Contacts Backup

Contacts Backup is a FREE application that allows you to back up the numbers of people saved on your phone to the excel file and restore the address and address of the person concerned to your phone as soon as you need them. You can email your excel file from your second option to your directory. You can edit any file you want on this file.
If your device changes or disappears, or if your contacts are deleted, you can protect your contacts from accidental loss by restoring the contacts backup you received from your application to your new device or contacts.
If you want to retrieve deleted contacts from the last saved file, you can also restore them to your phone by simply reloading them. In the process of retrieving, you need to download the file by e-mail and download the current file (transfer your contacts folder to your phone's download folder).
