Hey,
I just recently moved to the USA and I am trying to set up my Note 3 to work with AT&T but I'm not sure how to do that.
The phone I currently have is a Rogers Galaxy Note 3 N900W8 (Already knox 0x1), and I'm curious what I need to do to make it work with my AT&T sim card.
I was hoping to stick to ViSiOn-X but from what I can see that is not available for AT&T, so I'll probably just stick with the stock ROM, whichever that is.
Though, I do still have a phone plan in Canada and would like to switch between the sim cards so that I can check my voicemail if at all possible.
Is it possible to set up my phone to work with both Rogers Canada and AT&T USA? Or am I required to purchase a factory unlocked phone to do that?
If it is possible, how?

You need a factory unlock so you can switch carriers now as for the rom I'm not sure if the rom will work on AT&T, you should check the rom forum an see if other AT&T users used it an if don't already know the Model for AT&T is SM-N900A, also you could always try the rom once you get an sim unlock, an try it with that rom but if it don't work flash a rom that you kno will work

Ive got my phone unlocked now, but I think there may be some issues with the ROM. When I first unlocked it I was getting the 4G connection to AT&T. Now I just have the regular phone connection, no 4G. Data is on.
Hello
I have unlocked my s6 by using the metro pcs firmware upgrade method .
I have reflashed the t mobile deoxed version rom .
All was working fine until few hours ago when my phone stopped receiving network .
Reboot didnt work too until i switched on wifi back on .
Is it something to really worry about ?
One more queery: once i unlocked my phone does it mean its permanently unlocked to any network because right now im residing in asia .

I think both questions have the same answer, you can't use any other firmware other than metro pcs. I remember seeing that in a different thread. If you paid it off free and clear call tmobile and they should permanently unlock it for free. I think all you need is your imei or serial number.
So can i reflash the metro pcs firmware and still have the device unlocked ?
I have purchased the unlock code off one of the leading sites on web.
I called T-mobile and pestered the hell out of them and they in return pestered the hell out me, in the end I have an unlocked phone with no flashing this and that.

I can't give you a answer but why not call tmobile like ipaq_101 did? That way you don't need to care what firmware or rom your on, it will be universally unlocked. If long distance calling is a issue you can use the online help, just make sure the first rep you talk to knows you won't stop bothering them until it's unlocked.
Is it not possible to install a ROM and then, say, flash a MetroPCS modem or something? For the record, I'm in the same predicament; I'd like to flash a ROM, but am running stock MetroPCS firmware that allowed me to use an unlock code.

You can flash any compatible ROM. I Odin flashed the MetroPCS firmware only so that I could permanently unlock the SIM. (I found that the T-Mobile Device Unlock is buggy and not exactly permanent). Then I flashed the international "F" version of Alliance ROM along with UniKernel. Been working great!
As long as you don't ever flash a T-Mobile radio, you'll stay unlocked!
Does Permanent unlock mean permanent? Or is it something you can lose with a firmware update, factory reset, or user modification?
How does the device unlock? Is it unlocked by hardware like a knox trip? Is it from the carrier? Could it ever be re-locked?
Basically I bought my S6 from T-Mobile with the full intention of cancelling the service once I fully payed it off. $860 later, I made my final payment a week ago. I put in an ATT sim card, tried unlocking, nothing happened. Put my T-mo sim back in, did unlocking just to try it again, and it says my device is permanently unlocked.
I just want to know how permanent is permanent, and is it safe to cancel my service with T-Mo, and could the phone ever be re-locked by means of factory reset or by any change in the software?
Also my T-mo account balance is -$60, I don't fully know what that means, but it appears that they owe me $60. If I cancel, is a negative amount refunded?
It's supposed to be permanent. But T-Mo's custom device unlock is bugged. I permanently unlocked mine a few days ago and switched back to AT&T. Last night I started getting an invalid sim inserted message with my AT&T sim in it! So much for permanent unlock!!!
All I could think of doing to make sure it's permanent this time around is to Odin back to the stock MetroPCS rom so I could use their radio and unlock it the old fashioned way. Works fine with AT&T now. I just have to stick with the MetroPCS radio, or it will become locked again!

I've been away from android for a short time and now back on T-Mobile S6. I bought it outright from T-Mobile and haven't even had it three days yet but service is terrible. Is there a guide for exactly how to use the PCS firmware and then get root and twrp? How and where did you get the unlock code also? You said I need to stay on PCS? What if I flashed a T-Mobile custom rom off xda development site? Thanks, I'm just a little rusty and don't want to mess up my new phone. LOL.

