Anyone out there doing this? May change from ATT to TMOB and want to know if anyone has had success doing this as the bands aren't exactly the same.
Im receiving my unlocked note tomorrow and im on tmobile, i asked previously if any special setup is involved and the responses ive got was put your sim and you are good to go!!

I'm doing this right now and it's been good. I flashed the unlocked firmware and theres been no problem. I don't think volte works but I don't mind.
Did you have to flash a different firmware?
Try switching carrier thread if you have any issues...it cleans off previous csc code and allows for clean install of other carrier firmware...worked from Verizon and Sprint to T-Mobile...and back to XAA/XAA/XAA without ANY residual carrier stuff...

Hello everyone, based on extremely poor ATT coverage in my area comparing to T-M I plan to purchase AT&T Note 3 SM-N900A, unlock it and use with T-M SIM card.
Would I face any issues in terms of unlocking and data coverage?

Soooo.... why would you want to buy a N900A. I feel like we are missing some piece of info. What about getting the N900T and having the best of both worlds. The modem on the N900A is more restricted than the Tmobile version (surprise surprise).

Really? I'm glad I asked prior to spending the $$$
Other than the firmware the phones are identical, correct?
Right now I borrowed Note 2 AT&T SGH-I317 and it seems (to me) to work OK on T-Mobile.
Yes, the Note 2 was one of the last phones before ATT went crazy and started locking down everything. You could enable the AWS bands of tmobile on the ATT note 2. Here is a guide for the N900T if you go that route. Many of us are doing it. You can use it on either carrier. If you are going to use tmobile you might as well use the wifi calling also. It's free and only on the N900T.

Thank you! But the guide is for using T-Moblie phone on AT&T network, I have the opposite.

I know. My point is that the N900T works perfectly on ATT and Tmobile. It works on both carriers and is the most up to date. The N900T has had J7 for a week where the ATT model just is now getting J5. The carrier specific features like wifi calling are not on the N900A.
Also if you read in that thread I list the fcc bands that are active on the N900A compared to the N900T. They are more restricted than the Tmobile version.

Ok thanks again, all I need is the best deal on either used or new N900T. I don't see any listed on Amazon and pricegrabber brings up three crazy deals price of $700 with signing up with T-Mobile

Yes, you will definitely be happier especially if you are wanting to use it on the T-mobile network.
att sim in n900t? HSPA+<E?
Sorry for barging in just a quick question and this thread seems to be the most logical place to ask. Anyway, I have AT&T and just got the Note 3 n900a. If i got a T-Mobile version n900t and put my AT&T Sim in it if i unlock it, will i be able to use it with AT&T's data like hspa+ and LTE or will i just be limited to EDGE. Only reason i ask is because like you say AT&T is going nuts with locking everything down and Im sure its going to be a pain in the a** for the Devs to unlock the bootloader so we can (when it comes) flash custom recoveries and roms. Just like with my att galaxy s4. I was happily rooted and at the time i didnt flash a rom yet i was waiting to find one i like. (mind you i was on the MDL build) and as forgetful as i am just being stock rooted i never froze the samsung software update and it updated to MF3 build and wasnt able to fash a recovery. so i unrooted, reset flash counter and did a warranty exchange and was lucky to get one on still on the MDL build. the second i got that i rooted flashed CWM recovery and flashed a custom rom so it wouldnt update on me. I just dont want the same situation for when the devs unlock the bootloader and get a flash able recovery so just thinking maybe a tmobile note 3 with my att sim may be the way to go to avoid that. lol Not like the note 3 needs any custom rom with the beast of a phone it is but sometimes i like to switch up and use stock/aosp android.
Thanks and sorry for the paragraph here and my apologies if i asked in the wrong spot,
Dave

This thread is huge but hopefully has everything you would want to know on the topic. Look at the first post.

OK guys, somewhat of a newbie, so try and give me a break. I am looking to upgrade to a Galaxy S8 and came across an unlocked T-Mobile S8. Can I flash the AT&T firmware to this phone? If I run the T-Mobile firmware on the AT&T network, I assume I won't get any updates? What about the radios? I know both are GSM networks and with both the AT&T and T-Mobile S8 sharing the same model number, I assume this won't be a problem.
Anyway, any guidance is appreciated.
Thanks!!!
I'm looking for the same answer
I believe if it's unlocked from t-mobile, all you have to do is put your sim in it. Given they are both GSM and all the relevant info is stored on sim card and not the phone

you will still get updates from t-mobile. i am using a note 4 unlocked from tmobile on at&t for about a year, getting my s8+ tomorrow actually. the only thing you have to do is add at&t apn settings which are easy to find if you google. i would like to know if its possible to flash another carrier and then flash back to the phone's original carrier tho
Im thinking about buying the s8+ verizon phone from samsnug direct as they have a great trade in program currently
my questions are..
Do i have to be on verizon to get updates? Im thinking of taking it to straight talk
Can i flash an unlocked firmware of this and the phone still remains working fine?
DOe sit have bands for tmobile / att ?
They are supposedly the same exact hardware. Some of us flashed the combination firmware to be able to unlock the LTE bands. If you stay on Verizon firmware, you will not get any OTA's. However you can use their update software as well as Samsung smart switch software to do manually updates. Plus you can always download VZW firmware from places like Updato.

