Once a SIM card is inserted into the mobile phone, the mobile phone acquires a phone number associated with the inserted SIM card and identifies whether the acquired phone number has been stored in the non-erasable programmable memory of the mobile phone. If yes, the user is legal and can use the mobile phone, if no, then the user is illegal and cannot use the mobile phone. Therefore, the mobile phone protects and hides stored information from the user. ## Claims ### Claim 1 A mobile phone comprising: an input unit for generating input signals in response to user inputs; a non-erasable programmable memory for storing at least one phone number, wherein each of the at least one phone number corresponds to a SIM card; a display unit for displaying information; and a control unit, further comprising: a number acquiring module for acquiring a phone number of a SIM card inserted to the mobile phone when the mobile phone is powered on; a determining module for comparing the acquired phone number with the at least one phone number in the non-erasable programmable memory and determining whether the non-erasable programmable memory has stored the phone number of the inserted SIM card; and an output control module for controlling the display unit to display information which prompts authentication success when the determining module determines that the non-erasable programmable memory has stored the phone number of the inserted SIM card, and for controlling the display unit to display information which prompts authentication fail when the determining module determines that the phone number of the inserted SIM card does not exist in the non-erasable programmable memory. ### Claim 2 (depends on 1) The mobile phone as recited in claim 1, wherein the control unit further comprises a defining module for controlling the display unit to display a user interface and defining the at least one phone number in the user interface in response to user inputs from the input unit. ### Claim 3 (depends on 2) The mobile phone as recited in claim 2, wherein the defining operation from the defining module can be performed when the user starts to use the mobile phone the first time or in the course of using the mobile phone. ### Claim 4 (depends on 2) The mobile phone as recited in claim 2, wherein the control unit further comprises an encrypting module for encrypting the user interface after the defining module defines the at least one phone number in the user interface. ### Claim 5 (depends on 4) The mobile phone as recited in claim 4, wherein the encrypting module sets a password for the user interface in response to user inputs, if a user enters the right password for the user interface, the user can look at, change, or delete the at least one phone number of the user interface. ### Claim 6 (depends on 2) The mobile phone as recited in claim 2, wherein the control unit further comprises a storage control module for storing the at least one phone number defined the defining module in the non-erasable programmable memory. ### Claim 7 A SIM card authentication method adapted for a mobile phone, wherein the mobile phone comprises a non-erasable programmable memory for storing at least one phone number, and each of the at least one phone number corresponds to a SIM card, the method comprising: acquiring a phone number of a SIM card inserted to the mobile phone when the mobile phone is powered on; comparing the acquired phone number with the at least one phone number in the non-erasable programmable memory and determining whether the non-erasable programmable memory has stored the phone number of the inserted SIM card; and displaying information which prompts authentication success if the non-erasable programmable memory has stored the phone number of the inserted SIM card, and displaying information which prompts authentication fail if the phone number of the inserted SIM card does not exist in the non-erasable programmable memory. ### Claim 8 (depends on 7) The SIM card authentication method as recited in claim 7, further comprising: displaying a user interface and defining the at least one phone number in the user interface in response to user inputs. ### Claim 9 (depends on 8) The SIM card authentication method as recited in claim 8, wherein the defining step can be performed when the user starts to use the mobile phone the first time or in the course of using the mobile phone. ### Claim 10 (depends on 8) The SIM card authentication method as recited in claim 8, further comprising: encrypting the user interface after defining the at least one phone number. ### Claim 11 (depends on 10) The SIM card authentication method as recited in claim 10, wherein the encrypting step is “setting a password for the user interface in response to user inputs”, if a user enters the right password for the user interface, the user can look at, change, or delete the at least one phone number of the user interface. ### Claim 12 (depends on 8) The SIM card authentication method as recited in claim 8, further comprising: storing the defined at least one phone number in the non-erasable programmable memory.
