A method includes: establishing a connection with a virtual SIM card server in a first network using a global virtual SIM card of a terminal to acquire a regional virtual SIM card from the virtual SIM card server, wherein the regional virtual SIM card is configured to allow the terminal to access a second network; determining whether the global virtual SIM card of the terminal is in conflict; updating a count of conflicts in response to determining that the global virtual SIM card of the terminal is in conflict; and upon elapse of a wait period, replacing the global virtual SIM card of the terminal with a new one to acquire the regional virtual SIM card, wherein the wait period is determined according to the count of conflicts and an identifier of the terminal.
