I tried to start the process of unlocking my TMOBILE S6 today - first thing I discovered is that I need to get a new ATT NANO SIM Card - the Note 4 I am using has a Micro SIM - and the S6 uses the smaller NANO SIM CARD.
When I chatted with one of the online "unlock" web sites - they said they are not able to unlock the S6 EDGE because it does not give the user a prompt to enter an unlock code after inserting the ATT Sim Card.
he did not know if this would happen (or not happen) on the regular S6.
I am going to get a nano SD card from ATT and try it today - but after what I heard happened on the S6 Edge - It is not promising - it looks like TMOBILE is trying to close the door on people buying their phones and then immediately using them on ATT or some other provider.
If anyone has any experience they can share it would be helpful - I am going to see what happens later today after I get a new NANO Sim Card from ATT.
Updating my original post -
I have learned (thru attempting to use an ATT NANO SD CARD - that the only way to unlock the TMOBILE N920T at this time is by using a special AP available from TMOBILE - and then it will only work when TMOBILE has authorized it.
Cellunlockers or any of the other web sites that offer codes to unlock your phone will not work as you never are given a chance to enter an UNLOCK CODE.
I don't know if there are any other options - maybe secret samsung codes - or a special app by one of our illustrious developers - but for the time being, if you have purchased a TMOBILE S6 (like I have) and want to use it on ATT - it is not possible.
I would love to hear from any one who has an idea on what can be done about this (if anything) short of getting TMOBILE to give you an Unlock Code.
(I beleive the current policy at TMOBILE is that they won't give an unlock code until after 3 months of service. I might be wrong on that - but I beleive that is the situation.)
Any suggestions
What if i have been using T-Mobile for a few years now and decide to buy the phone full price. Wouldnt that also unlock the phone? My wife uses T-Mobile on her iPhone 5S and i wanted to buy a S6 Edge and pop her sim card in it, wait a few minutes and request the unlock. Would that work?

You might be able to do that - best to call Customer Service at TMO

T-Mobile has no idea how to unlock it and they claim that they won't until after the phone officially launches (April 10th). I have been on the phone with them for hours over this.
I'm officially 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 so I will be cancelling my service so that I don't have to pay for anything except for the phone itself. Good luck!
Wow! Lucky!
I tried 10 times with an AT&T sim but no luck.

I don't know if this will work for me but I will try when I get home - Just wanted to confirm - before hitting unlock app - did you install the att SIM card first? Then hit unlock ?

Since it's associated with your account u gotta have YOUR SIM card in there in order for the app to know if you are even eligible or not. So, u are correct, u have to unlock it with a T-Mobile SIM card than after it reboots (if successful) then u can put a non T-Mobile sim in.
My question is.. S
Did your phone say unlocked before or after you put in the Att sim card. Your first post wasn't clear. Also are you rooted or no?

What he is explaining is that he had his T-Mobile SIM card in the phone, he then opened the T-Mobile unlock app and tried to unlock the phone. And it told him no. So he tried a few more times, and finally it allowed him to unlock the phone. Then AFTER the phone was unlocked he put his AT&T SIM in and it worked.
The reason behind this is for the T-Mobile unlock app to work it has to check your account to verify that you are eligible for the unlock to occur. The phone will not unlock with any SIM that is not a T-Mobile SIM because it will not be able to verify if it is or is not eligible. And since there is no chance to enter an unlock code there is no need to put your AT&T SIM in the phone until after it is already unlocked. Basically they changed everything.
To be eligible for the unlock from T-Mobile, you must have an account in good standing at least 40 days old, and the device must be paid in full. So my suggestion would be to find a friend or family member that has had T-Mobile for a while and swap their SIM into your phone and do the unlock request, afterwards swap out your AT&T SIM and you should be good to go.
Thanks for the clarity that was lacking in the original post. Unfortunately I don't know anyone who has tmobile. Oh well... Waiting ain't so bad...
Unlock code
I bought an unlock code, as everyone stated the unlock code screen doesn't come up with an ATT sim installed but if you turn the phone on with no SIM in it and the. Go to the phone screen, type #7465625*638*# it will take you to the unlock code screen. I was able to get an unlock successful but when I restart the phone with my ATT sim it still says insert valid sim. Very weird and very frustrating. Have a friend that is prepaid. Trying that tomorrow

I tried too using AT&T sim card but a no go. I did get a successful unlock after entering unlock code but phone still locked.
I got lucky, had a chat with TMOBILE rep and they approved for the unlocK. I only opened the account a few days back. She did say it may take up to 14 days because the unlock cod or the device isn't available in the database yet

What did you tell them to give you the unlock code/did they tell you how to unlock it?