There is a guide somewhere. I read it a couple of weeks back, so I knew what to do to Odin flash the Metro rom and use the regular sim unlock method. You can flash any compatible rom with your device. You just can't flash the T-Mobile radio, or you'll loose the SIM Unlock! The radio firmware is never part of a custom rom, so no need to worry there.
I bought the unlock code from androidsimunlock.com and told them it was a MetroPCS Galaxy S6. Worked perfectly.
Thanks. I'll do some more searching.
So the unlock is in software only?
Sorry, i'm not sure how the OTA's work on the Nexus devices, so I have to ask (and haven't found the right discussions which talk about this)...
I have an ATT branded Nexus 6 which has been bootloader unlocked, OEM partition wiped, and flashed with the "for T-Mobile" LYZ28J image. I am using a Verizon SIM in it.
Since there are posts of T-Mobile pushing LYZ28K I was wondering, will get get this OTA? if so when (i.e. does it it matter than I have a Verizon SIM in there when it comes to OTA's? Or do I manually need to load it?
It doesnt matter that it has a vzw sim in it. If youre stock, you may get it, and you can apply it - but when? Nobody can tell you that, you'll get it when you get it.
If you are waiting for Tmo specific firmware on VZW service, that isn't going to happen - you'll never get that since...well...you dont have TMo service...
Lol what's the reason behind an AT&T branded phone with T-Mobile Rom and Verizon sim? Personally I would just manually do it, like the dude with the hilarious name above me said you may get it you may not. If you want it just go manual.
^^ exactly.
Thats what I've always done - if i want it (and since I'm never stock) I have to manually flash the firmware, make my own no-enforced encryption boot.img (kudos to the kitchen) flash that, and start all over.
Thats how it is, I'm used to it. OTA are too slow, IMO, anyway.
EDIT:
I use this name universally online - any forum you see it, XBL, GitHub, reddit... it's me. lol

Long story short... its a work supplied device. I asked for unlocked/unbranded and got the ATT branded (but sim unlocked). My primary work line is Verizon, backup/test line is T-MO.
We have others that will likely be in the same boat (ATT branded, sim unlocked, but using other provider).. who are not techie. So rather than flashing or side loading the OTA (which I easily could), I'm waiting to see what happens.
I'm more curious *IF* I should get the update in this state. and if the mix of rom vs sim might cause any delays/issues.
Bottom Line. Verizon and ATT don't usually OTA for 3 months after update release. Once the factory image for Sprint, USC, International drops you can fastboot flash that They gonna use the same and it will work. T-Mobile and FI work better with their drop just because of WiFi calling.
I'd say that because you're using VZW service, it makes absolutely no difference what branding the phone has and doesn't matter what carrier it was purchased for.
If it uses VZW service, you'll only get OTAs that are for that service. You won't get Tmo specific OTAs for a device being used on VZW - when the OTAs are pushed out they are done so by the service the device is registered as using. I don't think you would ever get said OTAs since the device wouldn't need them.

Thank you. And that is what I'm thinking, and why I'm asking... because I'd also seen talk about the SIM in the Nexus 6, or the carrier the phone is on, impacting some of the Nexus 6 updates in the past.
But I also remember my Sister-In-Law using an XT1053 on ATT, who did get XT1053 updates.. SO I wasn't completely sure how the nexus updates worked.
Yes. If leave the sim in will get the Verizon OK'd OTA. That has been up to 3 months after the image was posted. Either remove sim and try to force OTA from Google or manually flash the image. We end up always manually flashing due to having root.. 3-5 minutes tops.

