There is the Korean model, which you can find at 28mobile.com (not an endorsement), but it only supports the 700mhz band. The "international model would have all the wrong LTE bands for us. It's designed for Europe.

At least, that's how it has always been in the past.
[T-Mobile Samsung Galaxy S6] jackal2001:
The thing that sucks as these phone are only going to last 2 years with no option to remove the battery. Anyway post back and let me know what happens when you get your phone.
[T-Mobile Samsung Galaxy S6] jackal2001:
I wonder if T-Mobile got their pp slapped. Website only show preorder now.
[T-Mobile Samsung Galaxy S6] djkinetic:
If I end up picking up a Tmobile S6, i think I'll wait two weeks and get one off of Swappa from someone, undoubtedly there will be some ppl that dont like it or will have buyers remorse lol...to answer the question the S6 for TMO will work on ATT LTE, my Tmo s5 and g3 all work on ATT LTE.
[T-Mobile Samsung Galaxy S6] showstopper03:
Those of you who ordered on tmobile to use on ATT. How did you get around having to add a plan with the purchase? Did you go into the store? on their site i can not see a way to order the phone at full price without a plan of some sort.

Thanks
[T-Mobile Samsung Galaxy S6] pkulak:
You just say you have lousy credit and they'll make you pay for a sim kit and a $50 deposit. That deposit may or may not be refundable, and the phone may or may not need to be activated for 40 days before they will unlock it. Too much of a PITA for me. I just ordered an AT&T one on Amazon.
[T-Mobile Samsung Galaxy S6] greyhulk:
I thought the same thing when I ordered my AT&T Note 4 from Amazon last year. Currently, it's sitting a drawer collecting dust because I can't root it and it's useless to me without. This year, I bit the bullet and bought the T-Mobile version of the GS6. It's worth the extra $50 and hassle to me to have an unlocked bootloader and be able to root. If the Note 4 is any indication, it will be a long time, if ever, before you can root the GS6.

T-Mobile also does a lot less damage to the phone. They don't remove features (like Download Booster) or add extra logos (though AT&T's is much less obnoxious than Verizon's).

I requested a SIM unlock. The rep told me that since I bought it outright she didn't see why they should deny me, but it would take 24-48 hours. She said they could deny me though, because I haven't had service for 40 days. I suppose I could always unlock it through a 3rd party site and just pay an extra $20. Still worth it to me to have an unlocked bootloader.
[T-Mobile Samsung Galaxy S6] greyhulk:
Update on my Sim unlock: Initially, I was denied (after a 1 day delay while they "evaluated" my request). I called up today, talked to a couple of very nice reps and explained that I travel internationally and need this for work. They have escalated my case and are evaluating it again, though their system isn't registering my phone (because it's too new). I'm supposed to hear back by tomorrow. They are talking about giving me a temp unlock (30 days) until 40 days have passed, then a perm unlock. I told them I'd rather it was permanent from the beginning. We'll see what they say.

I could also just use a third party sim unlock site. I just wanted to see how hard this would be. It's a hassle, but still worth it for a phone that can be rooted and an unlocked bootloader. No more AT&T Samsung phones for me.
[T-Mobile Samsung Galaxy S6] jackal2001:
You are already paying $700 for the phone what's another $20 to get it unlocked
[T-Mobile Samsung Galaxy S6] greyhulk:
Actually, closer to $900 (64gb + tax + deposit). It's not about the money. I just want to see if T-Mobile will do it. And I'm not sure i fully trust those unlock sites. I've never used one.
[T-Mobile Samsung Galaxy S6] dligon:
I was hoping to buy a S6 from verizon since they're supposed to be around $70 cheaper and use it on AT&t just buy the phone full price anyone know if you could and what you may or may not lose doing that.
[T-Mobile Samsung Galaxy S6] pkulak:
Yeah, I hear you for sure. I'm not going to root, though. I'm actually pretty excited for Samsung Pay, so I'd like to make sure I don't blow any of that up. If AT&T disables Qi, or anything crazy like that, it's going right back though.
[T-Mobile Samsung Galaxy S6] greyhulk:
I was initially concerned about Samsung Pay. And it's things like that that make me want to avoid Samsung. You shouldn't be punished for wanting full access to your phone. But, even if they block it, I'll just use Google Wallet. I use it now and it works really well. I don't see Samsung Pay being all that revolutionary. And Wallet will be accepted anywhere that Apple Pay is, so it's still pretty relevant.

