1. A communication method for multi-card user equipment (UE), comprising:
registering with a first operator network by the multi-card UE using a first Universal Subscriber Identity Module (USIM);
in response to receiving a request for obtaining information about a USIM belonging to a non-first operator network used by the multi-card UE, feeding back, by the multi-card UE, the information about the USIM belonging to the non-first operator network to the first operator network, wherein the request is initiated by the first operator network; and
receiving, by the multi-card UE, configuration information for the non-first operator network sent by the first operator network, wherein the configuration information is configured by the first operator network for the multi-card UE based on the information about the USIM belonging to the non-first operator network; and listening for, by the multi-card UE, the non-first operator network according to the received configuration information; wherein
the configuration information for the non-first operator network comprises at least one of following:
time information of listening for paging belonging to the non-first operator network, measurement time information of listening for the USIM belonging to the non-first operator network, or a reading time of listening for a system message belonging to the non-first operator network.
