Premium SMS Number
A Premium SMS number is a 3-7 digit number. The user is billed a premium price to the end user per sent SMS which is higher than for a normal P2P message. Depending on the market that cost can be from twice as high to even fifty times higher.
One of most known use case for premium SMS is when the numbers are used for charity or voting projects e.g. when a natural catastrophe happens, users can easily send an SMS message to a short code in order to donate funds to help people in need.
Another use case is linked with reality show voting where shows like Big Brother or Voice usually have contestants competing for a grand prize. The show’s viewers can vote and contribute to their favorite contestant success.
Retailers also use premium SMS numbers to give worthless awards like a car or exotic trip.
