Deutsche Telekom with more than 100 million mobile communications customers and in a top position regarding new DSL customers Jan 28, 2007 In the 2006 financial year, continued to significantly increase its customer base in the domestic and international markets and thus improved its market position. Within Germany, the T-Com and T-Mobile rates, which were newly introduced last year, established themselves successfully on the market.

In the Broadband / Fixed Network area, T-Com again achieved a leading position regarding the acquisition of new DSL customers thanks to the new 3x3 bundled rates. The proportion of self-marketed broadband lines in the T-Com network increased in the fourth quarter to 64 percent from 19 percent in the third quarter of 2006. With 563,000 new broadband retail customers, T-Com recorded the highest quarterly increase for DSL since the broadband technology was launched on the market. Overall, the amount of 3x3 bundle packages sold at the end of the year increased to 3.6 million; more than two thirds of the packages were sold in the Double Play (telephone and Internet) area. Including Resale DSL, i.e. broadband lines marketed by competitors on the T-Com network, the amount of DSL lines increased in the fourth quarter by 878,000 to 10.3 million. T-Com was able to more than double the number of international broadband lines compared to last year to over 1.4 million.

As a result of the T-Mobile@Home calling plan introduced last spring, the Group was also able to benefit from continuing fixed network substitution: More than 1.1 million customers in Germany used this plan by the end of the year. In the mobile communications area, customer numbers increased to significantly more than 100 million through organic and inorganic growth. At the cut-off date, T-Mobile had 106.4 million customers, including the customers of PTC and those of tele.ring which was acquired in Austria. Adjusted for consolidation effects, customer numbers increased by 8.6 million or 8.8 percent.

In Europe, T-Mobile recorded strong inorganic growth as a result of the PTC consolidation in Poland and the acquisition of tele.ring in addition to the organic growth in the national companies. Overall, the amount of mobile communications customers in Europe increased by around 19.8 million customers or 22.9 percent in a year-on-year comparison. In Germany, T-Mobile recorded roughly 746,000 net additions in the fourth quarter, 384,000 of whom opted for a fixed-term contract. Internationally, significant customer growth was achieved primarily by T-Mobile USA: In the USA, T-Mobile recorded 901,000 net additions in the final quarter of 2006, 783,000 of whom are contract customers. At the end of the year, T-Mobile USA thus exceeded the 25 million customer mark.
