A method and apparatus for downloading tone data from a public land mobile network to a mobile telephone unit is disclosed.

The downloaded tone data is uniquely associated with a selected telephone number within the mobile telephone unit such that a call to the mobile unit involving the telephone number initiates audio play back of the tone data.
