SIM control policy

The SIM control policy allows you to configure a default group of settings that restrict SIM functionality or lock devices with unlisted SIM cards.

Each mobile device carrier has their own unique MCC and MNC pair. SIM cards that match the MCC and MNC pairs allowlisted using this policy can be used without restrictions. You can list a maximum of 50 MCC and MNC pairs.

For dual-SIM devices, restrictions only apply to the unlisted SIM card. Up to a maximum of 10 SIM control policies can be set.

To update this policy for select devices, see Enable and disable SIM control.

The available sub-settings are: Mobile Number Lock — Allows device users to enable or disable IMSI policies regardless of whether MCC/MNC information is provided. Turn on network registration verification — Validates that a blocked SIM card is not being misused by verifying that the connected network matches the allowlisted networks (via MCC/MNC). Block incoming calls when device is locked — You can add phone numbers that are allowed to call. Allow PIN Code unlock — Allows the SIM locked device to be unlocked using a PIN.
