What if I can't find the address book in my mobile phone? How to restore my address book?

1. Now most smart phones have cloud account function, and mobile phone users can recover lost mobile phone contacts through cloud account.

Android phone users need to open the settings application and click the cloud account tab. Different phones will be in different locations, or there will be an avatar on the settings application. This avatar is the cloud account. Mobile phone users log in to the cloud account in advance, and the mobile phone will automatically back up the mobile phone address book, calendar, SMS, etc.

When the contact of the mobile phone user is lost, you can click the data recovery button in the cloud account to recover the mobile phone contact.

2. Apple mobile phone users have more ways to restore contacts. You can use iCloud, iTunes and ApowerRescus data recovery software to recover their contacts.

Apple mobile phone users can log on to iCloud website, where they can see iCloud cloud, and click iCloud cloud to find contacts to recover. You can also use ApowerRescus data recovery software to check the address book, and then click Start Scan. After scanning, you can restore the address book.