---------- Post added at 08:00 PM ---------- Previous post was at 07:59 PM ----------

Well, you'll get an obnoxious logo, some extra bloatware, probably a few services disabled (like themes and download booster) and you'll also get a locked bootloader. The Verizon version is the LAST one I'd buy. If I could live without root, I'd buy the AT&T model.
[T-Mobile Samsung Galaxy S6] djkinetic:
apparently according to android central the gs 6 comes with lookout and clean master bloat, clean master cant be removed as its tied to the frameworks/system services...my response to this is ewww... as such unlocked bl is the only way i'd get a gs6
[T-Mobile Samsung Galaxy S6] is350:
Correct me if I'm wrong, but doesn't T-Mobile use Band 12 for LTE and AT&T use Band 17? So then LTE wouldn't work on AT&T?

Edit: Also seems to use 29 and 30 which Tmobile doesn't have. So yeah just want to double check if the Tmobile S6 is fully compatible with AT&T LTE.
[T-Mobile Samsung Galaxy S6] greyhulk:
You're wrong. It supports all AT&T bands. Band 12 isn't even listed on T-Mobile's site and it still supports it (according to T-Mobile reps). But it has full support for Band 4 and 17, which are the ones you need for AT&T.
[T-Mobile Samsung Galaxy S6] jackal2001:
I might just get the att gs6 and give up on custom ROMs. I'm hearing that the devs don't like coding for these chips anyway as they cause more problems in the end.
[T-Mobile Samsung Galaxy S6] verks:
29 and 30 are missing from the T-Mobile model. ATT will push those out later this year to improve bandwidth. Otherwise you won't even notice.
[T-Mobile Samsung Galaxy S6] mocsab:
unfortunately, It appears that the only way to unlock the TMO S6 is thru TMobile - I tried today to use a NANO SIm Card from ATT - normally a field would open asking for an unlock code - then you could buy the code and unlock

BUT

Instead, you see a message saying you have to use an APP from TMOBILE and if your phone is authorized to be unlocked, it will work. For now, that appears to be the only way - maybe someone will figure out an alternative - but you won't be able to buy an unlock code from those web sites - because there is no place to enter the code.

I hope someone proves me wrong - or figures out another way to do it - I am not giving up yet - but only time will tell.
[T-Mobile Samsung Galaxy S6] greyhulk:
That's alarming, if true. There has to be a way around that, like a dialer code. I wonder what would happen if you disabled the T-Mobile unlock app and them tried it. Sim unlock should be universal.

---------- Post added at 03:48 AM ---------- Previous post was at 03:47 AM ----------

Dude, 29 and 30 are missing from most modern phones. I doubt we'll see heavy adoption of those for some time.
[T-Mobile Samsung Galaxy S6] mocsab:
- the message you see when you put an ATT Nano SIM Card in is that :"you need to insert a valid SIM" - then another mnessage says you need to use the Unlock AP from TMOBILE and if authorized, it will unlock the phone. I am not sure if what happens if you disable it - For now, I think either a Dialer COde or some special mod created by someone like Chainfire is going to be the only way short of getting TMOBILE to unlock it. Had I known this, I woluld have waited on buying the S6 - it was not like this on any other phone I have done this with (Note 3, S5, Note 4)

Fingers crossed that someone can figure this out...I know it is way over my head...
[T-Mobile Samsung Galaxy S6] ethanscooter:
I found an unlock code for the S6 edge but it doesn't have that much views I think it's kinda shady but it doesn't hurt to take a look at it though. :)

I AM NOT RESPONSIBLE IF THEY SCAM YOU I AM JUST GIVING THIS TO YOU FROM A VIDEO I FOUND

[T-Mobile Samsung Galaxy S6] greyhulk:
As an update:

Still waiting for T-Mobile to contact me about my SIM unlock. They said they couldn't see the phone in their system because there wasn't enough "use". So, I made some calls and sent some SMS and they're supposed to contact me today to follow up. It sound like they may only grant a 30 day temp unlock for now, but then I'll be eligible for the perm unlock 10 days later.

