Tmobile variant on ATT - Samsung Galaxy S10 Questions & Answers

Hi all,
Going to be purchasing a Tmobile Galaxy s10 for my girlfriend and wondering what, if any, drawbacks there are to buying a TMO variant but activating it on ATT? I'm pretty sure wifi calling won't work, but what about updates? The splash screen will still be TMO I would assume and then would it still be on the TMO update schedule? Has anyone done this? Thanks.

First of all, I never buy from the carriers anymore. Bloated software, ads, etc. & LOCKED BOOTLOADERS, drive me nuts.
I would buy the International Unlocked Model. If you are looking for the S10, the SM-G973F is the international version. AND the local USA carriers will not sell you this model because they want you LOCKED on to their carrier!
But you can buy from SWAPPA or Ebay or AMAZON. I have the international S10E with the fingerprint unlock in the Power button (no problems with installing a glass screen saver).

I'm curious as to why you're not just buying an unlocked model if wifi calling doesn't matter. In reference to another rant posted, I doubt she will need to unlock the bootloader so I see no need for the international version off Ebay depending on what country she'll be using it in. On what you're asking, yes someone has done it I believe.

Question about U vs U1 variant before I sell

Hello,
I am planning to sell my Sprint Note8 online soon. I have the phone unlocked (and confirmed that it works on AT&T with a friends SIM). My question is that I'd like to advertise it as just the North America Unlocked version to reach a larger audience and hopefully get more money. I am pretty sure there are no hardware differences between the N950U and N950U1 variants. So my thinking is that if I Odin flash the XAA N950U1 unbranded firmware onto the device then it would be identical to a phone straight from Samsung. That said, I'm not 100% sure and of course I don't want to falsely advertise. Can anyone conform for me whether I am right or not? Obviously I will market as "Sprint - Unlocked" if there are any differences at all.
Thanks
I think it would be safer and better for the buyer if you flash whatever Network they want before you ship it.
don't update this app!!

Be sure to follow the switching carrier guide to change code to specified carrier to get rid of lingering Sprint stuff if you want them to have true stock experience...if you change carriers, that is...even if you do xaa

[Q] Which version should I get?

After a few years with my Samsung Galaxy Note Edge (AT&T) [SM-N915A], which wasn't bad until the last 6 months and then the inability to root it made it worse, I want to make my next upgrade worth it. I'm waiting for the 500 Gb version, and I want to be able to root it.
Of course, my eyes are on the Note 9, but which version should I buy?
International (SM-N960F)
International (SM-N960F/DS)
Unlocked
AT&T
T-Mobile
Sprint
U. S. Celular
Verizon

International because it gets updates faster
And it has more development support (custom roms, kernels, etc)
Also ive been in this situation with the at&t note 4 ?
Looks like at&t doesnt want us to root our devices
So dont get at&t

Simply put, If root is what you seek on Samsung devices these days, Don't get any of the U.S. carrier editions of the phone.
All of the U.S. Samsung devices ship with Snapdragons and Samsung has ultimately decided to lock all bootloaders on them as well, That's not to say that a Dev won't attempt to work on atleast a root method for Snapdragon devices but with a locked bootloader you won't be able to do much.
Samsung's also implemented a rather interesting tactic to deter rooting on Snapdragon devices, When they're rooted, The device will no longer be able to charge to 100% and instead will default to 80% only.
This can be demonstrated on the S8 and the Note 8.
The S9 Snapdragon U.S. variants still don't have root to this day, When and if it ever does, that same method may be usable to figure out the Note 9 as well, But don't get your Hope's up.
Now for the international and Unlocked devices they ship with an Exynos and subsequently unlocked bootloaders which allows for the creation of Mods, Roms, And the various other things most people root for nowadays.
All in all, You want an Exynos equipped Note 9, Hope this is useful for you.
Thanks,
Almost right after the the post I came upon this article
https://highonandroid.com/android-deals/best-deals-on-galaxy-note-9-new-galaxy-phones/
it goes a bit more in depth, covering GSM vs CDMA, when and where to buy it.
It seems that the Latin America Galaxy S9 and S9+ (SM-G9650) both had Snapdragon processors with an unlockable bootloader. You could then Odin firmware on them to be able to use them on Verizon, At&t, and T-mobile. I hope they will release a Snapdragon model of the Note 9 as well in Latin America! I need an unlocked bootloader on Verizon for sure.

It doesnt matter anymore which type of note 9 you get, because there is gonna be root protection where imei and network flies if you root, like the a8 on oreo
And also i agree with you, US carriers (especially at&t) prevent root all the way up to the fact that you cant root at all (the at&t note4 has no root but all the other note 4's have root)
will an international work on USA carriers?

I'm interested in the unlocked version instead of the T-Mobile, but I've read that the bands are not the same and wifi calling doesn't work. I'm over flashing ROM's, so that isn't an option for me. I'll probably get the carrier branded one to make sure I get the 600 band and wifi calling.

I can unlock the phone here for free. Why go to Canada? I buy my phones for cash. I'm not stuck with a locked phone. The only reason I would go with the non-branded unlocked phone is the lack of bloatware.

I have the old gUDP plan so I need a phone that does NOT check for hotspot eligibility. I understand the unlocked Note 8 did NOT check, so it's likely the unlocked Note 9 would be okay as well. So I'm definitely stuck with the US unlocked version, right?
Geez, I kind of hate both Verizon and Samsung, but I want to stay on gUDP and want a good phone that will work for me out of the box.

