Yes, you can. Keep in mind that the way you can share your digital card through text message is different for digital cards than it is for invitations. Instead of adding phone numbers to the recipient page, you'll want to copy the direct link to the card and paste it into your text message. To generate a direct link to a digital card, locate the card on your dashboard.
If you haven't sent your card yet, click the green "Send" button.
If you have already sent the card out, you'll want to click the "Add Recipients" button and navigate to the Send
On the Send page, you will see options to share the card through Facebook Share, Twitter, and a Link button that creates a direct URL link to the card. Click the "Link" button and you will see a popup with the URL that links to your card which you can copy and paste into a text message.
