Whether using the fixed or mobile network, whether at home or on the go: Deutsche Telekom offers consumers and business customers everything from a single source - in Germany under the "T" brand.

Through the integration of the service portfolio under the "T" corporate brand, Deutsche Telekom is able to meet the requirements of modern telecommunications customers in the consumer and business sectors in Germany. Telekom Deutschland GmbH is a subsidiary of Deutsche Telekom AG and is responsible for serving consumers as well as small and medium-sized enterprises (SMEs). T-Systems provides corporate and business customers with integrated solutions for connected business and society.

Telekom Deutschland GmbH

Mobile Internet, the connected home, cloud services and intelligent networks for the energy, healthcare and automotive segments are among the innovation and growth markets served by Telekom Deutschland. Deutsche Telekom aspires to be No. 1 - or in the words of its customers: "My first choice for connected life and work".

  • Core business: Fixed-network and mobile telephony, broadband Internet and TV products and services
  • Stake held by DT (indirectly/directly): 100.00 percent
  • Customers: 20.2 million fixed-network lines, 12,6 million retail broadband lines, 2.47 million TV customers and 40 million mobile customers (as of December 31, 2015)
  • Employees: 68,638 (as of December 31, 2015)


  • With its "network of the future," which will be completely based on IP technology by 2018, Telekom Deutschland GmbH provides state-of-the-art line technology.
  • And in late 2014, Deutsche Telekom launched the new turbo Internet known as "MagentaZuhause Hybrid" in Germany, again combining the fixed and mobile networks via a new Speedport hybrid router. It integrates the strengths of fixed DSL/VDSL network with modern LTE mobile technology. This considerably speeds up communications for customers with rather small bandwidths in the fixed network.
