If you have accidentally deleted your contacts from your iPhone and need to recover them, there are several methods you can try:


Restore from iCloud Backup: If you have an iCloud backup that was taken before the contacts were deleted, you can restore your iPhone from that backup. Go to Settings > General > Reset > Erase All Content and Settings. After your iPhone restarts, select "Restore from iCloud Backup" and choose the backup that contains your deleted contacts.


Restore from iTunes Backup: If you have an iTunes backup that was taken before the contacts were deleted, you can restore your iPhone from that backup. Connect your iPhone to your computer and open iTunes. Click on the iPhone icon in the top left corner and select "Restore Backup" from the Summary screen. Choose the backup that contains your deleted contacts.


Use a third-party tool: There are several third-party tools available that can help you recover deleted contacts from your iPhone. Some popular options include EaseUS MobiSaver, Dr. Fone, and Tenorshare iPhone Data Recovery. These tools usually require you to connect your iPhone to your computer and follow the instructions provided by the software.


It's important to note that if you don't have a backup or if the backup doesn't contain your deleted contacts, the chances of recovering them are very low. In this case, you may need to manually re-enter the contacts or ask the people who you had them to share their contact information with you again.
