The number of landline telephone connections in Germany experienced a drop in the last decade, arriving at its lowest point in 2014, but picking up again in later years, with an estimated 38.5 million connections existing in 2017. As of the same year, an estimated 21.5 million landline connections were VoIP via unbundled DSL, making it the most widespread connection type, while nine million were analog/ISDN (including public phones). The amount of outgoing call minutes per day from landline networks in Germany decreased significantly in the last twenty years, peaking at 586 million minutes in 2003, then dropping to an estimated 325 million daily minutes in 2018. A similar trend of falling numbers is visible in landline services revenue during the same period, peaking at 38.5 billion euros in 2005 and declining afterwards, amounting to an estimated 27.1 billion euros in 2018.
Meanwhile, the number of mobile phone connections in Germany, while fluctuating in some years, has generally experienced continuous growth, counting 134.7 million in the second quarter of 2018. In the same period, the most used provider was Vodafone (D2 network) with 46.5 million connections, followed by Deutsche Telekom (D1 network) with 43 million connections. In 2017, mobile data volume usage amounted to 1.39 billion gigabytes, a big jump compared to 913 million gigabytes the year before. The number of smartphone users in Germany mushroomed in the last decade, from 6.3 million in 2009 to 57 million 2018.
So far, the number of broadband internet connections has also only increased during the millennium, from 1.9 million DSL in 2001 to almost 25 million in 2017. The average internet speed in Germany amounted to roughly 15,2999 Kbit/s.
