iPhone Data Recovery offers 3 modes to retrieve lost or deleted contacts for whatever reason. Each mode requires only 3 easy steps to restore lost contacts (address book) from iPhone 7/7 Plus/SE/6s Plus/6s/6 Plus/5s/5c/5/4s/4 as well as iPad and iPod series, no matter you have backed it up before or not.
Select Recovery Mode -> Scan iOS Device/Backup/Download Backup -> Preview and Recover
Run the program on your computer, and choose a suitable recovery mode from the interface. If you choose “Recover Data from iOS device” mode, you have to connect your iDevice to computer with a USB cable. If you want to retrieve data from iTunes or iCloud backup file, just switch to the corresponding section from the interface, without need of connecting device.
If you didn’t have iDevice files back up to neither iTunes nor iCloud, the program allows you to recover lost files from iPhone, iPad and iPod directly without any backup.
Connect iDevice to computer via USB cable >> Tap “Trust” on device when pop-up window appears >> click “Start Scan” to scan all contacts in your device.
If you have no idea to connect device to computer for scanning, but luckily you had files backed up to iTunes before, this feature enables you to recover lost data from iTunes backup effortlessly.
Click Recover from iTunes backup files in the interface > Select one backup file stored lost data > Click “Start Scan.”
If your iDevice is neither unhandy or unworkable due to stolen, water-damaged, stuck, etc, nor didn’t you back up to iTunes, you also are allowed to recover lost data from iCloud backup.
Manually log into iCloud account/Click Software Access to detect iCloud backup automatically > Choose an iCloud backup stored lost data > Click Next to move on
All the lost data is listed here. Click Contacts to display the items. After checking the detailed information, you can tick target items selectively you want to recover and then tap Recover button at the right bottom to retrieve data.
