MCI Transforms Web Portal For Business Customers

MCI Customer Center Gets New Look, Increases Usability through Comprehensive Suite of Web-based Applications

ASHBURN, Va., March 1, 2005 - MCI, Inc. (NASDAQ: MCIP) today announced it is transforming its online customer management portal to help companies around the world better manage their MCI communications solutions. The updated MCI Customer Center (MCC) features an easier-to-use Web portal, more streamlined and integrated functionality and a richer set of interactive features.

"MCI's first priority is to improve the customer experience with best-in-class service and support," said Nancy Gofus, senior vice president of Product Management. "With our updated online customer center, MCI is delivering an expanded suite of self-management tools, such as Private IP WAN Analysis and a more comprehensive view of our customers' networking and hosting environments."

With a new look and feel, MCC makes it easier for customers to stay informed regarding their networking operations and take advantage of dozens of additional features to manage their communications infrastructure more efficiently. MCI customers can now securely tap into more Web-based applications, enabling them to order new services, track and resolve trouble tickets, manage inbound voice traffic, review and pay MCI invoices online, monitor network and hosting operations and receive advice on technical or security issues.

As part of the personalized MCC homepage, customers can access the new Info Center (iCenter) where account-specific updates are posted in near real-time, including maintenance notices, key reminders and the latest information on MCC features and functions. Through "My Profile" customers can update their user profiles to change passwords and manage personal information, including email addresses, language preference and time zone. The new MCC offers companies a choice of languages, including English, Dutch, French, German and British English with additional languages coming online later this year.

"MCI's new online portal puts an instant command and control station at my fingertips," said Paula Howe, Senior Voice Analyst, Corning Incorporated. "With its wide range of features and capabilities, I can tailor it to meet our specific requirements and manage our entire network operations right from my desktop."

Customers can easily locate information around-the-clock with its intuitive navigation. For example, customers can review, analyze and pay MCI invoices online with the click of a mouse. Over the past year, MCI has experienced a 163 percent increase in customers utilizing its e-billing capabilities.

With MCI's Web-based billing, customers gain access to complete call details and associated billing reports. Customers can benefit from being able to isolate and review charges, as well as reduce the need for paper storage or disposal and the associated costs. Businesses also have the ability to retrieve stored invoices online for up to seven years.

MCC is available immediately to all MCI customers across all regions and can be accessed at customercenter.mci.com. Visitors to MCC can take a virtual tour of the center to learn more about it.
