If using a Google Android device:
1. While on the device that has all your contacts, go to your Contacts app -> Click on the 3 horizontal bars on the top left -> Click on Settings -> Click on Export -> Click "Export to .vcf file" and download the file locally on your phone.
2. Open whatever email application you use and send the file to yourself over email.
3. Once you have your email setup on the NEW Ghost phone, open your email and download the .vcf file you sent yourself. Open the file and it will auto-populate all your contacts within the Contacts app on the new device.

If using an iPhone, the process is similar to the above, however the navigation to export your contacts is different:
1. log into iCloud account from your computer and select all your contacts on the settings button (bottom left) it says Export vCard.
2. Click this and you can Export all your contact information as a .vcf file.
3. Open whatever email application you use and send the file to yourself over email. If you cannot send over email use whatever method you have available to move the .vcf file from your computer to your NEW Ghost Phone.
4. Once you have your email setup on the NEW Ghost Phone, open your email and download the .vcf file you sent yourself. Open the file and it will auto-populate all your contacts within the Contacts app on the new device within a few seconds, depending on how many contacts you have.
