Abstract: Apparatus and methods to support access to services of multiple wireless networks by a single-radio, multiple subscriber identity module (SIM)/electronic SIM (eSIM) wireless device are disclosed. To send or receive voice communications for multiple SIMs/eSIMs, when an active voice connection for a first SIM/eSIM uses wireless circuitry to connect to a first cellular wireless network via a first radio access network, the single-radio, multi-SIM/eSIM wireless device uses alternative data transports, such as via a wireless local area network (WLAN) or by tunneling through the first radio access network of the first cellular wireless network to connect to services of additional cellular wireless networks associated with the multiple SIMs/eSIMs.

Abstract: A device providing inter-device call continuity facilitated by a wireless audio output device may include a processor configured to initiate, over a peer-to-peer connection with a second device, a communication session between the second device and a third device. The processor may be further configured to establish, over the peer-to-peer connection with the second device, an audio link corresponding to the communication session. The processor may be further configured to determine, based at least in part on the audio link, that a connection quality of the peer-to-peer connection satisfies a connection degradation condition. The processor may be further configured to request, over a wide area network connection, for the communication session with the third device to be handed-off from the second device to the first device, and to establish, over the wide area network connection, the communication session with the third device.
