A network usage manager in an operating system executing on a mobile device is configured to enable selection among different cellular data connections by application ("app") or by app class so that end users can tailor cellular network allocation, app performance, and costs to meet their specific needs while mobile operators can improve network utilization and provide more comprehensive data plan offerings. The network usage manager applies app usage policies to select among different cellular data connections which may be supported on the mobile device using single or multiple SIM/UICC (Subscriber Identity Module/Universal Integrated Circuit Card) cards. The app usage policies can be set for a given app or class of app on the mobile device so that, for example, apps that implement background synchronization processes can use typically less expensive, lower bandwidth connections while typically more expensive, higher bandwidth connections are selected for data intensive apps. |
