I just tried, and I also don't have UMTS.
But I have "Debug Screen" in the main menu and all other menus below.

Did you try with a 4.1.1 stock firmware?

I'm new to this forum too, and here:

I found a lot of informations that could also help you. You have to root your phone and flash a stock firmware without lock as Memphis_ suggest, these guides lead you to unlock your phone (and more...).

Yeah you can easily unlock with GalaxSim Unlock app but you have to pay.

[Q] Unlock AT&T Galaxy S3

I tried to use the following route several times to unlock my GS3 with no luck. It is still saying no SIM Card. Any other ideas on what I can do?
Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF > (after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in [6] Network Lock then choose [4] NW Lock NV Data INITIALLIZ
Thanks..

You need an unlock code if you are trying to unlock it for another network, don't know what the steps in that method you showed is about but I believe you need an unlock code to unlock it as there is no software that can unlock it yet.
Here is a topic about the available unlocks.

Disregard.

It might not work with AT&T S3 as it says : " Please note that due to different hardware, US Qualcomm based GS3 (SGH-T999, SCH-I535, SCH-R530, SPH-L710, SGH-I747...) are currently not supported. Don't leave bad feedback, I can't do much without one of these phones in my hands ! * "

[Q] Cannot unlock AT&T GS3 with unlock code

I bought a ATT Galaxy S3. The seller called AT&T and got the unlock code. I popped in a Simple Mobile sim card and it says "SIM network unlock pin". I then entered 8 digit unlock code got from AT&T. But it did work. Still asking for sim network unlock pin.
Has anyone had same problem. Is Simple Mobile causing this problem, since it's a prepaid network? Do I have to use one of the big GSM networks sim card to unlock first then use Simple Mobile sim card?
Any help would be highly appreciated.

try this
it worked for me on my 2nd s3 running 4.0.4 stock ics (just got) =)
make sure no sim card inside the phone yet, if there is, just take it out
Dial *#197328640#

there won't be any confirmation just reboot your phone, put your sim back in, wait for about 10-30 seconds for your phone to pick up the network and kabaaam it is unlocked, the timing is important btw

Make sure the IMEI used to get the unlock code is 100% correct.
Secondly, if the phone has had previously failed unlock attempts on it, you may need to use a Defreeze code to reactivate an unlock attempt. The phone may be rejected the unlock code (even if correct) because of this.

Strange. I thought this was only for 4.1.1. It didn't work on my wife's 4.0.4 but worked on my 4.1.1

Without a SIM, my phone will not dial this code. I've read that if I just try thee Unlock code all 10 times, on the 11th time, it will work. Some Windows Phone forum said that worked for several people.

found this online and it worked for me

will this work with Android 4.1.2?

No. I have tried the unlock methods on the web that work for Android 4.1.1 on the AT&T Samsung i747, and they do not work on Android 4.1.2. I have been unable to find any accurate directions for unlocking this version, but there are apparently lots of people who will misdirect you to the old instructions for the previous version.

Hello,
Does anybody know how to unlock the tmobile galaxy s3? I have a prepaid plan so I can't call and ask for the code. Is there any other way I can do it for free? Thanks

That option was only available for versions below: VALL4.
If you are on 4.3 then you cannot downgrade. If you are on 4.1.2 then downgrade to older firmwares, you can find these in development forums.

You should be able to just flash the older compatible VALL4 modem for tmobile.
Then try same steps again.
Then flash the newest MK7 or MD1 modem after it has unlocked.
