You should provide a demo of the service or even allow users to trail the site without having to enter any information to sign up. I will never enter a phone number or email until I'm satisfied with the product. I have no idea how it will work or what I am getting.
I agree. I wouldn't need to try it, but a good promotional video on the front page showing how it works and the UI after you sign up would be good. Add in the pricing at the end as well. What's free, what are the limits and how much it costs after that.
