Why don't you try instead of waiting for a user with a locked phone to read your post it may be a long wait .Or a Google ask may return an answer .
jje
You don't even have to google it or ask here, ask borrow your friends SIM card, better yet from different network operator, and insert it into the phone, you will know

"Unable To Register on network"
I have a really annoying but strange issue I cant make phone calls or send and receive text messages but I can browse the internet.
I have a Samsung Galaxy S3 which im sure is sim unlocked 100% sure. It has been working ok up until recently something has changed but Ill be dammed if I know.
I am using 3ITA sim
Im running the stock ROM ..I tried to re-root the phone but this did not work.
I have done a factory reset this has not worked.
If I take the sim out of the S3 and put in into another galaxy s3 it works fine. I can make and receive phone calls.
But soon as I put it back in the S3 it says "Unable to regsiter on network" so it HAS to be the S3 but im sure it is sim unlocked!
I tried similar to this: (But when I got to network lock it says on my S3 (MENU NOT EXIST PRESS BACK KEY Current command is 186) what does this mean???
================================================== ============================
"Put in a different SIM card to the one you use with your carrier.
Switch the device off and on again with the SIM card in place.
Open your dial pad and then type in *#197328640#.
Go to Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF > and wait 30 seconds or so.
Then hit Menus and choose Back. You should now see Network Lock. Then choose [4] NW Lock NV Data INITIALLIZ."
Please can someone help !!
Hi
I had the same problem a few days ago. Really annoying.
What i tried was the following:
It happend after having flashed cm-10.1-20130211-NIGHTLY-I9300.zip
It stayed like that after having flashed cm-10.1-20130208-NIGHTLY-I9300.zip
It was solved having flashed cm-10.1-20130129-NIGHTLY-I9300.zip, GAPPS and having wiped Dalvik cache, cache and i wiped back to factory.

Well, I just had this probleme again.
Don't know what is happening.
This time it was with the cm-10.1-20130303-NIGHTLY-I9300 but it persisted through cm-10.1-20130311-NIGHTLY-I9300. Full wipe solved it for me.

I use a galaxy s3 i747 which previously having a Carrier at n t. After I came to India, I unlocked it on hands without using any unlock codes. I just followed the below steps to unlock it.
Just dial the following keys *#197328640#
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 ..... wait for a minute then reboot your phone.
I unlocked it successfully and it's working with 2g,3g and 4g lte also on all carriers within India.
Recently at n t has given an update for this model to an upgrade for Android 4.3 jelly bean. I want to know the issues updating my phone to 4.3
Will I be able to update it from at n t servers after unlocking it?
Will my phone get locked once it is updated to 4.3?
Will I be able to update my phone through any other sources?
You are on the wrong forum my friend. You should go to Android development or Galaxy S3 Development forum. :good:
thanks

Hi for the past 1 week I have been trying to unlock this GS3. went from 4.1.2 to 4.0.4 still nothing, to paying unlockers for sim unlock codes. Nothing seems to help. Not even the Main Menu
[1] UMTS
[1] Debug Screen
[8] Phone Control
[6] Network Lock
Options [3]Perso SHA256 OFF
the Perso part menu dose not exist
network providers here in my country wownt try to unlock ether. Is there any other method to unlock this G3S GT-I9300 Ver.
So if finally downgraded this too 4.1.1 So i can use service mode. These are the steps in service mode.
1. Type *#197328640# and it brings up the factory service menu
2. Select (1) UMTS
3. Select (1)Debug Screen
4. Select (8) Phone Control
5. Select (6)Network lock
Right as i click Network lock i get zero options.. theirs supposed to be something like this..
6. Inside the Network lock menu, Pick option (3) Perso SHA256 off
It isnt there can someone please help me out with this. Im so stumped i just bought this phone for my att service but this is Us Cellular. Any help in the future will be greatly appreciated! Thanks.
No one ever figured out a way to do the unlock on that model. I'm sure it wasn't for lack of trying. Have seen plenty of other thread requests like this that were never solved and the phone has been out for awhile now...
this should work on galaxy s5 rooted
how to enter service mode and change band setting and maybe someone smart to sim unlock
i already paid to unlock my sim,so i cant test unlocking sim.
