Method for selecting global roaming virtual sim card within terminal and terminal therefor

A method for selecting a global roaming virtual subscriber identity module (SIM) card within a terminal, applicable to the terminal, the method comprising:

• S1, prior to interaction between the terminal and a server based on a local virtual SIM card within the terminal after startup, checking whether registration record information of at least one local virtual SIM card within a region where the terminal resides is stored in the terminal, wherein a specified number of local virtual SIM cards of various operators are stored in the terminal;
• S2, in a case that the registration record information is stored, selecting a first local virtual SIM card corresponding to a successful registration based on the registration record information to interact with the server;
• S3, receiving remote virtual SIM card information for registration within a region where the terminal currently belongs from the server within a specified time period, wherein the remote virtual SIM card information is delivered by the server based on the first local virtual SIM card;
• and
• S4, determining whether the remote virtual SIM card information is successfully received within the specified time period, and updating registration record information of the first local virtual SIM card based on information indicating whether the remote virtual SIM card information is successfully received;
• wherein the registration record information is stored in a specified format and comprises a registration time, an indicator indicating whether registration is successful, a region where the terminal belongs, an identifier of a local virtual SIM card, and a successfully registered public land mobile network (PLMN), the local virtual SIM card is a bootstrap SIM card shared by a plurality of terminals;
• and the registration record information of the first local virtual SIM card is record information indicating whether a terminal using the first local virtual SIM card is successfully registered based on the first local virtual SIM card within the specified time period.
