<p>A method and a device for controlling a data card APN locking state, a data card and a method for dialing by using the data card. The control method comprises the following steps of: after the data card receives an APN parameter setting instruction as a manager user instruction, modifying a APN locking state of a current data card according to a locking state parameter carried in the instruction, and writing an APN parameter and the APN locking state carried in the instruction into a nonvolatile storage area; the dialing method comprises the following steps of: when a dialing connection is established, PC side dialing software querying the APN locking state of the data card, and if the current data card is in a locked state, only using an APN parameter set in a default PDP Profile to establish a dialing connection. According to the foregoing technical solution, a setting authority of a user on the APN parameter may be controlled when a network is accessed, so that the user may only use a specific APN parameter to access a specific network in a specific application scenario, so as to meet demands of different users for a network access authority.</p> |
