1. An electronic device, comprising:
a first interface for accessing network resources over a first communications network; a second interface for accessing the network resources over a second communications network; and a processor configured to: responsive to a request to access the network resources, select one of the first interface and the second interface to test first based on a respective power state of each of the first interface and the second interface; test a service characteristic of the selected one of the first interface and the second interface and power on the other one of the first interface and the second interface, wherein the service characteristic of the selected one of the first interface and the second interface is tested concurrently with the other one of the first interface and the second interface powering on; test a service characteristic of the other one of the first interface and the second interface; and access the network resources with one of the first interface and the second interface based on the respective service characteristics of the first interface and the second interface, wherein the service characteristic of each of the first interface and the second interface is tested by performing a ping test a preset number of times and averaging the ping test results, and wherein the network resources are accessed based on respective billing rates associated with the first communications network and the second communications network.