I am interested in buying the galaxy s8 plus for verizon as well since i will be getting a good deal but I use and would like to stay using AT&T service.
I know that the verizon model is GSM unlocked and could be used with AT&T. I would need to update the APN's to make everything work correctly.
My concern is if it will pick up all the AT&T bands if the phone even supports all the bands. You stated you flashed the combination firmware to unlock the LTE bands.
Would that be exactly what i would need?
If so do you have a link ?
after posting this question I will be doing a search as well.
TIA.
You should just flash the Att firmware then. Check the switch carrier posts for detailed instructions

Other than preloaded software what differences are there between the two? Any T-Mobile features I would be missing if I got the unlocked version?
I want to know this as well. Does the unlocked version support LTE band 66?
There's no T-Mobile bloatware on unlocked version. You can use Samsung's native Name ID and call blocking instead of paying T-Mobile $3.99/mo or whatever it is. There's very limited RCS support, almost none (should be fixed by end of 2017 when T-Mobile rolls out universal profile).
Otherwise, hardware and radios are identical. I heard you can flash T-Mobile firmware without any bad side-effects, to get all features/bloat.

I have the unlocked Note8 and T-Mobile is my carrier. Band 66 is supported. It also supports VoLTE and WiFi Calling, like the S8/S8+. The only thing that I've noticed missing is RCS/advanced messaging.

Went ahead and got the T-Mobile version, but thx!
Also, carrier models are generally more fined tuned by its carrier, resulting in better reception, connectivity, less battery consumption, and data speeds.
I would like to see someone attempted to flash the TMO CSC/CP over the unlocked firmware. have best of both worlds meaning no carrier bloat with video calling ETC
Ran a few speed tests one after another, between the Tmobile Note 8, and Unlocked Note 8. The unlocked seemed to do better then the T-Mobile branded one. It's seem to prioritize which band to use as primary better. For example Unlocked got 61mb down, and Tmobile got 16mb I guess just sitting on band 12. Last test I did, the Tmobile one did do better at 61mb, Unlocked at 56mb.
I'll be in a long drive heading to Hershey, PA and will have access to both again.

Ok doesn't seem like I will miss much by using the T-Mobile edition.
Also what is RCS?

ok so a couple of question before i placed my order.
1. Both the t-mobile version and the unlocked version are snapdragon chipset?
2. On the unlocked N8 you can flash the t-mobile Rom with no issue also without tripping knox / voiding warranty.

1.both are snapdragon chips
2. You can flash/Odin the tmobile rom without issue. And you can also flash/odin the unlocked version if you want to go back. No issues. I've done it a number of times the past few days. And no it won't trip knox or void warranty. You should also flash back to the original rom if you plan on doing a warranty replacement to be safe

Wow really? I was, contemplating between unlocked as well. But since it wasn't available in orchid grey I decided to go for the tmobile variant. But I don't mind getting black to trade for better download / reception.

Question for those with the unlocked SM-N950U Snapdragon version on the unlocked no carrier bloat firmware. Does it have the "Mobile Data" toggle when you pull down the notifications?
Does anyone have a guide to flashing the unlocked firmware/software on the T-Mobile version?

I had a T-mobile Galaxy S8+ and, 4 months ago, switched to Factory Unlocked Galaxy Note 8. What I have noticed is that GN8 has weaker signal... I rarely get 5 bars unless I am in the heart of Phoenix or Scottsdale, or Chandler, etc. I live in a rural Arizona City (Maricopa City)... and I rarely pull more than 2 bars out here... My wife has one of the big ZTE phones and her's gets 4 bars in our house.. you know why? Because it uses the T-mobile extended antennae that T-mobile sent me, a year ago, when I had my S8+. Obviously, my GN8 is not connecting to this antennae... That is why I barely get 2 bars, and she gets 4-5... sucks and i have to figure out a way around this issue.

Why don't you use wifi calling at home?
I have an ATT phone inbound that is unlocked by ATT however the owner says he tried his Verizon sim and it did not. work.
Can I flash unlocked stock firmware and have it work with Verizon sim or are they two different models with different internals.
If it will work can someone point me in the direction of the firmware that will work Please.
In the title, you say note 9, this forum is for note 8, I think it will more useful for you to look over there

Let me tell you, you've come to the right place. As you can tell in the subforum title, this is clearly the Note 9 forum. You've done well to come ask your question here.
More seriously, if I'm not mistaken, from what I've read around these parts of town, flashing the unlocked firmware should allow you to use a different carrier SIM. It's my understanding that most carriers use the same model, safe for maybe one, but I can't recall which one that is, now, since I'm not American and I don't really pay attention to those things.
I believe the Note 9 models will work the same as the Note 8 and previous models, in that regard. You can't really lose or break anything by flashing the unlocked firmware. Either it'll work with Verizon or it won't. Might as well give it a try.
It will not work 2 different kind of cell service. Tmoblie and ATT can work together and Sprint and Verizon can work together. One is CDMA and one is GSM
