Abstract
Disclosed in the present invention are a method and system for selecting VOLTE according to an SIM card by a mobile terminal, and the mobile terminal. The method comprises: establishing a relationship table between a PLMN of a preset SIM card and ID values; performing a dynamic search by means of the PLMN of an SIM card; querying, in the relationship table, to determine whether the PLMN exists and whether the PLMN needs to be updated; when the PLMN exists and needs to be updated, obtaining an ID number of a current SIM card according to the relationship table; and when the PLMN does not exist, obtaining a default ID value; and obtaining a related configuration parameter according to the obtained ID.
