1. A network configuration method of a multi-card mobile terminal applied to the multi-card mobile terminal, comprising:
in response to a first network access state of a subscriber identity module (SIM) card of the multi-card mobile terminal being a connected state and another SIM card of the multi-card mobile terminal requesting to access a target network, generating access request information of the another SIM card and transmitting the access request information to a target network-side device, the access request information comprising a capacity limitation indication, the capacity limitation indication being configured to indicate that a current terminal wireless capacity of the multi-card mobile terminal is limited; wherein the capacity limitation indication is a preset RA prefix or a preset RA occasion in radio resource control (RRC) signaling, wherein on condition that the capacity limitation indication is the preset RA prefix, the network configuration information is second signaling and fourth signaling in a 4-step RA procedure; and
receiving network configuration information corresponding to the access request information transmitted by the target network-side device; and
configuring the multi-card mobile terminal according to the network configuration information.
