If it's an Apple phone:

Method 1: Restore from iTunes backup. If your phone has been backed up, connect it to your computer, open iTunes, click the device image, click This Computer, click Restore Backup, and then click Restore.

The second method is to restore through iCould backup. Log in to iCloud official website, enter your password, and click the settings icon to restore the corresponding mobile phone data.

Apple users can restore photos and contact information that have been deleted by mistake. But the storage time is only 30 days, after which the file will be permanently deleted.
