Here's the issue. I purchased the At&t s3 (SGH-I747) last year. Long story short, I wanted to go to T-Mobile prepaid with the same phone.
I purchased the SIM activation kit for $10, popped my SIM in and it worked!
Before I put the SIM in it though, I paid for an unlock code. I still have the code.
No 'Network Unlock' screen.
No prompt for my unlock code.
I am getting H+ speeds with the at&t s3 on T-Mobile prepaid without doing ANYTHING.
My question is:
Why cant I get to the unlock screen? I have tried to dial "#7465625*638*# for the prompt to popup and NOTHING.
Can someone tell me...
1. Can I flash a T-mobile rom to this phone? (every time i try I get a build.prop error, even after changing the model to the T999 and all that jazz),
so I can't install a T-Mo rom?
2. Do I have to flash a modem/radio or anything else like that?
3. Or, should I just continue to flash At&t Roms with the t-mo prepaid sim?
I have searched for a while now, and noone has my problem. I never expected to just switch sim's and it would work, so ANY help would be appreciated.
Thanks!

in the general section is a thread on converting an i747 att to a t999 tmobile
Hello.
If you have signal then why are you trying to use the code? It is unlocked already!
im not an expert but this is what i know from reading a lot:
1.- I installed a t-mobile (t999) rom modified to work in a att s3 (i747), i think you can flash a any rom from the t999 section (i am not sure about this)
2.- Do NOT try to install a modem from t-mobile or you will hard brick your phone.
3.- Thats a good idea, do it and let me know if it works.
I used this files to convert an i747 to a t999 http://forum.xda-developers.com/showthread.php?t=1771021&page=25 (read from post #246) so now i use customs roms for the t999 i did it because where i live do not have good signal, was stuck at edge and with those files now i have 3g signal.
Btw, i am in the $30 prepaid t mo plan.
Thanks all!

Thanks to everyone, and I definetely will try the above.
Thanks again, all!:good:
Hello,
So I used the instructions from this thread to unlock an ATT S3 for international use. I don't have the international SIM yet and currently have Sprint so I don't have a SIM card. I used my old T-Mobile sim and get the "SIM not provisioned MM #2" message. Would this mean that it is unlocked?
I am buying a Samsung Galaxy note 2 from craigslist. The post said the phone was locked to telus/koodo and so I messaged them saying that my simcard is from fido and would like to buy it than
unlock it so I could use it. He messaged saying he tried Rogers/bell and it wouldn't work and he doubted it would work with fido ( I don't know if he knows what he is talking about
because the post said it was locked ) and so I asked him if it was unlocked already or was it just locked to telus and koodo because I heard you could put a koodo sim card in a
Telus phone. He also said maybe the sim card reader is broken, but I thought if the sim card reader was broken it wouldn't be able to read any sim card at all not even telus sim card that it's supposedly
locked to. The phone is model SGH-I317M. I really want to buy this phone and it was the best one I found on craigslist. I am thinking of going to test if it is unlocked but how do I tell? Will a message pop
up when I put in my fido sim card in and boot it up saying "phone is locked, put in unlock code" ? :crying:

Yes a message will pop up asking you for the sim unlock code if it's locked. If it's not locked then you'll get signal. You also need to ask them what firmware is on the phone, cuz you can possibly unlock it from the hidden menu. Just search Xda for that.
Good luck on your new device ?
I'm wondering how are the carrier firmwares provisioned in the Canadian model (LG-G710AWM). I purchased mine through Fido.
Do all carriers get their own firmware, or is it provisioned by the SIM card. Like for example, if I install a Telus SIM card into my Fido G7, it will prompt a reset to install Telus customizations?
I recently switched from T-mobile to Verizon , tried to use Verizon SIM card on Note sm-n900t, but Verizon network is not recognized on phone.
the phone is T-mobile unlocked , is this because the base-band firmware on the phone still T-mobile specific? How to fix this?
thanks
