Key Positive Messages

Verizon’s acquisition of MCI creates a strong, new competitor, with the products, network reach, and finances needed to succeed in a communications marketplace being transformed by rapid technological change.


    Verizon and MCI complement each other’s strength’s, creating a global broadband network that combines Verizon’s core strengths in wireless and its local and regional networks with MCI’s strong business customer base, portfolio of advanced data and IP services and extensive network assets.


    Verizon plans to invest some $2 billion in MCI’s Internet backbone, network and other systems. That includes upgrading MCI’s backbone in order to meet new competitive pressures including the combination of SBC and AT&T,


    The combined Verizon/MCI will better service governmental and business customers of all sizes, including MCI’s critical national-security customers, by creating a stronger IP platform to which Verizon can add innovative value-added services, such as better storage and security.


The MCI transaction is part of a long-term strategy to transform our network to one that will deliver new choices to consumers, meeting their growing expectations for innovative broadband and wireless services. Verizon’s investments will boost economic growth and enhance national security.


    Verizon has already begun construction of new fiber networks to homes and businesses in half of the states in which it provides local service. With its new broadband network, Verizon will become a true competitor to cable, providing video services along with blazing fast-internet connections and a robust package of voice, video and data services. Consumers will have a new choice.


    Verizon is racing ahead to compete with new Internet and wireless services that bring the innovative solutions consumers and businesses crave. For example, the creation of Iobi, which combines the Internet and telephony, and VoiceWing, which offers flat-rate VOIP service, combines the internet with the traditional portfolio of Verizon voice offerings. At the same time, Verizon Wireless, through EVDO, has pioneered the deployment of robust and mobile broadband access.


    The construction and extension of Verizon’s multi-media networks will boost economic growth and create new jobs. Broadband infrastructure is a critical part of maintaining U.S. competitiveness and U.S. leadership of the internet. Only Verizon has the strength to integrate MCI’s assets and expertise into a growing network that will have beneficial multiplier impacts on regional and state economies and across the nation.

    Verizon’s stewardship of networks serving key governmental customers, including networks used by homeland and national security agencies, will ensure that these mission-critical networks remain strong and innovative.


The sooner governments grant unconditional approval, the sooner the combined Verizon-MCI can get to work.
