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,

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

I bought a Verizon Galaxy S6 Edge few months ago. Now I moved to T-Mobile. I am using the phone right now without any issues.
There is still Verizon crap on it that I cannot uninstall. Is it possible to install stock or preferably, T-Mobile firmware on this device?
I'll just keep it short and sweet. Practically speaking, no.
Better explanation please
The phones are identical except the firmware. Why would it not work? I would like to do the same so I can access better reception and wifi calling. There's literally nothing different Hardware wise between the diff carrier versions other than what each carrier unlocks or blocks. Can someone give a more detailed reason why it won't work?
This is a great question.... I'd like to know the same, BUT, for me, Tmobile charges too much for single service here in Colorado.
What about just bypass frp?
As far as I'm aware I believe the Note 5, based on the Exynos7420 uses a different modem chip in each carrier. Originally I thought the S6 Edge was still a universal World Phone. But even rooted, some people have still had problems actually migrating from Verizon to T-Mobile.
I've had a tester somehow manage to install a TMobile modem on an AT&T Note5, but it messed up the Device Root Key. Which I do believe is the "hardware baked" signature used to decrypt firmware.

Look at the instructions posted here to remove bloatware. I believe if you substitute the correct counterpart firmware the process is still doable. There is also the De-Bloater v3.90 app that should work as well.

If I have a repair guy put an AT&T MoBo in my T-Mobile (N910T) phone (mine died), will I still have wifi calling, etc., after loading MM for T-Mobile?
I'm thinking no, but he asked if it would be OK.
Other downfalls? Would I even be able to Odin MM for TMO?

the motherboard is still ATT not Tmobile, I don't think the firmware will flash since the main board is not N910T, u will need to flash the N910A
I don't think it will work, but that is just me... I'm a computer tech...

I tend to agree. I didn't know if Wifi Calling is a part of the MoBo, or another chip elsewhere. I know that I could get the phone to work on the TMO network, but that alone is not good enough.
At any rate, I'll just tell him NO.
Thanks for the reply!
ATT still isn't rooted or bootloader unlocked. You'd be stuck on lollipop, since att still hasn't released marshmallow. I'm an ATT guy that put a Tmo motherboard in my phone so I could be unlocked, rooted, and flash roms...

As long as it's a 910t, it should be fine. I don't know about the t3 or the w, so do some reading. It's been awhile now, and I took a leap of faith before I did mine, so I can at least confirm the 910T motherboard will work.
Anyone know if the exynos version would work on verizon? I assume that that it would but the 1x and 3g would not. lol, i would be ok with that if i also go root and TWRP.
My follow up question is where could we order it? It would be nice to get it right from samsung, but i don't see that option.

i think this is the place to buy it. Since they will open it up and use one of their sims to make 5 minutes of calls before sending it to us, so it doesn't lock up once we get it.
Has anyone used 4g exclusively on verizon, what are the drawbacks?
I know where to buy it here in the US. I could actually buy it today. Just want to know if it will work on Verizon

I dont think you will be able to use it to make phone calls or msg because verizon use a CDMA network for this and the exynos version doesnt have this. Just my guess.
Samsung's soc never supports cdma (big Q owns the patents) so that's why the rest of the world who aren't on cdma gets the exynos versions

That's not true at all, my Galaxy Tab S2 is an Exynos and runs on Verizon LTE., and the galaxy S6 was an Exynos 7420 on Verizon.
Oh I stand corrected. I knew the tablets were supported but figured since you don't make calls from them, it wouldn't need cdma. In either case, unless it's made for Verizon, the exynos versions won't natively support Verizon.
The FCC filing shows it support the Verizon LTE bands, but no CDMA bands.
It would probably work for data but I am not sure if it would work for calls, unless they implement VOLTE on the international version for Verizon.
Guys it's best to wait for the North American unlocked version (Qualcomm chip) to become available in a couple of weeks or so.
It will definitely work on both Verizon and Sprint and their MVNOs.
I can see bhphotovideo taking preorders for it already, and the page is setup on bestbuy. This is the S8 version I'm gonna go for. Downside is it will cost you a little more, but it is worth it to me to know I can use it on all US carriers.
Edit: looks like bhphoto added the model numbers for their preorders as "SM-G950F" and "SM-G955F", which is the same as the European/global GSM version. So that is Exynos chipset powered, and it's a no go for CDMA guys.
The plus on this model is it gets the software updates more quickly than the US unlocked model. (This is still speculation based on Samsung not updating SM-G930U to Android 7 for months while the SM-G930F and the US carrier models already received their updates.)

unlocked as in unlocked BOOTLOADER? Or just for use on any carrier?

