I've been reading about firmware and how users flashed the T-Mobile Firmware on their S8's to gain some services. Am I missing anything with my S9 and keeping it on the unlocked firmware? I've searched these forums and the web but there are no sound conclusions if I am hurting my service by not flashing the firmware.
Thanks for the help

No. ALL TMobile features work with the US unlocked version. I'm using one myself on tmobile.
The only "feature" you'll be missing is the 600mhz/B71 band on T-Mobile, which is new an somewhat "upcoming" anyways. I think the S9 Tmo is one of the first phones (if not the only phone) to support this band.

The first phone carried by a US carrier to support the 600MHz was actually the LG V30. Since then the Moto Z2 Force, S9, S9+, Note 8, and S8 active all support 600MHz. Last week LG launched the first budget phone to support 600MHz, and that's the LG K30 at $225.
Edit: All, if not almost all of the phones I listed have native support for 600MHz (assuming Snapdragon versions), so all carriers phones if unlocked will be able to take advantage of the 600MHz on T-mobiles network.
Multi line (digits) doesn't appear to work in the unlocked version. The app still functions though, however the experience is so much better when it's baked into the firmware.
I'm on a sm-g960w on Rogers and they have a 2600mhz band that's nice when nobody's on it lol.
I recently flashed over to ARC6 (tmb I think) and then sideloaded an update up to ARDA (may update). My device reads sm-g960u now and I'm wondering if I'll still be able to get on that band.
Thanks in advance if anyone knows, the way I usually measure isn't working and I don't have root.

Digits works just fine on my unlocked S9. All u gotta do is download the tmobile digits app in the app store. Never had an issue

If you dial *#2263# do you also see US bands enabled like band 28, 71, 14???
If so I'd be willing to take my chances and would flash the U1/U baseband/firmware
I'm in a market for dual Sim note 10 plus from overseas. Possible to flash that phone to use tmobile csc (enable volte, wifi calling, etc) without unlocking bootloader or trigger Knox?
As far as I know, the 9750 is snapdragon variant, not exynos

Not without root.
If your goal is VoLTE and Wi-Fi calling on T-Mobile, then there is no need to flash the CSC because T-Mobile has opened up their network for unlocked device. I am getting those functionalities on my dual sim S8+ and also Note 10+ without flashing anything.

So basically call tmobile and ask them to add the imei number into their system? What about Samsung Pay? Will it work without csc?

Actually, both of my phone works without calling in. I think they opened it up sometime last month. Samsung Pay is going to be dependent on your firmware. I am using Australian firmware on S8+ and Taiwan firmware on my Note 10+ which allows me to use Samaung Pay in US (without the rewards program). If you root and flash CSC, Samaung Pay is gone forever due to tripping Knox.

So I'm looking into the same, want dual SIM on T-Mobile service but with Samsung pay and like the us shop Samsung app.
From your last response seems like pay will work but no other Samsung apps like for cashback and award

hi,
how is your experience in term of data connection with Note 10+ exynos on T-Mobile network ? when i check details specification of Note 10+ exynos (N975f) on sammobile, it is missing a lot some of T-Mobile's LTE radio frequencies, https://www.sammobile.com/samsung/galaxy-note-10-plus/specs/SM-N975F/ . even way less than Note 8 exynos LTE bands .
is information on sammobile site incorrect or am i looking at wrong place ?
thank you !

I don't know if the F variant has fewer bands than the N variant but my N is only missing I think band 66 for Tmobile.
Also I'm not sure about wifi calling since that is not something locked down in their end anyway. The device needs to have software and CSC settings to enable it, both of which are absent on at least the N variant and historically F variant as well since neither device was meant for the USA market.
VoLTE works for me, but no wifi calling since both pieces are missing.

