Abstract
A method and apparatus for downloading tone data from a public land mobile network to a mobile telephone unit is disclosed. A mobile telephone unit includes means enabling the user to request downloading of tone data to the mobile telephone unit from a public land mobile network via a connection-less communications link such as the USSD or SMS. 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.
