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.

Certain aspects of the present disclosure relate to methods and apparatuses for handling malicious attacks. In one aspect, the methods and apparatuses are configured to identify packets received from a malicious source based at least in part on packets received by a wireless device that change a state of the wireless device from a dormant state to a connected state, selectively disconnect the wireless device from a packet data network (PDN) by releasing a first Internet Protocol (IP) address used to connect the wireless device to the PDN when a number of packets identified as received from the malicious source reaches a threshold number within a monitoring period, and reconnect the wireless device to the PDN using a second IP address that is different from the first IP address. In another aspect, a connection to an IP Multimedia Subsystem (IMS) PDN is maintained after the PDN is disconnected.