I will report back when I have received my temp/perm unlock. I was going to try one of the third party sim unlock sites, but mocsab has me a little worried about going that route now.
[T-Mobile Samsung Galaxy S6] jackal2001:
I was going to get the S6 but I think I'm just going to wait for the S6 active. If I don't like the active, I'll just decide between all the phones as there will be a ton of info by then.
[T-Mobile Samsung Galaxy S6] greyhulk:
Update:

T-Mobile has informed me that they will not have SIM unlock steps on file until after the official release date of the phone (April 10th?). So, apparently, getting it early is not always a good thing. Will report back after then as to whether or not it has been unlocked.
[T-Mobile Samsung Galaxy S6] mocsab:
the Cellunlocker site that I contacted said that they can't unlock it because of the way TMOBILE Locked the sim card. YOu have to be authorized to unlock by TMOBILE before it can be unlocked - So it looks like we have to wait the 40 days - not sure if TMobile will allow any other option - but you can call customer support and find out if you are willing - I was hoping that someone would find a secret samsung code to unlock sim - it has worked before on other phones - so did flashing regional unlock ap from CHainfire on the s5 - but I am not sure (i actually doubt) if that will work for us. It did not work on the NOte 4. Fingers crossed someone finds a way....
[T-Mobile Samsung Galaxy S6] wahoofan5:
Did you use Cellunlocker.net? I submitted my IMEI to them, just waiting for an unlock code. If you insert your AT&T sim, go into the dialer and type in #7465625*638*#, it brings up an option for Network Unlock Code. Will report back when I get my code.
[T-Mobile Samsung Galaxy S6] mocsab:
That is Awesome News - or it could be - I hope you will report back your results IMMEDIATELY - I'll be on it like a pig on mud - by the way, where did you get that dialer code?

By the way I bought my s6 outright paid in full - did you?
[T-Mobile Samsung Galaxy S6] wahoofan5:
I didn't buy it outright, but if I can get it unlocked through Cellunlocker, I'll pay it off immediately. I submitted my IMEI to them last night, and they say they have a 1-2 business day turnaround. Hopefully someone with an unlock code in hand can try for us. I'll keep everyone posted when I get my code. I did some deep googling about network unlocking older Samsung phones, found that code, and voila, it brought up a network unlock screen on my S6.
[T-Mobile Samsung Galaxy S6] greyhulk:
I bought a code from Unlockunit.come, but haven't received it yet. I was wondering how I'd input the code and figured I'd get screwed. I thought there had to be a dialer code override, though. This is awesome, if it works. I look forward to your report and I will report back as well when/if I get mine.
[T-Mobile Samsung Galaxy S6] mocsab:
First don't freak out about anything I say - I think I know more about stuff than I really do - :) Someone else posted a thing saying there was a way to open the field to add an unlock code on their phone - they signed up with Cellunlocker.net and are now waiting to get their unlock code to see if it works. The code was only 19.99 so I signed up too - and am waiting to get an unlock code - it could be 1-2 days to find out - so I am playing the waiting game until someone else finds a way or I get an unlock code that works. I will report back what happens -
[T-Mobile Samsung Galaxy S6] greyhulk:
So, T-Mobile sent me an unlock code. The instructions were generic (nothing about the unlock app or the dialer code). I used the dialer code to call up the unlock screen and the code they gave me doesn't work! Ugh.
[T-Mobile Samsung Galaxy S6] wahoofan5:
I didn't know they just gave out unlock codes if you got permission. First off, how did you get them to give you one? Second, call T-Mobile and ask them how you go about entering the code they gave you. It might clarify things for the rest of us
[T-Mobile Samsung Galaxy S6] velgador0:
I bought a code from cellunlocker and tried entering it with the dialer code, it didn't work.
[T-Mobile Samsung Galaxy S6] greyhulk:
I was on the phone with them for quite a while. It seems the unlock code was sent by mistake. They are standing by the "wait until launch" answer from before. Apparently, they must have a device in house to test the unlock steps before they can send out the proper method. This has all been a lot more trouble than it should have been. I'm still waiting on my third party unlock code. Who knows? Maybe that one will actually work.

---------- Post added at 11:20 PM ---------- Previous post was at 11:07 PM ----------

Same here with Unlockunit.com. Not looking forward to battling with them for the refund. Interesting fact: They sent me the same unlock code that T-Mobile sent me. So, I'm not sure what's going on, but this phone is insanely hard to unlock. Maybe it's because it's not officially launched yet? Maybe the codes will work after the 10th?
[T-Mobile Samsung Galaxy S6] velgador0:
I doubt that the codes will suddenly work on the 10th, maybe they noticed how many Note 4s were bought and immediately had canceled contracts from all of the people on ATT who wanted root.
[T-Mobile Samsung Galaxy S6] wahoofan5:
Unfortunately, I am getting "Network Unlock Unsuccessful" when I type in the code with my AT&T sim inserted. I find it hard to believe that it is impossible to unlock this phone
[T-Mobile Samsung Galaxy S6] mocsab:
I spoke with the people at Cellunlocker today and they said that the traditional unlock method will not work with the S6 - they said they would have a solution with 7 to 10 days and seemed very confident that they would be able to create a way to unlock this phone. (the guy I talked to said that this happens with phones very occassionally - but that they normally are able to get a work around that works.

