  • Multiple Active Voice Calls on a Multi-SIM Multi-Active Device
    Publication number: 20160014578
    Abstract: Methods, devices, and systems of various embodiments enable the handling of simultaneous calls on a MSMA device having at least a first subscriber identification module (SIM) associated with a first transceiver and a second SIM associated with a second transceiver. A processor may establish a first SIM call using the first transceiver. The processor may also establish a second SIM call using the second transceiver while maintaining the first SIM call active. The first SIM call may be maintained active by the processor connecting the first transceiver to a first input/output device and the second SIM call may be maintained active by the processor connecting the second transceiver to a second input/output device.
