Abstract
The disclosure discloses a method for shielding a short message receiving function. The method includes the following steps of: storing parameters related to short-message-receiving-function-shielding in an Element File (EF) in a Subscriber Identity Model (SIM) card; performing inter-verification by utilizing the EF in the SIM-card and a Non Volatile (NV) random access memory in a data card to determine whether the SIM-card is applied to the data card; and when the SIM-card is determined to be applied to the data card, reporting the parameters related to short-message-receiving-function-shielding to a network during the process of attaching mobile terminal to the network. Compared with the conventional art, the technical solution of the disclosure can shield the short message receiving function without generating short message fee, so as to enhance the stability of the data service to a large extent and increase the flexibility for a subscriber in selecting the service type at the terminal.
