As service provider, debitel works together with four network operators, D1, D2, E-Plus and Quam. It will also cooperate with these partners for the launch of the UMTS standard. In addition to mobile telephony, debitel offers fixed-network and Internet services. In 2000 the company reported revenues of CHF 4 billion, which accounts for over 30 per cent of total Swisscom revenues. Debitel also operates in France, Holland, Denmark and Slovenia.
When Swisscom took over as majority shareholder in July 1999, debitel had a customer base of 3.7 million. The transaction represented Swisscom´s biggest ever investment in another company.