To unlock a prepaid phone, T-Mobile requires that you put at least $100 in your prepaid account if the account is newer than 1 year old. My question is, have you deposited over $100 in your account, or did you just recently open up the $30 line and you got lucky? Trying to replicate with my $30 plan I just bought

You are correct, but that is only one of their stipulations... You have to be activated for at least 40 continuous days for the phone you are trying to unlock AND your account must have had at least $100 of funds that have been put on it with the number assigned to the phone you are unlocking. With me, none of those requirements were met and my unlock still went through so I don't really know what the hell happened but it was def not policy. See, I have had the same prepaid number with the same $30 plan for over a year but I have not maintained continuous service. I jump from carrier to carrier so as long as I don't let my number get deactivated then I can keep going back to that plan but if I don't fund my account for over 90 days then my prepaid number gets recycled and I have to get a new sim card to get back on the plan I had. It may seem weird but I have been doing this 4 awhile now so I have caught on to the way T-Mobile works. I just put $30 on my account so that I could upgrade to the S6 but then I was told NO and that I had to wait til they were available at stores and that did not fly with me so I activated a postpaid account in order to get the S6 but I never put the new accounts sim card in my S6, I just immediately put the prepaid sim card from my old account in there and that's the way I got it unlocked. It's confusing but I'm trying to give you the best details I can so everyone knows EXACTLY what I did. Hope that helps...
Just bought a T-Mobile s6 today and it was unlocked when I purchased it, the guy I bought it from has been with T-Mobile for 5 years and he unlocked it right away when he got the phone. All you really need to do is find someone that has had a T-Mobile account for the said time and pop the sim in ur phone and get it unlocked. Working like a champ on ATT network.

So what is a prepaid sim? im relatively new to sim cards
I just got a new active from Att and I am not able to receive the firmware update. I have tried for the last two days (24-hr limit on update request). Each time the phone comes back with your software is up to date. I am on AOE9.
******I have an inportant information.******
I have a friend in Vietnam, I and him got an S6A.
I bought an S6A in Bestbuy, paid off.
He bought and S6A in ATT shop, paid off too.
But
I can get the unlock code after 2 days request in ATT webs => The staff in bestbuy told me, I can get the code if I buy ATT device in best buy for Free.
He tried like me, but the system said no => I asked 3 customers service in ATT website before, all of them said I have to contract an ATT SIM for 2 months (minimum $45/month for SIM card) and I could get unlock code after that for "free" after paid at least $90 for them.
the Important thing is :
My S6A (bestbuy) Cannot get OTA update (unlock or non-unlock) if I dont have ATT SIM.
His S6A (ATT shop) Can get OTA update (unlock or non-unclock) without ATT SIM card and another carrier in used. (he can get OTA for OF3 and the newest OF4).
*Yesterday,he bought an unlock code in a Vietnam mobile phone shop (~ $27) and It was unlocked, now he can use the vietnam's carrier.
I will show you the screenshot of his phone after I go home.
Sorry about my English
I really need to find out if I can salvage this phone I purchased from an aquaintance. A few days after purchasing this phone I then purchased a Family Plan Sim Card from Walmart. I then went to install it and the comment thay my phone flashed back at me was locked network on this phone and that the sim was the incorrect one. So I called ATT and was told to call back and see about a unlock code. I wanna know asap if possible if Im wasting my time to use this phone or if I can switch sims how please how!!?

They have a website to request unlock codes.

That is how I unlocked my phone after it was out of contract with them.
I'm heading to Europe in a month and plan on using a European sim as I don't want to deal with Sprints free slow internet and $25 a week is more than I want to spend. Sprint is telling me my phone is unlocked (and I was under that impression years ago) but I want to be absolutely sure before I leave due to issues I've heard people have with Sprint phones. When I do the UICC unlock (with the Sprint sim still in), the phone tells me it can only be used with Sprint and to contact them. I called Sprint and they told me it is saying that because the Sprint sim is in the phone and the phone will work when another sim is added. I want to test my phone with my friend's at&t sim card. I really don't know squat about sim cards considering I've been a Sprint user my entire life. Therefore, I'm wondering:
1. Can I just turn off my phone, put the at&t sim in, reboot, and see if things work to test that the phone is truly unlocked?
2. After I'm done testing, can I put the at&t sim back in my friend's phone, and my Sprint sim back in mine, and have things go back to normal, or will this somehow screw things up with his phone or mine?
