Trying to unlock but get not registered to network error - Galaxy S III Q&A, Help & Troubleshooting

Evening all,
I'm trying to unlock a friends SIII, which she been passed down. I believe it was on Orange and is still locked to them (don't know for sure), I've put my Lycamobile sim in and it comes up with sim network unlock PIN I was going to try the free method of typing in *#197328640# but all I get is an error saying not registered to a network.
I've tried using Kies and picked upgraded and initialisation, it did already say it was update but thought I would run it anyway but still no luck. Could anyone offer any advice. looks like its running 4.3.

Advice is go buy an unlock code, nothing else will work.

Ok thanks, I will have a look.

Which model number do you have? Unlock procedure ia different for Qualcomm and Samsung basebands, you can figure out which one you have from the model number.

Hi guys,
My friend can send (Austria) me this phone but is sim locked.
Is there good way unlock the phone?
Docomo unlocks at point of purchase for a fee.
Check provider to see if they will also.
I'm buying from a friend, so it will be locked to O2, what's the easiest/cheapest way to have it unlocked?
Thanks.
O2 send the unlock code free of charge on request, it took 17 days for mine to arrive but no questions asked and it worked.
Ok, cool. Do you just call them up? Or pop in one of their shops?

Andy O2 models of the phone have a bootloader that's locked and it's not unlockable yet. You testing just using the phone or you considering to hack it?
At the end of it all, I'll be reviewing it. I did want to put ICS on it though. About 15 minutes ago I've seen the bootloader of this can't be unlocked though
Nothing that can be done?
**EDIT** Sorry, silly me, you've said not unlockable yet Thanks.

One thing you can do though is to use the flash tool to flash the latest update..73 has had positive results in improving battery
I think it is already .73
**EDIT** It's not, downloading the update now.

How can we do this?
I've been reading all over trying to figure it out!
Also, I'm guessing T-Mobile would try to charge for Unlocking the phone?

Believe so. When I boot up it has the T-Mobile logo.
I'm having real issues with lag and Xperia Activity Home force closing and the phone completely locking up, so I'm hoping I can stick .73 on it.

unlocked t-mobile

hi s3 owner here in the uk...simple question is i have the quad s3 on the t-mobile network...i cant believe that they havnt locked there phone...
there is no t-mobile start up screen or even t-mobile apps...is there a way to check if it is unlocked apart from trying different sim cards...ie like a code you enter...
sorry for the dumbness of my question....ohh and keep up the good work
Whr r u from?
Got mine from Vodafone, and its branded. Not locked.
Same in T-Mob case, they r just branded. Bootanimation etc is Samsung stock, u should just have some "T-Mob-Special-Apps" in your Appdrawer.
Im Using T-mob Germany Card in my VF-Phone, just choose your Networkprovider under Settings and everthing is fine

is that the right code getting connection problem or invalid mmi code
which firmware it has now?
Mine too (in AUstralia Voda), at first I was on stock firmware and network locked.
I swear I can execute that code, and I even unlock it using voda's official unlock code.
Now I am running CheckRom v3.5 based on BLFB and I get the invalid mmi code.
Someone said need to use stock dialer. But I thought my dialer is stock.

[Q] can i get the 8 digit code free if i have my imiei for my note

If there is a free site I beg for help
yes, at&t customer chat gives you the code for free.
Important to know that you need to be on the stock att Rom to unlock your devise. Simply entering your code into the dial pad on a non stock Rom like cm9 will not do anything but return an invalid mmi error. I should know my note is now permanently locked to att after 5 failed attempts and now Im waiting on a replacement to arrive. Meanwhile my note is now urooted and back to stock for about a week which is like chewing glass.

How would that happen? Someone would have to enter a different code in your phone, or you would have to flash stock rom with JTAG.
You call and ask

What true is it!!!

I just got another mega, this time I got a Att version. I spoke with a customer service rep. and got my unlocked code bcuz I purchased full price, I ask her about bloats ect ect. Ok this is what she told me, once I have unlocked my phone I have full control of my phone.. Hmmm really? I dont know if she knew what i was talking about.. then I ask about secure bootlock portion of the phone, she reply once your unlocked you could do what ever you want...:what:
I have the unlocked code, how would i unlock the darn thing? every phone is different ways to do it.
I want to know if its true or not that once unlocked we can do what ever including custom rom...

What I think you got from her was the network unlock code, all that does is allow you to move to another provider using the same phone.
So whats the difference between network unlock and phone unlock?

Network unlock is as above ^, the bootlock you mentioned in your first post is there to stop you removing their software, it's not something that you can change with a code. You need to remove the boot lock before you can replace the os with a custom one. Before you attempt to do anything like this I advise reading up on it, you don't want to brick another phone. The information is easily found by using google search.
Roger that..lol yeap I dont want to do that again..

No boot unlock yet so no custom recovery or custom ROMs.
I am talking about the I527 btw!

[Q] S3 - I9300XXUGML2 - GalaxSim Unlock not working, what to do to have data?

Hello,
I just installed I9300XXUGML2 on my i9300, the problem is that when trying to use GalaxSim unlock it says it is still not supported in this version.
I have the EVR version of the ROM which says it is Everywhere in UK and I am using Giffgaff. I have calls but still no internet even after configuring giffgaff APN options.
In 4.1.2 everything was working correctly, although I know that installing 4.1.2 from 4.3 could create issues.
What do you suggest?

Hi little confused if you are using Giffgaff sim these can only be used in unlocked phones.Why would you need GalaxySim unlock! If you have calls then your phone is unlocked?...

Indeed, that is what I do not understand. I have calls but not Internet and I was thinking it was because galaxsim unlock has not be runned.
I placed the APN giffgaff settings in several ways but nothing seems working. I have the H+ symbol on top but just not having internet....
I really dont know what to do.
Galaxy Sim doesn't work on new 4.3 update but you don't need it anyway you are unlocked if you weren't you would not be able to make calls.I would suggest trying another 4.3 stock rom.

Got it now... Sometimes the most obvious is not evident. I just changed how I paid giffgaff some weeks ago and it did not activate for this month, so I just paid and everything is OK now, thanks for your help.
