Ringback tones allow mobile phone subscribers to replace the usual"ring, ring" sound that callers hear with the latest music hits, soundclips and other media chosen by the subscriber. Ringback servicesfirst gained popularity in Asia, where they're now ubiquitous, andhave rapidly gained momentum across Europe and the United States asmore and more callers experience this new service through the music orsounds their friends have chosen for them to hear.

Every mobile customer,regardless of handset, can use the ringback tones service, and all oftheir callers, regardless of whether they're calling from a fixed-lineor mobile phone, will hear the ringback that the customer has chosenfor them to hear. What the caller hears depends on the personalringback profile previously chosen and set by the Vodafone customer.The service allows customers to set their choices depending on who iscalling and when. Ringback preferences may be set easily via Web, SMS,IVR and the Vodafone live! portal.
