A communication method for a user equipment (UE) may include: sending a subscription request for a first network; receiving information regarding an identifier of a first profile associated with the first network and the date on which the first profile is deactivated; and determining whether a subscription to the first network is allowed on the basis of the date information. Accordingly, in an environment such as Universal Terrestrial Radio Access Network (UTRAN), GSM/EDGE Radio Access Network (GERAN) or Evolved UTRAN (EUTRAN), when a device having an eSIM attempts to make a re-subscription to an MNO, or when the device attempts to make a re-subscription or additional subscription to an MNO according to a national electricity or infrastructure plan for M2M equipment, it is possible to accommodate MNO policies and determine whether a re-subscription to an MNO is allowed according to the MNO policies. When MNO re-subscription is not allowed, a lock may be placed so as to update or reconfigure communication and security information in an easy and safe manner."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Security method and system for supporting re-subscription or additional subscription restriction policy in mobile communications","description":"Provided is a system that enables a device to perform a communication function.
