Okay so I plan on switching to T-Mobile Within a week from now and I want to get a new phone when I switch. I want to get the international version of the S9 Plus but I'm not sure how compatible it is with the T-Mobile network. Will the international version of the S9 Plus work with the T-Mobile network? And also I want it to be able to root the phone because I know the Snapdragon version of the S9 Plus has a locked bootloader. Any advice?

all USA model Galaxy phones with snapdragon processors have locked bootloaders. The F variant is what you want and yes, they work just fine on t-mobile. at&t too.

Hey guys,
I have pre ordered the S3 ( AT&T) version and I will be using it in Canada, now I am not sure if I should cancel my preorder and buy the international version or stick with AT&T unlocked one, I bought it because it does support LTE but at the moment Fido doesn't support LTE ( they said they will this year).
I am worried about the battery life since I read that LTE eats the battery, can I disable LTE? Also what about firmware updates since I am in another country and the phone is for AT&T, would I be able to upgrade to the latest once they release it and how?
I have never used android before and I don't know alot about phone so my questions might be noobish

I don't think the AT&T version is unlocked. I think it is locked to that carrier and you can only use it on AT&T. I suggest you get the international version.

It is actually unlocked, I am worried in terms of updating the firmware and stuff, so if at&t releases an update how can I get it? and also is there an option in Android to disable LTE?
Thanks
What is the difference between the t-mobile variant and the international one accepted that the T Mobile version doesn't come with headphones?
Do I get updates from LG or need to wait for t-mobile to release it also like with a galaxy s6 edge on AT&T? That btw I waited forever!!
There's going to be an international variant to the us unlocked or only carriers?
Tmobile version update is provided through tmobile. But this is xda, I am sure can run international update at some point.
Tmobile version currently got unlocked bootloader.
If you wait a few more there should be some international varient unlocked to work with tmobile, but you wont see them being sold in store....ebay maybe amazon is best bet.
After using an Unlocked S8 U1 on AT&T for the past few years, I decided to get the S9+ (since I don't care for the S10).
I order two S9+ (renewed) from Amazon: the AT&T S9+ model (G965U) and the Unlocked Model (G965U1), since I wanted to see if VoLTE and WiFi Calling would work on my Pre-Paid plan.
The AT&T G965U does work fine with VoLTE and WiFi Calling, but the unit has some nasty fall marks on it, and the volume buttons don't work well, so it's going back.
The Unlocked G965U1 only has a few minor screen scratches, but overall is in better condition than the AT&T G965U, but VoLTE and WiFi Calling doesn't work.
So I'm not sure what to do.
I can clearly hear the difference in Call Quality between the model with VoLTE and without (HSPA calls).
It's too bad AT&T still won't allow VoLTE on non-AT&T Branded Samsung phones.
I have read countless posts on S9/S9+ Firmware and CSC flashing with ODIN (which I'm familiar using) but I can't find a definite answer on if there's way to take an Unlocked S9+ U1 and flash it so that VoLTE will work. I know WiFi Calling won't work, since the IMEI has to be on AT&T Whitelist.
As of right now, the S9+ is on the latest firmware G965U1UEU7CSJ3.
Just to give an update. I was able to flash the S9 Plus G965U1 Unlocked model with the AT&T CSI5 firmware as shown in the Guides section. After that, the S9+ was able to use VoLTE and WiFI Calling on my AT&T Prepaid plan.
I had also ordered a (used/renewed) Note 9, and when I got it, it had Verizon firmware on it. So with it I had to flash the Note 9 first to the U1 Unlocked firmware and then to the AT&T U firmware.
So with both the S9+ and Note 9, I can get VoLTE and WiFi Calling to work.
Now I just have to decide which one I want to keep, as the S9+ was $348 and the Note 9 was $390.
I like the S9+ since it's not as heavy and more comfortable to hold, and it seems like the (smaller 3500mAh) battery lasts longer (not sure why). But I like the features of the Note 9 (S Pen) since I had the Note 2/3/4/5 years ago and miss those features.
I have an unlocked S9 and am on AT&T Prepaid.
I am playing a video about Odin right now.
I was wondering if anybody is using the international T865 on T-Mobile, and if so, how is the LTE signal? I know this model doesn't have all of the T-Mobile LTE bands, but I believe it has a couple of the important ones? I ran an international Tab S2 on T-Mobile, and it worked pretty much just fine in Los Angeles. I was kind of curious how this might work now, if the network has changed since then or whatnot, and then how the merger with Sprint might affect it in the near future. Any info is appreciated!

