Deutsche Telekom AG, often known simply as Deutsche Telekom or DT, is a German telecommunications company with its headquarters in Bonn. It is the largest telecommunications provider in Europe by revenue. The company was formed in 1995 following the privatisation of Deutsche Bundespost, a state monopoly at the time. The first German mobile network was launched by Deutsche Bundespost Telekom in 1985 based on analog (1G) technology under the C-Tel brand. To operate its mobile services division a subsidiary was created in 1992 known as DeTeMobil. The brand did not last long, with its name changed to T-Mobil in 1996 (and later T-Mobile in 2000) which remained until 2010 when the network became known simply as Telekom.
The German government holds a significant stake in the company, with a direct 14.5% of company stock and an additional 17.4% through the government bank KfW as of April 2020. Deutsche Telekom is a component of the EURO STOXX 50 stock market index. The company was originally the monopoly Internet service provider (ISP) for Germany until its privatisation in 1995 and has remained a dominant ISP in the country.
3G Network
2G GSM services were launched in July 1992 over 900 MHz, and later introduced 1800 MHz. 3G UMTS services became active March 2006 over the B1 (2100 MHz) band, and later upgraded to HSPA+ in April 2010 and DC-HSPA+ in 2011. The network has since been shut down.

4G Network
Telekom's 4G LTE service began in April 2011 with a B20 (800 MHz) network, and very shortly after also on the B3 (1800 MHz) and B7 (2600 MHz) bands. A 300 Mbps LTE-Advanced network was implemented November 2014 using 2C CA_3A-7A. 3C aggregation was trialled and achieved 375 Mbps by combining its 10 MHz B20 carrier (CA_3A-7A-20A). LTE-A Pro was demonstrated in September 2016, achieving 1.2 Gbps using 5C aggregation and 4X4 MIMO. Further LTE carriers were rolled out during 2017 to improve capacity.
NB-IoT was first launched NB-IoT on its Berlin network in October 2016 initially as a demonstration network, later expanded in March 2017 following the company's B8 (900 MHz) rollout. In November 2018 Deutsch Telekom announced its intention to deploy an eMTC LTE-M network in mid 2019 to support higher data rate IoT applications up to 1 Mbps. LTE-M testing has been conducted at labs in Berlin and Reutlingen throughout 2018.

5G Network
Achieving a European and arguably world first, in May 2018 Deutsche Telekom announced the rollout of 5G base station antennas on its live network. The network operates over the n77 (3700 MHz) band, using spectrum granted by the Bundesnetzagentur under a testing licence. Telekom Deutschland secured 90 MHz of 3.5 GHz spectrum during the national spectrum auction conducted in June 2019. The network officially transitioned to a full commercial spectrum licence in September 2019, with 5G data rates up to 1 Gbps available in Berlin, Bonn, Darmstadt, Cologne and Munich, where 129 5G antennas are transmitting.
The company later added n1 (2100 MHz) as a DSS band in June 2020 and a dedicated n28 (700 MHz) carrier in June 2022. The entire network was upgraded to Standalone (SA) in September 2023.
