Business activities
With over 273 million mobile customers, more than 24 million fixed-network lines, and more than 22 million broadband customers, we are one of the leading integrated telecommunications companies worldwide. We provide fixed-network/broadband, mobile, internet, and internet-based TV products and services for consumers, and information and communication technology (ICT) solutions for business and corporate customers. We have an international focus and are represented in more than 50 countries. With some 200 thousand employees worldwide (as of December 31, 2025), we generated revenue of EUR 119.1 billion in the 2025 financial year. 78.0 % of the Group’s net revenue is generated outside of Germany.
Our mobile communications business offers mobile voice and data services to consumers and business customers. In addition, we sell mobile devices and other hardware. We also sell mobile services to resellers and to companies that buy network services and market them to third parties (mobile virtual network operators). Our fixed-network business includes all voice and data communications activities based on fixed-network and broadband technology. This includes the sale of terminal equipment and other hardware, as well as the sale of services to resellers. Drawing on a global infrastructure of data centers and networks, we operate ICT systems for multinational corporations and public-sector institutions.
Our ambition is to become the Leading Digital Telco. In pursuit of this, we are driving the responsible digital transformation of our Company and leveraging the potential offered by our data and by AI. This applies both to internal processes, so as to further enhance quality and efficiency, and to specific offerings to our customers. As a global Group with a large footprint in Europe and the United States, we are ideally positioned for this. The operation and sale of convergent networks remains our core business. Sustainability forms an integral component of the Group’s strategy, and as such is systematically and organizationally embedded in our business model and our company culture.
