I want to use S3 with other carrier (e.g. ATT, or other countries), does it rooting and install a custom rom (e.g. CM10) will achieve this? or i still need to get an unlock code from TMO. My apology for this beginner's question, need to know before I travel. thanks.
You will need an unlock code from tmobile to use phone on another network.

My current S3 is locked to Rogers,
I really don't want to go to a carrier unlocking site like cellunlockerdotnet to unlock my phone. I was wanting to know if there are any developers here have any insight on this, whether there's any hope of there being a tool that will unlock it from Rogers (that I would be more than glad to donate to) or if I and others should just risk going on said sites?
On a side note, I'm curious as per why these cell unlocking sites have the ability to send unlock codes and there hasn't been anything here to do so? I'll be glad to provide all the information of my device to move forward with any Canadian SIM unlocking tool that may be in progress.
Ok guys, I have a quick question. I bought a T Mobile SGS2 brand new and will be unlocking it with which ever site I can find to buy the code off of. But my question is that, if I root it and flash custom roms on it and all that we do with our Android devices, will it be locked again after a flash or root.
Reason why I am asking is because I will be sending this phone to a family member outside of US but before that I will root and flash CM10 on it.
So can someone please tell me if it will stay unlocked?

Once unlocked - forever unlocked, no matter the Rom.
To unlock, you need to be on the original T-mo Rom and you
can request from T-mo Tech. support the unlock code for free.
Awesome news, now.I wont have a problem sending the phone. Thank you for your response, appreciated.

T-Mobile will not unlock
Hello I just wanted to let anyone who stumbles across this to know that T-Mobile will not unlock the phone if you are not currently a T-Mobile customer. I was able to unlock my phone using cellunlocker.net for $25.
Hey guys i'm new to this forum but i have been having a very frustrated time i really wanna unlock my FIDO galaxy s3 i know it's not listed here but, i want to unlock to so i can use my rogers sim card can anyone give me any tips how to do this i don't wanna pay for a unlock code
You must be running stock 4.1.1 to use the free unlock method. If you are running 4.3, you will have to buy a code.
If you have to buy a code, you may have to return to stock to enter the unlock code.
Hi to all, im new on the forum, i was looking to find a way to unlock my S3 t999 which has the android 4.3 JB, i got a lot of info but it seems that i only Rooted my S3, i found out that there an easy way to do it whit the Service mode but since i have Stock 4.3 its impossible, was looking a way to downgrade to 4.1.1 but probably ill get a brick, so if there any way that i get some help unlocking my device i sure will appreciate it.
After 4.1.2 I think there is no free alternative available (unless your carrier gives unlock codes for free after a certain time period). The best way to unlock your phone would be by contacting your carrier for an unlock code which usually means paying a fee or using a pay service. I would recommend using your carrier because they will offer better support and this would reduce your risk of getting scammed by a online service.
Help please!
Hi! Where do I begin?! So I have a tmobile s3 T999LTE version. Previously I rooted it because I wanted custom rom on my phone. Then I wanted to sell it so I unrooted it. I had read somewhere that after unrooting I should revert to latest stock firmware which was 4.3...BIG MISTAKE! It's now running on 4.3...LUVUBOH1 and I CAN'T UNLOCK IT! Tmobile had sent me a code which did not work, then I switched to metro pcs and purchased a code off ebay,which was the SAME code tmobile had given me. I now have metro pcs on another phone and when I put in my current sim in s3 it doesn't prompt for code! And no key combos are working due to change in dialer. I am stuck and gave no idea how to fix it. Imei is valid and I'm pretty sure I'm running stock 4
3. Help anyone? Please? ???
Was the phone running a completely stock rom when you tried to enter the code? How many times did you try to enter the code?
So I'm currently in Europe and I will be here for 2 more months and I would like to unlock my phone because $4.19 a minute is ridiculous. However tmobile support is being, let's say very smart. The first representative said "just visit you're nearest tmobile store and we'll help you out there." After I had already told them I was in a country without tmobile. So I was wondering if there was any way to do this for free? I really don't want to have to spend any more money right now. I'm currently running liquidsmooth lollipops latest build. And I really don't want to have to revert to stock because I currently have Internet speeds of 85kb/s and that would take ages to download and then reset up my phone. All help is greatly appreciated.

Which version should i downgrade to, and could you give me a like to a method of unlocking it?
Before flashing any TW ROMs via Odin, confirm the bootloader and modem on your phone.
I'm not sure but if the T999 is like the i747 (ATT s3 version), you cannot downgrade the bootloader from 4.3 to a lower version. Doing so may brick the phone.
If you are on a 4.1.1 or 4.1.2 bootloader, you should be able to downgrade to stock 4.1.1 and you may be able to unlock for free using this method: http://forum.xda-developers.com/showthread.php?t=2014982
If you cannot downgrade to stock 4.1.1, you'll need to buy an unlock code and enter it using a stock Samsung dialler.
