SIM Card Security
To protect a SIM card from others using it for phone calls or cellular data, a SIM PIN
can be used. When a SIM PIN is used, the SIM card will automatically lock upon an
ICX35-HWC reboot. The PIN protection enablement, PIN (Personal identification
number), and PUK (PIN unlock key) codes are saved on the SIM card. Replacing the
SIM card requires a reconfiguration of the SIM settings.
Most mobile devices offer SIM PIN protection. At startup, if the PIN security function
is active, the user must enter a 4 to 8 digit PIN to enable the ICX35-
HWC’s non-
emergency functions. You can save the PIN code in the configuration in an encrypted
format.
