Manage SIM Operations

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.

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
