A method and system for filtering unwanted wireless telecommunications includes structure and steps/function for monitoring traffic associated with roaming subscribers, the traffic being carried via inter-network Internet Protocol links. Structure and steps/function are also provided for intercepting a send-routing-information message from an originating node within the traffic, and initiating a response to the originating node so as to direct the originating node to send a short message service (SMS) or Multimedia Messaging Service (MMS) associated with the send-routing-information message to a SPAM-filter via an SMS or MMS delivery message. Structure and steps/function are further provided for receiving the SMS or MMS at the SPAM-filter, and determining, at the SPAM-filter, whether the SMS or MMS constitutes an unwanted message. Also, structure and steps/function are provided for invoking an action for managing the SMS based on results of the determining process.
