Thanks

EBay. They usually have them for around 20 bucks. I don't really trust some of the other third party sites unless someone directly refers me.

Saw this from /r/android on reddit.. People said that it would work, but needs to be on stock rom though: http://forum.xda-developers.com/showpost.php?p=34661189&postcount=1

Is your phone unlocked? Check to see

I got my UNlock code put in a at&t SIM..... put in code... then it said unlock successful...
But upon checking this unlock with this code.
*#7465625# it still says locked!!!
Will someone punch in this code that has there phone unlocked and see if it says network lock off.
Or if it still says locked!!!???
It's driving me crazy......

I purchased mine as unlocked but haven't had the chance to try another company's sim card on it to verify that.
I checked with the *#7465625# code and it looks exactly like yours.
I unlocked my sgs2 and tried that code and everything is OFF.

It looks like you are in different ROM. To unlock ur phone you need to be on stock ROM!
I did it on my s2. I was unable to use code on AOKP so i flash stock rom, unlock , rooted again and back to stock again.

I requested and received the unlock code from T-Mobile. I tested this by making a call using an AT&T sim card.
My screen is identical to the one above, including the typo. My phone is definitely unlocked!!!
Same thing, as all of you. I get the same pop up. I tried it yesterday with an att SIM card and it worked on their network.

Nope, your good to flash to your heart's desire lol
Quick question, sorry its a bit off topic, how did you guys get your phone unlocked?
I've read threads about Tmobile being friendly enough to send you a unlock code, but I currently have AT&T. Does that affect the process any?
Yes att does give out lock codes ... just have to wait a certain amount of days..and once unlocked always unlocked... flash away..

Unlocked s3 and wanting to switch to prepaid

hey everyone i'm new to this so please bare with me..I have a T-Mobile Samsung galaxy s3 and I got the unlock code off eBay for a pretty cheap price, so far it looks liked it accepted it . I wanted to switch over to net10 or simple mobile. I heard about if not paying my T-Mobile bill they will block the imei number. If so will I be able to use it at all on those carriers I stated, or will I just have to use it on H2o or Att.
Also as far as the apn settings is there an application that will help? Thanks in advance
Sent from my SGH-T999 using xda app-developers app
Just means u cant use the phone back on t-mobile other company's dont care if the phone has bad record I had and s3 before I got the one I have now it could not work with tmobile because the person that sold it to me did not pay bill but u can use it on att simple mobile net 10 any (gsm) cell phone carriers
Sent from my SGH-T999 using xda app-developers app
OK thanks a lot. Also I did hear that simple mobile is run by T-Mobile so will it work on simple mobile if Imei is blocked?
Sent from my SAMSUNG-SGH-t999 using xda app-developers app
Yeah it will work. Simple mobile doesn't even ask for imei. Only if you want to put it there is the option but its not required

Ok thanks alot for the info
Sent from my SGH-I747 using xda app-developers app
To be fair, they're going to know your IMEI even if you don't disclose it to them during the sign-up process. Just by using the phone it will send that information out when you communicate with their cell towers - so I'd imagine if T-Mobile shares its block list with Simple Mobile, it won't matter if you disclosed the IMEI at signup - they're going to know it anyway.
That, and the Big Four is actively working with the FCC on a cross-carrier database - so unless that falls through at the 11th hour, that's on the horizon in the next year or so.
Just sayin'.
What do you mean by the big four carriers is working with the fcc in the next year? Please explain, thanks

Yeah your right. I just called simple mobile and they said even if it is blacklisted for not paying my bill, it will still work because its an unlocked gsm phone so it wouldnt matter, just pop in my sim card and I would just honestly get edge network which is slower than 3g speed.
Sent from my SGH-T999 using xda app-developers app
It will work if they don't use T-Mobile IMEI blacklist and continue not to do so.
It seems like that's the case, at least for now.
Just saying, it doesn't have anything to do with if the phone being carrier unlocked or not - IMEI is tied to the phone's hardware, not the SIM card.
I went through something similar with T-Mobile, and most of the reps don't know what the block list is let alone how it works.

Using AT&T sim on blacklisted T-mobile GS III

Hey guys,
I got scammed on craigslist and the guy won't respond. So I bought a T-mobile Galaxy S3 and it worked fine for over a week until 2 days ago when it stopped connecting or registering to the T-mobile network. I found out from T-mobile it was blacklisted as stolen/lost that day. I called to confirm the phone wasn't stolen or lost when I bought it. The T-mobile store says there is nothing they can do except offer me a new phone from the store to pay full price.
Can I unlock a phone marked as stolen/lost using an unlock code and use it on AT&T?
I tried searching the forum and I found a thread about a guy who already had the phone unlocked so he was able to use it on AT&T but in my case, the phone is not unlocked yet but is blocked from T-mobile networks.
Thanks in advance,
Buzz
Well if you unlock it before the whole illegal thing starts you can use it on AT&T.

1111+ Thats correct I have tried every rom out there from att and it worked on my tmobile s3. Now for the op. looks for the thread on general there is one that shows you how to unlock your phone without a code. It was meant to be for the note2 but it worked on all us s3's I have mine unlock that way put in my friends att sim and it worked fine only thing that the speed its a little slower not 2G though. And thats because att's 4g its 20ish not 42.
Any ways. If you were called tmobile and talk to a superviser they can change the IMEI number on their system and the phone would come back to work in 48 hours.
I know because It have happened to me too. It doesnt matter if you have your tmobile sim on it for at least a day tmobile computers will register that phone onto your network.
P.S the only thing that will changed from a ATT rom is that build.prop It will show that its an att rom but you can edit it to d2tmo with root explorer
Just don't flash other modems from other carriers that will Brick you.

unlock tmobil s3 problems

I have an s3 that i was selling to mother in law to use on consumer cellular. T mobile provided an unlock code that does not work. They are supposedly investigating this. I tried to pay an online unlocker for a code, I told them the code t mobile provided that did not work, They were unable to generate an unlock code ,
What is is going on. T mobile sim locks phones and then cant provoide correct unlock codes??
What other option do i have?
This seems like a bunch of BS on tmobile part.
Selling to MiL ? I'd give for free if I were you.
Seriously speaking, you can take the phone to a T-Mobile store for further investigation. If the code does not work, don't try it repeatedly. The phone will lockup for good.
If the code did not work, make sure the T-Mobile Rep has taken down your IMEI correctly. Make them repeat it to make sure its correct.
There are other ways to unlock. But in order to try them, I need to know what android version you have right now. Its listed in Settings > About.
Its running stock rooted 4.3 with stocm recovery and some bloat removed. Have verified t mo has correct imei. Have tried 2 old centennial wireless sims and an old at&t sim. No luck.
Sent from my SM-N900T using xda app-developers app
Since you are on 4.3, the other way to unlock is out of question. Please take the phone to a T-Mo Store after you get the new unlock code.

I just got done with TMO online chat and they said to make sure the WiFi is off before you do it.
I am going to try this when I get home.
Check out chainfires Region Lock Away app on the play store or here on xda. Its built for the note3 on 4.3 firmware, but ive seen claims it works on the S3 and others. I suggest reading the thread to be certain, but it may be a viable option for those running 4.3 rooted.
