A system and method for anonymous exchange of multimedia content over a wireless network. Aliases are associated with users. A user sends a message which includes some non text content to another user by inserting the recipient's alias in the body of the message. The user then indicates a short code of an exchange server as the desired destination of the message. The message is routed to the exchange server through wireless network infrastructure. The exchange server parses the body to obtain the recipient alias. The exchange server then performs a database query to obtain a recipient phone number based on the recipient alias. The exchange server then sends the message to the recipient phone number. Also disclosed is the anonymous sending of messages by using long codes and buddy list indexes. Messages may also be sent or received by an Internet connected user.
