Secure your SIM cards by using PINs to prevent
unauthorized use of the SIM cards. You can manage the cellular SIM
by enabling, disabling or unblocking the SIM PIN.
On
an inactive SIM, only PIN configuration can be saved. All other
SIM operations such as enable, disable, unblock or change PIN, are
not available.
Set the SIM PIN using the CLI toolkit commands toolkit
commands before a device is claimed. The ION device sends the configured
PIN to the controller.
Even before an ION device is
claimed, a superuser can configure the APN, SIM security, and upgrade
the firmware using CLI toolkit commands to
configure a specific APN to gain WAN connectivity or to unlock a
locked SIM from the provider to establish WAN connectivity.
Enable the SIM PIN
Enable the SIM PIN to lock the SIM card to
a modem so it can't be used until the correct code is entered to
access the cellular network. PIN verification is triggered after every
modem reset. You get three attempts to enable the SIM PIN.
A
yellow triangle adjacent to the lock icon indicates failed PIN verification.
A red lock indicates PIN validation failure after the third failed
attempt, after which the SIM is blocked. A PUK (Personal Unblocking
Key) from the provider is required to Unblock SIM PIN. A Device_Cellular_SIM_PUK_Needed alarm is raised when the
SIM is blocked after three failed attempts.
When the
active SIM is blocked, an automatic switchover to a secondary SIM,
if present, happens.
