[Q] GSM locked problems - Galaxy S III Q&A, Help & Troubleshooting

Hi there.
I recently purchased an Galaxy S3 - i9300 from a guy and it's giving me headaches please help guys.
It was on Stock ICS 4.0.4 and working all good.
Once I flashed it with Stock JB 4.1.2 I couldn't make any more phone calls nor SMS ( GSM wasnt working). However data connection was working (I could go on WhatsApp, Skype etc).
I did a bit of research and it just turns out I bought a phone that was GSM locked. The IMEI it had before I flashed it wasn't the original IMEI and somehow it worked. Now that I flashed it with Stock JB I think it reset the IMEI back to the original one.
I know talking about IMEI change is forbidden to some extend but my question is this :
- Is there anyway for me to get my phone unlocked with the current original IMEI on Stock JB ?
- Would flashing a Stock Rom from a specific region solve the problem ? I flashed the first rom in this link from the forum, the one from Singapore - Asia.
- If not, what is the appropriate course of action here ?
Any help would be greatly appreciated.
I'm from South Africa and my carrier is Cell C.
Thanks.

Sure there should be a website to check if a phone is imei blocked. If so its an expensive paperweight...that is it.
Keep it legal.

If data connection is working then perhaps it's not a problem due to IMEI?
Could it be SMS setting error?
Because I have come across very same problem on a Galaxy Ace which phone call, data connection, all work except SMS can't receive and send...

Phone calls don't work on this one. It says emergency calls only and when I tried to make a phone call it says "Device not registered on the network".

What does your imei start with?

First delete the IMEI nr. In your post.
Make them something like :
353*******

OP would be very grateful for your advice,but could you follow it by yourself?
@OP: it seems to me that you have bought a phone from guy, who previously claimed it as stolen, or from the thief himself.
You have two options:
1. return the phone directly, kindly kicking his smartass;
2. return the phone via police claiming that you are the fraud victim.

[Q] Network Lock Status Code Not working.

Hey everyone.
I have the Canadian SGH-I747M model S3 from Bell Canada.
I try'd to use the Network Lock status code to see about SIM locks and *#7465625# doesn't work. Appearently it works for teh AT&T model I747 though so what does this mean? Is my phone completed unlocked and locks were never even setup at the factory to begin with or is there something else going on?
I try'd asking in the AT&T section Q&A but my question fell on def ears no one knows/cares.
Thanks.
Code works fine on international model.
Appears you device model just doesn't support the code.

No problem.
Sorry for a lowly User answering your question.
As I said, obviously the code doesn't work for your device model. Your model is not the international I9300, so your posting on the wrong forum anyway....
Maybe change your title to "Devs need only reply"
Edit: you didn't mention you new the code works for the international version, that's why I included the screenshot of what to expect.

You miss understand me.
I ment a dev or someone with more in dept knowledge as to why the code is not working such as the possibility of being with out any locks or something other then "oh well it just doesnt work with yours" not helpful . I also mentioned that the AT&T I747 model works with the code and it is the exact same phone hardware wise, only difference is slight changes in firmware by the carriers.
I have already said I asked in that sections Q&A and got no where, and so I am here looking for someone more experianced, I came here because the more experianced devs and knowledgeable people work on the international model.
Theres no need to be rude.
On the contrary mate, I deemed your response to be rude :banghead: We're all here to help each other
As I said, you never mentioned that you knew the code worked on our model ! Otherwise why I would post the screenshot?
Learn to be more specific in your posts buddy, then you'll maybe get the answer you need, and without wasting users time.
Sorry for not being off any help
Peace

How to make sure the IMEI of my S3 is legit

Hey guys,
I've recently bought the S3 from someone (2nd hand).
I would like to know if the IMEI of the device is legit and that it wasn't tempered with so i could in the future upgrade to JB..
can you help me out ?
Thanks in advance
Mike.
Firstly welcome to XDA.
Secondly, why do you think it isn't legal? At the top of this forum are some stickies which are available all the time for you to use. They cover a wide range of topics that are relevant to your new phone, not sure about imei number though!
Check out those stickies and hopefully most of your questions will be answered.
Have fun with your new toy

You really helped him.... Noot
You could check on sites like this if it was stolen:
http://www.amta.org.au/pages/amta/Check.the.Status.of.your.Handset
To check if imei is changed is almost impossible on phone itself. But if you got papers from first buyer then on bill and on box should you find imei.
But would help if you tell your country.
Sent from my GT-I9300 using xda app-developers app
ask him for the box or receipt.
kies, using the serial number and imei you can see if it exists and if it's related to any specific carrier

Hey,
Thanks for your reply.

What tool did you use to correct/change your IMEI?
Sent from my GT-I9300 using xda premium
You are only checking to see if the imei is correct right?
If so, dial *#06#, then check if it's the same one on the sticker on the back of the phone.

hy...i have a problem.how did you restored your IMEI???plss help.
Stupid to hijack a very old thread that has nothing to do with your question.
Restore IMEI is as per XDA flashing rule two backup your EFS .
So simply restore your backed up EFS .
No backup service centre is your next step .

don't you read the above 2 post ???
Try the "Firmware Upgrade and Initialization" in the Samsung KIES. It will reset everything according to your serial number provided.
However, I don't know whether it is helpful to you because I didn't experience the same before.

Your phone sounds stolen. You changed the imei, which is illegal and its against xda rules.

Our carrier name: Jawwal and its only 2.5G not even 3G
I changed the mobile network mode to 3G only because there is no lower than this but still the same problem.

terribly sorry. i of course am fine with it being moved but i need to get my camera back before i go overseas in 24-36 hours. if you happen to find a link that isn't capped at dial up speeds i will be forever in your debt.
Why would I have a link, I don't even have that phone?
If all roms are the same then it is probably your hardware that is faulty.

the camera worked pre-flash. my backup failed without an error message :crying:
do you think if i asked nicely/offered 50 bucks a technical support employee at the Samsung store\an Optus Kiosk would be nice enough to re-factory-ize my phone?