I do not have the Exynos Note 10+, I have the Snapdragon Note 10+ but it is also missing similar T-Mobile bands (66,71). You can check the LTE bands on the Samsung UK website and see that the phone covers majority of the T-Mobile bands. Due to the missing bands and lack of proper carrier aggregation support, you might experience slower speed and/or poor reception in rural area. But general usage is not reallg affected unless you are downloading a large file or constantly streaming in 4K.

thank you for your confirmation. i feel upgrading to N975f on t-mobile network will like be in a situation you pay more for less capable device. but it will depends on where you are going to use it most.
OOT, i am wondering why samsuck doesn't make one device with unlockable BL using exynos/SD to rule most (if not all) LTE frequencies, i.e like newer iphone A2104, to capture more customers if there is no technical boundaries

on my Note8 n950fd/s, wifi calling & HD calling (VoLTE) work fine after CSC mod using tekhd CSC DETONATOR INT, tested on t-mobile and their relevant MVNOs (Metro, Simple). so it is just a matter of CSC configuration, isn't it ?

I am guessing if Samsung can have their way, they would push their Exynos chipset everywhere but due to carrier restrictions they end up having Qualcomm in the US and China. I just wish they did all Qualcomm phones like Sony and have carrier aggregation tables from all of the regions available. I believe this is also a problem with iPhone as well but its less relevant for US users - iPhone that can do band 71 does not cover band 28, and only the HK version of the iPhone have physical dual sim.
The good news is that T-Mobile just recently open up their VoLTE, VoWifi to unlocked international so there is no need to jump through hoops (root and flashing CSC) to get those services. Just hoping AT&T would follow before they shutdown their 3G network.

Not just CSC config. If you look at his pack (his is what got me started on the N variant patch I made for the Note 8) there are a few Tmobile system apps that are taken from a US Tmobile rom. The only difference between the F and N in that sense (and the reason his zip wouldn't work on N devices) was that the F had a couple general vowifi files that were absent on the N, and for some reason the N's included digital TV system interfered with the VPN connection that Tmobile wifi calling creates. My N patch basically took the CSC files, the same Tmobile files as TeKHD's patch and those additional framework binaries which were already present in F firmware and deleted the Korean TV thing to stop it from blocking the wifi calling connection.

The reason they don't bring it here is that their exynos modem doesn't support CDMA (Verizon and sprint), whereas Qualcomm's do. Most of the world runs on GSM but since we've moved on to LTE and 5G hopefully this will no longer be an issue in the future.
Also, Tmobile didn't ever have those locked. My Note 8 got VoLTE stock, just no wifi calling for the above mentioned reason. Also for that reason you still need the Tmobile CSC patches to add those missing software pieces even on Pie.

wow... thank you for the education.
I noticed that the CSC mod is for the note 9, Can anyone please direct me to a tutorial on how to set the scs for t-mobile on my note 10+, sm-n975f/ds?
This is the first I was able to find anything about the CSC mod using tekhd CSC DETONATOR INT. Thanks for mentioning it here!
On the Note 10 + (SM-N9750/DS) VOLTE and WiFi Calling work on the stock CSC (BRI or TGY).
Ok thanks for letting me know bro!
Sorry But I just looked through the CSC list and did not see anything listed that contains the phrase (BRI OR TGY)
Sorry I am such and noob and probably do not know what your referring to, ok
I noticed that a few the oem csc have (t-mobile) none are English would anyone of these still work? I am assuming yes, especially because before I put the Brazilian csc I remember glancing at the current firmware that was on the phone and it was not t-mobile, I don't remember exactly I think it was UK Vodafone and it still worked until I got to Brazil I suppose it started to malfunction because I did not have a Brazilian Sim card to use lol

In About Phone under Software Information. Here's mine. It was originally a BRI device but I flashed the TGY CSC on it hence is says TGY, TGY, TGY, BRI. Wifi calling and VOLTE work on either CSC.
Thanks for the reply.
Hmmmmmm. But on sammobile I still do not see TGY OR BRI
May I please ask one last question, where did you get this csc file from?

