How does Premium SMS work? What is the meaning of MO/MT messages?
The Premium SMS process: the customer sends a message (for example HORO TWINS) to a shortcode (for example 3010). This is called a MO message. The SMS service will respond by sending a reply to the customer, for example todays horoscope. The reply is called a MT message. The MT message will be charged to the customers phone bill by the operator.
