Need to quickly transfer contacts to an iPhone without using iTunes or connecting the iPhone to a computer? The easiest way to do this is by emailing a vCard file containing all the contacts to the phone, these .vcf files can be exported from many other phones, another iPhone, Address Book, Google and Gmail, Yahoo, and just about anywhere else you’d store contact information.
You’ll probably want to backup and sync the iPhone beforehand just in case something goes haywire importing the vCard, however unlikely that is.
From a computer where the contacts are stored, create a new email with the vCard attachment and send it to yourself (or rather, the email on the iPhone)
Open the email containing the contacts on the iPhone and tap on the vCard.vcf file attachment
Tap on “Add All # Contacts” to import the address book to the iPhone
Notice the add option tells you how many contacts are stored within the vCard, making it easy to determine if all intended contact information is included. You can also manually select individual contacts from the list if you only wish to import one or two, but for the purpose here we’ll transfer them all over.
Verify that the address book was moved over by launching either Phone and tapping Contacts or by launching the separate “Contacts” app on the iPhone.
What if the contacts are saved as a CSV file instead of VCF vCard?
Most apps and services will export as a VCF but if you wind up with an exported .CSV file, you can use a CSV to vCard converter tool to bring them over into a compatible vCard format. Here is a free online converter that will do this, just paste in the CSV, copy the vCard data into a text file, and save with a .vcf extension.
