Dynamic activation method, device and system for configuration file and storage medium

The invention provides a dynamic activation method, device and system for a configuration file and a storage medium. The method comprises the following steps of receiving a configuration file activation instruction sent by an operator/virtual operator platform, wherein the configuration file activation instruction comprises an identifier, with an IMSI corresponding to the identifier and a file state parameter, and a configuration file of a preparation state corresponding to the identifier is found out according to the identifier; wherein the IMSI of the configuration file in the preparation state is an initial IMSI; when the IMSI conforms to the rule and the configuration file of the preparation state conforms to the state transition condition, updating the initial IMSI by adopting the IMSI; and performing state updating on the updated configuration file in the preparation state according to the file state parameter to obtain a configuration file in an available state. The method can effectively prevent the v
