With the 123 Contacts Backup And Transfer app you can easily export & import your mobile phone contacts in a file that's easy to edit, print, share with other applications or simply keep it for future use. You can also use the app to transfer your contacts between two phones. e.g. when you buy a new smartphone (Android, iPhone) and want to import your contacts from the old one. The same of course can happen if you lose your mobile phone and you want to restore your contacts from an older file copy.
