[Q] SIM Unlock Samsung Galaxy S2 - AT&T Samsung Galaxy S II SGH-I777

Not finding reliable infor on this anywhere. I need to do a SIM unlock on my S2. AT$T says "the manufacturer provides this code", and the manufacturer says that "AT$T provide this code". I say, I'll get what I need from XDA, the only reliable source of info. How do I SIM unlock this damn phone?

moderators will tell you to do more searching next time. This was easy to find.

Hi, i want to sim unlock my phone, but if i do that i am losing Warranty, so is there some app to lock my phone again for the same mobile operator (in my case mts telekom Serbia). thanks

The app mentioned in that tutorial backs it all up for later restore if needed.

I believe if you're with them (AT&T) for more than 6 months, you can ask them for the unlock code (say, for travelling aboard)

Please delete this thread. The unlock thread was on the first Page ffs

You can get the Unlock code from service provider.But service provider ask to wait for some days they will not give the Unlock code very soon.You can better get the unlock code from Mobileunlocksolutions.com and unlock it from network lock.After Unlock it use with any GSM Network Sim card.

Or you can actually take 2 minutes of your time and search and get it all done with an app that's right under your nose in the market.

It amazes me some people still don't know about this. But I guess its not the norm? I know I had to call AT&T to get my Atrix unlocked free.

Well this phone is a bit different then most (like our Recovery being part of the actual kernel) so perhaps other phones don't have a simple software unlock and you HAVE to get the code from ATT. I know my old Moto Backflip didn't have a software option.

Wow $35! I got my unlock code from cellunlocker.net for only $8, took 3hrs for them to send the code.
Edit: just checked... They charge $33 for bell note. don't know why Rogers is so much cheaper to unlock.

Actually since Rogers owns Fido, you can interchange the sim's from Rogers to Fido and vise versa with a locked device.
They made that change a few years ago.
gemor said:
same here, used cellunlocker.net for unlocking Rogers locked Galaxy Note i717R... $8, code within 6 hours (got it in the morning)... didn't have Bell sim card so I could not open network unlock input even with #7465625*638*#... finally went to a local mall and asked a guy at mobile stand to borrow Bell sim card... no charge... entered code... "Network Unlock Successful"...
however I am with FIDO and when I type *#7465625# to check if phone is in fact unlocked I get to black personalization screen and it force-closes in couple of seconds... no unlock status information provided... just crash... Could that be connected to the fact that Galaxy Note is network unlocked but it not rooted?

Can I Unlock Without an AT&T Account???

I'm thinking of buying a used one of these off craigslist ... but I'm on tmobile and I'm worried that I won't be able to unlock it without having an AT&T account first .... Can I unlock one of these without having an AT&T account? Most steps I've read talk about downloading an unlocker program from the market ... but without an AT&T sim card in the phone I don't think I'll be able to access the market ...
What do you all think?
You don't have to have cell network to connect to a wifi and log into market. You will need to root it also before those apps will work. Just fyi though. You will NOT get 3g/4g on T-Mobile

3g/4g only involve data speeds, right? I have wifi at home and at work and do not use a data plan ... So I can root and then unlock on my home wifi without any AT&T account?
I see no reason you can't. I have done lots of phones that way.

Another way you can check is by putting another sim card in and if its locked it will tell you.

I dont have to use voodoo sim unlock because i bought mine full price from Samsung,unbranded but i would still like to be able to use dialer codes...

try installing the omega 12 rom, as it has sim unlocking built in
The *#7465625# does not work on the Galaxy S3 anymore. That was the case for me and for everyone reporting here. I was able to get the same screen ans figure out my S3 was locked by using the app "SGS Secret Codes", which is available on the Play Store.
Does anyone know a way of figuring out which particular network the device is locked to? I just bought an S3 which was supposed to be unclocked bu it is not, and to unlock it I need to know which carrier it is locked to.

Carrier unlock

Is there a way to carrier unlock the amaze without calling T-Mobile?
I called T-Mobile and they gave me the code but I put it in wrong and after one failed attempt you can't put it again.
What's weird though is that I went to mexico and inserted a foreign sim card and to my surprise my phone got service.

Hey Eduardo!
Well the best way (easiest) to unlock is to just call T-mobile and say that you're going to some foreign place like Brazil or Ecuador or something. If one rep refuses to unlock you just call again and repeat until someone gives you an unlock code lol. Just tell them you're going out of state and need an unlock code, they will give it to you 9/10 times anyway, so you shouldn't have much trouble.
The OTHER way is to do this. Right now it's in a gray area because of the stupid law banning unlocking (except by carrier), but the Amaze was released before the law came into play so I guess it avoids the law. Good luck!
http://forum.xda-developers.com/showthread.php?t=1659430
Also, if you entered the code wrong, it's fine! It will still work anyway. :good:

hi! I bought a Sprint Note 3 on Ebay. to make a long story short, phone is global. when dialing *#06#, it was giving me a MEID. it has a sim slot even tough it's with sprint witch is a cdma carrier. I called sprint and they give me a 6 digits code, telling me it's the unlock code. after a few research on google and messing around in the phone, I now get a IMEI number after dialing *#06#.
when dialing ##0011#, i see NETWORK: UNBLOCK. the phone work on the same frequncies as my carrier I'm trying to unlock the phone to. but I never found the key pad where to enter the unlock code to actually unlock the phone (supposed to restart the phone with the wrong sim card and a "please enter unlock code" prompt should appear, but not me). I used it to get in the data hidden menu (##3282#), and that it. my sim card does not work, and I'm out of options...
