T-Mobile International AG is a holding company for Deutsche Telekom AG's various mobile communications subsidiaries outside Germany. Based in Bonn, North Rhine-Westphalia, Germany, its subsidiaries operate GSM, UMTS and LTE-based cellular networks in Europe, Canada, the United States, Puerto Rico and the US Virgin Islands. The company has financial stakes in mobile operators in both Central and Eastern Europe.
The T-Mobile brand is present in 11 European countries – Austria, Croatia, Czech Republic, Germany (as Telekom), Hungary, Republic of Macedonia, Montenegro, the Netherlands, Poland, Slovakia and the United Kingdom, as well as the United States, Puerto Rico and the US Virgin Islands.
Globally, T-Mobile International subsidiaries have a combined total of approximately 150 million subscribers, making the company the world's seventeenth-largest mobile-phone service provider by subscribers and the third-largest multinational after the UK's Vodafone and Spain's Telefonica.
Germany's initial mobile-communications services were radiotelephone systems that were owned and operated by the state postal monopoly, Deutsche Bundespost. It launched the analog first-generation C-Netz ("C Network", marketed as C-Tel), Germany's first true mobile phone network in 1985.
On July 1, 1989, West Germany reorganized Deutsche Bundespost and consolidated telecommunications into a new unit, Deutsche Bundespost Telekom. On July 1, 1992, it began to operate Germany's first GSM network, along with the C-Netz, as its DeTeMobil subsidiary. The GSM 900 MHz frequency band was referred to as the "D-Netz", and Telekom named its service D1; the private consortium awarded the second license (now Vodafone Germany) chose the equally imaginative name D2.
Deutsche Bundespost Telekom was renamed Deutsche Telekom in 1995, and began to be privatized in 1996. That same year, DT began to brand its subsidiaries with the T- prefix, renaming the DeTeMobil subsidiary T-Mobil.
In 2002, as DT consolidated its international operations, it anglicized the T-Mobil name to T-Mobile.
On April 1, 2010, the T-Home and T-Mobile German operations merged to form a new wholly owned DT subsidiary, Telekom Deutschland GmbH. The T-Mobile brand was discontinued in Germany and replaced with the Telekom brand. The T-Mobile brand is still used in markets outside Germany. Non-German mobile-network assets are organized into various country-specific subsidiaries under the T-Mobile International AG subsidiary of DT.
In 2010, T-Mobile UK became part of a joint venture with France Telecom's UK mobile-network provider, Orange UK. Combined, the two companies make the UK's largest mobile-network operator, called EE. Despite the joint venture, the T-Mobile and Orange brands continue to co-exist in the UK market.
The T-Mobile brand is present in ten European countries – Austria, Croatia, Czech Republic, Hungary, Republic of Macedonia, Montenegro, the Netherlands, Poland, Slovakia, and the United Kingdom – as well as the United States, Puerto Rico, and the US Virgin Islands.
Globally, T-Mobile International subsidiaries have a combined total of approximately 150 million subscribers, making T-Mobile International the world's tenth-largest mobile-phone service provider by subscribers and the fourth-largest multinational after the UK's Vodafone, India's Airtel, and Spain's Telefónica.
