The text message of the demo machine suddenly disappeared.

Does the subject want to ask, "What happened when the short message on the mobile phone suddenly disappeared?" Mobile phone hardware is damaged, there is a problem with SMS settings, and the backup will not be restored.

1, check whether the phone is restarted. If there is no obvious fault or damage to the mobile phone, please check whether the mobile phone is restarted, and the information will be restored after the restart.

2. Check the SMS settings. The reason why SMS disappears is that the system settings have changed, so it is necessary to check whether the SMS settings are wrong.

3. Restore the backup. If iCloud backup is turned on or other backup methods are used, you can try to recover data from the backup.
