Since 2017, the majority of the company has belonged to United Internet, and offers both mobile and landline services. At the end of 2021, 1&1 employed 3,167 people and reported profits of 3.91 billion Euros by the end of the fiscal year. As of December 31, 2021, 1&1 had about 15.4 million customer contracts, 11.2 million of which were for mobile services and 4.2 million for broadband internet. For its mobile services, the company relies on the network infrastructures of Telefónica Germany (all brands) as well as that of Vodafone Germany (1&1 brand). Due to the requirements of antitrust authorities regarding the merger between E-Plus and Telefónica, Drillisch was able to secure 30% of Telefónica's network capacity. Historically, the company relies on the networks of other providers as well as its own 1&1 Versatel network for its DSL (Digital Subscriber Line) and fiber-optics services. With 1&1 Versatel, its parent company, United Internet, owns its own landline infrastructure operates more and more customer connections with its own broadband supply. In the sale by auction of 5G frequencies in 2019, the company received the bid for the construction of its own mobile network. Drillisch acquired with 50 MHz of spectrum in the 3500 MHz band and 2x10 MHz in the 2100 MHz FDD band. Its network is slated to begin operation at the start of 2021. A basic requirement to begin work as a network operator is national roaming, for which 1&1 received an improved offer from Telefónica in October 2020 following assessment by the European Commission. At the end of May 2021, the offer was converted into a contract.
