Disclosed are apparatus and methods for controlling SIM cards. An apparatus which is paired with a second terminal comprises: a SIM card; state checking means which checks the state of the paired terminal with identical identification information as the first SIM card; and activation control means which controls SIM card activation depending on the state of the paired terminal. Using this configuration, the present invention makes it possible for a user to maintain multiple terminals using the same phone number with one billing statement without the help of a service provider through SIM card control.
