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?

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 ? :confused:

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 :confused:

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.

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!

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 :confused: lol

On the Note 10 + (SM-N9750/DS) VOLTE and WiFi Calling work on the stock CSC (BRI or TGY).

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 :confused:

May I please ask one last question, where did you get this csc file from?

    I used the normal Odin like I used to root because, I think the patched comsy version does not have a csc button to push, should I be using a different patched Odin, if so please let me know what version?

    This is the newest patched Odin.
