveral months ago that asked a similar question, but no one had responded.
I have a Gear S that a family member purchased in South Korea directly from Samsung. It works great when it's connected to my phone, but I'd like to use it as a standalone device, preferably on Verizon. Verizon said their system doesn't recognize the IMEI so they can't add it to my account, but that I might be able use an already activated SIM card.
Unfortunately I don't have any devices that use a nano SIM like the Gear S, so doing this would be some hassle, and I want to have some idea that it would actually work. Looking around on line, it appears there may be a issue with the frequency band used by the watch and that used by American carriers, but I can't tell for sure if this is an issue for this device or whether it is surmountable.
Is there any way to get my watch to function as a standalone device on a US carrier? Can I use it on Verizon? If so, what steps are necessary?
Model number: SM-R750
Software version: R750XXU1BOG1
You have two problems here:
1. Gear S is dual-band only. Only US version will work with US carriers. Rest of the world use the entirely different bands.
2. Verizon is a CDMA carrier. It still uses CDMA for voice, text and 3G data. Only the LTE data uses SIM card. Verizon's version of Gear S doesn't use SIM card at all. So, even if you get a compatible US version of S, unless it has Verizon name on it, it won't work.
Hi,
has anyone experience with this Phone in the US ?
I having a -Mobile (USA) card in it and have mostly no Cell service, and if a Cell service than only 2 G
Thanks for your feedback

most of the things should work
I did look on this specs first, after I got it seems like there is something additional. There is one spot I get a super connection but 90% of the time weak or no Service at all. I have tried many phones before but none of them even had such bad reception. And there supposed to be even the Tmobile 5G 71 Band. It looks to me someone sold a restricted fu.... Asia version without mentioning it
go to settings and all the way down you should see your model number. Considering that USA specific is not out yet you most likely have asian one which is XQ-CT72. EU one is CT54.
But those should work on t-mobile network, most of the bands are there. And those are low bands, so longer range.
It runs at limited feature support. Sony disables VoWIfi for US models and many other features including Bluetooth features such as Bluetooth meta data.
Sony blames T-Mobile for limited feature set. you will need to root your phone to hack up the build to enable VoWifi and other features.
This feud between Sony and T-Mobile has been going on for the past 10 years and Sony still playing ignorant to US market.
if you don't care about such limited feature set, Xperia 1 IV should still work on TMO
I just got my phone yesterday and realized the same thing happened to me, I didn't have service where I used to but I managed to get it working by: going to settings, then network and internet, then Sims, scroll down to access point names. And two options should pop up, I changed mine to T-mobile US LTE.. And restart, which worked for me.

Are you saying the the imported version of the Xperia 1 iv does support VoWifi or neither one will on any USA carrier

that is correct, the issue is more related to Sony software rather than just the region. the only way to get VoWifi is to root your phone and disable sony software limitations

yeah this guide should work, its for the Xperia 1 III, I would think it would work for the IV, I just switched to goggleFI to get Wifi calling with out having to do anything.
Getting VoLTE and VoWiFi on unlisted carriers by flashing mbn file
I live in Canada and I have a BC72 (Asian version). I am struggling to get VoLTE and VoWiFi working. I know that mbn file is the key to getting IMS support and sony seems to block some carrier mbn files (only mbn in sales areas are available). So...
forum.xda-developers.com
I have been using the XQ-CT72 here in michigan on GoogleFi, which is basically t-mobile, in my town where I live, I get 5G without doing anything to the phone, but with that said, I work 20 miles out in rural area and apparently from my research tmobile use band 71 for 5G in rural areas, I can get LTE+ but no 5g at work, my Pixel 6 pro can get 5g but its like 1 to 2 bars that`s it, but with my sony I get full bars of better signal on LTE+ with my Sony, since the Sony is missing the n71 band for 5G, but I`m fine with what I get, since at work I` m on wifi anyways, I`m happy with my purchase, I originally had the US model on pre-order and the release date was pushed back to Sept. 22-23, so I cancelled my pre-order and bought a new one on ebay for 1069.00 compared to sony wanted 1599.00 for US mode
EDIT: I ended up send it back to seller, the 5g icon was not really 5g, if you're in the USA I would wait and buy the USA version, which I pre-ordered from Sony website, expected ship date is 22-23
moving to GoogleFI is the best option to use this phone in the USA. it will utilize Tmobile USA and have all feature enables.
Can anyone comment on Verizon compatibility with this device?
If really like to save some money and not buy the bootloader locked na version (if locked is still a thing)
Thanks

Only way to know for sure it to just buy it and try it for your usecases. Just buy it somewhere with a good return policy. I bought mine on Ebay with a 30-day return policy and so far it works fine on AT&T. Just make sure you do the trick where you disable dual-sim. (Google the details, it's somewhere here on XDA or on Reddit).
I bought my USA variant phone a week ago, and everything on T-Mobile works with the exception of Wi-Fi calling. The only alternative we have is to stop using T-Mobile and switch over to Google fi which does support Wi-Fi calling. Other than that my phone is flying super smooth and with fast performance like I've never believed compared to my old LG v30 Plus. I'm definitely impressed with this phone.

I'm using mine (XQ-CT62) in the Verizon network. Reception is not the best in the area where I'm but it works with no problem
Is that a coverage thing most likely, or the device itself? Rural area?

From a technical point of view, the phone should work on all carriers in the USA without issues, (with the exception of the Sony/T-Mobile Wi-Fi Calling issue that forces those who want Wi-Fi calling to switch to Google Fi, Mint Mobile, and other MVNOs).
Whatever service is in the area should work. Verizon will provision your phone to work with it's network. CDMA based carriers are supported per Sony's phone settings, so I would just go for it.
