How can I recover deleted phone numbers on iPhone?

To recover deleted phone numbers (contacts) on your iPhone, you can either restore from a recent iCloud backup or, if you've recently deleted them, check the "Recently Deleted" folder in the Contacts app. 

Here's a breakdown of the methods:

1. Restoring from iCloud Backup:

• If you have iCloud backups enabled: You can restore your iPhone from a backup made before the contacts were deleted. 
• Go to iCloud.com: In a web browser, log in to your iCloud account. 
• Select Data Recovery: Click on the App Launcher button, then under "More" choose "Data Recovery". 
• Select Restore Contacts: From the data recovery page, select "Restore Contacts". 
• Select the date before you deleted the content: Scroll down to the bottom of the window, then select Data Recovery, then select Restore next to the date before you deleted the content 

2. Checking the "Recently Deleted" Folder:

• Open the Contacts app: On your iPhone, open the Contacts app.
• Go to Groups: Tap on "Groups" and select "Recently Deleted".
• Recover Contacts: Select the contacts you want to recover and tap "Recover". 

3. Other Considerations:

• Deleted Contacts are Permanently Deleted:
• If you delete a contact from your email account, it's permanently deleted from all devices signed into that email account. 
• Deleted Call History:
• To recover a deleted call history, restore your iPhone from a backup you made before the data was deleted. 
• Deleted Messages:
• You can restore messages you deleted for up to 30 days. Go to the Messages app, tap Edit, then tap Show Recently Deleted.
