A spam filtering system and method are disclosed for filtering spam destined for a mobile communication device. In the spam filtering system, a processing system receives a message destined for a mobile communication device through an interface. The processing system processes the message based on first filtering criteria to make an initial determination whether the message is suspected of comprising spam. If the processing system determines that the message is not suspected of comprising spam, then the processing system transmits the message to a message center. If the processing system determines that the message is suspected of comprising spam, then the processing system processes the message based on second filtering criteria to make a final determination whether the message comprises spam. If the processing system determines that the message does comprise spam, then the processing system blocks the message.
