Hi all,
I have a US bought S21 Ultra that i bought and used in the USA. I have now moved to the UK. The g998u1 Is not able to use UK 5G bands. My question is whether flashing the phone g998b or g998w will enable the bands that i need or, is there a physical difference on the phone that will negate this?
Thanks in advance.

Devices sold in different regions often have hardware differences. Samsung in particular is known for doing this. I would think that it would be generally cheaper to use one radio chipset across all markets and just use software to define its capabilities, but this often isn't the case.
https://forum.xda-developers.com/t/...22-series-including-sub-6-and-mmwave.4488435/ works. Just skip the steps you don't need (i.e., if your csc is xaa, there's no need to change csc).
It works on my u1 xaa and other than band 28 for 5G, all the bands are there.

The next software version could always break this. Do you ever use it with AT&T or Verizon or their MVNOs sims or esims? Does the *#73# still work for band selection for them? Thanks

Hi!
So I've bought a Samsung S9 Duos recently and to be honest, although I like the phone and have been on a Samsung streak for the past few years, I'm getting seriously tired of their country dependant shenanigans. Because I live in Canada, when I buy a Global phone there's a bunch of stuff that either doesn't work or does only partially. And because the Canadian model is a SD proc, not an Exynos, it's an absolute nightmare to switch CSCs and get everything working right...
I hesitated long and hard to get a P20 pro, but the fact it wasn't available anywhere in Canada made me nervous. But my carrier (Rogers) recently announced it so, being really tired of this Samsung ****e, I'm considering returning the S9 and getting the P20 pro (even if it doesn't have a lot of stuff I like such as the headphone jack, SD card and wireless charging).
TL;DR
My question is, if I get an international (dual SIM) model of the P20 pro, is it going to be different than the Canadian one? Is there an equivalent of CSC codes with Samsung that I have to worry about, or can I assume it will be the same phone and I just need to activate it to get carrier specifics?
Thanks
I'm not an expert, but before I bought my P20 Pro, I made sure that it worked with the AT&T's network frequency bands. Each network has different bands and if the phone doesn't support the band, it won't connect.

Thanks for the input. I checked the bands for sure, and they are covered since it will be sold on my carrier soon. I guess what I meant is more the model itself, if there are variants per country or if we (Canada) are getting the same global version.
You see I come from a Samsung user's background and they have these silly country codes that dictate what you can use and where. I'm not sure it's related, but I found that even if on paper all LTE bands are covered with my S9, it still has shoddy reception compared to a Canadian S7. I could try to flash my CSC code to the phone, but a) it's complicated and risks bricking the phone and b) since the Canadian model is NOT the same as the global one, my CSC cannot be applied to this phone no matter how hard I try...

FunkyHuawei offers a rebranding tool, which changes the region of the ROM. I used it because I bought mine from a Chinese e-commerce website. I rebranded to European region.
I couldn't find anything about International or Global versions of the phone. I know they are region locked, but the rebranding tool will fix that. You can also flash a firmware from FunkHuawei or use HuRUpdater tool from TWRP custom recovery.
I have used both tools, and had 100% success.

Cool thanks, I'll see how this could help me out. I'm giving my S9 one last chance but short of that, I'll cough up another $1000 for this phone; I just don't want to end up in the same trap!
Hello,
What model should / would we be able to get to work on Verizon that can have an unlocked boot loader, TWRP and install custom roms.
My understanding from reading here is that no US model will work. What foreign model is best for getting the above done on Verizon.
Its about time to say goodbye to my note 4.
Thanks
i am going to rock an unlocked USA model on verizon, not sure there is one that will work on verizon with unlocked bootloader

Your only possible option is the 9600 since its a snap and im not 100% sure it will work
So Id suggedt researchung heavily before buying

Ya I spent a few hours trying to find anything.
Only thing I was able to see that might work is a portorican phone but saw somthing that we needed some kinda firmware flashed first?
So made this post in hopes someone had an idea on how we could do this and make sure it works good.

I have a friend with the Latin American S9+ Snapdragon that's bootloader unlocked on Verizon. He told me he just flashed the Puerto Rico firmware to get signal. I'll be trying the same thing as soon as the Odin files are up on Updato for the Note 9 Latin version. I'll update when I have some real results.

And in theory it should yes but as I am not on Verizon and dont know anyone who is i cannot say for sure 100%.
Again....you will need to do some more in depth research on your own but someone posted a chart with the models and LTE bands here somewhere today so start looking for that post...very useful. Id i come across ill link it here

Would the SM-N960UZBFXAA Unlocked from samsung's site work for verizon?
Also when they say unlocked is that the boot loader? or just to carrier?

