Phone is an S3 for T mobile running 4.1.1
I've been in phone unlocking hell for 4 days.
Closely followed the "free" unlocking in debug mode method-trouble was phone will auto lock back after a couple hours or calls.
Tried turning the flag on and off, factory reset, all kinds of stuff and still no luck.
I broke down and bought an unlock code but can't get my phone to prompt for it.
I can't seem to undo the service mode change or find a way to enter the unlock code.
The phoen will not prompt me for an unlock code no matter which way I try to reset it.
Have you tried to odin to latest jb stock ?

Are you inserting a non T-Mobile sim card into your phone? ( I am assuming that your cell phone is the t-999) That is the only way your phone will ask for the unlock code.

yes, inserting non t mobile sim- it doens't prompt for unlock code
If I root and flash a different rom does does it bypass all hte lock/unlock BS or am I still going to have to figure out how to get that code entered
Also tried reinstalling drivers from kias- just rooted phone-it wouldn't be much trouble to install a different rom if that is the fix.
also I bought an unlock code but don't see a place to enter it in
Not 100% sure but I was under the impression the simlock feature was null on sgs3. I have no issues with mine using straight talk wireless full unlimited ($45 per mth). Aside from that, if you can give me some info on what you have done I might be able to help more. There are a few settings that need to be changed as well as phone based service menu changes.

ok
Inserted foreign (non t mobile sim)
Got a prompt for an unlock code, which I didn't have.
Used Google, found a way that looked promising by going in the service menu.
*#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
Ok did that then phone worked. Kinda. It works for about an hour or a couple of phone calls, then the phone says "searching" and I don't have any network connection.
Also tryied turning the SHA256 back on, back off, intializing, every combination you can imagine, same result, phone doesn't work.
Bought an unlock code but can't get the pop up to come on to ask for it so I guess it is worthless.
Tried reinstalling firmwire via Kias. Same thing.
Rooted phone thinking that might be the answer. Worked for a day then same thing.
Spent countless hours on google and these forums trying to figure out a way to fix it.
is flashing a rom a solution?

Phone says "searching" at top
sim works fine on my flip phone
is it possible that my service provider put in incorrect internet settings and it is causing the phone to get booted off of network-phone and internet

What APN's do you have?
never mind got booted off again...
phone says "searching"
internet was off
this thing is crazy
It will work just fine then all of the sudden nothing-move sim over to my flip phone and it works fine.
It's like the phone is shutting itself down.
Have you changed your service address? Sounds like your sgs3 isn't finding the correct path to your new network. ....
In your Phone: Go to settings<more settings<mobile networks- then touch the option network operators to scan the available networks in your area, wait for some moment, let your phone scan, a list of available networks in your area will appear then, select the network name of your service provider to register it and you are done. You can restart fore more efficient use then.
This is from another site, I have cm nightly so my options are a lil different now. That being said after manually selecting my network with stock rom, setting my APN/WAP had no issues. With the cm nightly I didn't have to change anything. I'm thinking one of the os updates might have made it hard to access or change this option. Will try to grab a dev friend to look into this for ya.

My service provider is Cellular One.
I have three options
Select automaticly
Default setup
Search now
Selected search now
It has two
T-Mobile
311040
I selected 311040 and nothing....still got the "searching".
then selected "T-Mobile" and my phone connected to "cellular one".
please please please let this thing be fixed!
Ok we are getting somewhere.
Last night after I "registered" to T-mobile the phone did fine.
Today I stopped in at Cell one on the way home and told them I thought it was fixed and what I did.
She said that isn't good because I will get booted off when my bill comes because 50% of my useage has to be on cell one network.
So she scanned there at their store and set it to cell one.
I get back home and I'm booted off again. I tried to put it back on T mobile and I get an error now that says my Sim does not allow to register on this network.
Is there anyway to get ALL of T-Mobiles stuff off of this phone?
Would flashing a ROM do that?

Hi everyone!
Just received LG Nitro HD which was bought on ebay.com (USA). As I live in Europe I can't use AT&T so I had to buy the unlock code and I did so. When I received the codes (NCK, NSCK, SPCK, CPCK, SIMCK) the Life's SIM was already in and I was doing some setup (can't remember exactly what, but not in wireless networks). So I decided do not reboot the phone and use 2945#*930#.
When I entered the code I get in the unlock menu. I pressed Network lock and the new menu popupd. I've entered the NCK and phone says that the Unlock was successful. Than I tried to press other menu items such as SIM unlock, Corporate unlock,... but without any effect.
After that I decided to continue my "exercises" and went to main screen and I didn't saw the network connection.
Than I've tried manual search, automatic search, other SIMs (from other carriers) - the only network which the phone can connect is life but connection loses in a few seconds. BT and WiFi works perfect.
I've tried to flash 10i.kdz, 10c.kdz, 10f.kdz, 18f.exe, 20c.kdz - only 10s and 18f.exe can start, others stuck on bootscreen.
Please help me how to connect the phone to other networks and make signal straight!!!
have you entered your apn settings for your carrier?

No, but they are received automatically somehow (maybe they are flashed at SIM?) for all networks I've tried. And they are correct - I've checked it on operator's sites.
Insert any sim and do a manual search. How many networks you see?
Also verify wether it is on 3G only or anything other than automatic cause in some devices it sticks even after full flashing. If that fails, best case scenario, antenna problem.

