T-Mobile is a mobile network operator headquartered in Bonn, Germany. It is a subsidiary of Deutsche Telekom and belongs to the FreeMove Business alliance.


T-Mobile is a group of mobile phone corporate subsidiaries (all under the ownership of Deutsche Telekom) that operate GSM and UMTS networks in Europe and the United States. The “T” stands for “Telekom.” T-Mobile also has financial stakes in mobile operators in Central and Eastern Europe. Globally, T-Mobile has 128.3 million subscribers, making it the world’s seventh largest mobile phone service provider by subscribers and the third largest multinational after the United Kingdom’s Vodafone and Spain’s Telefónica. T-Mobile USA is the fourth largest wireless telecommunications network in the U.S. market with 32.1 million customers after Verizon Wireless, AT&T Mobility, and Sprint Nextel.

T-Mobile International has a substantial presence in eleven European countries (Austria, Croatia, Czech Republic, Germany, Hungary, the Republic of Macedonia, Montenegro, the Netherlands, Poland, Slovakia, and the United Kingdom) as well as in the United States.

In late 2005 Deutsche Telekom attempted to acquire rival mobile network operator O2, but was beaten out by Spain’s Telefónica[1].

In March 2008, the company announced they planned to acquire Siemens Wireless Modules (now known as Cinterion Wireless Modules) as part of the JOMA consortium. The Siemens Wireless Modules spin off to Cinterion Wireless Modules was concluded on May 1, 2008.
