Communication device and start up method thereof

A communication device, the communication device comprising:

• a current subscriber identification module (SIM) card;
• a storage device;
• at least one processor;
• one or more programs stored in the storage device and being executable by the at least one processor, the one or more programs comprising:
• a detecting module operable to receive powered on signals to start up the communication device, determine if the communication device has been locked with a designated SIM card by determining if the communication device has a preset lock password;
• a comparing module operable to acquire a unique International Mobile Subscriber Identity (IMSI) code of the current SIM card if the communication device has been locked with the designated SIM card, and determine if the acquired IMSI code matches a prestored IMSI code of the designated SIM card in the storage device;
• a controlling module operable to start up the communication device if the acquired IMSI code matches the prestored IMSI code in the storage device;
• an unlocking module operable to unlock the designated SIM card with the communication device if the acquired IMSI code does not match the prestored IMSI code in the storage device;
• and
• the controlling module further operable to start up the communication device if the designated SIM card has been unlocked with the communication device, or power off the communication device if the designated SIM card has not been unlocked with the communication device.

A storage medium storing a set of instructions, the set of instructions capable of being executed by a processor to perform a method for starting up a communication device, the communication device comprising a current subscriber identification module (SIM) card, the method comprising:

• receiving powered on signals to start up the communication device;
• determining if the communication device has been locked with a designated SIM card by determining if the communication device has a preset lock password;
• acquiring a unique International Mobile Subscriber Identity (IMSI) code of the current SIM card if the communication device has been locked with the designated SIM card;
• determining if the acquired IMSI code matches a prestored IMSI code of the designated SIM card in a storage device of the communication device;
• starting up the communication device if the acquired IMSI code matches the prestored IMSI code in the storage device;
• or
• unlocking the designated SIM card with the communication device if the acquired IMSI code does not match the prestored IMSI code in the storage device;
• and
• starting up the communication device if the designated SIM card has been unlocked with the communication device, or powering off the communication device if the designated SIM card has not been unlocked with the communication device.
