Philosophy: Mobile freedom

With this thought Markus Haas has set a standard in the industry: Thanks to Telefónica Germany, people can use the achievements of digitization anytime and anywhere - in a way that suits their individual wishes, preferences and habits. In order to continue on this path consistently, Telefónica Deutschland will become the Mobile Customer and Digital Champion by the end of 2022. The trampoline for this and for further progress in digitalisation is a powerful telco network. We will therefore be making additional investments in the three-digit million range - an investment programme that is unique in this amount for the company. With the determined 5G rollout, Markus Haas and Telefónica Deutschland are making a decisive contribution to shaping Germany's sustainable digital future.
