Dual SIM Dual Standby (DSDS) wireless devices are configured with a primary subscriber identity module (SIM) card providing both voice and data connections on a primary network and a secondary SIM card for providing data-only access on a secondary network. The utilization of wireless network resources by a DSDS wireless device can be enhanced by accounting for congestion on each of the associated networks and data usage of the device to determine whether a switch between networks would be beneficial for device performance.
