How to Manual unlock AT&T S3 I747 4.4.2? - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

I just bought a phone from a friend today Galaxy S3 4.4.2
so how can i unlock it without paid online because I dont trust any of those and dont want to spend money too.
There are some posts told about downgrade to 4.1.1 however, there are some people tell me not to do so because 4.3 and higher cant be downgrade or my phone become brick.
so is there other way around?

Is your phone running a stock 4.4.2 or a custom 4.4.2? If it is running a stock Samsung 4.4.2 ROM, you will have to buy a code.

AT&T 4.4.2. It is not custom ROM

You can only unlock the phone using a code.

[Q] Unlock to ATT phone to tmobile custom rom?

Hi I just unlocked the note 2 att version by downgrading to firmware 4.1.1. Now I can use the phone for t-mobile. I now want to root and have t-mobile based rom installed.
To achieve this must I first odin flash t-mobile's official 4.1.2 firmware and
then root and then install a t-mobile 4.1.2 based custom rom?
Or can I simple root and just install a 4.1.2 t-mobile custom rom?
Thanks!

First, why do you need a T-Mobile ROM? Is it for the wifi calling?

I have it in Note3 and it sucks...
I also have unlocked Note2 and it works fine on T-Mobile.
Do not odin the T889 firmware. Keep your current bootloader and modem, flash a tmo rom via recovery. Problems can be addressed in the rom thread.
Hastily spouted for your befuddlement
This ROM should work

stock FW are not smooth at all.
If you want to have pretty old phone running like it was designed 1 month ago just go with custom ROM, for start try dr. ketan's 4.4.2 V14
4.4.2 is the smoothest one in my opinion. I disable several bloatware by the way.
Happy with my kitkat.
4.4.4 touchwiz - no alternative, smoothest of all

i was just wanting to know if their is a way to root the s4 metropcs version. i'm on android 4.4.4 with kernel 3.4.0 and people told me about CF-Auto-Root but my bootloader is locked so that won't work. then i heard about towelroot which doesn't need an unlocked bootloader. do you think towelroot will work? it said that it should work on kernels lower than 3.5.5 which mine is but it says android 4.3 though. any help would be awesome!! thanks!!!
