The embedded Subscriber Identity Module 101 is also called an eSIM card (embedded Subscriber Identity Module), that is, a conventional Subscriber Identity Module is integrated on a terminal device chip, rather than being added to the device as an independent removable component, and a user does not need to insert a physical SIM card (Subscriber Identity Module).
The identification card connection unit 103 is used to establish an electrical connection with the subscriber identification card 105 physically.
In at least one embodiment, the SIM card 105 can be plugged into or unplugged from the SIM card connecting unit 103.
Since the controller 102 is electrically connected to the identification card connecting unit 103, the controller 102 can obtain a connection status corresponding to whether the identification card connecting unit 103 is electrically connected to the subscriber identification card 105.
The electronic device 100 provided by the embodiment of the application comprises an identification card connecting unit 103, an embedded subscriber identification chip 101, a switch switching unit 104 and a controller 102, wherein when the identification card connecting unit 103 is electrically connected with a subscriber identification card 105, the controller 102 controls the switch switching unit 104 to be switched to the identification card connecting unit 103 to connect the switch switching unit 104 and the subscriber identification card 105, so that the controller 102 can communicate with the subscriber identification card 105 through the switch switching unit 104; when the identification card connecting unit 103 is not electrically connected to the user identification card 105, the controller 102 controls the switch switching unit 104 and the embedded user identification chip 101 to be switched on, so that the controller 102 can communicate with the embedded user identification chip 101 through the switch switching unit 104, and finally, the embedded user identification chip 101 and the user identification card 105 are automatically switched when the controller 102 is started correspondingly, and convenience and flexibility of the electronic device 100 in an application process are improved.
Therefore, on one hand, for example, in a scenario where the electronic device 100 is maintained, leased, used, and subjected to an authentication and access test, the electronic device 100 accesses the user identification card 105, and then, in a process of powering up again and starting, the switch switching unit 104 can automatically connect the controller 102 and the user identification card 105, so that communication can be performed between the controller 102 and the user identification card 105, and thus when the user identification card 105 is accessed, a data traffic corresponding to the user identification card 105 is automatically used, and a traffic of the embedded user identification chip 101 itself in the electronic device 100 is prevented from being consumed; on the other hand, in a normal scenario that the electronic device 100 does not access the user identification card 105, the controller 102 and the embedded user identification chip 101 can be automatically connected through the switch switching unit 104, so that the controller 102 and the embedded user identification chip 101 can communicate with each other, and convenience, flexibility and security of the electronic device 100 during application are improved.

Wherein, when the controller 102 is powered on and started, a first control signal is generated and sent to the first switch terminal 1a, to establish a first control connection with the third switch terminal 1c of the control switch 106 through the signal detection pin 3e, at this time, if the identification card connection unit 103 establishes an electrical connection with the subscriber identification card 105, the one port of the identification card connection unit 103 outputs a high level signal, which the controller 102 can detect through the signal detection pin 3e, the level of the natural signal detection pin 3e is pulled high, from the first control connection, it is clear that the level of the third switch terminal 1c of the control switch 106 is also pulled high, then the control switch 106 controls the bus switch 107 to switch on the switch output side 2c and the identification card connection unit 103 according to the high level signal, and finally the controller 102, the switch switching unit 104, the identification card connection unit 103 and the subscriber identification card 105 form a path.
