Abstract

A method for activating a soft SIM card, a method for a soft SIM card to join network, a terminal and a network access device are provided. The method for activating includes: acquiring information on a terminal in which a soft SIM card is located of a bounding object corresponding to the soft SIM card; generating first key information according to information of the soft SIM card and the information on the terminal in which the soft SIM card is located of the bounding object and according to a predefined encryption policy; comparing whether the first key information is consistent with preset key information corresponding to the soft SIM card, if consistent, allowing an activation of the soft SIM card, so as to enable a user to perform network communication via the soft SIM card. The technical solutions are beneficial for improving the application security of the soft SIM card.
