Detailed Implementation Methods

[0035] To fully understand the purpose, features and effects of the present invention, the present invention will be described in detail below with reference to the following specific embodiments and accompanying drawings.

[0036] Please refer to Figure 1 The flowchart below illustrates a multi-SIM card reading method according to the present invention. The multi-SIM card reading method of the present invention can be roughly divided into four stages: 1. Determining whether the current device has a 4G card; 2. Determining whether the current 4G firmware is in dual-SIM mode; 3. Reading and comparing the Integrated Circuit Card Identifier (ICCID) of the currently configured SIM card; 4. Switching to another SIM card and reading and comparing another ICCID.

[0037] In practice, determining whether the current device has a 4G card can be divided into steps S10-S11. In step S10, the interface information of a modem module is obtained. In step S11, a first interface name of the modem module is set to a second interface name associated with LTE. Determining whether the current 4G firmware is in dual-SIM mode can be divided into steps S12. In step S12, the slot status of the modem module, which is associated with multiple SIM cards, is obtained. The process of reading and comparing the ICCID of the currently set SIM card can be divided into steps S13-S14. In step S13, based on the slot status of the modem module, the parameters corresponding to a first SIM card slot are obtained. In step S14, the readiness information of a first SIM card is obtained. Switching to another SIM card and reading and comparing another ICCID can be divided into steps S15-S17. In step S15, the parameters corresponding to the first SIM card slot are switched to the parameters corresponding to the second SIM card slot. In step S16, the successful switch is confirmed. In step S17, readiness information for a second SIM card is obtained. Specifically, all the above steps are performed automatically using a multi-SIM card reading method configured with a processor and programmed in C#.
