ringtone download application that charges a fee from the user for
each ringtone downloaded. One way to accept payment is to use a
reverse billing phone number obtained from a wireless carrier. To
buy a ringtone, the user will write an ordinary SMS text message
that contains the ID of the ringtone he/she wants to buy and send it
to your SMS application's reverse billing phone number. Your SMS
application will then send back one or more reverse billing SMS
messages that carry the ringtone. The user will be charged a fee for
the reverse billing SMS messages he/she received. The fee will be
included in the user's monthly mobile phone bill or be deducted from
his/her prepaid card credits. Depending on the agreement between you
and the wireless carrier, all or part of the money received will be
given to you.
