Abstract: This application discloses a method for automatically activating an NFC application and a terminal, and relates to the terminal field. When a terminal has a plurality of SEs, an NFC application accessed by a transaction instruction is automatically activated. The terminal may include an NFC controller and at least two SEs, and each of the at least two SEs carries at least one NFC application. A specific solution is as follows: The NFC controller receives a transaction instruction, determines a target SE from the at least two SEs according to the transaction instruction, and sends the transaction instruction to the target SE; the target SE receives the transaction instruction, and determines, according to the transaction instruction, a target NFC application from an NFC application carried in the target SE; and the target SE runs the target NFC application, and executes the transaction instruction.

Abstract: This application relates to the field of communications technologies, and in particular, to a profile download technology. In a profile download method, a primary device obtains an embedded integrated circuit card identifier (EID) of a secondary device, where the EID is used by the primary device to obtain, from a mobile operator server, profile download information that matches the EID; receives the profile download information from the mobile operator server; and sends the profile download information to the secondary device, where the profile download information is used by the secondary device to download a profile from a profile management server, and the profile is installed in an embedded UICC (eUICC) of the secondary device after the download is complete.

Abstract: An embedded subscriber identification module (eSIM) card change method and a related device are disclosed. The method includes receiving, by an entitlement server, a first card change request sent by a terminal device, where the first card change request includes a user account, a password, a user number, and embedded universal integrated circuit card (eUICC) identification. The method further includes verifying a user identity of the terminal device based on the user account and the password. If the verification succeeds, a second card change request is sent to an operator business support system (BSS). The second card change request includes the user number and the eUICC identification, and the second card change request is used to indicate to the BSS to complete the eSIM card change and to indicate to an eSIM server to generate an eSIM profile and associate the eSIM profile with the eUICC identification.

Abstract: Embodiments of this application provide a SIM module management method and an electronic device, and relate to the field of electronic devices. A solution that supports an eSIM module is provided for an existing electronic device that supports dual SIM modules, so that the dual SIM modules are compatible with the eSIM module. The electronic device in the embodiments of this application may support three SIM modules. The three SIM modules include at least one eSIM module. The remaining two SIM modules may be both plug-in SIM modules, or may be one plug-in SIM module and one softSlM module. A user can arbitrarily select two SIM modules from the three SIM modules to be in online standby mode, or can arbitrarily select one SIM module from the three SIM modules to be in online standby mode.

Abstract: In an example method, a device A may send SIM card information of device A to device B, and device B can use the SIM card information of device A as SIM card information of a virtual SIM card in device B. Device B may access the Internet, make and answer calls, and receive and send SMS messages through the SIM card of device A. The technical solutions provided in this application are implemented, so that when device B has no SIM card, or a SIM card inserted into the device B has no service, the SIM card of device A may be used to access the Internet, make and answer calls, and receive and send SMS messages.

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.

Abstract: A matrix operation method is provided, applied to an accelerator configured to perform a matrix operation. A matrix operation accelerator (100) respectively stores, in response to a received matrix operation instruction, subsets of a first matrix and subsets of a second matrix in a first storage space and a second storage space of a memory (120); stores, in a third storage space of the memory (120), subsets obtained after the subsets of the first matrix are multiplied by the subsets of the second matrix; and performs matrix operations on the subsets of the first matrix and the subsets of the second matrix based on the matrix operation instruction, to obtain matrix operation results. The dedicated matrix operation accelerator (100) is used to perform a matrix operation, so that a large-scale matrix operation can be completed in relatively short time, thereby offloading a matrix operation burden of a processor.
