It is questionable whether people foolish enough to vote via SMS should be considered competent enough to vote in the first place.
But then it is the failure of due diligence of educational system to teach from an early age how democracy works and how to participate in it.
People are trained to be doctors, lawyers, technologists etc, but the basic social skill of participating in democracy is not taught, when in fact it is the most important skill.
That and money management skills.
