The described embodiments regard methods and apparatus for configuring a device that includes multiple subscriber identity modules (SIMs) and/or electronic SIMs (eSIMs) to support switching among active SIMs/eSIMs and standby SIMs/eSIMs via a software controlled hardware multiplexer. A wireless processor of a multi-SIM/eSIM wireless device includes a limited number of physical standardized interfaces, each interface supporting communication for a SIM/eSIM, and connects to multiple SIMs/eSIMs via a software controlled multiplexer. An applications processor of the multi-SIM/eSIM wireless device controls switching the interfaces between different SIMs/eSIMs. Software states of the SIMs/eSIMs are cached to allow rapid switching of SIMs/eSIMs between active and standby states. Interfaces of the SIMs/eSIMs continue to receive power in both the active and standby states, and interfaces are properly latched when switching to the standby state to allow rapid restoration when returning to the active state.
A method to manage configuration of multiple subscriber identity modules (SIMs) and/or electronic SIMs (eSIMs) of a multi-SIM/eSIM wireless device, the method comprising:
One or more processors of a wireless device comprising multiple subscriber identity modules (SIMs) and/or electronic SIMs (eSIMs), the one or more processor configured to:
A non-transitory computer-readable medium storing instructions for configuring one or more processors to manage configuration of multiple subscriber identity modules (SIMs) and/or electronic SIMs (eSIMs) of a multi-SIM/eSIM wireless device, the instructions comprising:
