T-Mobile is a group of mobile phone companies (all owned by Deutsche Telekom) that operate GSM and UMTS networks in Europe and the United States. The "T" stands for "Telekom". Most subsidiaries (companies) of Deutsche Telekom have names beginning with "T-" like T-Home and T-Online. T-Mobile also owns parts of mobile operators in Eastern Europe. Globally, T-Mobile has 101 million subscribers, making it the world's sixth largest mobile phone service provider by subscribers and the third largest multinational after the United Kingdom's Vodafone and Spain's Telefonica.
T-Mobile International has a large presence in eleven European countries: Austria, Croatia, Czech Republic, Germany, Hungary, Macedonia, Montenegro, the Netherlands, Poland, Slovakia and the United Kingdom as well as in the United States.
Deutsche Telekom recently tried to buy rival mobile network operator O2, but it was eventually bought by Spain's Telefonica.
As well as football kit sponsors for FC Bayern Munich, Ferencvárosi TC, The Blues City and Borehamwood, T-Mobile is also a sponsor of several sports events, some of which carry the company name.
