Here’s a couple of nice options that may not be well known. You can share a contact by visiting the contact card in iOS and using the share sheet to send it as a text message. The shared contact can then be added, in its entirety, by the recipient on their iOS device.1
Maybe even more obscure than sharing a contact card, is sharing a voice message from iOS. While the message is selected for playing, tap the share icon in the upper right corner of the message. Now you can send the m4a audio to someone else by text message or even save it in your DEVONthink reference folder like I do.
Don’t worry, that number is Verizon spam. They’re clearly lonely for human contact so I figured sharing it was no real harm. ↩︎
