Abstract
A customer premise equipment (CPE) includes a control circuit, a storage device, and a wireless communication circuit. The storage device stores a virtual subscriber identity module (SIM). When the control circuit enables virtual SIM functionality on the CPE, the wireless communication circuit establishes a wireless communication link with a cellular telephone network via the virtual SIM.
Claims16
An electronic device comprising:
- a storage device, arranged to store a virtual subscriber identity module (SIM);
- a wireless communication circuit, arranged to establish a first wireless communication link with another electronic device that has a physical SIM installed therein, and obtain a physical ID of the physical SIM from said other electronic device via the first wireless communication link;
- and
- a control circuit, arranged to configure the virtual SIM according to the physical ID of the physical SIM of said other electronic device;
- wherein the wireless communication circuit is further arranged to establish a second wireless communication link with a cellular telephone network via the virtual SIM configured according to the physical ID of the physical SIM of said other electronic device, and to receive a voice call for the physical SIM of said other electronic device via the second wireless communication link from the cellular telephone network;
- wherein when the wireless communication circuit receives the voice call for the physical SIM of said other electronic device, the control circuit is further arranged to relay the voice call to said other electronic device.
