Recover deleted call history

Hey there, and welcome to Apple Support Communities Apelsin1992,

We can certainly understand your concern and can help provide some insight.

In order to recover missing data from your device, you will need to restore your iPhone from a recent backup before the data was deleted. Please keep in mind that all new information created after the save point will be lost. Check out this link on how to restore your iPhones data.

" Restore iPhone from an iCloud backup

1. Turn on a new or newly erased iPhone.
2. Do one of the following:

• Tap Set Up Manually, tap Restore from iCloud Backup, then follow the onscreen instructions.
• If you have another iPhone, iPad, or iPod touch with iOS 11, iPadOS 13, or later, you can use Quick Start to automatically set up your new device. Bring the two devices close together, then follow the onscreen instructions to securely copy many of your settings, preferences, and iCloud Keychain. You can then restore the rest of your data and content to your new device from your iCloud backup.
  • Or, if both devices have iOS 12.4, iPadOS 13, or later, you can transfer all your data wirelessly from your previous device to your new one. Keep your devices near each other and plugged into power until the migration process is complete.

You’re asked for your Apple ID. If you’ve forgotten your Apple ID, see the Recover your Apple ID website.
