A method for network search performed by a terminal in a dual-Subscriber Identity Module, SIM-card mode, the method comprising: acquiring a network search instruction for a secondary card and, responsive to the network search instruction, detecting whether a master card is performing data interaction; characterized in that the method further comprises: responsive to detecting that the master card is performing the data interaction, starting foreground Public Land Mobile Net, PLMN, search for the secondary card; responsive to detecting that the master card is not performing the data interaction, starting background PLMN search for the secondary card, when the background PLMN search fails, starting the foreground PLMN search for the secondary card; and displaying operator network information found for the secondary card by the foreground PLMN search or displaying operator network information found for the secondary card by the background PLMN search; wherein when the foreground PLMN search is started, use of a network by the master card is suspended, and wherein a priority of the background PLMN search is lower than a priority for performing the data interaction by the master card, and wherein the foreground PLMN search refers to full-band search and the background PLMN search refers to partial-band search. acquiring a network search instruction for a secondary card and, responsive to the network search instruction, detecting whether a master card is performing data interaction; characterized in that the method further comprises: responsive to detecting that the master card is performing the data interaction, starting foreground Public Land Mobile Net, PLMN, search for the secondary card; responsive to detecting that the master card is not performing the data interaction, starting background PLMN search for the secondary card, when the background PLMN search fails, starting the foreground PLMN search for the secondary card; and displaying operator network information found for the secondary card by the foreground PLMN search or displaying operator network information found for the secondary card by the background PLMN search; wherein when the foreground PLMN search is started, use of a network by the master card is suspended, and wherein a priority of the background PLMN search is lower than a priority for performing the data interaction by the master card, and wherein the foreground PLMN search refers to full-band search and the background PLMN search refers to partial-band search. responsive to detecting that the master card is performing the data interaction, starting foreground Public Land Mobile Net, PLMN, search for the secondary card; responsive to detecting that the master card is not performing the data interaction, starting background PLMN search for the secondary card, when the background PLMN search fails, starting the foreground PLMN search for the secondary card; and displaying operator network information found for the secondary card by the foreground PLMN search or displaying operator network information found for the secondary card by the background PLMN search; wherein when the foreground PLMN search is started, use of a network by the master card is suspended, and wherein a priority of the background PLMN search is lower than a priority for performing the data interaction by the master card, and wherein the foreground PLMN search refers to full-band search and the background PLMN search refers to partial-band search.
