Know of any good examples of account validation using SMS (a la Twilio's SMS API)?

I'm working on a flow for starting a free trial for a paid product. We're exploring using a phone number (SMS them a code, they enter the code on our site) to validate the user as unique. What are your thoughts on this approach? Are you familiar with products or services that use this? Any that use it with particular success? How would that compare with something like using Facebook authentication?
