Answer 2

USSD Callback is a service that allows user to send a "call me" request at no charge, via USSD protocol (that is the means used by the operator). For example, you ran out of credit and you want somebody to call you, the other person will pay the call. I hope this clarifies http://www.leibict.com/english/products/...
