Step 2 - We've got our code, time to enter it. To do this, we either boot up our phone with our AT&T micro SIM or dial "#7465625*638*# in the Phone app. Once you have the dialog box, enter in the unlock code from step 1.

Where do people get unlock codes? Do you need a friend who works at T-Mobile?

you just go on tmobile .com and do a live chat and request your code.they will ask you for the phone number, model number, and imei number. then ask for a email then they put a request in and within a day you get a email with the code.

not sure why my whole message didn't go threw.what i meant to say is my phone is stock...the only thing that i have downloaded besides games is the go launcher app...
i have tried to unlock my phone and when i do it says unlock unsuccessful...and in the directions the button they tell me to click will only come up with a different sim in the phone according to the tmobile rep.but i dont have another at this time.

I am sure you have friends that have ATT? OR go to a store or WallyWorld and ask if you could get a att sim.
Or.. if you ask REALLY nice in the Wanted section. I am sure there is someone who downgraded to iPHAIL5 that has a spare micro sim. Since the new iPHAIL uses nano sim.

i would rather use an Att sim.where i am in jersey att seems to have better reception.will my t mobile s3 work with the st Att Sim?

If you entered the code your probably unlocked. I would get the same response. Get a friends att sim card and put it in your phone to see if it works. That is how I tested mine. And it worked flawless.

[Q] SIM Unlocking

I was wondering if there was a way to unlock the Galaxy SII for free. I know that you can use like adb to unlock the MyTouch 4G Slide. Can something one do something like that with this phone?
btw, I tried the "Galaxy S Unlock" app from the Play Store, and it didn't work.
Do what I did. Call tmobile and tell them that you are leaving the country for a while and want to use a different carrier to avoid roaming charges. Bam. I had my unlock code within 24 hours.

yeahhh. I know about that, but I don't like how you are supposed to wait 3 months in between unlocking. and i might actually leave the country in less than three months. and the other phone is neither unlocked nor rooted.
Nope, only way is to call T-Mobile for a code....or a third party vendor

either get teh code from AT&T (if you're a customer) or pay $25 for it at one of the unlock code sites. there are no 'free' options outside of the carrier.
To get the code from ATT, dont you have to pay the full price of the phone though? Also, if you do the 25$ unlock code thingy, does the unlock stay forever (even if I do an update or change ROM's)?

No, I got my code from At&t after owning my device for 40 something days through upgrade and unlock stays forever ...even when OTA or ROM changing.

Why not tell your carrier that you are going overseas and want to use your phone and ask them to unlock it I did and T-Mobile sent me the code for my phone at no charge. My problem is coming up with a non-tmobile sim card.
thanks but i tried that a while back. no such options for me

[Q] s3 downgrade help needed

I recently acquired a t-mobile galaxy S3 (t999l)running stock 4.1.2, however my current provider is metropcs and in order to use it i have to unlock it. I currently dont have the money to pay for that so i want to downgrade it to 4.1.1 to do it for free. I was wondering how i could go about downgrading step by step. I would also like to have it rooted.
There is no 4.1.1 for t-999l.. And you don't need to unlock T-Mobile phones to use them with metroPCS.. I know because I've worked for metroPCS.. In other words, you're good to go!!

4.1.2 is all we have

I tried putting my already activated metropcs sim card in and it asked for sim unlock code. Is there anything I can do to resolve that.

What phone did you have before? Was it cdma or gsm? It shouldn't ask for one.. also is your area using cdma or gsm 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.
