    If the user changed the code from the default the only way to get this corrected is to call the manufacturer for assistance. Unless it is a sim PIN or Subsidy Unlock Code your carrier will not know the user's personal security code.

    Well the standard cellphone codes are either 0000 or the last 4 digits of your phone number. Hope this helps. I hope you get the problem resolved.

    People generally don't change the code for that. If it isn't stolen then you should have no problem contacting customer service and they will help you unlock it.

    type in the last four digits of your phone number.
