Zusammenfassung:	Systems and methods use the capabilities of multiple SIMs to prevent calls from being dropped on a multi-SIM wireless device. In the various embodiments, network conditions may be monitored for signal quality during an active call. When signal quality on the network deteriorates, the multi-SIM wireless device may switch the active call to a network associated with a different SIM that provides better service. To enable the switch, the multi-SIM wireless device may setup a conference call with the called party and the different SIM. In the various embodiments, the multi-SIM wireless devices may be a dual-SIM dual active (DSDA) wireless device.
