Press Release

T-Mobile USA

Bellevue, May 11, 2006

T-MOBILE USA REPORTS FIRST QUARTER 2006 RESULTS

• Over 1 million net new customers added in Q1 2006

• $1.1 billion in Operating Income Before Depreciation and Amortization (OIBDA) in Q1 2006, a 34% increase over Q1 2005

• Reduction in postpay churn to 2.1%, from 2.3% in the fourth quarter of 2005

• T-Mobile achieves top ranking in four separate J.D. Power and Associates surveys

• Continued investment in network quality – 3,700 new cell sites on air over the past 12 months

In the first quarter of 2006 T-Mobile USA added 1.04 million net new customers, up from 957,000 in the first quarter of 2005, and lower than the 1.39 million net customers added in the fourth quarter of 2005 primarily due to seasonal impacts. Postpay customers made up 70% of the first quarter customer growth, up from 66% in the fourth quarter of 2005, and comprised 84% of T-Mobile USA’s total customer base at March 31, 2006.

Postpay churn fell to a record low 2.1% in the first quarter of 2006, down from 2.3% in the fourth quarter of 2005 and the first quarter of 2005. Prepaid churn was 5.8% in the first quarter of 2006, compared to 6.6% in the fourth quarter of 2005 and 6.4% in the first quarter of 2005. Blended churn, including both postpay and prepaid customers, was 2.7% in the first quarter of 2006, down from 2.9% in the fourth quarter of 2005 and 2.8% in the first quarter of 2005.

“We started the year strong, adding over one million high quality new customers,” said T-Mobile USA President and CEO Robert Dotson. “T-Mobile customer loyalty also continues to increase, resulting in record low churn aided by the benefits of ever increasing network quality improvements – while continuing to reap the benefits of a 56% expansion in our coverage footprint last year.”

René Obermann, CEO of T-Mobile International and member of the Board of Management of Deutsche Telekom (NYSE: DT), stated, “T-Mobile USA again delivered strong results and is a key driver of growth for the mobile segment and Deutsche Telekom as a whole. Together with the U.S. business, T-Mobile International’s customer base is now approximately 88 million customers worldwide. Growing the business to this scale provides strong leverage in terms of both size and expertise to compete effectively in the wireless market.”

T-Mobile USA’s commitment to achieving excellence in all facets of the customer experience was again recognized during the quarter in four separate J.D. Power and Associates surveys. T-Mobile USA ranked highest in overall customer satisfaction among wireless carriers for the third consecutive reporting period, achieved highest ranking in Wireless Customer Care for the third reporting period in a row, was ranked highest, or tied for highest, in three of the six regions surveyed in the 2006 Wireless Call Quality Performance Study and earned highest honors for wireless retail service.

T-Mobile USA reported OIBDA of $1.10 billion in the first quarter of 2006, in line with $1.11 billion in the fourth quarter of 2005 and up from $826 million in the first quarter of 2005. T-Mobile USA’s net income for the first quarter of 2006 was $241 million, down from $2.99 billion in the fourth quarter of 2005 and up from $103 million in the first quarter of 2005. Net income in the fourth quarter of 2005

included a $2.6 billion non-cash income tax benefit from the recognition of net operating loss carry forwards.

T-Mobile USA service revenues, consisting of postpay, prepaid, roaming and other service revenues, were $3.39 billion in the first quarter of 2006, up from $3.26 billion in the fourth quarter of 2005 and $2.85 billion in the first quarter of 2005. Other revenues were $198 million in the first quarter of 2006, down from $213 million in the fourth quarter of 2005 and $252 million in the first quarter of 2005. Other revenues include Wi-Fi revenues, co-location rental income, and wholesale revenues from the usage of our network in California, Nevada, and New York by customers of Cingular Wireless LLC (“Cingular”). The sequential decrease in other revenues in the first quarter of 2006 reflects the ongoing migration of Cingular’s customers to their network following the dissolution of our network sharing venture in early 2005. Total revenues, including service, equipment, and other revenues were $4.04 billion in the first quarter of 2006, up from $3.95 billion in the fourth quarter of 2005 and $3.44 billion in the first quarter of 2005.

Average Revenue Per User (“ARPU” as defined in note 1 to the Selected Data, below) was $51 in the first quarter of 2006, down from $52 in the fourth quarter of 2005 and $54 in the first quarter of 2005. The sequential decrease in ARPU related primarily to the decrease in prepaid ARPU and the increasing share of prepaid customers in the total customer base.

