An anti-crack method for a network-locked mobile terminal is provided. The method includes the following steps: when a mobile terminal starts up, a Subscriber Identity Module (SIM) card reports first network lock information to the mobile terminal; when the mobile terminal is in an activated network-locked state, it judges whether the first network lock information is legal; if the first network lock information is illegal, the mobile terminal locks the SIM card; and if the first network lock information is legal, the mobile terminal initiatively read the second network lock information and judge whether the second network lock information is legal; if the second network lock information is legal, the mobile terminal begins to search the network; and if the second network lock information is illegal, the mobile terminal locks the SIM card. Accordingly, a network-locked mobile terminal is provided, which includes: a SIM card, an activation judging module, a network locking module, a network searching module, a card locking module, and an anti-crack device. An anti-crack device for the network-locked mobile terminal is also provided, which includes: an initialization judging unit, a reading unit, and a judgment unit. Thus, the present method is able to prevent the network-locked mobile terminal from being cracked. |
