With the ECT Ring Back Tone Application, mobile customers can choose various songs, jokes, or other sounds played to the person who calls them, while they also hear the familiar ring back tone. The service works regardless of who calls. All Sonera mobile phone customers can use the service. The new service including a complete demonstration of the web interface can be seen at www.soneraplaza.fi/mobiili/kuvataanet .

The Sonera Theme Music Service – or Tunnari in Finnish – is being offered at a monthly fee of EUR 1.90, with each ring back tone priced at EUR 1.95. The service comprises nearly 50 tunes of different types. All tunes acquired are automatically saved in a tone library from where they can be easily retrieved and used again. Mobile customers can set up to 20 caller groups, and every group may have a maximum of 30 fixed-line or mobile phone customers. Via the service’s web site, subscribers can also buy music and create and edit caller groups. Furthermore, they can send toll-free text messages to inform the people in their caller groups that a special ring back tone has been selected for them.
