registering a second account when determining that the SIM card of a terminal is changed from a first SIM card to a second SIM card; executing a predetermined data backup process so as to back up data corresponding to the first account to the second account; and sending a deletion instruction to a server for instructing the server to delete the data corresponding to the first account. ## Claims ### Claim 1 A data backup method, comprising: when a first account is logged in, acquiring information of a SIM (subscriber identification module) card of a terminal; when determining according to the information of the SIM card that the SIM card of the terminal is changed from a first SIM card associated with the first account to a second SIM card, registering a second account associated with the second SIM card; executing a predetermined data backup process to back up data corresponding to the first account to the second account; and sending a deletion instruction to a server corresponding to the first account, the deletion instruction being configured to instruct the server to delete the data corresponding to the first account. ### Claim 2 (depends on 1) The method according to claim 1, further comprising: sending a cancellation instruction to the server corresponding to the first account, the cancellation instruction being configured to instruct the server to cancel the first account. ### Claim 3 (depends on 2) The method according to claim 2, wherein, registering the second account associated with the second SIM card comprises: acquiring first authentication information corresponding to the first account and second authentication information corresponding to the second SIM card; and when determining that the first authentication information matches the second authentication information, registering the second account associated with the second SIM card. ### Claim 4 (canceled) ### Claim 5 (depends on 1) The method according to claim 1, wherein, executing the predetermined data backup process to back up the data corresponding to the first account to the second account comprises: sending a backup instruction to the server corresponding to the first account according to the predetermined data backup process, the backup instruction being configured to instruct the server to back up the data corresponding to the first account to the second account. ### Claim 6 (depends on 1) The method according to claim 1, wherein, executing the predetermined data backup process to back up the data corresponding to the first account to the second account comprises: sending an instruction to the server according to the predetermined data backup process, the instruction being configured to instruct the server to transmit the data corresponding to the first account to the terminal; receiving the data corresponding to the first account from the server; and after detecting that data updating occurs, uploading updated data to a storage space corresponding to the second account in the server, the updated data comprising the data corresponding to the first account. ### Claim at position 7 -13. (canceled) ### Claim 14 A non-transitory computer-readable storage medium, having a computer program stored therein, wherein when the computer program is executed on a computer, the computer is caused to perform: when a first account is logged in, acquiring information of a SIM (subscriber identification module) card of a terminal; when determining according to the information of the SIM card that the SIM card of the terminal is changed from a first SIM card associated with the first account to a second SIM card, registering a second account associated with the second SIM card; executing a predetermined data backup process to back up data corresponding to the first account to the second account; and sending a deletion instruction to a server corresponding to the first account, the deletion instruction being configured to instruct the server to delete the data corresponding to the first account. ### Claim 15 An electronic device, comprising a processor and a memory, wherein the processor is configured to call a computer program stored in the memory to perform: when a first account is logged in, acquiring information of a SIM (subscriber identification module) card of a terminal; when determining according to the information of the SIM card that the SIM card of the terminal is changed from a first SIM card associated with the first account to a second SIM card, registering a second account associated with the second SIM card; executing a predetermined data backup process to back up data corresponding to the first account to the second account; and sending a deletion instruction to a server corresponding to the first account, the deletion instruction being configured to instruct the server to delete the data corresponding to the first account. ### Claim 16 (depends on 15) The electronic device according to claim 15, wherein the processor is further configured to perform: sending a cancellation instruction to the server corresponding to the first account, the cancellation instruction being configured to instruct the server to cancel the first account. ### Claim 17 (depends on 16) The electronic device according to claim 16, wherein the processor is further configured to perform: acquiring first authentication information corresponding to the first account and second authentication information corresponding to the second SIM card; and when determining that the first authentication information matches the second authentication information, registering the second account associated with the second SIM card. ### Claim 18 (canceled) ### Claim 19 (depends on 15) The electronic device according to claim 15, wherein the processor is further configured to perform: sending a backup instruction to the server corresponding to the first account according to the predetermined data backup process, the backup instruction being configured to instruct the server to back up the data corresponding to the first account to the second account. ### Claim 20 (depends on 15) The electronic device according to claim 15, wherein the processor is further configured to perform: sending an instruction to the server according to the predetermined data backup process, the instruction being configured to instruct the server to transmit the data corresponding to the first account to the terminal; receiving the data corresponding to the first account from the server; and after detecting that data updating occurs, uploading updated data to a storage space corresponding to the second account in the server, the updated data comprising the data corresponding to the first account. ### Claim 21 (depends on 3) The method according to claim 3, wherein, the first authentication information is first user fingerprint information corresponding to the first account and the second authentication information is second user fingerprint information corresponding to the second account associated with the second SIM card. ### Claim 22 (depends on 3) The method according to claim 3, wherein, the first authentication information is a first authentication password corresponding to the first account and the second authentication information is a second authentication password corresponding to the second account associated with the second SIM card. ### Claim 23 (depends on 3) The method according to claim 3, wherein, when determining that the first authentication information matches the second authentication information, registering the second account associated with the second SIM card comprises: sending a register request carrying information of the second SIM card, so as to instruct the server to register the second account. ### Claim 24 (depends on 17) The electronic device according to claim 17, wherein, the first authentication information is first user fingerprint information corresponding to the first account and the second authentication information is second user fingerprint information corresponding to the second account associated with the second SIM card. ### Claim 25 (depends on 17) The electronic device according to claim 17, wherein, the first authentication information is a first authentication password corresponding to the first account and the second authentication information is a second authentication password corresponding to the second account associated with the second SIM card. ### Claim 26 (depends on 17) The electronic device according to claim 17, wherein, when determining that the first authentication information matches the second authentication information, registering the second account associated with the second SIM card comprises: sending a register request carrying information of the second SIM card, so as to instruct the server to register the second account.
