Abstract: Systems and methods for filtering cellular messages to prevent receipt of certain messages are described. In one aspect, a computing device detects an incoming cellular telephone message for delivery to a receiver. The device filters the message by determining source identification information for the incoming cellular telephone message. The device compares this information to source identification entries in an acceptable senders list. The acceptable senders list includes source identification information corresponding to previous incoming and outgoing voice contacts by the receiver. If the source identification information for the incoming cellular telephone message is not found in the source identification entries in the acceptable senders list, the device deletes the cellular telephone message from a memory to prevent receipt of the message by the receiver.
