1&1 AG
1&1 AG (known until 2 June 2021 as: 1&1 Drillisch Aktiengesellschaft) is a German telecommunications service and landline and mobile telecommunications provider headquartered in Montabaur, Rhineland-Palatinate and listed on the TecDAX. Since 2017, the majority of the company has belonged to United Internet.
At the end of 2021, 1&1 employed 3,167 people and reported revenue of 3.91 billion Euros by the end of the fiscal year. As of 31 December 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. 1&1 Mobilfunk's main competitors are Telekom Deutschland (Deutsche Telekom's German private customer unit), Telefónica Germany and Vodafone Germany.
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 50 MHz of spectrum in the 3500 MHz band and 2x10 MHz in the 2100 MHz FDD band. While the network was initially planned to start in 2021, it was later delayed.
A core requirement for 1&1's operations as a network operator is national roaming. The company initially signed a contract with Telefónica Germany in May 2021. However, in August 2023, 1&1 announced a surprise long-term roaming partnership with Vodafone Germany. This agreement was finalized in 2024, enabling 1&1 to use the Vodafone network in areas where its own network is not yet available. By mid-2025, 1&1 had successfully completed the migration of its existing customer base to its own network core.
The core business of mobile services is domiciled in the fully affiliated subsidiaries:
Under the brand names of the Drillisch subsidiaries, primarily mobile-services providers for private customers are marketed via the internet, and M2M products are marketed to businesses. For (a selection of) these products, the mobile networks of both Telefónica and Vodafone are utilized, whereby the products in the Vodafone network generally display a higher average price level than those of Telefónica. Private consumers comprise about 20% of the total business, and business guidelines for the subsidiaries mostly come from the company's central headquarters, meaning that most brands display a similarly structured tariff portfolio. As of 1 April 2014, all providers were introduced to a new tariff structure.
The Maintal subsidiary of Drillisch AG, IQ-optimize Software AG, operated under the name "IQ-work Software AG" until 29 May 2007, and primarily offers technical services for its parent company. To a lesser extent, the company offers similar services to other business clients. In addition to its technical services, IQ-optimize Software AG operates licenses for a "workflow management" software named "Mapito", which was developed in-house.
