Abstract: There is provided a user device including a transceiver, a processor, and a memory. The memory stores a device management application (DMA) arranged to disable at least one function of the user device in accordance with an operative device policy state of the user device, and a device policy schedule comprising a queue of device policy states each having an associated respective set of policy data. Responsive to receiving, from a remote system via the transceiver, first synchronisation data indicating a first device policy state in the queue of device policy states, the DMA is arranged to update the operative device policy state of the user device to the indicated first device policy state.