My understanding:
Verizon model WILL check for hotspot eligibility and thus won't work for us.
International unlocked models will not work on Verizon's network.
Therefore, we're stuck with the US Unlocked model. It has a locked bootloader, and thus may never be rootable, but will work with Verizon and NOT check hotspot eligibility.
To be clear, at this point I just think it's very likely the US Unlocked model will NOT check hotspot eligibility. I will probably wait to confirm that before I pull the trigger.

How to buy the right Note 9 for the US

I'm considering buying a Note 9. I usually buy a year old model of a flagship phone when the prices come down. I see lots of Note 9 phones on amazon for reduced prices. It appears there are several different models and the descriptions from the sellers are usually not clear.
I saw another thread that said all the US versions were the same hardware. Can I buy an unlocked Sprint, Verizon, AT&T, or T-Mobile phone and use it on any carrier? I will mostly be using AT&T and T-Mobile for now.
How could I tell if a phone is the US non-carrier branded model?
Can I flash a more universal ROM to a carrier branded phone and get rid of the carrier bloatware? Will the universal ROM still pass MDM security checks so I can use it with my company's MDM (Intune)?

Buy the USA unlocked model U1. You can then flash the USA T Mobile or AT&T rooms should you wish.
However, I also read that AT&T doesnt allow full network speeds for non AT&T devices. Maybe someone with an unlocked U1 on AT&T can chime in.

I have been running unlocked bought directly from Samsung phones since the note7 and I use them on AT&T. I am in Wyoming, and have noticed no loss of speed. I have Verizon for work phone and my unlocked phones is always faster in speed tests . Not very scientific buy my experience.

Question Shipping from Samsung_US to Canada (Unlocked version) /any possible method?

Hello everyone,
Could you help me answering my questions?
I'm planning to buy Samsung S21 Ultra, so I was searching for good prices here and there...
I found out that on Samsung US, it is much cheaper (Unlocked version), moreover, you'll get 250$ credit value to buy other accessories, while Samsung Canada is way too expensive without such promotions!
I tried to place the order through Samsung US and to type the shipping address to Canada .m.but unfortunately it wasn't working!
My two questions as following:
1- Is there anyway to get the S21 Ultra to Canada from Samsung US?
2- I heard that I might face problems in connection compatibility (even with the unlocked version), especially the 5G as it won't be compatible with the Canadian courriers ....so is that true? Will I face any problem if I buy S21 Ultra from Samsung US to Canada?
Will appreciate your replies ...
Thanks
Depending on your carrier in Canada, Wifi Calling and VoLTE may not/will not work. Here is a long thread about purchasing from the US etc. This will answer all your questions:
[Samsung USA] Samsung USA S21 Trade-In Deal Thread - RedFlagDeals.com Forums
i have the W version with the US U1 software on it (I love ODIN) and works it great on Telus for 5G (except the Wi-Fi calling; Telus asks for your number and then it never connects but I also have a partner account so maybe that is why). On Freedom Mobile/Shaw Mobile with the U1 software, everything works (except 5G as that is not available for everyone yet).
Thanks
May I know which re-shipping company had you dealt with? Any recommendations?

Question Question on unlocked S21 Ultra 5g bought from Samsung

So here's my question. I was waiting for the T-Mobile version of the s21 ultra to be in stock in the 256gig version, but it seems like that is taking too long so I had purchased the unlocked version. Yesterday when I went into the T-Mobile store, I was told that it wouldn't be able to pick up 5g and a lot of the phone itself wouldn't be compatible. Does anyone know if this is true? Sorry I know I sound like a Noob because I am, but I'm just a bit worried. If that's the case I see about people flashing stuff. Would it be possible to flash say the T-Mobile stuff to the unlocked phone so it would work? Sorry for writing a book, just wanted to be thorough. Appreciate any feed back or answers.

They either lied to try and sell you a T-mobile version or they don't know what they are talking about. The US unlocked model works well with all the US carriers and has no issues picking up 5G and even supports WiFi calling.

I have TMobile and an unlocked s21 ultra. They work perfectly together. No issues whatsoever with 5g.

Dude that's awesome, I'm feeling way better about my purchase. Thank you for replying and letting me know. I appreciate it.
I have a S21 Ultra unlocked and carrier is TMobile, no problem so far.
T-Mobile has the least number of issues if you bring-your-own-device. It's Verizon that's a real PITA.
I'm grateful for everyone posting and sharing their experiences and uses. Thank you to everyone. Appreciate it.
Go to a different store. They lied to you. I bought mine from Amazon, it's the unlocked 128gb version, (the 256gb wasn't in stock during the sale. They both priced the same) and it works without a problem. T Mobile 5G works really good on it.
I'm getting 5G via T-Mobile on my unlocked S21 Ultra direct from Samsung. That shady store or salesperson straight up lied to you, they are ignorant about unlocked devices, or both.
I want to change IMEI of Samsung galaxy s21 ultra 5g
Changing of imei is illegal in most countries (if not all). You will not get any help with that on XDA...
As others have said, this isnt true.
One thing that is (ior certainly was a couple of years ago) was that Three didnt allow non three branded handsets to connect to their 800MHz supervoice service, which IME made a huge difference in the LTE days
