Embodiment Construction
[0037] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0038] If the current mobile terminal needs to use the operator's network, it needs to install a SIM card issued by the operator through the SIM card slot, and the user key information is stored inside as the network access certificate and billing certificate. However, the size of the SIM card itself is too large, and a corresponding card tray (SIM card connector) needs to be provided on the main board of the mobile terminal for matching. The tray occupies too much space, which is not conducive to the problem of reducing the cost of the mobile terminal.

The invention discloses a method for realizing a mobile terminal without an SIM (Subscriber Identity Module) card slot, the mobile terminal and a medium. The method comprises the following steps: dividing a specific storage area in an internal memory of the mobile terminal in advance for only storing key information of an operator; when a mobile terminal accesses a certain operator number, the mobile terminal is connected with a number key read-write device special for an operator, and key information of the operator number is written into a specific storage area of the mobile terminal through a specified command; and when registration is carried out, reading the key information of the operator stored in the specific storage area, and sending the key information to an operator base station for authentication to complete network registration. According to the invention, an SIM card slot does not need to be arranged in the mobile phone of the mobile terminal, the original SIM function is stored in a specific area of the memory of the mobile terminal, and the key storage mode of an operator on the mobile terminal is changed, so that the occupation of the internal space of the mobile terminal is reduced, the hardware cost of the mobile terminal is reduced, and convenience is provided for the use of a user.
Description
technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a method for realizing a mobile terminal without a SIM card slot, a mobile terminal and a storage medium. Background technique [0002] With the development of science and technology and the continuous improvement of people's living standards, the use of various mobile terminals such as mobile phones is becoming more and more popular. [0003] If the current mobile terminal needs to use the operator's network, it needs to install a SIM card issued by the operator through the SIM card slot, and the user key information is stored inside as the network access certificate and billing certificate. However, the size of the SIM card itself is too large, and a corresponding card tray (SIM card connector) needs to be provided on the main board of the mobile terminal for matching. The tray occupies too much space, which is not conducive to reducing the cost of the mobile terminal...
