Description

technical field

[0001] The invention relates to the field of electronic technology, in particular to a SIM card information protection method and device. Background technique

[0002] At present, a user can enjoy services such as calling and surfing the Internet provided by a mobile operator through an electronic device installed with a Subscriber Identification Module (SIM). The application program (Application, APP) installed on the electronic device can read the parameter information of the SIM card, such as phone number, short message information, contact information, and the like. In order to prevent leakage of user personal information, the technical solution adopted in the prior art generally restricts the authority of the APP, so that it cannot obtain relevant parameter information. However, for some APPs, if the permissions are restricted, some or even all functions of the APP cannot be used. Therefore, there is a technical problem in the prior art that the normal...
