Method for providing a personal identification number to a subscriber identity module |
摘要 |
A method for automatically entering a SIM's PIN in case of a reset or other condition includes the steps of storing (206) in RAM the PIN after it has been verified (204). Whenever a reset condition occurs, the PIN that is cached in RAM (106) is automatically presented to the SIM (214). In order to make sure that the PIN stored in RAM (106) in not corrupted during a reset condition, the inverse (208) or other coded form of the PIN is also stored in RAM (106) as an additional check of the correctness of the stored PIN.
