SM-G950U vs SM-G950U1 - Difference? - T-Mobile Samsung Galaxy S8 Questions & Answers

As far as I can tell, the U is carrier locked to T-Mobile, and U1 is unlocked, is that correct?
https://swappa.com/compare/samsung-galaxy-s8-g950u-unlocked/samsung-galaxy-s8-tmobile

You got it. Swappa is pretty reliable on their specs. For nerds, by nerds.

U is carrier locked, and U1 is USA unlocked

So any MOD, ROM meant for U will work on U1 too?

How does one know the original model since all these can be changed with firmwares?

So if it's now locked to Sprint (which is cdma) can I still use it on gsm networks if it's unlocked? S8 has multiple bands right?

Yes, all SM-G950U phones in the US should support the same networks including GSM. I had a Sprint S8 that I unlocked and it worked on Tmobile and ATT without issues.

I have a Sprint S8 that was unlocked after I bought it and now using it with my own carrier (in South America). Only problem I have with it is mobile hotspot. There's no option available for hotspot in the settings.

Well, yes BUT the U is carrier (and bootloader locked) so, there aren't any roms or mods to begin with.

[Q] Can the N910t be used with a different carrier right out the box?

Hi everyone,
Im thinking of getting the T-mobile Note 4 because its the most "usable" model since its bootloader is unlocked, it has different roms to choose from and can be used with LTE globally. I know there is an international model (N910f) but it seems it has trouble with LTE in the US.
So the question is, can I use the N910t (T-mobile) with another carrier right out of the box, if unlocked? Meaning the phone never touches a T-mobile sim card.
Thanks in advanced!
It will need to be unlocked, then it should work on most networks. The LTE will Not work on Verizon or sprint though.

Be careful with the LTE network. If you want to use it internationally you better check the frequency of the local LTE carrier. Most international carriers use a different frequency. Use this page to guide you en.m.wikipedia.org/wiki/List_of_LTE_networks

Yep so when I supported Verizon devices the one thing that always struck me odd was how many went overseas and out of the us. It was because they were sim unlocked from get go.

Verizon phones are always carrier unlocked by default. It has something to do with an agreement they sign with the fcc back in the day. All 4g lte phones have to be unlocked by default for Verizon.

Interesting. Thanks for this info. TIL.
On a slightly similar topic, I have a Verizon Note 8 (that is unlocked, already checked with my t-mobile sim), and I wanted to verify a couple of things. If I were to flash, via odin, the stock non-carrier firmware, will it basically be the same as what you would get from Samsung (i.e. an unlocked note 8)? The main reason I ask, is there are various flashing processes on xda, from unlocked firmware, carrier firmware (which I assume is refereed to as stock in certain xda threads), and carrier switching. Is the carrier switching processes only required when you want to specifically run the carrier firmware? (and thus changing the csc value). If you already have a carrier branded sim unlocked note 8, all one needs to do (to make sure it works as any other unlocked note 8) is to install the Samsung unlocked firmware?
In other words, if I flash the stock unlocked Samsung firmware on my sim unlocked Verizon note 8, will it work on t-mobile with all of the supported bands, etc.? (it is my understanding that carrier features on t-mobile work fine on unlocked samsung phones, such as wifi calling, volte, etc.) Or would I also need to load the userdata file to get those features?
I have searched and read so many threads, and sometimes I feel like I got it all figured out, and then I read threads that seem to confuse the whole situation.... (and most threads seem to be revolving around carrier branded vs an unlocked phone, or sim unlocking a carrier branded phone)

Unlocked Note 9 SM-N960U1 Doesn't work on any network

I purchased an unlocked Note 9 and all the networks tell me it won't work on any of theirs. AT&T, US Cellular, Verizon, Net10 all say no. I put my AT&T sim in and it works with low signal. Why would it not work? How do I figure out where this phone originated? I suspect Sprint because any phone from Sprint only works on Sprint.

Go to this site and run the IMEI. It will tell you if it's actually a U1 model or if it's a carrier model.
http://imeipro.info/samsung_imei_check.html
Whichever it is, you can just flash the ATT firmware, and it will work perfect on ATT. All the N960U and U1s are identical. Just different firmware.

So if you got it with flash for sprint then maybe you need flash what was originally on this model?
I have the very same model and I just put in my LTE Verizon SIM and it worked right away.
This model is a boot locked, carrier unlocked, world band snapdragon version, that was never originally touched by any carrier.
I.E. No carrier bloat ware. SM-N960U1

I flashed AT&T but cannot get wifi calling. I ordered an AT&T one through Samsung last night. I'll return this one when I get it. The back of this phone says it's an N960U.
I forgot how crappy carriers are. AT&T unlocked my iPhone but no longer recognizes it. So, I can't get wifi calling to work before switching the sim.
Thanks a bunch to everyone for their input and workarounds! Have been out of the loop for a while.

