Jamba! was founded in August 2000 as joint enterprise for mobile Internet between debitel, Media-Markt/Saturn and EP:ElectronicPartner. Its aim is to become the leading portal for mobile Internet in Germany and Europe.

EXCELSIS has developed a ring tone application which allows the listening to, selection and ordering of mobile phone ring tones with natural speech dialogue over the phone.

"The chance to listen to our ring tones and order them over the phone provides our customers with an additional service they can use anywhere, no matter where they are. For our company, the telephone is the most important channel to our customers."
