or If you enter wrong password for more then 5 times,it ll ask you to enter the puk number....now call your customer care and
get the puk number...enter the puk number in the space given for password....thats it...problem is fixed
If you had locked your mobile then update the formware all saved passwords will be deleted

sir the deafault code is 0000 or 1234

If its the phone lock code and you have forgotten it, only Sony Ericsson will be able to unlock the phones lock code. Have you tried the default code which is usually either '00000' or '00000000'? If you have changed it from original default, unfortunatley there is no master code available! It has to done by manufacturer.
If its your SIM pin that is unknown then make sure you have your mobile number and call your network provider for a PUK code. Once you have this enter any code and after 3 attempts it will lock sim and request PUK code. Enter this and it will prompt you to set new pin, and repeat to confirm. Done.

Hello,
there is no other way to crack this code with computer with your mobile data cable. a software can crack this code so you go to nearest mobile reapiring shop and tell him the problem.. i hope this is the final solution. don't try to give it wrong code.
thanks

u have to take it to and authorised sony ericsson service centre. they are the only people that can tell you the code. a small fee will be involved

when it asked for PUK code if you enter correct the phone will work., if its incorrect you have to call your service provider and ask the PUk code for you phone number, they will help you in this

Keep entering any pin and when the phone asks for the PUK number enter it to reset it. The PUK (Personal Unlocking Key) is on the plastic card where your sim was attached.

Hi,

The phone lock code has probably been changed by the previous owner. You should contact him and ask him for the code.
