Disclosed in the present invention is a network locking method for a mobile terminal. An encryption chip is installed inside a mobile terminal. Customization information is saved in a Subscriber Identity Module (SIM) card, the encryption chip and a mobile terminal main chip respectively. After the mobile terminal is powered on, the encryption chip compares its customization information with that in the mobile terminal main chip and the SIM card respectively, and prevents communication between the mobile terminal main chip and the SIM card if inconsistency occurs in any comparison. Meanwhile, a mobile terminal is also disclosed in the present invention. By adopting the solution of the present invention, flexible network locking of the mobile terminal can be achieved, and under the condition that the customization information is operator information or the combination of operator information and cooperator information, the mobile terminal can be used normally in any network where the same operator or the combination of the same operator and cooperator can provide services, only if a SIM card customized by the operator is inserted, avoiding the problem that mobile terminals have to be returned to the manufactory to lock network again when they are scheduled across the networks inside the operator. |
