Samsung S5230 forgot Sim Password

After you enter the password wrong 3 times, the phone will ask for a puk code, to get this puk code call your phone service provider, only the owner of the sim card will be able to obtain the code from the service provider. There is no way of getting the puk code since it is a random number generated by your network operator when the sim card made for you. if you enter the puk code wrong too many times you will have to get a new sim card as the sim card will kill itself when the code has been entered wrong 10 times.
