Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that it is a multi-subscriber identity module (SIM) device that supports communications with at least a first subscription corresponding to a first SIM and a second subscription corresponding to a second SIM, where the communications are transmitted or received via a single transceiver of the UE. Accordingly, the UE may simultaneously perform packet-based voice traffic using the first subscription and data communications using the second subscription, where the data communications occur during one or more durations of time in which the packet-based voice traffic is absent. For example, the UE may transmit or receive messages using the first subscription and then transmit or receive messages using the second subscription by tuning the single transceiver away from the communications for the first subscription when the packet-based voice traffic is absent.
