Set the phone to request the PIN code each time the phone is switched on. See Security on page 71. • The PIN2 code may be supplied with the SIM card and is required for some functions. • The module PIN is required to access the information in the security module. See Security module on page 105. The module PIN is supplied with the SIM card if the SIM card has a security module in it. • The signing PIN is required for the digital signature. See Digital signature on page 106. The signing PIN is supplied with the SIM card if the SIM card has a security module in it. If you enter an incorrect PIN code three times in succession, the phone may display PIN blocked or PIN code blocked and ask you to enter the PUK code.
