Abstract
A network locking method and device for a mobile terminal are provided in the present document, wherein network locking information and verification signals of a mobile terminal and a subscriber identify module (SIM) card are respectively stored in both parties in advance; after the mobile terminal is powered on, the mobile terminal and the SIM card verify each other through the verification signals; if the both parties pass through the verification performed by the other party, the mobile terminal compares the stored network locking information with the network locking information in the SIM card; if the comparison result indicates consistency, the mobile terminal enters into a normal standby state.
Claims11
A network locking method for a mobile terminal, wherein, network locking information and verification signals of a mobile terminal and a subscriber identify module (SIM) card are respectively stored in both parties in advance;
- the method further comprising:
- after said mobile terminal is powered on, said mobile terminal and said SIM card verifying each other through the verification signals, if the both parties pass through said verification performed by the other party, said mobile terminal comparing the stored network locking information with the network locking information in said SIM card, and if a comparison result indicates consistency, said mobile terminal entering into a normal standby state.
