Step 3 To access any resources (data or commands) on the SIM, the EAP-SIM supplicant must provide a valid
PIN to the SIM card, which must match the PIN stored on the SIM. Select one of the following options
to specify how the EAP-SIM supplicant should handle the SIM card’s PIN:
• Ask for my PIN once after I turn my computer on (recommended)—The software does not
permanently store the PIN. It prompts you for the PIN once, on the first authentication of every
session, where a session is defined as the time between power-up and shutdown or reboot.
• Ask for my PIN every time the network asks for authentication—The software never stores the
PIN; it prompts you for the PIN every time an EAP-SIM authentication is performed. This option is
not recommended if your client will be roaming between access points or if session timeouts are
implemented (such as for accounting and security purposes).
