Deutsche Telekom established T-Mobile International AG in 1999 to manage its mobile communications subsidiaries. From 2003 to 2007, T-Mobile International was part of Deutsche Telekom’s services, alongside “Broadband/Fixnet,” “Business Customers,” and “Group HQ and Shared Services.” In 2009, Deutsche Telekom restructured and merged T-Mobile International into Deutsche Telekom AG, creating integrated local businesses by combining its previously separate fixed and mobile subsidiaries.
While T-Mobile International AG existed, it was based in Bonn, Germany, and its subsidiaries operated GSM-, UMTS-, and LTE-based cellular networks in Europe, the United States, Puerto Rico, and the U.S. Virgin Islands. The company had financial stakes in mobile operators in Central and Eastern Europe. T-Mobile International’s subsidiaries had approximately 230 million subscribers worldwide, making it the world’s thirteenth-largest mobile-phone service provider by subscribers and the fourth-largest multinational after Vodafone in the UK, Airtel in India, and Telefónica in Spain.
