AT&T GS3 Sim Unlocked - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

I'm looking to purchase this phone and I was wondering if there is a Dialer code that I can use on this phone to tell if it's really sim unlocked?
Or another method of telling besides taking their word?
Thanks

OK after more searching I come to this
Insert a Straight Talk sim, then power on the phone.
If the phone is sim unlocked then it should load Android.
If the phone is locked then after powering on then the "Enter Sim Unlock Code " window will appear b4 booting to Android.
Is this information correct?
Thanks

Depends on the straight talk sim. If its the att sim, you wont get prompted. If its tmo sim, you will.

How long have you had your phone? I just got mine 3 days ago and a quick read through the manual said Verizon will unlock the SIM after 60 days of use. They at least want something out of having a customer purchase a world phone from them.

[Q] UNLOCK

TMO just sent me my unlock code. I bought a St8 Talk sim card. Put it in and it is not asking to enter the unlock code. How do I input this code?

3. Click/Tap in the empty field above the "Unlock & Dismiss" options (this will display a key pad on the screen).
4. Using the key pad input the Unlock Code provided by T-Mobile.
5. Press the Back button to remove the keyboard from screen.
6. Click/Tap the "Unlock" option; handset should display "Network Unlock Successful".
Please note that if you are unlocking a flip device please use steps 1, 2, 3 and 6.

Is the straight talk SIM T-Mobile or att? If it's T-Mobile I don't think you need to be unlocked.

I have a follow up question to this: Is there a way to unlock the device using the unlock code provided from T-Mobile while on cm10?

[Q] Can I use any Microsim card to unlock this device?

Hello,
I have a locked T-999 and I'm getting my hands on an unlock code. Can I buy any cheap microsim card to unlock my device or does it have to be AT&T?

I would think it'd need to be a tmobile sim, but I'm really not sure about that.

Insert any non T-Mobile micro SIM. You have to have a SIM that's not T-Mobile. T-Mobile s3 doesn't have access to unlock menu until another SIM is in the phone. At least it wasn't possible when I unlocked mine months ago

Thanks for the responses!
So I can just get this one (http://www.ebay.com/itm/NET10-MICRO...130794368103?pt=SIM_Cards&hash=item1e73f3ac67) and it is guaranteed to bring up the unlock menu?

or just go in to ATT and ask them to use one for a sec. Im sure if you tell them you need to unlock the phone to their network they will have no problem letting you use one for 30 sec.

Pre-paid SIM Worked Without Unlock Code?

I got an unlock code from AT&T, but I was never prompted to enter it after putting an H2O Wireless SIM card in my GS3. I'm able to place/receive calls and get data after entering APN settings.
My phone is rooted, but I didn't think it was already unlocked. Maybe I missed something. Any ideas? Thanks..

Did you buy the phone from someone else or an official retailer brand new in the box? If the former, someone may have already unlocked it. Otherwise did you perform the JB unlock method via the services menu?

I purchased the phone new from AT&T and rooted it a few days later. I never did the JB unlock.

Prepaid or postpaid... They all work as long as they are same phone service provider. Try a different network n see if that works.
Its a network lock, not a service/plan lock.

I guess that explains it, since H2O uses AT&T's network.

[Q] Issues SIM Unlocking Metro PCS GS3 T999N

I have bought a service to get an Unlock Code for my Samsung Galaxy S3 T999N which is SIM Locked by Metro PCS. They provided me with some 4 codes: NETWORK, PROVIDER, SUBPROVIDER, DEFREEZE.
When I turn on my phone with a non-metropcs sim, the phone prompts: "PIN to unlock SIM service provider" so I put the PROVIDER code that I got from FATSGSM after hitting "Unlock" I get the following message: "unable to unlock sim service provider"
What is wrong? Could the PIN provided by this service be wrong?
Just an FYI, I am outside the US right now.
Have you tried using the metro sim?

I don't have the metro sim.
Ok. Im not certain about it, but it might be required for the initial unlock. Hopefully someone else can say for sure.

Thanks for reply to my post.
This might not be true because if you have the Metro PCS sim card inside, you will not get the unlock box. You only get the box to put the unlock code in when you put a non-MetroPCS sim card.
Can anyone corroborate this information?

He means it may need to be activated with the carrier first in order to be unlocked.. Some phones do require this.. You can try the region unlock app but I'm not sure if it works with s3
Sent from my SGH-M919 using Tapatalk
I used it when I got my replacement S3 a while back and it said the unlock was successful. I have no way to test if it really was or if it also SIM unlocked though. I wouldnt expect it to do so, but in my experience, it is safe to try.
