Must match IMEI under the battery .
Check IMEI is not blocked as stolen phone by the networks .

In that case there is something wrong as genuine SGS3 has label under the battery with product code IMEI SN etc .
Are you sure its I9300 what does it say in settings about phone ???

SORRY I EDITED post " Phone is not solen 100% my mother gaved to me.. EDIT i found imei under battery it is same imei as in status but when type *#06* i get ( imei number ) / 07 what mean 07 ? " Is there any hope for unlocking ???

Again check IMEI is not blocked for whatever reason .
Does the original network sim work ??

Same as my previous phone, i couldnt use it before I unlock it. When i enter my SIM card PIN number Phone ask me for SIM NETWORK UNLOCK PIN.

Imposible to find key, few moths ago i unlocked S2 with some app. Can I unlock it if I change software kernel or anything else ?

No. You have EFS v2. No apps can unlock. Impossible to downgrade to EFS v1.
1 option, buy unlock code

[Q] Problem with sinal

Hi Guys! First sorry for inglish... I'm speake portuguese.
I'm have a problem with my phone, i try install lots of custom roms and original roms and phone accpet chip (TIM) but dont get sinal...
My IMEI its OK. i'm use *#06# and my imei its ok... im look on black list, and my imei its ok too.
someone can help me please
When did that problem start?
What did you do right before that problem appeared?
You said stock roms, does it mean its same on stock based rom or on clean stock rom, like after you do repair software with pc companion?
Is your phone SIM locked, meaning locked on one network? Wad i locked before and you unlocked it?
Type *#*#73784236#*# in dial pad and go to servce info->configuration, what does it says: under rooting status?
P.s.: in future use Q&A section for questions. While posting this you even answered/mark that its a question

[Q] i9300 NV Data information.

After reading about how CDMA devices were able to have modified IMEI information, I was curious about the GSM variants such as mine, the i9300.
I've looked all over XDAdev and can't find information about modifying this version (which we have in the UK).
I have one which I want to manually corrupt the IMEI data on, the phone has a broken screen, but I can plug into a good screen temporarily. The phone in question is rooted but I can't remember what firmware its running, I believe it is JB (stock ROM).
Am I missing something blatently obvious or is it just not possible with the UK variant of the SGS3?
Thanks.
Modifying IMEI is illegal and as such discussion is not allowed on XDA .

Dont post IMEI or SN unless you want your details stolen .
#
One if locked it would be locked to sunrise / the original network .
Two baseband and csc would be different in a different country .
Suggest you hunt out a thread or forum that deals with your location for the correct firmware and modem .

because its mg4 already since i receive that s3 from sunrise
i'm sorry, since i'm newbie in android. but i want to learn much.

no, i'm still stuck.....
Didn't you used to be able to cut a section out of the sim and what identifies the sim lock in the sim no longer exists?
Well I phrase that as a question, but the answer is yes. The real question is whether that is still possible and whether it works with regional locks

yes, when the dialog box to enter unlock code appear, i can cancel it and there are no networks (sos call only). identification about region locks:
1. the label on the box about region lock
2. i bought the phone from switzerland, i try and it working well with switzerland sim card (i use this sim also for first activation) and also with italian sim card works fine, so it's not sim locked
3. with indonesian sim card --> no network, sos call only
4. bring it to samsung authorized dealer in jakarta, indonesia, they know about region lock but they reject the phone and say that i need to bring it back to samsung switzerland to unlock it
5. try regional lock away from @Chainfire but the app still doesn't work in my phone
until this moment there are still no solution, now the phone already rooted but still region locked......
I'm curious about the two different screens you're showing in images #3 and #4.
Did they result from different actions on your part?

Can be a MG4 Modem Be Unlocked by SimUnlock or another unlock method?

So i flashed a mg4 rom without EFS backup and now i have to use mg4 or newers modems forever . my s3 is from movistar(vzla) i have a UBEMI1 baseband right now (didn't have to flash a mg4 modem to make my signal or imei work) .. this is the newest rom from movistar mexico for i9300 released on october 2013 . ..
I used the galaxy sim unlock tool , voodoo , and some other tools , tried to use the samsung s and II unlock code generator by patching my data.bin and the results are the same .. when i open the galaxy unlock tool it shows my phone as totally unlocked .. but when i try another carrier sim it ask me for a PIN CODE . so don't really know what to do here for free unlock my phone ..
- i have no older modem efs backup
-cannot buy a unlock code online because on my country (venezuela) the dollar currency is ilegal (yeah a cocksucker goverment here)
So have u guys any ideas for me?
No you have to buy an unlock code. Dollars aren't the only currency in the world

I9300 4.3 sim unlock

Hello! I just bought a Samsung Galxy S3, and it's locked on Vodafone Romania network, running jellybean 4.3. How can i unlock it so i can use it on any network? Is there any free option? Or is there any site that provides an unlock code through payment? I'm willing to pay, but i don't want to get scamed, i want a secure site that any of you has used. Thanks

OK, so here's what i done by now. I managed to go back to a 4.1.2 version that has MG4 baseband (efs v2). afaik, on 4.1.1 you could unlock the phone through the service menu (#197328640#) method. Is it possible to downgrade to 4.1.1 with MG4 baseband and unlock the phone through the service menu?
