blatz729 is completely right
Just don't loose the unlock code, after flashing a new custom rom just apply the code to the phone again and your good to go!
Extra: Your very lucky to get your phone unlocked. Congrats!
The phone shouldn't become unlocked, no matter what. If it does, however, the unlock code you recieved will work again as its hardware, not software based.

Dears,
I buy a I747 and bring back to my country to use so I already unlocked it (using N3X cable)
Now I want to flash new rom such as CM10 so do I need to unlock my phone again after upgrade ?
Thank you
You shouldn't have too. Once unlocked, it should remain unlocked. I've flashed every single ROM so far and my unlock has remained in tact.

I just performed a stock recovery to unlock my phone. I have successfully unlocked the phone. Can I root it and install a custom ROM and have the phone remain unlocked?
Yep. Your sim unlock will stay permanently.

This might be a stupid question but I want to ask anyway. I just bought a T-Mobile Note 2 and am awaiting a sim unlock code (I know I can downgrade to 4.1.1 and unlock it via the hidden call menu but at this time I am not opting to do that). I flashed the 4.1.2 Root Injected Stock Rom. My question is, (which maybe I should have asked before hand) Will I be able to use the sim unlock code that T-Mobile provides me with despite being on the root injected 4.1.2 stock rom? Thanks!
No issues, I did it and it worked for me.

Hey guys, just a heads up, if you are running 4.1.2 there is NO WAY to unlock your T-Mobile Note 2 without downgrading to 4.1.1 as far as I can tell. Even if you receive an official code from T-Mobile it will not work because when Samsung patched the security hole in 4.1.1 which allowed people to unlock their device manually they (accidentally) blocked any way of sim network unlocking. You can read all the complaints on the t-mobile website forums. So, with that being said you have to downgrade to 4.1.1 with Odin and access the hidden menu from the dialer. Just search the threads and you will find easy instructions.
NOTE: When you downgrade to 4.1.1 make sure you do a factory reset from recovery before you flash via Odin. After you flash the ROM your phone MIGHT go into a bootloop/hang on Samsung logo. Just go back into recovery and factory reset again. Give your phone about 4-5 minutes to boot up, just sit it on the table.
YMMV.
Thanks a lot for the tips but I downgraded before and it didn't work.
I still have a backup of the rooted 4.1.1 stock ROM. That's how I downgraded and tried to unlock but nothing happened.
Do u think I did something wrong or is there another way?

Is there anyway to Unlock the Samsung Galaxy S3 T999 with Android Version 4.3 , I tried everything , Downgrade Firmware , Change Modem to UVLJC and nothing . Help please
Flash a 4.1.1 or 4.0.4 ROM and modem (not Odin, or you will brick), then follow the unlock guide.
Alternately if you have the phone thru T-Mobile they will unlock it for you if the bill is current, or you can buy an unlock code online for under $10.

It doesnt work that way either. It lose the imei with a different MODEM, you need to flash it again the New Modem to recover the IMEI. Please I need to unlock this device. Any ideas?
Where 4.3 is concerned, there is no way to unlock using any of the previous methods. Your best bet is to call T-Mo
Im having problems sim unlocking as well. T mobile sent me a code that does not work. Still waiting on there help. Suggestions?

Well after calling TMobile again and spending close to an hour on the phone they escalated me to "Someone Will Call You Back" LOL
So Today I downloaded the stock 4.1.1 and loaded with odin. Then Used the steps in the below thread to obtain sim unlock without TMobiles help.

sim unlock 4.3
You only have two options... Option 1, You wait until kikkat 4.4 become available for upgrade then unlock the phone with same code. Or option 2, you find the stock rom that came with the the phone which is the ice cream 4.04. Then use odin to downgrade and then you can use the same code.
