Method and apparatus for switching in-vehicle service by using external SIM card

A method for switching an in-vehicle service by using an external SIM card, comprising:

• detecting whether a valid SIM card is inserted into an external SIM card slot of a TBox;
• and
• when the TBox detects that a valid external SIM card is inserted into the external SIM card slot, switching, by the TBox, to a network to which the external SIM card belongs, wherein:
• there are a plurality of external SIM card slots, when the TBox detects that a plurality of valid external SIM cards are inserted into the plurality of external SIM card slots, the TBox switches to a network to which an external SIM card belongs based on a user selection or a preset priority order, wherein the preset priority order is at least based on following condition:
• time, geographic region, or when performing a specified in-vehicle service;
• and
• the TBox is configured to give a plurality of user messages of prompting SIM card switching on a user interface, wherein the plurality of user messages comprises:
• a first message indicating that SIM card switching is about to be performed;
• and
• a second message indicating that the SIM card switching is successful;
• and wherein the TBox switching to the network to which the external SIM card belongs further comprises:
• changing, by the TBox, an in-vehicle service parameter, logging in to a server corresponding to the external SIM card, and obtaining content of an in-vehicle service.

A non-transitory computer storage medium storing one or more programs, wherein the one or more programs comprise an instruction, wherein the instruction is used to detect whether a valid SIM card is inserted into an external SIM card slot of a TBox, and when the TBox detects that a valid external SIM card is inserted into the external SIM card slot, the TBox switches to a network to which the external SIM card belongs, wherein:

• there are a plurality of external SIM card slots, when the TBox detects that a plurality of valid external SIM cards are inserted into the plurality of external SIM card slots, the TBox switches to a network to which an external SIM card belongs based on a user selection or a preset priority order, the preset priority order is at least based on following condition:
• time, geographic region, or when performing a specified in-vehicle service;
• and
• the TBox is configured to give a plurality of user messages of prompting SIM card switching on a user interface, wherein the plurality of user messages comprises:
• a first message indicating that SIM card switching is about to be performed;
• and
• a second message indicating that the SIM card switching is successful;
• and, wherein the TBox switching to the network to which the external SIM card belongs further comprises:
• changing, by the TBox, an in-vehicle service parameter, logging in to a server corresponding to the external SIM card, and obtaining content of an in-vehicle service.
