Claim:
A method for enabling a user of a mobile device to purchase a Ring Back Tone (“RBT”), the method comprising steps of: receiving an identifier associated with the mobile device that has received the RBT as a result of a call to another device and a mapping identification code associated with a RBT content identification code; generating a long code for the mapping identification code; generating a message with the long code as a reply-to-number; sending the message to the mobile device, the message offering the user of the mobile device an option to purchase the RBT; receiving a text-message response sent from the mobile device to the reply-to-number included in the message; determining that the received text-message response reflects the mobile device's user desire to purchase the RBT based on the text-message response having been sent to the reply-to-number included in the message; identifying the mapping identification code from the reply-to-number in the response; and upon determining that the user desires to purchase the RBT from the response, allowing the purchase of the RBT by determining the RBT content identification code based on the mapping identification code.