Oh, my bad, yeah the "U" models do say you might lose Wifi calling. Good it worked out for you!
I would be disappointed if I needed Wifi calling, I use the cell line 24/7 here in the US everywhere I go.
I feel like Wifi calling is just giving my carrier a break.

There's actually a way to get WiFi calling on it working again. Look through the carrier switching threads in the Note 8 forums.
It's why I hate ATT and love T-Mobile. Everything works out of the box on T-Mo.

Well to be fair there will be places where signal will be weak or non and then you will be the one loosing.
They don't look at break is just way for the customers to get better signal every where they go or inside whatever tipe of building...

I also purchased an unlocked Note 9 on ebay. In "about phone", the model number is listed as SM-N960U1. On the back of the phone, it's SM-N960U.
The sites that tell you the model with the IMEI number are right, it's a Sprint phone. Samsung customer support said the same thing. However, the Sprint phone and the US unlocked phone share the same FCC ID.
Does that mean, they are the same radio hardware? Is it just the firmware that makes the difference in band capability? If you flashed the US unlocked version of baseband, would it be identical to the US unlocked version? I just want to make double sure!

Wifi calling with an unbranded Note 8

I bought an unbranded Note 8 directly from Samsung. I find that this version does not have native Wifi calling. I am aware of some services that provide free Wifi calls as long as both are using the same service (Skype, whatsapp, and so on). My current provider is AT&T, FWIW.
Has anyone found any app or workaround that provides me with Wifi calling? Is there any way to get this for general phone work?
You will need to flash the ATT firmware with ODIN. Just be aware that it will also add ATT bloatware apps.

If you're on ATT, you'll need to use ODIN to flash the carrier firmware. This will bring back WiFi calling and VoLTE. But it will also bring with it all the carrier bloatware apps.

Do I have to get a VZW Note 9 (960U ?)to have Wifi and HD calling on Verizon?

I just cracked the front glass on my Note 8 and UbreakIt wants $250+ to replace the glass/screen so I am looking into a Note 9 as an option.
I am wondering Do I have to get a VZW Note 9 (SM-N960UZBAVZW for instance ) to have Wifi and HD calling on Verizon? Or can I buy an Exynos model and wifi and HD calling will still work on the VZW network?

no, but you do have to be running vzw firmware which is flashable in Odin.
you CANNOT use a Exynos anything on vzw tho. gsm only phones.
any of the N960U models will work as long as they have the vzw firmware on them
ps: it requires the vzw f/w because its a vzw service that needs to be provisioned

fell free its just that saying that a korean n9500 is a snapdragon device is wrong in many ways.
plus the correction of saying its a korean n950 snapdragon is also wrong. a typo is a mistake that dosen't really change anything in a statement. being wrong across the board needs to be adressed or at least corrected especialy when this information was supposed to serve as help and be informative to another user(which in this case had 2 problems in the statement). I'm not trying to nit pick at you, more at the relevance and correctness of your posts so that others get the correct information.
the only bootloader unlockable snapdragon devices are the Chinese and south American n9500, n9600, etc.. and so on
the korean n950n, n960n and so on are exynos.

on n960u and n960u1 devices, which are multi sim, have all US carriers csc files already. it will just switch.
on international devices such as the n960f for example, this behavior will not happen since the region of the device doesn't contain USA (XAA) csc.
but that's just talking about csc.
if we talk about modems and the technology used to connect to bands, Verizon uses CDMA. all n960u and n960u1 have the hardware to use both cdma and gsm. on the other hand, the n960f ( and F/DS or even n960n) unfortuanlty do not have the hardware required to connect through CDMA networks. so F devies wont even connect at all to provider.(neither F/DS or n960n)
this is pretty common knowledge and is not new. search and read.
one caveat would be the intl. Chinese or South American N9600 devices. they have the ability to connect to both CDMA and GSM networks plus having the ability to unlock the bootloader(custom recovery/rooting). the advanced carrier options will probably not work completely( csc). but that being said ,calls and data will work fine. uppon rooting, some of the xda community have made flashable zip files to try and restore these missing csc festures.( volte, wificalling ...etc)

incorrect. Exynos devices are GSM only and will run on virtually any stateside GSM provider. The main two are AT&T (as you mentioned) and T-Mob. Exynos versions of this phone will work on either of those and pretty much any other GSM service