I attempted to flash the international T865 on my unlocked T-Mobile S6 LTE with Odin and a Patched Odin but in each case it failed.

Yeah I don't think that works. Have you tried putting a smartphone sim in your T-Mobile S6? I'm sure the system will recognize it as a tablet and not a phone. That's why I want to order an 865 international model. But then again I guess I might look into how much it costs just to add some tablet data to my plan.

I have a smartphone sim (no difference than an normal sim) and get mobile data which allows me to use the phone when WiFi is not available (I don't want to use my phone as a hotspot). The T-Mobile LTE tablet cannot make phone calls or text but can use the text and call on other devices option on Samsung phones which allows you to use the Tablet using your phone number.
On other samsung devices the US models use the Snapdragon chip while the international model uses the exynos chip which can easily unlock the bootloader and root the phone or tablet. I understand that the S6 LTE tablet is using only the Snapdragon chip worldwide so rooting may be much more difficult. However the international version should have the OEM unlock available so the bootloader can be unlocked. Normally I only get the international versions and root, but if is getting more difficult each year to root the Samsung devices. I bought a used S6 LTE and am happy with my tablet.

So you have a smartphone sim in your T-Mobile Tab S6 LTE, and can get unlimited data? Is it a T-Mobile SIM or another carrier? I tried that some years ago with a different tablet and it didn't work because the system recognized it as a tablet and not a smartphone. That would be cool if it works though, I don't care that much about calling and texting, but unlimited data would be cool.
I like the international models too because they can be used like huge phones lol, but they don't have all of the T-Mobile LTE bands, but I think they have enough that it works okay.
I am thinking of getting an S21 from AT&T because of the deal they have right now, but I don't like AT&T bloatware. I'm a noob when it comes to phone firmware and such, so I'm not sure what is or isn't possible.
My understanding is as follows:
Carrier unlock is possible via AT&T website to use other carrier SIM cards.
Bootloader unlock is not possible on AT&T devices (starting at V2 seemingly?).
I'm just not clear if you need an unlocked bootloader to flash the stock S21 ROM on an AT&T device. If not needed, what is the point of unlocking the bootloader, just for root?
Any clarity is appreciated.
You can use "patched ODIN" to do flash "U1" firmware, which removes bloatware.
Not sure about the bootloader, I think you're correct on that.
I flashed an Xfinity Mobile S21 (carrier unlocked by them) to U1 but so far the phone is refusing to use the proper carrier settings for VoWIFI (I have a VZW sim in it now). It worked for 1-2 weeks previously. Everything else seems to work properly including VoLTE.
I'll probably switch back to Xfnity Mobile to get VoWIFI working again.
Thanks for the response.
can I ask something related? I got my Samsung S21 from Amazon unlocked and I'm in International market. the phone has esim capability but it's locked up. my question is (can) I flash international firmware or let's say the one being sold in the middle east? I'm stuck with single sim which is pretty annoying. what do you guys recommend

My understanding is that the international firmware is not compatible with the US phones because the US version uses the Qualcomm Snapdragon processor, whereas the international phones use the Exynos chip. I think you're stick with single SIM, unfortunately.

the snapdragon version is only sold in the US solely?
"International and Korea models of the S21 utilize the Exynos system-on-chip, while the U.S., Canadian, Chinese, Taiwanese, Hong Kong and Japanese models utilize the Qualcomm Snapdragon 888."
