Abstract: The present invention provides a virtual subscriber identity module (vSIM) for network connection. The vSIM includes a memory and at least one processor. The memory is configured to store a remote SIM (rSIM) implemented as a software card. The at least one processor is coupled to the memory and configured to: register to a first network and download a vSIM profile from a vSIM server via the rSIM; and complete a registration to a second network using the vSIM profile for activating a vSIM service to connect to the second network. The present invention further provides an apparatus including the vSIM, a vSIM server for communicating with the apparatus, and a method performed by the apparatus.

Abstract: The present invention provides a vSIM module for a portable apparatus. The portable apparatus at least includes a slot. The vSIM module comprises a radio frequency chip, a baseband processor, a memory, an application processor, and a connector. The radio frequency chip is couple to an antenna. The baseband processor is coupled to the radio frequency chip. The memory is configured to store a vSIM connectivity management program. The application processor is coupled to the memory for executing the vSIM connectivity management program. The connector is configured to connect with the slot of the portable apparatus. When the vSIM connectivity management program is executed by the application processor, a vSIM service is activated.