With any SIM or without any SIM, with manual or automatic search, with "2G only" set or not set it could see only the network named "life"
So I decided (the day before yesterday) to disassemble it and see what is happened inside. And I saw that some wire was not plugged but only putted on the board. I plugged it and powered on the phone - and IT HAPPENED!!! All the networks where found!!! So I've assembled it back and the problem was resolved. Sorry, I was so happy and didn't wrote about it.
The problem is decided, case is closed. Thanks for everyone for help.
rofl, yeah plugging your antenae in is kind of important
Hey everyone!
So I picked up a tmobile s4 to use on ATT since I read it was the most unlocked due to bands / bootlocker. I unlocked it via the method described on this site via the debug menu.
Popped in ATT sim, everything looked fine initially.
1. I'm only getting 4G in an LTE area. device hasn't picked up any LTE anywhere yet.
2. When I go under "Network Mode" and select "LTE/GSM/WCDMA (auto connect) the signal dies out and it always reverts back to GSM/WCDMA"
3. I've called ATT a few times and triple checked that I'm on an Android LTE data plan, so that's not an issue. ATT techs suggested it could be a device issue and maybe I should take it into their tech center.
4. Tried to set up ATT Visual Voicemail, that failed also.
So can it be a Sim issue? Maybe something on tmobiles side? Since device was never active on their network. A lemon S4?
I've run out of options
Any help would be appreciated.
TIA!

Thank you!
I also found the setting from here:
https://www.youtube.com/watch?v=gMyD8zqk-Hg which led to here: http://forum.xda-developers.com/showthread.php?t=2336085 .
The main end game fix was that ATT had my IMIE # incorrectly set. Once they fixed that my LTE was a go!

I have an S3 rooted with 4.3.
I have a Metro PCS sim which I am trying to use with this phone.
The phone seems able to read the sim OK.
Under status I can see my phone number.
Everything else is unknown. Network is unknown, Mobile network type is unknown, service state is out of service.
I get full signal too, but when I go to mobile networks, I receive a message "Insert SIM card to access network services"
So I can see my phone number, and I dont have a message telling me to insert sim when I start the phone.
I have checked with Tmobile and I know the phone is not black listed, but when I make a call I get not registered on the network.
I do see also my IMEI number and seems to be correct under about
I really dont know where else to look for answers. I would love some help with this.
Any ideas?
Anyone?
Do you have the 4.3 modem? And also did you add the device to your line? Otherwise it won't work no matter what you do

The Baseband version is T999UVUEMJC.
I tried to add this phone by contacting Metro, and they told me that they couldn't because the phone is locked. I contacted T-mobile, and the person sent a request to get it unlocked, and said that I should wait 72 hours to hear from someone. I waited more then 72 hours, and I called T-mobile again, and then I was told that I needed to have service before they could unlock the phone. I was not sure if that was the issue since the phone did not give me the invalid sim card error.
I went to Metros site to see if I can check the IMEI. Their system said the phone was lost or stolen. I called T-mobile to check on the IMEI, and they told me its fine and there are no blocks, and ready to activate.
I also confirmed the status using both Swappa, and checkesnfree. They both say the phone is ok. I would think just using the Sim should work, but I am not sure what to believe.
Ok there are 2 things you need to do.
1) update your modem to a 4.3 modem
2) add the device to your line.. Just swapping sim cards will not work. It also doesn't need to be unlocked.. Any T-Mobile phone will work with metro as long as its in a gsm market, so you might want to try doing it again.. I worked at metro so that's how I know all this
Edit: never mind you do have a 4.3 modem my mistake for reading too quickly.. But it looks like you're set to go, you just need to add the device to your line, so try adding it again

Also I wanted to come back and say that wasn't the only thing I did to gain access back to the service menu, I wasn't able to access the service menu due to no mobile network found. So I took the sim out and rebooted the phone. I then, to my surprise was able to access the service menu without getting the the no mobile network. From there I was able to go and change the setting I fooled around with back to the original settings. Then I rebooted the phone put the sim back in and it was fixed.
So to anyone who cannot access the service menu because of the no mobile network you can try to take the sim out and try it without it in...
Hi,
I recently went to India and thought it would be cheaper there to get my note 2 unlocked but, the person who tried unlocking my device got mad at me as my phone was rooted. He said, everyone wants to be a developer nowadays and thus it made his job harder. He asked me the model number of my phone as it shows GT-N7105 because I have DN3 v 5.2 installed but it is actually sgh-i317m from Telus in Canada. He gave up and said he was unable to do it. After coming back home, my original sim that I have been using in the same phone, does not work anymore. There is no network. My wife's sim card, which is from another provider, works now though it never did before. I though there could be something wrong with my sim card so I tried it in an old phone and it works perfectly in it. What would you suggest, I should do to try and resolve this problem? I am thinking of erasing everything from my phone and factory resetting it. Eagerly waiting for your expert suggestions!
Just to add: I chose factory reset option from under the settings menu and wiped all my data but it still does not work with my sim. I also, went under the available networks settings, chose the option to search networks and then selected mine (telus) but it say's no service (telus) not available. There is another message in the notification bar, which reads "data roaming: You have lost data connectivity because you left your home network with data roaming turned off". I am not sure if that tells you something related to my problem but I though I should mention that as well.
