Hi, I Just got a Samsung SGH-x426 from a co-worker. Its an AT&T phone yet I have T-Mobile as my carrier. I cant seem to find any complete information on how to unlock this thing. I've been able to reach some sort of tool menu but I have no idea what the options do. I think I might be on the right path, but I'm stuck here. Anybody have any ideas or info for another method for unlocking?
Any help would be great. Thanks.
Just select option number 7.
When the phone reboots that is all you need.
If you find this post helpful please help others like yourself..

Unlocking:
If you have Rev 1.5 (x426) or earlier and most older models
Use the *#9998*3323# Trick (look for it on the forum)
The *#1111*WHATEVER# code will NOT work
If you have Rev 1.6 (x426) or later and most newer models
You MUST use unlocking software. Codes WILL lock your phone FOREVER
Locked: Return for Servicing
There is only 1 working solution, you must flash a copy of the firmware that is not in the locked status. (Most) Unlocking programs will NOT disable this issue, and your service provider cannot give you a code
If you do not plan to use your phone with another service provider, there is no real point to unlocking your phone other than to sell it. If you don't need to unlock it, don't take the risk of disabling the phone altogether
The *#9998*3323# Method:
1. If you have changed your phone password, change your password back to the default 8 zeros (00000000).
2. Put a SIM card that is from a network other than the one your phone is locked to
3. When Incorrect SIM error comes up, type *#9998*3323#.
4. White screen will appear with an exit option. Press the right softkey.
5. From the menu that appears, select the Malloc Fail option. This will reboot the phone and the normal service screens will appear.
6. Type *0141# and then press the green call key. "Personalization" or "Personalized" will appear.
7. Turn off your phone and put the original SIM back in.
8. Turn on your phone. You will receive a prompt to enter a password.
9. Type 8 zeros (00000000)
10. Completed. You have now unlocked your phone.
As for your pin problem wube, have you tried entering the PIN, because if you do so, it will let you back into the phone. If you don't I suggest you call your service provider for help or return the phone to whomever has the pin...

Hi,
Thanks for the info. I have the same problem : ATT phone which I need to use on a CIngular plan.
I am afraid to try the *#9998*3323# since I don't know which rev I have. How can I check? You mentioned that rev 1.6 or newer will need unlocking software.
Thanks!

There is no need to unlock for att on a cingular plan. Att and cingular phones both work on each other's towers due to the merger.

hi, i just registered in this forum and i liked it very much....
unfortunately, i already have a question.
My question is I have a Samsung SGH-426 and i dont know the "rev" number.....since its kind of new ...i think i can't just unblock it by putting in the codes so......where can i find the "unblocking software" so i can unblock this phone? how much? does the software only work for this phone?
Thank you, i would appreciate someone answering me.....thanks
