In my experience many adults (meaning everyone over 35 at this point) seem to have an irrational attachment to phone calls, when texting or email would suffice or be better. This is just a manifestation of that mentality. If you encourage your kid to text you it's much more likely they'll communicate, largely because it can be done quickly and discreetly.

Given the problems I've heard about with app store purchases from parents in this target market there's zero chance of this actually working, and I'd be surprised if any parent in the target group even believes it would work either.
