[Q] Galaxy i9300 || Unable to Network/SIM Unlock - Galaxy S III Q&A, Help & Troubleshooting

I have seen a number of questions that are simular to this, but I have not been abe to find one that is like mine, therefore I am posting this.
I have a Galaxy S3 International version that was bought from Digicel Jamaica. It is completely paid for, I called Digicel to ask the for a unlock code. they informed me that they do not do that and I would have to go and get it professionally unlocked. the reason I want it unlocked is that I not longer live in Jamaica, but now live in the US and would like to use the phone for the next couple of months until I can get a phone on contract.
I have tried everything I have seen on this site, including getting a unlock key. nothing works.
I upgraded the phone 4.3 sometime ago and have also rooted it in the pass.
Whenever I try the *#197328640# , after [6] Network Lock I get no menu options see .
PLEASE HELP ME :crying: :crying: :crying: :crying:

I have also tried using RegionLock Away and Galaxsim Unlock, both tell me my phone is unlocked, but I still can't use another sim in the phone.
PS. I am using a T-Mobile Sim from straight talk

You can't region unlock on 4.3 at all, sim lock is possible but only if you buy a valid code -there is no other way and your posts are identical to hundreds of others.

I have a valid code, but the SIM unlock doesn't work with the code. I have tried everything I have seen online, downgraded to 4.1.1, replaced the stock 4.1.2 that came with the phone.... nothing works

[I9100G] Network lock

Hello,
I received a Galaxy SII I9100G as a present last april in Morocco (I'm in France right now). They told me it was an "unlocked" phone (not bought from any operator).
The phone worked wonders with my SIM card (SFR, a french operator) from april until 2 days ago. It seems like it locked itself all of a sudden and asks me a code to unblock the network. That same SIM card worked well the same morning.
Anyone to explain what happened? I'm confused since I don't understand how it can lock itself without having to change the SIM card/flash/anything...
I called SFR and Samsung France to have the code, each one tells me to call the other.
I rooted my phone and used Galaxy S Unlock, it tells me that the phone is unlocked but after the reboot nothing happens. Tried also Galaxy S2 SIM Unlock, but it doesn't find the code.
I'm quite desperate right now since I'm waiting for some important calls this week and I tried everything, every tutorial but nothing seems to work.
I really don't know what to do to unblock it, I asked for help on many forums, spent yesterday looking for solutions but still nothing.
Please tell me there's a solution to this problem?
Thanks in advance for any help~
Samsung Galaxy SII I9100G
Version: 4.0.3 - I9100GXXLPN
PS: Actually, it does seem to work with a Meditel (moroccan operator) SIM card... Which I don't understand since it was supposed to be unlocked, hence why it worked with my SFT SIM card since april...
Hey i think some persons before you has coneckt it with a Samsung account and locked it now over the samsung dive webside. You can try to flash a new Firmeware to fix it
First, thanks for trying to help me.
I already flashed it with a new firmware (2.3.6 >> 4.0.3, always using official samsung), but still didn't work.
Unless should I go back to a previous firmware?
Any other idea please?

I have a SAMSUNG Exhilarate(SGH-I577 AT&T) which my sister bring back from NewYork, and I want it to use my Chinamobile SIM card, and there comes the problem. When I insert my Chinamobile SIM card into the phone, it needs me to input "sim network unlock pin" ,but I don't have this number.
First what I'm thinking is to flash a rom, but this phone model doesn't released in China, I've been searched for 2 days, and finally find it's rom in this forum, I've downloaded two roms

My father always says that I keep learning from the forums and I never write anything. Well now something discovered by me. At least I believe so after browsing Internet for several hours.
I read the above recomendation of "kew1701" about flashing a modem of the t989 to the i577, and I thought: That will probably brick my i577 because the i577 is LTE and the t989 don't. It worked for the t769 because the t769 is not LTE either. And both the t989 and the t769 are for T-Mobile.
So I decided to give the try on my i577 with the modem I use to unlock the i727, the UCLD2. I assured my i577 was on ICS 4.0.4 and installed the modem with TWRP.
I originally downloaded that modem from here:
http://forum.xda-developers.com/showthread.php?t=2029650
(I thank that thread).
Followed the *#197328640# steps and it worked like a charm! Unlocked!. IMEI intact and all working. Now probably will flash back a i577 stock firmware, if I find it.
(My phone was on 4.0.4 UCLH3)
Enjoy.
Nice

[Q] Galaxy S3 Network Unlock

Hello guys,
I've tried to cut it short.
I would try all day unlock my S3 sim lock, but its failed every times. I am new in android customization so I read all things what I found, mostly the best hopes in here. So, it was an sim unlocked Galaxy S3 when I bought it, with android 4.0.4, I would like to upgrade it to 4.1.2 stock rom but it was some custom rom so its wont went automatically, I used Odin to Flash it with the stock 4.1.2 what I found here but it has the sim lock, I was tried more 4 unlocked roms but its stayed sim locked, I try all methods what I found but nothing worked, now the default IMEI changed.
Is it possible to homemade sim unlock it for free ?
(sorry for my bad english)

[Q] Galaxy S2 cannot sim unlock even WITH carrier unlock code

Hi All,
I have a Galaxy S2 which is SIM locked to the '3' network in the UK. I have contacted the carrier and they have provided me with an unlock code. However, when I am prompted to insert the code when I put in a different SIM card the code is rejected. I've also tried running the GalaxySimUnlock app which also came up with the same code that I got from my carrier.
My phone was originally updated to stock ICS but I then flashed it to CM 9 and then MIUI. I initially tried the sim unlock with MIUI running. I've now returned the phone to the stock 3 image - it's currently running 4.1.2 baseband I9100NELS1.
Has anyone had this problem before or can you shed some light on what is going wrong - I thought if I contacted the carrier this would be simple!
Many thanks,
Steve
Make your PC's network is sold. You have tried many software unlocking by noon?
Hi duykhanh187,
I'm not sure quite what you mean! I have contacted my carrier and have got what they believe to be a good unlock code but it is not working.
Thank you for your reply,
Steve

Samsung Galaxy S3 Unlock Issues

Hey guys,
I've been trying to unlock my phone for a few days now. Long story short, I moved from Canada to Japan and now I want to unlock my S3 to use a Japanese SIM.
I bought an unlock code from eBay. I was previous running cyanogenmod but then I was told that rooting will cause issues, so I unrooted my phone after an unsuccessful SIM unlock attempt. (wiped the phone, installed stock TW)
Even after unrooting I still had issues, and was given directions for the Service mode. That did not work either. I have tried many different methods and troubleshooting tips and nothing seems to have worked.
Here are some screenshots of the debug mode, my phone details, and a simple root checker app I installed.

Here are some specs: SGH-i747m Samsung Galaxy S3 on Bell running official firmware 4.4.2
Thanks for reading, and I really hope someone can help ;_;

My first thoughts are that since its from ebay it might not be a real unlock code.
I have had a lot of difficulty unlocking my GS3, as well. I actually got the codes from ATT, my carrier. I've tried 4 times, each unsuccessful. It says that after 5 failed attempts, the phone is forever locked to ATT, so I'm afraid to try that last 5th time. I was wondering if you could root, and then unlock more reliably. Is that possible?
Root makes no difference, you probably don't have an i9300 if you are on ATT.
