An information reporting method, performed by a terminal device, wherein the terminal device comprises multiple communication modules, and the method comprises: reporting first information to a network device if a first preset condition is satisfied, wherein the first preset condition represents that the multiple communication modules have a communication conflict, and the first information represents assistance information for assisting solving the communication conflict, wherein the multiple communication modules comprise multiple subscriber identity modules, SIMs; wherein the first information comprises at least one of the following: which communication modules of the terminal device are or a current communication module is in an unreachable state; which services of the current communication module are in the unreachable state or services of communication modules of the terminal device that are in the unreachable state; which objects of the current communication module are in the unreachable state or objects of communication modules of the terminal device that are in the unreachable state; which communication modules of the terminal device are or the current communication module is in a reachable state; which services of the current communication module are in the reachable state or services of communication modules of the terminal device that are in the reachable state; and which objects of the current communication module are in the reachable state or objects of communication modules of the terminal device that are in the reachable state. reporting first information to a network device if a first preset condition is satisfied, wherein the first preset condition represents that the multiple communication modules have a communication conflict, and the first information represents assistance information for assisting solving the communication conflict, wherein the multiple communication modules comprise multiple subscriber identity modules, SIMs; wherein the first information comprises at least one of the following: which communication modules of the terminal device are or a current communication module is in an unreachable state; which services of the current communication module are in the unreachable state or services of communication modules of the terminal device that are in the unreachable state; which objects of the current communication module are in the unreachable state or objects of communication modules of the terminal device that are in the unreachable state; which communication modules of the terminal device are or the current communication module is in a reachable state; which services of the current communication module are in the reachable state or services of communication modules of the terminal device that are in the reachable state; and which objects of the current communication module are in the reachable state or objects of communication modules of the terminal device that are in the reachable state. which communication modules of the terminal device are or a current communication module is in an unreachable state; which services of the current communication module are in the unreachable state or services of communication modules of the terminal device that are in the unreachable state; which objects of the current communication module are in the unreachable state or objects of communication modules of the terminal device that are in the unreachable state; which communication modules of the terminal device are or the current communication module is in a reachable state; which services of the current communication module are in the reachable state or services of communication modules of the terminal device that are in the reachable state; and which objects of the current communication module are in the reachable state or objects of communication modules of the terminal device that are in the reachable state.
