Extend your campaign to the phone by including an option for viewers to send an automated SMS message or voicemail message. With SMS messaging, you can give users the option to enter a mobile phone number for themselves or a friend to get text reminders about a show, movie, product or service. With voicemail, you can give users the option to enter a phone number to get a greeting from a celebrity or other compelling audio content. This is a great way to extend your campaign to a viewer's most personalized device, the phone.
