The cellco under Telefonica launched the value added service “between tones”, to allow clients to tailor their devices in choosing the waiting tone people listen to when calling. On launching, Movistar will offer eight tones and two months of service fees for free. "Between Tones" enables exchanging ringtones with other clients, either using the service or not, and the set-up of melodies for specific dates such as birthdays or national holidays, among others.
