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

Could I buy n975f/ds (this one should be exynos) and flash tmobile csc?

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

That's correct, Samsung Pay registers all my US cards but no US rewards program.

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 have an Exynos S20U that is LTE (or 4G) and i would like to enable it to 5G. Samsung for some reason decided to keep the 5G module on all phones but disable it on some and i find that unacceptable on a phone I paid 1400$ for.
I would like to see if this is possible (and also to change the text on the boot screen).
All input is appreciated. Thanks.
sorry all s20 Ultra's should be 5G enabled?. Please ensure your phone is the correct one for your country/region and running the correct CSC code for yr network. make sure your network supports 5G and your tarriff is active with 5G etc

Some countries in Europe get the LTE version which still has the 5G modem inside the device, hence the identical model designation but it's not enabled. Even on the boot screen it says ''LTE'' instead of 5G, and on the box it doesn't even tell you that it has 5G capability. An idiotic move on Samsung's part tbh.
That's why i was asking if i could somehow bypass that and enable it manually.

The only way to know that for sure is to tear the device apart and check if the 5G antennas are present, there is supposedly no other way to know.
For the bypass part, you need someone to actually understand how that modem works, create a custom firmware for that modem (which I guess is different for Exynos and Snapdragon models) and then enable 5G.
All of this will require significant reverse-engineering effort to work at all. You won't see a 5G enabler soon. Also, it will 99.9% require unlocked bootloader AND root, so say goodbye to knox.

I've actually seen a teardown of the Ultra i'm using, and it has the exact same 5G modem as the advertised Exynos 5G G988B Ultra.

Wow didnt realise there was an lte/4g only model of the s20 ultra. It doesn't make any sense is it much cheaper than the 5g version? What market is it sold in?

As far as i know, Indonesia and some parts of SEA, and parts of Europe (Central and Eastern). Could be more widespread but in essence it's an exactly the same phone, same model number, identical internals as the 5G version, just with the 5G modem disabled for some reason. It doesn't cost a penny less.

it is possible Samsung locked the 5G in S20 Ultra sold in Indonesia because Indonesia is still far away from the implementation of 5G.
Quoted from The Jakarta Post, "We'll be able to implement 5G services no later than 2022," said Association of Indonesian Cellular Operators (ATSI) chairman Ririek Adriansyah.
I guess Samsung is trying to save your phone battery from trying to search for 5G bands when it doesnt exist in Indonesia.
Try installing this app from google play store. https://play.google.com/store/apps/details?id=com.ray.samsungbandselection
If your phone has the antenna, it should show up here.
UNLESS...... samsung added the antenna but didnt load the antenna drivers into the firmware.. but that would be a stupid thing to do.

That's a good point but it seems strange as i live in Europe, in a country which promises 5G coverage by the end of the year (not country wide, but in major cities). Do you think Samsung could eventually release a patch to enable it?
Also yes, Samsung indeed added the antenna but there's 0 drivers.

A CSC based switch is definitely possible, if you switch to a CSC from a country where the 5G model is officially sold, you might be able to use it, but no way of knowing for sure without visiting that country, switching the CSC and inserting a 5G-ready SIM card.
Has anybody tried and tested this?
What if you install a S20 5G firmware instead of the default one?
Please tell anyone how to enable 5g in S20 ultra Indian version.
I have a bootloader unlocked, rooted Galaxy S20 Ultra SM-G9880 (Hong Kong version) that I am using on T-Mobile. However, I had some doubts about how it interacts with the various bands.
The phone does not support some of T-Mobile's LTE bands, and it does not seem to support any of their current 5G bands. Is there any way to change this with CSC changes or any other trickery?
Would AT&T be better for any of this?
When I use the Samsung band selector app, I see that NR B41 is supported. This is the Sprint spectrum that T-Mobile is repurposing, correct? Does that mean additional 5G and LTE coverage once the rollout is complete?
Another user was having problems enabling carrier aggregation. Is there a way of doing this?

You can't change to a US CSC on your device. Some users are reporting 5G works only on SIM2. Carrier Aggregation isn't compatible in the US with the SM-G9880. I have the Hong Kong variant on T-mobile and 4G LTE works fine.

Would you happen to know if our imei works with 5g on t mobile? I just switched last month from att. On att, you would have to call and give an att imei in order for 5g to work and I'm wondering if t mobile is the same way or if it works out of the box with our imei.
Also, I have an SD card and seems like I cannot have a Sim on slot 2 and an SD at the same time, do you happen to know if an esim will get 5g?

That's a question for T-mobile. It's not a question of your IMEI, it's whether or not your device's available 4G and 5G bands are compatible with T-mobile. I don't know what model you have but if it's a US model eSim isn't available on S20 devices. Only Exynos devices have eSim capabilities.

I have the same model that's been on topic... The SM-G9880...
SM-G9880 isn't eSim enabled, only Exynos variants offer this. 5G may work, take it to your local T-mobile store and see if they can set it up. Often times information coming from a CSR over the phone isn't reliable. If it worked with AT&T on SIM 1 T-mobile it MAY work as well however many users have stated it only works on SIM 2. Even though T-mobile's 5G network has a larger coverage area they can't match the speed of AT&T's mmWave network.

If you root the device I suppose it's possible to override an eSim block on the SM-G9880 but I'm not aware of anyone achieving it. The only Snapdragon variant which offers eSim at this time is the Galaxy Fold. I don't understand what the value of eSim is on a Dual SIM device. Even if you travel to a different country it's a simple choice, keep the SD Card in or use both SIM's and rely on internal memory for storage.
Did anyone try using BRI CSC to see if CA works in the USA?
Hi,
I haven't been able to find a clear answer to this, but does the international S20+ work on AT&T's 5G and mmWave network? From what I can tell the phone has RF support for AT&T's 5G bands including mmWave (n260), but does the phone actually register on their network?
I'm coming from the S7 where I was used to flashing a CSC or OMC for AT&T in order to get VoLET and WIFI calling. Is there ATT CSC or OMC support for this phone yet particularly for 5G and mmWave support? I couldn't really find anything.
Thanks!

What don't you understand? You're looking for clear answers since you really can't find anything. First you need to realize ATT Firmware including their CSC isn't compatible with your Exynos SoC. Secondly, why not ask the Service Provider in question (ATT) since they're best suited to resolve compatibility issues?

Maybe I should have been more clear...What I'm really asking is if anyone currently has an unlocked international variant and is running it on AT&T, and if so, does it connect to their 5G mmWave service?
Its been my experience that the people who work at ATT stores don't know anything about anything. So no I'm not going to waste my time asking someone who will just try to tell me what I want to hear or flat out say no because they don't know what their talking about.
Yes a carrier's CSC is technically not compatible with an international unlocked phone but it still works. There are a whole bunch of people running custom or stock CSCs on non-carrier hardware, myself included.

Your device isn't compatible with ATT mmWave regardless of the CSC or FW. Nor does it matter that your device operates on the same 4G and 5G frequencies ATT engages. It has to do with ATT Protocols which restrict functionality to select devices.
ATT is by far the worst when it comes to compatibility alignment for Non-ATT devices. If call features, carrier aggregation and services are a priority then stick with your service provider's branded device.
Got a steal of a deal on a Note 10+ 5G 256GB brand new never used. I'd like to use it in the USA on Verizon. is this not possible? is there a dial code to maybe enable cellular bands that are disabled? Its running LineageOS 20.0 already with Root.
