A communications system allows special messages to be transmitted to a wireless device subscriber if certain conditions are met. Identification information authenticating the sender may be sent using an originating device, such as a personal computer with a modem. A location information generating device, such as the ANI generator in a telephone end-office connected by physical telephone wire (local loop) to the computer, generates location information. The identification information and location information are provided to a message platform. The message-platform establishes time of day and compares sender identification information, originating device location information, and time of day information to prestored values to determine whether a special prestored message should be sent. If a message should be sent, the message platform initiates message transmission. Message transmission can be initiated if appropriate sender identification and location information are not received within a specified time window. The personal identification information, location information, and time of day information are furnished by three different devices operating independently of each other.
