Using "My Contacts Backup":

NOTE: The methods explained above require access to a computer, but you can easily transfer your contacts without one, with the help of various third party apps. My Contacts Backup is an iOS application that can be used to back up your contacts as a VCF file, and transfer it via email. To do so:

  4. Send the email to your Gmail address
  5. On the LG G3 Vigor, open the email and download the attached VCF file
  6. Open the "Contacts" app and use the "Import" option to import the VCF file's contents

Using "Send Anywhere":

NOTE: Send Anywhere is a third party app for iOS and Android, which can be used for transferring contacts and other types of files cross-platform, through a p2p connection. To perform this method:

  1. Go to the Google Play Store and install "Send Anywhere" on the LG G3 Vigor
  2. From the App Store, install the same app on your iPhone
  3. After the app is installed, launch it on both smartphoens
  4. On the iPhone, tap "Send" > "Contacts"
  5. Mark the contacts you want to transfer and then tap "Send"
  6. Finally, select the desired transfer method. Tapping "Generate QR Code" on the iPhone generates a code that can be scanned with the Vigor's camera to commence the transfer process. You can also tap "Receive" on the LG smartphone, and enter the randomly generated transfer code from the iPhone