That's not accurate.. On every other android phone it is accurate but not in the nexus 6.
Usually with a GSM phone, the update is pushed by the oem and your current build determined which update you got.. For example, my Three UK s3 would get the Three UK branded rom update. Even if I had an O2 UK sim in it.. If I then flashed a Vodafone UK rom, I would then get those updates.
With the nexus 6 though, this has changed.. For Verizon and T-mobile users, Google now uses the sim to identify which update to get.. They both were sent with an unbranded stock rom then later on, depending on the simcard, got either a t-mob or vzw update.
The problem is though, that each update will only install on a specified build.. So a vzw update will never install on a t-mob rom or vice versa, so it does matter if the build is one carrier and the sim is another as it will never get an update.
That's what I meant, I probably should have worded that differently.
I meant that even though it is using Verizon service you only get updates for Verizon service. If it's branded for X carrier that won't matter - the service its using is what you'll get updates for.
I apologize about that that was a poor choice of wording on my part.
And just an update.... tonight, I got prompted for a 28meg update. After the update I'm on LYZ28K.
So I guess to answer my own question...
Yes, an ATT Branded Nexus 6 flashed T-Mobile ROM with VZW SIM installed will get updated, and stay on the T-Mobile rom.
That is good.

Should get the Verizon/ATT (Generic ) rom if have Verizon sim. Hopefully you unlocked before taking update. If locked and it bootloops your only option is RTA.

Yup. I unlocked. Actually when I got it, I unlocked it, rooted, cleared the OEM partition (backed it up first), then flashed the T-Mobile rom.... and left it unlocked (but not rooted since I'm using for work)
Hi guys,
I need some clarification re: carrier unlocking and how it works. I recently purchased a carrier unlocked G920T, and I was going to start messing with custom roms/kernels and other goodies. My question is: Will the phone revert back to being locked if I do a factory reset or if I unlock the bootloader and flash custom roms?
I'm not a T-Mobile user, so I can't get another unlock code from them.
Thanks!!
The G920T has a carrier unlocked version, which is probably the one you have, not the T-Mobile one. Even if it is, usually a carrier unlocked device will remain unlocked forever unless it was unlocked using a different or hacky method, then there is a possibility that it will relock
Sent from my SM-G920T using Tapatalk
Yeahh go ahead, mess with it. when it is carrier unlocked, the software doesn't affect it, unless it is a hacky method like @serio22 said, but there isnt such hacky method for the GS6 so have fun.
If it is a G920T (the T means it's from T-Mobile), then carrier unlocking is not a guaranteed state. I paid T-Mobile the full price to get my GS6 and they "permanently" unlocked it. Then after a OTA software patch all of a sudden it locked itself again and I couldn't use my phone for 2 days while they tried to unlock it. T-Mobile's new device unlocking uses a new system which has the phone "phone home" to their servers to check if you're allowed to use it outside of their network. It happened again when I accepted the Android 5.1.1 OTA. So...beware of T-Mobile's not-very-permanent permanent carrier unlocking.
I am living in india..
My relatives brought me the t model ( i wanted f model instead of i sold in india for quicker updates but got t model...lol )
Anyways,
The moment i inserted my sim, it worked like a charm so its unlocked at the moment.
I dont know how they made payment their or how it was unlocked, but the way used must be legit coz its still stock at the moment without root / recovery etc. .
I read humo saying it can get locked again...
My main question, what are the odds of that happening?
Also since i live in india, i wont be able to contact t mobile via phone/walk in, are there ways i can get it unlocked again?
I dont have the bill too if it matters
i believe they have an app that unlock ur device since that is how i unlocked mine. if not u can try to contact customer service online since u r not in US.
With device unlock app , will i have to pay for unlock my s6 g920t or it'll unlock my device for free.
I have an unlocked s6 tmobile from usa, i heard the flashing stock rom will relock the device.
If the phone will relock then how can i unlock it again?
I'm not sure about flashing a stock ROM relocking the device. Mine re-locked when T-Mobile sent Android security patches. This week I did the Android 6.0 OTA update and it has remained unlocked.
Hey guys! i have a factory unlocked version of s6 tmobile, my question is if i can flash the tmobile MM firmware . My model says "country: cellular south" and the firmware country says us tmobile, so i dont know if i can flash without any problems, (Sorry for my english it sucks) thanks !

You can't downgrade your bootloader so you'd have to pay to unlock it unfortunately

Got it done remotely!
I have a Galaxy S6 (SM-G920T) from T-Mobile. It was locked. But it has an "Unlock" app installed by default. I used it and phone was instantly unlocked! Fast, easy and free!
I used to live in the US for a year and bought a g920T. Since i had the requirements i Unlocked and came back to my country but because of a problem, I had to install a stock firmware and now the unlock is gone.
So i'm wondering, if someone with a unlocked phone made firmware backup, remove the IMEI, and send it online would it work? I mean, right now it works just fine, so i can backup my IMEI and ID and just restore it if needed.
Please help
