[Q] Lost my official network unlock after resetting my phone - AT&T Samsung Galaxy S II SGH-I777

Hi
I had unlocked my ATT S2 using official code from ATT. However after resetting my phone recently my phone is locked again. I had saved that code which they sent me to unlock my phone. However that code doesn't work anymore. Any suggestions on what I should do?
thanks

I would suggest you call AT&T.

I called ATT and got a new unlock code from them. However his unlock code is not working. I will try to call them again tomorrow.

If possible take a corporate store location. If the next code doesn't work.

HELP!!! Can't unlock.

Phone will not produce unlock code. Tried terminal but Vibrant will not go pass /is -ad. I think I flashed too many roms?!?!
I think the updates patch the hole the unlock program exploits. So its possible that you did.

That's why the second I saw that it was possible to unlock the phone, I got the unlock codes. You don't have to use them right away, but you should get them in case you ever need them.
Try "samsung galaxy s unlocker". I dont know what your trying to unlock with. this ^ is a market app that requires no terminal commands
Produces the unlock code and saves it to sd

Just call carrier and ask to provide you with the unlock code.. tell them that you travel out of the country and don't want to pay to much on international calls.. might take a couple days but at least you will always have the unlock code.

I forgot about calling the carrier. Thanks alot for you guys help! I had already tried the app but it still did not produce a code and asked if I had a Samsung Galaxy S phone. Disappointing that I couldn't do it myself.

Sim Unlock?

hey guys is there anyway i can unlock the atrix without calling att or spending any money? for my s2, there was an app on the market that did everything. i thought that unlocking the boot loader would let me use another sim, so now i am unlocked and rooted on 2.3.4. but it did not work. Cant i just flash a rom that unlocks my sim, if so what rom?
THANKS
it's easy. Just go to AT&T support page & choose live agent. If you don't get anyone now just wait 5/6 minutes till anyone becomes free. When anyone start chatting with you simple tell your need. He'll ask your IMEI. Give it & he'll give you the unlock code instantly
Contacting AT&T is not an option. I do not have a account. Is there any other way I can do it without contacting AT&T or spending money? My phone has unlocked boot loader and is on rooted 2.3.4.

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.

Just to make sure I'm not missing something, your friend has an ATT phone and his account get's frozen when he tries to put in another ATT SIM or a SIM from a different carrier? If it freezes his account when putting in another ATT SIM in his ATT phone then I would recommend contacting ATT and explaining what is happening to them as that's a network operator error. If the phone freezes his account when putting in another SIM from a non ATT carrier then what you can do is ask ATT for a SIM unlock code or if you tell me what model your friends phone is there places online you can buy a SIM unlock code you can enter yourself on your friends phone. Let me know if you still have questions.

Unlocking the S3

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.
Sent from my GT-I9300 using Tapatalk
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?

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?
