Abstract

A method for information transmission is provided, which is applicable to a terminal and includes sending indication information that the terminal has multiple SIMS to a base station in a process of establishing a radio resource control (RRC) connection. Using the RRC signaling to carry request content indication information can improve the utilization efficiency of the RRC signaling, reduce the interaction complexity caused by the newly added signaling and reduce the development workload.
