[Q] Galaxy S2 cannot sim unlock even WITH carrier unlock code - Galaxy S II Q&A, Help & Troubleshooting

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

[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?

Locked after updating

So this weird thing happened to my Bouygues Telecom Samsung S3... today I just updated it to version Android 4.0.4 and it now asks for a code to allow the use of my current SIM even though prior to updating I was using the same SIM with no problems. The idea is that my phone is now locked to Bouygues Telecom even though it was not before. If anyone could advise me how to get my phone unlocked again it would be greatly appreciated. Thank you in advance! =)

[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] Network Unlock

Hi All,
I'm hoping you can help.
I'm trying to get my Galasy S3 unlocked for GiffGaff in the UK.
I've tried all the dial pad service codes and nothing seems to work. I see Current Code 186, instead of what the guides show.
I've also flashed a few different ROMS in the hope the code would work, but nothing.
Is there a way to unlock this device now?
I used to be on Orange and am currently running an O2 based ROM version: 4.1.2
Many thanks in advance.
Logicalstep
If it runs on O2 it will run on Giffgaff as Giffgaff uses O2 .
Is your phone actually locked and to what network .

[Q] Galaxy i9300 || Unable to Network/SIM Unlock

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
