Abstract
Devices, systems, and methods for handling simultaneous calls on a multi-subscriber identification module (SIM) multi-active (MSMA) device having at least a first SIM associated with a first transceiver and a second SIM associated with a second transceiver. A processor of the MSMA device may establish a first SIM call using the first transceiver and a second SIM call using the second transceiver while the first SIM call is active. The processor may also establish a direct wireless link to a second mobile communication device using a third transceiver. The processor may maintain both the first and second SIM calls active simultaneously by handling the first SIM call using an input/output device of the MSMA device and relaying the second SIM call to the second communication device via the direct wireless link.