Unlocked as in "unlocked for all carriers" (or "sim free" is what Samsung UK calls their SM-G95*F versions). But I wouldn't be surprised if the bootloader is also unlocked.
My guess, even with the unlocked (unencrypted) bootloader, is once you flash a custom ROM/recovery it will still trip the Samsung Knox binary counter and void the warranty. This is just speculation based on Samsung's devices in the past. We have to wait until someone gets their hand on the US unlocked version.

Sim unlocked at best buy will be out may 9th priced at 725/825
i buy international versions all the time...
don't listen to all these people who just make things up but never used it.
supported bands according to this site just an example:
http://www.china-prices.com/phone/bands/7922/samsung-galaxy-s8-exynos
I have the exynos s7 i bought from B&H in US. on verizon CDMA won't connect, but if you are in a region with VOLTE and you don't travel within US, it should be fine.
all the international versions have much better support if you are on ATT/Tmobile where GSM is the "3g/crippled 4g" I left verizon for Tmobile just to get better support for Exynos.
now... i didn't check validity of the site above, but it gives u an idea. i just wanted to chime in.
Exynos has much better power management IMO. my wife's phone is S7 tmobile variant, and when i was using s7 Exynos, my battery life was BETTER AND i use the phone way more than her throughout the day.
going to, i actually bought s8 TMobile this time... just so i can use samsung pay... samsung pay will work if you modify the CSC and install spay/framework, but guess i'm getting old and getting lazy
exynos will likely get rooted FIRST, and the first root type will likely trip Knox, and without Knox, no samsung pay...
TLDR. Exynos will work on vzw but not all the bands. if you think it's too risky, don't get it.
2 upsides that actually matter IMO when it comes to Exynos versions.
1. less bloat, I say less, because Exynos versions come with all kinds of CSCs from all over the world. and depending on where it came from... you'll see it installing regional specific apps on your initial boot. 1 year i had a phone with Arab CSC and it installed bunch of apps made for Arabs... on another phone i had a UK CSC and it installed all kinds of UK news apps.
2. better battery
3. faster updates from sammobile

I read it I just think its a dumb GSM phone for people that have a dumb CDMA phone provider. LTE only is not a solution Verizon people simply need Verizon phones. Just like Sprint people need Sprint phones. Getting international GSM phones for use on CDMA service providers is stupid. Thats one reason CDMA is crap compared to GSM. Unlocked phones like some apple and moto and rare samsung are the best solution. Best Buy will have the unlocked snapdragon available in 2 weeks for $725/$825

You dont need regular calls? You are going LTE only and hoping you dont miss any calls? If you are using hangouts for calls and don't need cellular phone calls then go get one. Ebay, amazon, they have them for sale, forget warranty unless you want a huge hassle.

I understand everything. I was wondering who has done it in the past. Everyone in my company with the latest update from Verizon has seen their CDMA coverage disappear. Where they once had CDMA service, they now have none. Verizon seem to really be pushing the VoLTE. I've had phones where i have disabled all non 4g bands, because i didn't like it switching, and it actually worked better for me. The main reason i ask is because the international version has root and TWRP. Hopefully the US version will get root, but i don't think we'll every get an unlocked bootloader. The verizon version is already sim unlocked, so i'm not looking for more sim unlocked phones that don't have root.

Thanks for your help and concern. haha, i still don't want to be the first. I'm going to see what happens here before i get too serious about getting it. The risk in waiting is that the current unlocked bootloader method for the exynos may get patched. idk
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
