Difficulty: MediumMobile Device Synchronization and Cloud Integration

A remote employee reports that their smartphone automatically synchronizes corporate calendar items and contacts while connected to a Wi-Fi network, but synchronization halts completely whenever the device operates on a cellular data connection. The employee confirms that cellular data is turned on and web browsing works normally. Which of the following configuration settings should the technician inspect on the mobile device to resolve this issue?

  1. Cellular data usage and background data restriction settings for the corporate accountAnswer
  2. B
    The account incoming mail server configuration to switch the protocol from IMAP to POP3
  3. C
    The enterprise Mobile Device Management (MDM) portal to execute a full factory wipe of the handset
  4. D
    The carrier provisioning profile to update the device's International Mobile Equipment Identity (IMEI)

Answer

Inspect cellular data usage and background data restriction settings for the corporate account on the smartphone.
The correct solution is to check cellular data usage and background data permissions for the corporate account. Mobile operating systems include settings that disable background data usage or automatic synchronization when connected to cellular networks to prevent unexpected data charges. Since web browsing functions normally over cellular data, the cellular radio and SIM card are working properly, and the issue is restricted to background account sync permissions.

Step-by-Step Solution

1
Analyze the reported symptom and network behavior.
The device synchronizes over Wi-Fi and general cellular internet browsing works, ruling out total cellular hardware or SIM activation failures.
Synchronization issues limited specifically to cellular connections point to OS-level cellular data saver or background sync restrictions.
2
Identify the relevant mobile operating system setting.
Checking the background data permissions for the corporate synchronization account reveals restricted cellular usage.
Enabling background data access over cellular networks permits automatic sync operations regardless of connection type.
