Configure telecom expense management

With telecom expense management (TEM) you monitor cellular data usage of individual devices.


Telecom expense management is not available for:

  • Devices without SIM card and cellular data plan
  • Android Enterprise work profile devices
  • Apple User Enrollment devices
  • Macs
  • Windows computers
  • Chrome devices

Configure telecom expense management

To configure telecom expense management for specific devices:

  1. On the menu sidebar, click Devices.
  2. On the Devices page, select the devices for which you want to configure telecom expense management.

    Only select devices with the same cellular data plan.

  3. Click Actions > Configure telecom expense management.

  4. Configure the following settings:

    • Turn on monitoring: If selected, monitoring cellular data usage is turned on for the selected devices.
    • Data volume of plan: The data volume in MB of your cellular data plan.
    • Alert threshold: A data volume threshold in MB.

      When a device exceeds this value, Sophos Mobile creates an event, which you can see on the device’s details page, and an alert.

    • Usage cycle reset date: A value between 1 and 31 to specify the day of the month when the data usage value is reset.

      If a month has fewer days than the value entered, the data usage value is reset on the last day of the month.

  5. Click Save to apply the settings to the selected devices.

Cellular data usage is reported by a device every time it syncs with Sophos Mobile.

View data usage

To view the current data usage of a device, open the device’s Show device page and then click Actions > Configure telecom expense management.

The reported data usage might deviate from the values charged by your telecom provider. Data traffic caused by installed apps is reported, but not system updates, system app updates, or similar.

For iOS, data usage is not reported when the Sophos Mobile Control app is closed, e.g. when the user has not started the app after restarting the device.


Use the Cellular data usage report to view the data usage for all devices that have telecom expense management turned on. See Reports.

Reset data usage

The data usage value is reset at these times:

  • Regularly every month at the end of the day you configured.
  • When you turn off telecom expense management for the device.
  • When the device is unenrolled from Sophos Mobile.
