Context-aware and location-aware cellular phones and methods are described. In one embodiment, cellular phones are configured to wirelessly receive information that pertains to their current context or location. The phones then automatically use the information to modify one or more cellular phone behaviors, e.g. by turning the phone off, changing the ringer's pitch, or placing the phone in a vibrate mode. In one particular embodiment, various location types are defined and have associated attributes that define a desired cellular phone behavior. One or more transmitters at a location for which a behavior is desired transmit information that pertains to the location's class type. The cell phones can carry an association of class types and their behaviors so that when the phones receive the class type information, they can automatically adjust their behavior.
