A wireless User Equipment (UE) to optimize network communications for a user application. A UE operating system receives a user permission for the user application to access network characteristics. The user application calls the operating system for the network characteristics, and the operating system obtains the network characteristics from wireless network circuitry in response to the user permission. The operating system transfers the network characteristics to the user application. The user application selects one of multiple wireless communication networks based on the network characteristics. The wireless network circuitry wirelessly exchanges user data for the user application with the selected wireless communication network.
