MOBILE TERMINAL AND NETWORK UNLOCKING METHOD AND SYSTEM THEREOF

摘要

A network unlocking method of a mobile terminal is provided by the present invention. The method includes that: after being used, the mobile terminal locking the network transmits hardware information to a network sever (101); when the mobile terminal needs to unlock network, logs in a web site providing the download of a network unlocking file, the web site obtains the hardware information of the currently logging-in mobile terminal and performs the hardware information match by the network server (103); when the match succeeds, the mobile terminal downloads the network unlocking file from the web site and unlocks the network by using an unlocking code in the network unlocking file. A mobile terminal and a network unlocking system thereof are provided by the present invention. The technical solution of the present invention enables that the manner of unlocking the network is not influenced by changing the Subscriber Identity Module (SIM) card and is not restricted by whether the SIM card supports the manner of unlocking the network, hence the requirements for the operator server are reduced.
