Unlimited Wireless Carrier MetroPCS Launches Service in Los Angeles
New Unlimited, Flat Rate, No Signed Contract Calling Plans Are Most Affordable in the Market
LOS ANGELES, Calif. – (September 19, 2007) – Los Angeles area residents now have a new alternative to costly traditional wireless service plans. MetroPCS Communications, Inc., the nation’s leading provider of unlimited wireless communications service, today announced the launch of its flat rate unlimited wireless service in Los Angeles. MetroPCS will provide the people of Los Angeles the freedom to enjoy more flexible wireless options with no signed contracts and truly unlimited local and long-distance service. With plans starting as low as $30 a month, MetroPCS offers the lowest unlimited wireless calling choices now available in the market. Already available in Northern California, including the San Francisco and Sacramento markets, the Los Angeles service launch means expanded wireless coverage and an added value for customers throughout California.
     MetroPCS offers a diverse selection of “talk all you want” plans and enhanced service packages so that Los Angeles residents can create a customized wireless experience that best fits their lifestyle. With MetroPCS service plans, customers pay by the month, not by the minute, and services do not require a signed contract, minimum balance or deposit. Long distance service to the 48 contiguous states is available with service plans as low as $35 a month. Customers who sign up for service will receive the first month free with their purchase of a MetroPCS phone.
     “Los Angeles has a very diverse consumer base whose lifestyles and wireless needs vary,” said Robert Wondoloski, vice president and general manager of MetroPCS Los Angeles. “As a new member of this community, MetroPCS demonstrates its commitment to the area by offering consumers in Los Angeles a new, more flexible and affordable option for unlimited wireless service.”



     Roger Linquist, MetroPCS’ Chairman of the Board and Chief Executive Officer, added: “We are excited about launching our unlimited flat rate service in Los Angeles and anticipate that Los Angeles has the potential to be MetroPCS’ most successful market launch ever. This service launch represents a significant near-term potential source of growth for MetroPCS and positions us well to continue delivering value to our shareholders. MetroPCS is one of the fastest growing US wireless carriers, driven by what we believe is a unique value proposition to our customers. We expect our service to initially cover approximately 11 million Los Angeles consumers following today’s launch. The company has produced extraordinary subscriber growth and growth in consolidated EBITDA over the past two and a half years, and the Los Angeles service launch demonstrates that our strong momentum is continuing. Los Angeles is a unique and significant opportunity for MetroPCS as it has an extremely high population density in target coverage areas and has ideal demographic requirements for our service offerings.”
     With more than 3.5 million subscribers nationwide, continued consumer demand for MetroPCS’ unlimited, no signed contract, flat rate wireless service has been the driving factor behind the company’s expansion in California (and across the country). In addition to the launch of its flat rate service in the Greater Los Angeles market, MetroPCS expresses its continued commitment to the communities it serves, with plans to open 20 new company owned retail stores throughout the Greater Los Angeles area in the next two years, resulting in over 300 direct new jobs plus an additional 1,500 estimated jobs, involving authorized dealers.
     While options and services depend on the selected plan, subscribers can further enhance their service with “unlimited” advanced feature packages that include voicemail, caller ID, call waiting, three-way calling, text and picture messaging, push e-mail, mobile Internet browsing, mobile instant messaging, and the recently announced unlimited Metro411, a voice-activated, premium directory assistance service. Consumers can visit any of MetroPCS’ current Los Angeles area 400 authorized dealer locations and six company owned retail locations or visit MetroPCS’ Web site at www.metropcs.com to sign up for service plans, and choose from a lineup of today’s trendiest wireless phones.
