Unlocking the S3 - Galaxy S III Q&A, Help & Troubleshooting

I have an S3 I9300 on OmegaROM V42 and 4.1.2 which is factory locked to my network.
I would like to unlock the phone so it will take any SIM card.
What is the easiest/quickest way to achieve that?
A way that hopefully I do not need to restore my data.

Insert your new SIM card and turn the phone on, when prompted enter the sim unlock code you obtained from your current network.
There is currently no 'free' way to unlock.

If your phone is the i9300 it's already unlocked.

Weird answer, network lock is present on all i9300 phones on bought via a network contract.

Yes it is definitely locked but the operator will not unlock until contract ends.
What about something like the GalaxSIM app from the play store?
Will that do it?

No, it won't.

best option try a third party unlock website
or also certain users on ebay offer a fast cheap unlock service for many networks

Instead of starting a new thread I'll ask here. Does anybody know of a good third party unlocking site? I'm trying to unlock a phone for my friend, but I'm not sure where it's from... possibly it's an international version? Any way to find out what it's locked to?

Why not request the unlock code from your network operator? It may be free.

It's only free (on some networks) if you've been with them on the same line for a long time.

how to re-lock to the network?

Hi, I bought the phone and it is locked onto the network,so I bought the codes from ebay, and I don't know if the warranty is still valid because it is unlocked. So, is there a simple way to lock it to the network again? Or, there is no need to re-lock it because they can't see it its unlocked because I used a code. Thanks
Network lock has nothing to do with warranty .

Apparently in my country it does. They check if the phone is locked and then they try to repair it ...

You can't relock it unless you got a backup of the EFS folder.
What country are you in? Most providers may try funny business but that does not mean it actually would be legal for them to do

If I root Sony Xperia U will it unlock phone to all networks?

Hi, I'm in the UK and looking at buying the xperia u for my sister. However it is locked on either o2 or Vodafone, depending on where I buy it from.
My question is how do I unlock the phone to make it sim free, I want to put a t mobile sim in there.
Do I root the phone to make it sim free? Or is there some other method.
Thanks for any help.

Buy it from phones4u and it'll be unlocked. No rooting doesn't unlock
Also depending on what she wants it for the 'U' isn't that great really. If you're buying it out right then get an S off eBay. They go for only around 120-150 area

O2 will unlock it for free if you have a contract with them (or get someone with a contract to do it).
CPW stock is also unlocked.
You have to install a Custom Rom

are you sure this will work?
Installing a custom rom or rooting the device will not make your phon sim free. If you want a network unlocked phone get it factory unlocked otherwis you will end paying for an unlocking service.

Thank you for your cooperation.
Unlock codes can be purchased online for just a few bucks. Idk if I'm allowed to list sites here or not but here is the one I use the most for unlocking phones Cellunlocker.net I've unlock alot of phones with their service for just a few bucks. I think the last time I unlocked a Atrix 4G it cost about $15

unlock your phone and install an international rom.

I'm assuming by "unlock" you mean unlocking the bootloader and then flash a custom rom. This wouldn't gsm unlock a phone to a different carrier.

when i unlocked mine it now shows all networks when i have no sim card installed. havent tried another carriers sim card in it to see if it works sorry if i was incorrect.
I'm on the same boat, I bought an Atrix 4g on amazon which was supposed to be gsm unlocked, but the only thing it had unlocked was the bootloader. I couldn't return it since I'm from Venezuela so I have to look for a way to unlock it.
I went to a store where they do this kind of stuff, the guy had some "zunzun" software to do it but it said something about the firmware being incompatible (android 2.3.6 4.5.141), I guess if downgrading doesn't work I'll end up buying an unlock code on one of those websites. I preferred the other method because I can pay with the local coin instead of buying expensive dollars...
@rdz420, please update if you manage to unlock it.
I've unlocked my Atrix 4G here, they are legit and it's cheap.

Take in mind that some AT&T phones can't be unlocked via code.. that's what they told me. (Mine is UK Orange, so I could unlock it :good
hey guys
I did not unlock the phone yet, but I spent a few shops that do unlocking here in Brazil, the majority says that the cel need to try to generate the code, but how they are generating the code? will be a trusted site?
Besides this method gave some research on kernel change, it seems that with the change of kernel + rom the phone would be unlocked with the network. right? anyone have any positive experience in the area?
thanks
Bootloader unlock = you can flash roms
sim unlock = you can use on other networks
One does not rely on the other, and i haven't seen any issues with one affecting the other

As @palmbeach05 said, both are independant. Bootloader unlock (thus installing new roms and kernels) doesn't unlock for any carrier and sim unlock by itself won't allow you to install new roms and kernels.
