Abstract

A terminal and a method for binding Subscriber Identification Module (SIM) cards are provided. During an initialization of a SIM card, the terminal sends a terminal profile command to inform related items of a SIM Tool Kit (STK) supported by the SIM card. The SIM card provides the SIM card related operator information to the terminal by actively reporting a proactive command or providing menu items. The terminal judges whether the SIM card operator information of the STK function matches with the SIM card operator information stored in the terminal or not, if they match, the terminal allows the user to normally use the terminal; otherwise or the STK function does not provide the SIM card related operator information, the terminal does not allow the user to normally use the terminal. Therefore, the purpose of locking cards by the terminal is realized with the STK function of the SIM card.

Claims2

Dependent claims

A method for a terminal binding subscriber identification module (SIM) cards, comprising:

during an initialization of a SIM card, the terminal sending a terminal profile command to the SIM card to inform the SIM card the relevant SIM Tool Kit (STK) items that are supported by the terminal;
after the STK of the SIM card is informed of the terminal supporting a proactive command, the STK of the SIM card issuing a proactive command to the terminal;
and
the terminal, after receiving the proactive command, judging whether operator information of the SIM card is provided by the STK of the SIM card;
when the operator information of the SIM card is not provided by the STK of the SIM card, the terminal determining that the SIM card is not the one bound with the terminal, and not allowing the user to use the terminal with the SIM card,
when the operator information of the SIM card is provided by the STK of the SIM card, the terminal judging whether the operator information of the SIM card provided by the STK of the SIM card is consistent with the operator information of the SIM card supported by the terminal and stored in the terminal;
when they are consistent, allowing a user to normally use the terminal with the SIM card;
when they are not consistent, not allowing the user to use the terminal with the SIM card.
