Enable and Disable SIM control

Knox Guard devices in any state except 'rejected' state can be controlled for their SIM operation individually, collectively, or in bulk. The solution provides features like locking a device when needed, applying usability restrictions for voice, text and data usage, and applying International roaming restrictions.

For information on setting SIM control default values, go to: Manage defaults.

NOTE - When an approved SIM is removed from a device a message displays indicating their device SIM cannot be detected or is from an unsupported service provider and requires replacement with an approved SIM.

NOTE - SIM control can be applied to a device in any status state, except devices in a rejected state.

    If the 'Lock device' checkbox is selected, 'Locked devices' messaging is shown. If voice calls, SMS/MMS/RCS, or data usage is disabled, 'Restricted actions notification' messaging is shown. This information is read-only; messaging must be edited within Policies.

    Refer to the MCC and MNC fields to assess if a default Mobility Country Code (MCC) and Mobile Network Code (MNC) has been applied to uniquely identify the selected device’s mobile network carrier for SIM control restriction exclusion. Each mobile device carrier has their own unique MCC and MNC pair. To revise the default MCC/MNC code assignment, go to: Manage defaults.