Data services revenue from postpay and prepaid customers continued to grow, reaching a total of $341 million in the first quarter of 2006. Data revenues, which are a component of service revenues, represented 10.1% of blended ARPU, or $5.12 per customer, in the first quarter of 2006, compared to 9.1%, or $4.77, in the fourth quarter of 2005 and 6.9%, or $3.71, in the first quarter of

2005. A significant contributor to the growth in data services revenue was a net increase in converged device users of 107,000 during the first quarter of 2006. T-Mobile USA had over 1.2 million converged device users at March 31, 2006. Converged devices include BlackBerry, T-Mobile Sidekick, and the recently launched T-Mobile SDA and MDA devices. Continued strong growth in messaging (both SMS and MMS) also contributed to the increase in data ARPU. The total number of SMS and MMS messages increased to 6.9 billion in the first quarter of 2006, compared to 5.4 billion in the fourth quarter of 2005 and 3.6 billion in the first quarter of 2005.

The average cost of acquiring a customer, Cost Per Gross Add (“CPGA”, as defined in note 3 to the Selected Data, below) was $275 in the first quarter of 2006, up from $264 in the fourth quarter of 2005 and down from $357 in the first quarter of 2005. Compared to the fourth quarter of 2005 the increase in CPGA is primarily due to the seasonally lower gross additions in the first quarter versus the fourth quarter of the year.

The average cash cost of serving customers, Cash Cost Per User (“CCPU”, as defined in note 2 to the Selected Data, below), was $25.66 per customer per month in the first quarter of 2006, up from $24.32 in the fourth quarter of 2005, and down from $26.48 in the first quarter of 2005. The sequential increase in CCPU in the first quarter of 2006 was due to a number of factors, including increased customer retention spending and higher network operating expenses to support the expanded network.

Capital expenditures were $770 million in the first quarter of 2006, compared with $807 million in the fourth quarter of 2005 and $376 million in the first quarter of 2005. (Capital expenditures in the first quarter of 2005 excluded $2.5 billion of expenditures related to the acquisition of Cingular’s California network

and additional spectrum after the termination of the network sharing venture at the beginning of 2005.) As part of its ongoing commitment to network coverage and quality, T-Mobile USA added approximately 700 new cell sites in the first quarter of 2006, bringing the total number of cell sites to approximately 33,600.

Since all companies do not calculate these figures in the same manner, the information contained in this press release may not be comparable to similarly titled measures reported by other companies.

(1) Average Revenue Per User (“ARPU”) represents the average monthly service revenue we earn from our customers. ARPU is calculated by dividing service revenues for the specified period by the average customers during the period, and further dividing by the number of months in the period. We believe ARPU provides management with useful information to evaluate the recurring revenues generated from our customer base.

Service revenues include postpay, prepaid, and roaming and other service revenues, and do not include equipment sales and other revenues. Revenues from our Wi-Fi business,

co-location rental income, and revenues for network usage by Cingular customers who have not yet transitioned from the former joint venture networks in California, Nevada, and New York, are therefore not included in ARPU. The joint venture was terminated at the beginning of 2005.

(2) The average cash cost of serving customers, or Cash Cost Per User (“CCPU”) is a non-GAAP financial measure and includes all network and general and administrative costs as well as the subsidy loss unrelated to customer acquisition. Subsidy loss unrelated to customer acquisition includes upgrade handset costs offset by upgrade equipment revenues and other related direct costs. This measure is calculated as a per month average by dividing the total costs for the specified period by the average total customers during the period and further dividing by the number of months in the period. We believe that CCPU, which is a measure of the costs of serving a customer, provides relevant and useful information and is used by our management to evaluate the operating performance of our business.

(3) Cost Per Gross Add (“CPGA”) is a non-GAAP financial measure and is calculated by dividing the costs of acquiring a new customer, consisting of customer acquisition costs plus the subsidy loss related to customer acquisition for the specified period, by gross customers added during the period. Subsidy loss related to customer acquisition consists of costs directly incurred to acquire new customers – such as handset and accessory costs – offset by related revenues. We believe that CPGA, which is a measure of the cost of acquiring a customer, provides relevant and useful information and is used by our management to evaluate the operating performance of our business.

(4) OIBDA is a non-GAAP financial measure, which we define as operating income before depreciation and amortization. In a capital-intensive industry such as wireless telecommunications, we believe OIBDA, as well as the associated percentage margin calculation, to be meaningful measures of our operating performance. OIBDA should not be construed as an alternative to operating income or net income as determined in accordance with GAAP, as an alternative to cash flows from operating activities as determined in accordance with GAAP or as a measure of liquidity. We use OIBDA as an integral part of our planning and internal financial reporting processes, to evaluate the performance of our senior management and to compare our performance with that of many of our competitors. We believe that operating income is the financial measure calculated and presented in accordance with GAAP that is the most directly comparable to OIBDA.

(5) OIBDA margin is a non-GAAP financial measure, which we define as OIBDA (as described in note 4 above) divided by total revenues less equipment sales.