Not the best news but I am going to try to feel positive about this and hope they are able to come up with a solution - if not, then I just have to wait the normal 40 days to unlock - oh well -
[T-Mobile Samsung Galaxy S6] greyhulk:
I'm working on getting a refund from unlockunit now. They require video proof. It figures that the one time I do this: buy a phone on another carrier with the intention of unlocking it, this would be the most difficult phone ever to sim unlock. Oh the things I do for an unlocked bootloader.
[T-Mobile Samsung Galaxy S6] mocsab:
I paid for Cellunlocker and I am going to let them continue working on a fix for this - my fee was only 19.99 and they seemed confident they would have a fix in 7-10 days. If they don't I can get my money back then - but I feel pretty good that they will find a way. (I may be overly optimistic - but whaT the heck - its only 20 bucks)
[T-Mobile Samsung Galaxy S6] is350:
Does anyone know if the 40 day policy still applies for current Tmobile customers as well? I have a friend who has Tmobile. I was hoping to use his account to buy the S6 at full price and then be able to unlock it right away for AT&T use.
[T-Mobile Samsung Galaxy S6] serialtoon:
Im thinking of doing the same. Although my wife is the one that uses T-Mobile. She has been for over 2 years.
[T-Mobile Samsung Galaxy S6] greyhulk:
Word of caution: Unlock Unit did all kinds of troubleshooting with me. It involved entering an "unfreeze" code first, wiping the device (screw that), and inputting a dialer code to get to a special menu to find "network lock" and change some settings. None of the steps worked. So, if Cellunlocker comes back to you with any of that, don't get your hopes up.

They insisted on a video proving it didn't work. Luckily, I'm rooted, so I just used a screen recorder. I can't believe that it's so hard to sim unlock this phone. I really wanted it and I didn't want to wait and this is what I get. Good luck.

On a side note: T-Mobile's service is actually pretty good and the unlimited data package is a steel. If I wasn't stuck in a corporate plan with AT&T, this would totally be when I switched.
[T-Mobile Samsung Galaxy S6] stu5797:
Since you are rooted can't you just delete that t-mobile locking app and tour problems be solved?
[T-Mobile Samsung Galaxy S6] greyhulk:
I'm pretty sure that app isn't blocking it. I disabled it before attempting my unlock code once.

I wouldn't delete it. It may be the only way for T-Mobile to sim unlock the phone, since the raw codes aren't working.
[T-Mobile Samsung Galaxy S6] stu5797:
I just assumed you would always have titanium backup backup the unlock app if things went bad
[T-Mobile Samsung Galaxy S6] greyhulk:
Yeah, but there's literally no reason to delete the app. It's not the gatekeeper. It is just the way that T-Mobile has to unlock your phone remotely. It seems like a backend thing, like the phone isn't authorized to be unlocked yet, probably because it technically hasn't even been released. I guess we'll know for sure in a week or so.
[T-Mobile Samsung Galaxy S6] mocsab:
Cellunlocker.net said they would take 7-10 days - that implies they have done this before and know that it is not easy and requires some special programming or something on their side. It may also hav something to do with TMOBILE or Samsung not allowing accurate unlock codes to be developed until 10 days.

(TMOBILE told someone else who wanted a temoporary unlock that they could not help them until the S6 was actually available to every (April 10th)

SO - I am still optimistic that it will happen - IMHO it won't happen until until after April 10th. (I don't mind waiting)

Unfortunately for me - TMOBILE Service is way below par compared to ATT - LTE speeds don't begin to compare - and I can't even make a phone call inside my house. (I know, WIFI Calling - which I use - but there is something inherently wrong with having to use WIFI to make a phone call. It tells me that TMOBILE knows their service is substandard and to fix it, they come up with WIFI Calling so that people who have TMOBILE can make phone calls inside buildings. I exagerate a little but I bet there is some truth in that..
[T-Mobile Samsung Galaxy S6] greyhulk:
I'm the one they told that they wouldn't be able to unlock until after the 10th. I'll be interested to see what cellunlocker tells you. They may just be buying time until unlocking is actually available.
[T-Mobile Samsung Galaxy S6] mocsab:
You may be right - I paid 19 when I tried originally to get a code - they said it is going to take more time and a lot more work - ultimately that it will be more expensive too - but if I was willing to wait, they whould not charge me extra. After mine gets unlocked (power of positive thinking :) ) it will most likely cost more than the 19.99 I paid.
[T-Mobile Samsung Galaxy S6] shojus:
I'm UNLOCKED!!!

