  10. Launch the "Contacts" app on the Vigor
  11. Press "Menu" > "Import / Export", browse for the VCF file, select an account if necessary and load the file to your phonebook

NOTE: Alternatively, the vCard file can be transferred from the Galaxy SIII over to the LG G3 Vigor by connecting both smartphones to a computer via USB, and manually copy > pasting the file from one phone's storage to the other

Using "Send Anywhere":

NOTE: Send Anywhere is a third party application that can be used to transfer files and contacts over a peer-2-peer connection, thus a computer is not necessary. To use this method:

  1. Visit the Google Play Store and install "Send Anywhere" on your smartphones
  2. Open the app on both handsets
  3. On the Galaxy SIII, tap "Send" > "Contacts"
  4. Select the contacts you want to transfer and tap "Send"
  5. Finally, select the desired transfer method. Tapping "Generate QR Code" on the Galaxy SIII allows you to create a code which can be scanned with the LG G3 Vigor's camera to begin the transfer. You can also tap "Receive" on the LG G3 Vigor, and enter the randomly generated transfer code from the Galaxy SIII
