reading information about a national ID and a network ID of the auxiliary SIM card; and

comparing the read information about the national ID and the network ID of the auxiliary SIM card with information about national IDs and network IDs allowed to be used in a standard mobile communication terminal national ID and network ID information list;

if the read information about national ID and network ID of the auxiliary SIM card is inconsistent with the information about national IDs and network IDs allowed to be used in the standard mobile communication terminal national ID and network ID information list, determining that the auxiliary SIM card is locked;

if the auxiliary SIM card is locked, stopping a response to receiving the incoming call, and waiting for receipt of an instruction of whether to send a prompt message to inform a caller for the incoming call; and

upon receiving an instruction of sending a prompt message to inform the caller for the incoming call, transmitting a prompt message to the caller with the master SIM card.

6. The incoming call management method of a mobile communication terminal of claim 5 , wherein the step of transmitting a prompt message to the caller with the master SIM card comprises:

a step of transmitting a prompt message that is automatically generated to the caller with the master SIM card.

7. The incoming call management method of a mobile communication terminal of claim 5 , wherein the step of stopping a response to receiving the incoming call of the auxiliary SIM card when the auxiliary SIM card is locked further comprises a step of prompting a user that the auxiliary SIM card is locked.

8. The incoming call management method of a mobile communication terminal of claim 5 , wherein if the information about the national ID and the network ID of the auxiliary SIM card is inconsistent with the information about the national IDs and the network IDs allowed to be used in the standard mobile communication terminal national ID and network ID information list, the method includes determining that the auxiliary SIM card is a non-prefabricated card.

9. The incoming call management method of a mobile communication terminal of claim 5 , including:

reading information about a national ID and a network ID of the master SIM card;

comparing the read information about the national ID and the network ID of the master SIM card with information about national IDs and network IDs allowed to be used in a standard mobile communication terminal national ID and network ID information list; and

if the read information about the national ID and the network ID of the auxiliary SIM card is inconsistent with the information about national IDs and network IDs allowed to be used in the standard mobile communication terminal national ID and network ID information list, determining that the master SIM card is locked.

10. A mobile communication terminal comprising a master SIM card and an auxiliary SIM card, wherein the mobile communication terminal comprises:

a communication management module configured to, in response to receiving an incoming call to the auxiliary SIM card, determine whether the auxiliary SIM card is locked, wherein the communication management module comprises:

an information reading unit used for reading information about a national ID and a network ID of the auxiliary SIM card; and

an information comparison unit used for comparing the read information about the national ID and the network ID of the auxiliary SIM card with information about national IDs and network IDs allowed to be used in a standard mobile communication terminal national ID and network ID information list: and

if information about the national ID and the network ID of the auxiliary SIM card is inconsistent with information about national IDs and network IDs allowed to be used in the standard mobile communication terminal national ID and network ID information list, determining that the auxiliary SIM card is locked;

a prompt management module configured to, if the auxiliary SIM card is locked, stop responding to the incoming call and wait for an instruction as to whether to send a prompt message to inform a caller for the incoming call; and

an information transmission module configured to, in response to receiving an instruction of sending a prompt message to inform the caller for the incoming call, transmit a prompt message to the caller with the master SIM card.
