1. A communications method, performed by a communications apparatus, wherein the communications apparatus supports a first subscriber identity module card and a second subscriber identity module card, and the method comprises:
determining that the first subscriber identity module card is in a connected state and the second subscriber identity module card is to enter a connected state from a non-connected state; and
in response to the determination, sending first information to a first device through the first subscriber identity module card, wherein the first information indicates a condition in which sending a paging message for the first subscriber identity module card to the communications apparatus is allowed by indicating at least one of the following:
information about a service that allows the first device to send the paging message for the first subscriber identity module card to the communications apparatus; or
information about a protocol data unit session that allows the first device to send the paging message for the first subscriber identity module card to the communications apparatus.
