Disclosed in the present document is a network locking method for a mobile terminal. An encryption chip is built in the mobile terminal, and customization information is saved in a Subscriber Identity Module (SIM) card, an encryption chip and a mobile terminal main chip respectively. After the mobile terminal is powered on, the encryption chip compares its customization information with those 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 any comparison shows that the information is inconsistent; Meanwhile, a mobile terminal is also disclosed in the present document. With the solution of the present document, flexible network locking of the mobile terminal can be achieved, and in the case that the customization information is operator information or the combination of operator information and partner information, the mobile terminal can work normally in any network where the same operator or the combination of the same operator and partner can provide services, as long as a SIM card customized by the operator is inserted, thus 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. |