The Samsung UNLOCKED = "Unbranded" i.e. generic software. It doesn't mean that its bootloader unlocked.
When using the USA unlocked/unbraded GS8/Note8/GS9 there were a few limits on the USA carriers... While calling/data/sms works, Carrier specific features like Wifi Calling, VoLTE, Visual Voicemail, etc. varied. I expected that would apply to the unlocked/unbranded Note 9 too. For unlocked on ATT, there is a VVM app in the Google Play Store that works, but if I recall correctly, Wifi Calling and VoLTE didn't work. For Verizon, at first there wasn't a VVM app, but there is one in the GALAXY app store now that works (and now will auto install when Verizon sim is in the phone if you open the Galaxy App Store). VoLTE (aka HD Voice) works. Wifi Calling and Verizon's Video Calling features do not work. T-Mobile seems most compatible with the Unlocked/Unbranded device as all of its features work out of the box. with a T-Mobile SIM, except you have to download the VVM app from Google Play Store.
Now that my Unlocked (aka Unbranded) Note 9 from Samsung USA arrived, I can confirm that just like my past unlocked/unbranded Galaxy devices on Verizon.... Bootloader is locked, SIM is unlocked. Wifi Calling and Verizon's Video Calling don't work. For Visual Voice Mail there is an app in the GALAXY App Store (that will install after you insert Verizon SIM and open the Galaxy App Store). And the rest works just like my Verizon branded GS8/Note8/GS9 devices.
Tethering check on unlocked version?

Does your version check for hotspot eligibility? In the past the unlocked versions have not checked (Note 8, etc.) but want to be absolutely sure with the Note 9 before ordering. Thanks.
All the research I've done points towards the 9600 (Latin America or wherever else the model is sold) being the best choice for verizon. The only fly in the ointment is it does not as far as I can find support band 13. I have seen threads in some other forums about enabling bands but don't know if it would be possible. Hope that helps.

I don't know, and can't check because my personal Verizon line is a current unlimited plan that includes tethering.

It's probably just the firmware that it ships with. On the Latin s9 and S9+ you just had to flash the Puerto Rico firmware to have all bands and Volte working. I'm thinking it will be the same way for the Note 9. I'm just waiting on the Odin files to be released and I'm purchasing one immediately to try.

? just buy a exynos F or N or SD 9600
problem solved.
After a bit of googling and searching amazon I was only able to find AT&T compatible international versions, I remember someone saying the other CDMA phones worked on a different band then the US Verizon bands. When I google Exynos CDMA I get told Exynos isn't compatible with CDMA because the radios for it aren't installed on those phones.
Not gonna happen
There is no talk of a Developer Edition and is unlikely as none of the recent Notes have had one. The Exynos models don't have the proper LTE bands for Verizon. The N9600 is a Snapdragon, but I'm not sure if it runs the correct bands for Verizon either.

Where did you get your SM-N9600? The ones listed on Amazon claim to be the 9600 international version but they all say GSM only no CDMA.
EDIT: I found this: https://www.techwalls.com/samsung-galaxy-note-9-sm-n960-model-number-differences/

Awesome, thanks for the heads up, I will make my way right on over there and get me one on Thursday when I get paid.

Carrier Aggregation combinations are compiled to modem firmware so you can't edit these. To update these need source code of modem firmware and then need sign key to sign firmware otherwise your phone modem will brick. On cacombos.com have listed hardware defined combinations.

you ever figure anything out?
Hi all. I have the a few sm-g998b phones, rooted with magisk, and I am a bit confused about which CSC I should flash to the device (SAMKEY). I ordered the phones from Singapore and need them be more compatible with USA verizon and USA tmobile. Only using one sim per phone. Which CSC should I replace the current SIN csc with for each, and is there anything else I can do to make these phones play a bit nicer in the USA? I am currently having issues with no 5g, poor wifi calling, no updates, etc.
1. Avoid SamKEY. Do your own work.
2. Flash the HOME_CSC, or the CSC of the firmware of the carrier. HOME is usually a safer bet though.
You're going to have issues in the US until you flash the proper CSC. AFAIK, every S21U has all radios, but the CSC activates the correct one.
For the absolute safest, download the TMOB stock firm, and flash the HOME_CSC (as well as the BL, AP, etc), then put the Tmob SIM in after boot.

Why would you aquire the Exynos Global variant knowing your service provider isn't optimized for your firmware? Did you save money? If so I hope saved a lot otherwise it was a poor choice. Your best option is keeping the stock SIN Firmware, at least you'll get timely updates. You MIGHT get Wifi Calling and VoLTE enabled but forget about 5G and Carrier Aggregation.
Missed that you mentioned an Exynos variant. Yeah, you're ****ed. Exynos is not compatible with US bands, or at least aggregate banding.

Unfortunately, these phones are company. we needed root for some applications.
*don't use SAMKEY
This is a bit tricky because US is Snapdragon-based.
My best bet would be to factory reset (don't forget to backup) and flash a multi-csc Exynos ROM (OXM). This would detect the most compatible one for your US sims.
I would suggest getting the XSP for Singapore because that's the unbranded one.
Other than n71 5G band for US Cellular, I don't think you'll have much issues.

"This would detect the most compatible one for your US sims" Nope, that's incorrect, Exynos Global variants aren't able to detect the most compatible US Networks. It's apples and oranges, there is zero integration for US devices.

The Exynos variants are Multi-CSC Devices, mainly for Europe, not for the US. The SM-G9980 isn't a Multi-CSC Device unlike some US Models, it's Dual-Sim. In Settings under Network Operators you can have the device select the "Best Network" but it isn't analyzing call features, it's only matching the network with the Active CSC (SIM Card).
Bro,
On the stock phone dialer key in
*#2263#
You will see the bands the 998b supports.
Now u need to check on the networks u plan to use in the US what bands are used. Not sure what u plan to do but these exynos phones should be able to roam into the US with voice n data services. Not blazing gigabits but one should be able to roam globally with these phones.
