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. As of 2017, 21.5 million landline connections were VoIP via unbundled DSL, making it the most widespread connection type. The amount of outgoing call minutes per day from landline networks in Germany decreased significantly in the last twenty years, peaking at 516 million minutes in 2003, then dropping to an estimated 293 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 27 billion euros in 2018.
Meanwhile, the number of mobile phone connections in Germany, while fluctuating in some years, has generally experienced continuous growth, counting almost 137 million in 2018. In the same period, the most used provider was Vodafone (D2 network), followed by Deutsche Telekom (D1 network). In 2018, mobile data volume usage amounted to 1.99 billion gigabytes. 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 25 million in 2018.
