A user's smartphone data usage is well above average. The user suspects an installed application is transmitting data in the background. The user would like to be alerted when an application attempts

Operating system updates are crucial for security and performance but do not inherently provide real-time alerts for individual application data transmission attempts.

Remote wipe is a security feature used to erase all data from a lost or stolen device; it does not monitor or alert about application data usage on an active device.

Antivirus software primarily detects and removes malware; while some antivirus apps include network monitoring, a dedicated firewall is specifically designed for granular control and alerting on network connections for all applications, which is the user's explicit request.

A firewall, when installed on a smartphone, monitors and controls incoming and outgoing network traffic. It can be configured to alert the user whenever an application attempts to connect to the internet, allowing the user to identify which apps are using data and block unauthorized or excessive communications, directly addressing the concern about background data transmission.
