Possible you can read the rules .
This is not the forum you want you do not have I9300/ I9305

Hum… I’m not quite sure. Have you tried contacting your service provider or Samsung directly? Sometimes (especially with legal issues these days) your service provider can be the best place to ask about unlocking your device.

[Q] GT-I9300 European Sim Model

Dear xda,
I have sgs3 i9300 from sunrise switzerland, on the box, its written: "european sim model" and "this product is only compatible with sim-card issued from a mobile operator within europe"
and its happen, i can use italian operator (3 italia) but when i inserted indonesian sim card (axis) its locked, emergency calls only, and the phone asking for "SIM network unlock PIN" or "enter network lock control key"
because i need to use this phone in indonesia,
i try with:
1. following this method http://forum.xda-developers.com/showthread.php?t=2176719 ; but after select [6] network lock, there are no menu again, even i already use 4.1.1 firmware.
2. some code are not working on this phone, for example *2767*3855#, *# 7465625#
3. i try to install indonesian firmware 4.1.1 and 4.1.2 but became lost my IMEI and generic IMEI appear
4. try to install swiss firmware again 4.1.2 mg4, and get back the imei, and also back to the initial conditions.
5. try to buy the unlocked code, but the code still not works
6. try to root and patched use ariza http://forum.xda-developers.com/showthread.php?t=2218428 but still unsuccessful
last conditions:
AP : I9300XXEMG4
CP : I9300XXEMG4
CSC : I9300AUTEMG2
android version : 4.1.2
baseband version: I9300XXEMG4
kernel version : 3.0.31-1314436 [email protected]#1

is it sim locked? or the hardware only compatible for european?
some body, please help me, i'm really frustrated with this phone.....

It IS SIM locked.
If you have updated to mg4, no tools can unlock.
Not sure if you can buy codes. Not really my area

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 .

oh, okay, edited already
yeah, the strange things is it seems "half" locked, because i can use another european operator sim card instead of sunrise

so, i need to roll back to what firmware?
4.1.1? is it possible? since http://forum.xda-developers.com/showthread.php?t=2377731 say that once i'm on mg4, i cant roll back
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.
thanks
No you can't roll back. Theres nothing you can do - except I cannot say for sure about buying unlock codes

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?

You should call the service provider (sprint) and ask for unlock code, other methods aren't guaranteed and may corrupt your efs partition, or you can give it to a technician, maybe he can unlock it using OctopusBox machine (if he have it).
