Booth Junkie can let your guests send their photo straight to their own phone by SMS or MMS, using your own Twilio account to send the message.
Setting it up
Open the Admin Panel and navigate to the Sharing tab, followed by the SMS tab, and enable the first toggle. See Customising the SMS settings for connecting your Twilio account and setting up the message template.
What guests see
Once enabled, guests are offered an SMS/MMS option after their photo is taken, alongside whichever other sharing methods you’ve turned on. They enter their number on the on-screen keypad, and the photo is sent as a link via the number configured on your Twilio account.