I need unlocked/dual sim. If I buy the UK variant, SM-F926B/DS, will it work on AT&T network? Will I get 5G/LTE? Will it update? Thanks!
It should. The spec sheets for the phone does not show any variance in the radio's and frequencies they are compatible with in regards to where it's sold other than the ROM's with the carrier configurations pre-configured.
Doesnt the US version have a mmwave 5g antenna the UK version doesn't have?
If correct, how would this affect me? Thanks!
I would be very careful. In 2020 I bought unlocked Note 20 Ultra in Czech Republic and brought it to USA to be used on AT&T network. Unfortunately the 5G bands are not compatible and I didn't get 5G at all. Otherwise the phone works fine, you get LTE speeds and little bit spotty coverage. If you can live with that, you will be ok.
I use an international note 10+ n975f in USA on ATT and my line was shutoff last month because of a new company policy that will be fully in effect Feb 2022. Only u/u1 variants will work on their network...must have volte working and be a device provided thru ATT...not imported. I recommend a different carrier.
These phones will keep working on AT&T after the 3G network shutdown
AT&T will shut down its 3G network and require HD Voice support by February 2022. Check this list to see if your phone will make the cut.

It sucks. They did send me a free note 9, but...I need a new carrier.
Interesting. I’m on an unlocked, dual-SIM, Note 8, N950F which came from Singapore. I don’t remember how long I’ve had it, but I think it’s been around 5 years. It’s not a 5G device, but it is 4G/LTE and supports VoLTE. I think AT&T knows about it because I think I had to provide them with a S/N, M/N, and IMEI years ago. I’d like a 5G device and this one isn’t holding a charge for a full day anymore, but otherwise works fine on AT&T for now. I’d really like to stay with an unlocked, dual-SIM.

In short, yes.
See here for unofficial Lineage build. Limitation is no IMS (volte) though.
I'm considering buying a G970U (US version) with 8GB RAM and paying for bootloader unlock code, see here.
Perhaps best option is to continue work of OP in that thread and build your own with security updates.

Can you tell me what the holdup is with the no IMS / VoLTE development on Snapdragon models, and when this is expected to change if at all, and what forum I need to follow to track this status? I live in the US and I just acquired a S10e G9700U1 thinking I could put LineageOS 18 or 19 on the phone and have VoLTE work. From what I've read, all of the carriers are pretty much mandating VoLTE as a matter of policy for the sake of 4G system management. Ever since the carriers dumped 3G I've been forced to resort to T-Mobile which has an awful footprint in order to keep running LineageOS with my S9 Dual Sim unit as Red Pocket refused to activate Verizon after AT&T shut down 3G and gave me the boot.

I have no idea what the issues are with this though I've seen it with multiple devices so I assume the code stack for IMS services is custom to each device/ROM and come with their own idiosyncrasies/bugs to work out.
Perhaps shout up @klabit87 or other devs in the relevant forums for pointers.
I was extremely lucky and managed to get a free xperia 1 iv as it was refunded/cancelled but still delivered so I'm no longer pursuing a S10e solution.
EDIT: To add to this, the 'holdup' as you put, mostly comes down to the US snapdragon model not having official bootloader unlock support therefor there are very few devs, if any, working on it. The international version uses exynos chipset, the bootloader of which is unlock supported. This is why all the ROMs are exynos only.

Thanks for the insight. From what I've read this is probably between Samsung and Qualcom where Qualcom charges Samsung for VoLTE/IMS licensing and subsequently Samsung can't or won't share the content, and it sounds like it's a lot of effort to reverse engineer. I have a Samsung S9 Duos which is international and running LOS 17.1, but I can only set it up with T-Mobile, and possibly not using VoLTE as it only says on my mobile carrier menu LTE and not VoLTE. From what I read Verizon and AT&T are forcing everyone to use VoLTE and won't let phones without it on their networks. So this makes Samsung custom ROMs in the US mostly useless.
I was considering trying to get a Exynos for the S10e as I love the formfactor and the 256GB memory, but if I wanted a Duos Exynos I'd have to pay 4 or 5 times what my US S10e version cost me, and then I'd probably be in the same boat as I was before with my S9. I'm shifting to a Pixel 5a or possibly a Moto G7 power as those are both reported to work on VoLTE, at least that's what I've heard.