I can tell you that I have had my S6 for about 4 days and I put my prepaid sim card in it instead of the one it came with (had to create a postpaid account so that I could get this phone!). I tried to unlock with the app on the phone and it told me NO, I am not eligible to do that, but I just tried it a 3rd time about 30 mins ago and BOOM! I am permanently unlocked and can confirm that AT&T works great! :) The phone rebooted and it automatically froze the unlock app. LOL I un froze the app and sure enough, I am perm unlocked! Not bad for using the phone for less than a week and not calling T-Mobile even once to ask. Just wanted to give people a heads up in case u wanted to try this yourself with a pre-paid sim (if u have a prepaid account, of course). I love my $30 plan!
[T-Mobile Samsung Galaxy S6] greyhulk:
Not sure what's different with your situation, but I just tried again and was denied.
[T-Mobile Samsung Galaxy S6] guyd:
Do you have LTE on AT&T? Your screen shot shows HSPA. I would think that you should have it, since only one LTE band is different between the two devices.
[T-Mobile Samsung Galaxy S6] shojus:
It was not an active sim so I could not test that but it has the LTE bands so it WILL get AT&T LTE 4 sure just like all the other Samsung devices do... I just had a sim card to test that the phone would boot up and read the AT&T sim , which I showed. If I can get a friends card I will post a pic but I know it gets LTE so I'm not worried about that.

---------- Post added at 08:42 AM ---------- Previous post was at 08:36 AM ----------

I am rooted and froze some things but other than that I don't know what's different or if it has to do with anything I did to my phone. Trust me, I am bewildered too but I tried 3 times and was successful on my 3rd try. Keep in mind that T-Mobile does not recognize the phone change on your account for a couple of days so try after a few days of having the phone and are you on a prepaid account or postpaid? Just curious as I wanna see if this is able to be replicated somehow...
[T-Mobile Samsung Galaxy S6] greyhulk:
I'm on Post Paid because it was the only way I could order the phone online. I have tried everything from resetting data on the unlock app, perm and temp unlocks, to inputting the code T-Mobile sent to me manually using the dialer (and that code was later confirmed by Unlock Unit when they sent me the same one). My theory is that my phone is somehow not authorized on the back end to be unlocked.
[T-Mobile Samsung Galaxy S6] shojus:
Same here, I have a prepaid account but they would not let me pay for the phone outright and have it shipped unless I had a postpaid account so I signed up for service but never put the postpaid sim in my phone. I put the prepaid sim in my phone as soon as it was delivered and I am going to cancel my postpaid account today. I will say that they did unlock my Note 4 for me on my prepaid account but that was months ago so idk if that has anything to do with me having good luck or not but they DID make me wait 40 days when I first got my Note 4.
[T-Mobile Samsung Galaxy S6] greyhulk:
So, just to clarify, you unlocked it with your T-MOBILE prepaid sim? Because all the unlock instructions state that you're supposed to use a non-T-Mobile sim. I have tried my inactive and active AT&T sims and neither works.
[T-Mobile Samsung Galaxy S6] shojus:
Correct, I had my prepaid T-Mobile sim in the phone that I unlocked. And then it said that the unlock was successful and rebooted and it literally froze the unlock app on its own so I had to look for the app after I was done just to verify it was indeed unlocked. After that I put in an inactive AT&T SIM card and it read it perfectly! That was it! I thought it was gonna be a huge hassle but it literally took 3 tries and about 5 days with the phone.
[T-Mobile Samsung Galaxy S6] greyhulk:
I have had it tell me that the unlock was successful with my T-Mobile sim in, but as soon as I put my AT&T sim back in, it tells me that it's an invalid sim.
[T-Mobile Samsung Galaxy S6] shojus:
WOW! That is super strange! I'm gonna go to my friends in about 15 mins and try his ACTIVE AT&T SIM card in my phone and double check but I already restarted the phone several times and it connects to their network and gives me zero errors so I can only assume I'm good to go. Give me an hour and I will post my results with an activated sim card.
