  • Shares held by DT (indirectly/directly): 100.00 percent
  • Customers: 4,595 million (as of December 31, 2016)
  • Employees: around 1,300 (as of December 31, 2015)


  • In September 2014, T-Mobile Austria launched a new modular rate plan structure based on the “Wie-Ich-Will-Prinzip (Just-the-way-I-want-it principle)”, whereby the rate plan and the smartphone are billed separately. Furthermore, JUHU! was introduced, which allows users to upgrade their phone every year. T-Mobile teamed up with Netflix in February 2015, to become Austria's first mobile operator to provide its WOW-video streaming service ("The programs I want, when I want them") on the LTE network; T-Mobile also started buying back used mobile phones and tablets.
  • The year 2015 marked a rapid expansion of LTE at T-Mobile, with around 50 new LTE stations being connected to the network every week. As a result more than 2.000 stations were added to the network. Because of this roll-out, T-Mobile was able to offer mobile broadband to nine out of ten Austrians by the end of 2015. The goal is to cover more than 95 percent of the Austrian population with LTE by the end of 2016. Adding to this success story is the fact that T-Mobile is running a complete CO2-neutral network since the beginning of 2015.
  • Since March 2016, the first sustainably produced smartphone in the world, the Fairphone 2 is available together with a contract in Austria. As the first Austrian mobile operator and one of the first mobile operators in the world, T-Mobile was launching a long-term partnership with the Dutch company Fairphone and is offering the Fairphone 2 to all its new and existing customers.
