Abstract

Embodiments of this application provide a SIM module management method and an electronic device, and relate to the field of electronic devices. When an eSIM module is in position and it is detected that a second plug-in SIM module is inserted into a second SIM module interface, the electronic device detects whether a first plug-in SIM module is inserted into a first SIM module interface. If the first SIM module interface is connected to the first plug-in SIM module, a user is prompted to select the second plug-in SIM module or the eSIM module. If the first SIM module interface is not connected to the first plug-in SIM module, the user is prompted to connect the second plug-in SIM module to the first SIM module interface.

Claims (48)

1. An electronic device, comprising:

a first modem,

a second modem,

a mobile communication module,

a first subscriber identity module (SIM) module interface,

a second SIM module interface,

an embedded universal integrated circuit card (eUICC) configured to store an embedded subscriber identity module (eSIM) module, a first smart card interface (SCI), and a second SCI; and

a processor coupled to the first modem, the second modem, the mobile communication module, the first SIM module interface, the second SIM module interface, and the eUICC, wherein

one end of the first SCI is coupled to the processor, and the other end is coupled to the second SIM module interface and the eUICC;

one end of the second SCI is coupled to the processor, and the other end is coupled to the first SIM module interface and the eUICC; and

the processor is configured to control a connection relationship between the first SIM module interface, the second SIM module interface, and the eUICC and the first modem and the second modem.

2. The electronic device according to claim 1 , wherein the processor is further configured to:

when the eUICC is connected to the first SCI and detected that a second plug-in SIM module is connected to the second SIM module interface and a first plug-in SIM module is connected to the first SIM module interface, provide first prompt information used to prompt that at most two of the first plug-in SIM module, the second plug-in SIM module, and the eSIM module are simultaneously used.

3. The electronic device according to claim 1 , wherein the processor is further configured to:

when the eUICC is connected to the first SCI and detected that a second plug-in SIM module is connected to the second SIM module interface and the first SIM module interface is not connected to a first plug-in SIM module, automatically connect the eUICC to the second SCI, and connect the second SIM module interface to the first SCI.

4. The electronic device according to claim 1 , wherein the processor is further configured to:

when the eUICC is connected to the first SCI and detected that a second plug-in SIM module is connected to the second SIM module interface and the first SIM module interface is not connected to a first plug-in SIM module, provide second prompt information used to prompt whether to switch the eUICC to the first SIM module interface.

5. The electronic device according to claim 4 , wherein the processor is further configured to:

when an input operation performed based on the second prompt information is received and the eUICC is kept connected to the first SCI, provide third prompt information used to prompt to connect the second plug-in SIM module to the first SIM module interface.

6. The electronic device according to claim 1 , wherein when detecting that the eSIM module is installed and activated, the processor is further configured to perform following operations:

obtaining card information of the eSIM module; and

if the first SIM module interface is not connected to a first plug-in SIM module and the second SIM module interface is connected to a second plug-in SIM module, downloading the eSIM module to the first SIM module interface.

7. The electronic device according to claim 1 , wherein when detecting that the eSIM module is installed and activated, the processor is further configured to perform following operations:

obtaining card information of the eSIM module; and

if the first SIM module interface is not connected to a first plug-in SIM module and the second SIM module interface is connected to a second plug-in SIM module, providing fourth prompt information used to prompt to download the eSIM module to the first SIM module interface.

8. The electronic device according to claim 1 , wherein when detecting that the eSIM module is installed and activated, the processor is further configured to perform following operations:

obtaining card information of the eSIM module; and

if the first SIM module interface is connected to a first plug-in SIM module and the second SIM module interface is connected to a second plug-in SIM module, providing fifth prompt information used to prompt to disable the first plug-in SIM module or the second plug-in SIM module.

9. A subscriber identity module (SIM) module management method applied to an electronic device comprising:

a processor,

a first SIM module interface,

a second SIM module interface, and

an embedded universal integrated circuit card (eUICC) configured to store an embedded subscriber identity module (eSIM) module and a first smart card interface (SCI), wherein

one end of the first SCI is coupled to the processor, and the other end is coupled to the second SIM module interface and the eUICC; and the electronic device is connected to a network through either of a second plug-in SIM module and a currently activated eSIM module in the eUICC, and a first plug-in SIM module; and the method comprising:

when the eUICC is connected to the first SCI and detected that the second SIM module interface is connected to the second plug-in SIM module, performing following operations:

detecting whether the first SIM module interface is connected to the first plug-in SIM module; and

if the first SIM module interface is connected to the first plug-in SIM module, providing sixth prompt information used to prompt to connect the second SIM module interface to the second plug-in SIM module or the eSIM module; or

if the first SIM module interface is not connected to the first plug-in SIM module, providing seventh prompt information used to prompt to connect the second plug-in SIM module to the first SIM module interface.

10. A subscriber identity module (SIM) module management method applied to an electronic device connected to a network through two of a first plug-in SIM module, a second plug-in SIM module, and a currently activated eSIM module in an embedded universal integrated circuit card (eUICC), the method comprising:

when the eUICC is connected to a first smart card interface (SCI) and detected that the second plug-in SIM module is connected to a second SIM module interface, performing following operations:

detecting whether a first SIM module interface is connected to the first plug-in SIM module; and

if the first plug-in SIM module is connected to the first SIM module interface, providing first prompt information used to prompt that at most two of the first plug-in SIM module, the second plug-in SIM module, and the eSIM module are simultaneously used.

11. The method according to claim 10 , further comprising:

if the first SIM module interface is not connected to the first plug-in SIM module, automatically connecting the eUICC to a second SCI.

12. The method according to claim 10 , further comprising:

if the first SIM module interface is not connected to the first plug-in SIM module, providing second prompt information used to prompt whether to switch the eUICC to the first SIM module interface.

13. The method according to claim 12 , wherein after providing the second prompt information, the method further comprises:

when an input operation performed based on the second prompt information is received and the eUICC is kept connected to the first SCI, providing third prompt information used to prompt to connect the second plug-in SIM module to the first SIM module interface.
