Referring to fig. 2, a schematic flow chart of a network card locking method is provided in the embodiment of the present application. In this embodiment, a network card locking method is applied to a terminal for example, and the network card locking method may include the following steps:

s201, reading an integrated circuit card identification code (ICCID) of the SIM card.

Wherein, a SIM (Subscriber Identity Module) card is an IC card held by a mobile Subscriber of the GSM system, and is called a Subscriber Identity Module card; the GSM system identifies GSM users through SIM cards, the same SIM card can be used on different mobile phones, and the GSM mobile terminal can be accessed to the network only after the SIM card is inserted. The ICCID (integrated circuit card identification code), i.e., the SIM card number, is equivalent to an identification card of a mobile phone number. The ICCID is a unique identification number of the IC card and is composed of 20 digits, and the coding format is as follows: XXXXXXX 0MFSS YYGXXXX.

Generally, network locking of a SIM card is implemented by a network card locking scheme based on a protocol standard, and the network locking types include 5 types: network Lock Network Lock, locking MCC + MNC; a sub-Network Lock Network Subset Lock locks MCC + MNC + sub-Network number (6-7 bits of IMSI); service provider sp (service provider) lock, locking MCC + MNC + GID 1; the company Lock corporation Lock, Lock MCC + MNC + GID1+ GID 2; and the SIM card lock locks the appointed SIM card. Most communication operators Lock only Network Lock, Network Subset Lock, SP Lock, and corporation Lock, not much.

The terminal can not acquire network service when the current SIM card network is locked, and can register to an operator network through the SIM card after a user inputs an unlocking code to unlock; the terminal can directly register to the operator network through the SIM card in the state that the current SIM card network is not locked.

Generally, the full-matching query refers to performing full-matching query on each field of the ICCID code of the SIM card, that is, when each field of the ICCID code of the SIM card is not completely consistent with the ICCID code of the SIM card in the blacklist of the server, it indicates that the network of the SIM card is not locked, that is, the card-locking state information of the SIM card is in an unlocked state; or when each field of the ICCID code of the SIM card is completely consistent with the ICCID code of the SIM card in the white list of the server, it indicates that the network of the SIM card is not locked, that is, the card-locking status information of the SIM card is in an unlocked status.

S504, when the ICCID is determined not to be the ICCID in the white list or when the ICCID is determined to be the ICCID in the black list, the card locking state information of the SIM card is determined to be the locking state.

Generally, the full-matching query refers to performing full-matching query on each field of the ICCID code of the SIM card, that is, when each field of the ICCID code of the SIM card is completely consistent with the ICCID code of the SIM card in the blacklist of the server, it indicates that the network of the SIM card is locked, that is, the card-locking state information of the SIM card is in a locked state; or when each field of the ICCID code of the SIM card is not completely consistent with the ICCID code of the SIM card in the white list of the server, it indicates that the network of the SIM card is locked, that is, the card-locking status information of the SIM card is in a locked status.

And S505, sending the card locking state information to the terminal.

S506, receiving an unlocking code corresponding to the SIM card sent by the terminal.

Generally, when a terminal knows that a current SIM card is locked, that is, the terminal cannot register to an operator network through the current SIM card, the terminal displays a notification message that the current SIM card is locked through a display unit, and displays an unlocking code input box through the display unit, and a user can input an unlocking code in the unlocking code input box, so that the terminal can acquire the unlocking code and send the unlocking code to a server.

And S507, verifying the unlocking code to obtain verification result information.

Generally, a server receives an unlocking code corresponding to a current SIM card sent by a terminal, and verifies the unlocking code to obtain verification result information: comparing the unlocking code corresponding to the current SIM card with the unlocking code in the unlocking code configuration file stored in the server, and when the unlocking code corresponding to the current SIM card is consistent with the unlocking code in the unlocking code configuration file, indicating that the verification result information is successful; and when the unlocking code corresponding to the current SIM card is inconsistent with the unlocking code in the unlocking code configuration file, indicating that the verification result information is verification failure.

And S508, sending the verification result information to the terminal.

Generally, after the server completes the verification, verification result information is generated and sent to the terminal, so that the terminal can receive the verification result information of the unlock code. When the unlocking code corresponding to the current SIM card is consistent with the unlocking code in the unlocking code configuration file of the server, the verification result information is verified successfully, the server sends the verification result information to the terminal, and the terminal registers the current SIM card to an operator network after receiving the verification result information, so that a user can obtain network service through the terminal. When the unlocking code corresponding to the current SIM card is inconsistent with the unlocking code in the unlocking code configuration file, the verification result information is proved to be verification failure, the server sends the verification result information to the terminal, and after the terminal receives the verification result information, the terminal displays the reminding information of the unlocking failure through the display unit.

According to the network card locking method provided by the scheme, the server receives an integrated circuit card identification code (ICCID) sent by the terminal, inquires whether the ICCID is an ICCID in a white list or a black list, determines that the card locking state information of the SIM card is in an unlocked state when the ICCID is determined to be the ICCID in the white list or not, determines that the card locking state information of the SIM card is in a locked state when the ICCID is determined not to be the ICCID in the white list or not, and sends the card locking state information to the terminal, receives an unlocking code corresponding to the SIM card sent by the terminal, verifies the unlocking code to obtain verification result information, and sends the verification result information to the terminal. By the method, the network locking of the specific SIM card can be realized, and the network locking efficiency and convenience of the specific SIM card are improved; and when the user inquires the unlocking code corresponding to the SIM card, the server generates the corresponding unlocking code according to the IMEI of the terminal and the ICCID of the SIM card, thereby reducing the flow of producing the corresponding unlocking code in the production process of customizing the terminal by an operator and reducing the complexity of the production flow of customizing the terminal by the operator.
