From this company link www.facebook.com/sscnig running a promo to setup short code for Nigerians as against N250k upwards.

This is what it means for people who do not understand.

Lets use a live example:
Who Wants To Be a Millionaire

How do you participate? You send a word to a four or five digit number for N100. Lets assume 300,000 people around Nigeria and outside wants to be a millionaire every week. Those N100 becomes N30million. So how much do they give out to weekly winners? Minus that from the N30million revenue generated per week?
Thats the business.

Same with Big Brother when you send a special SMS to choose your favorite housemate. Same with Guinness etc and all other TV, Radio programs.

Now this shortcode which is the four or five digit number is what you can now get for free once you register.
