For example, the power management unit 114 may check the data available time and transmit a push notification message to the user terminals 200 and 210 subscribed to the service. For example, the power management unit 114 may inform a percentage of the remaining amount of data available time (70% remaining, 50% remaining, 30% remaining, 5% remaining, etc.).

In addition, the power management unit 114 controls the power of the telematics unit 110 to be shut down when the data available time is exceeded. In addition, the power management unit 114 may provide a notification message indicating that the remaining service time is exhausted to the user terminals 200 and 210.
