DAYTON, Ohio--(BUSINESS WIRE)--Sept. 30, 2002--NII Holdings, Inc. (formerly Nextel International), one of the world's leading providers of fully integrated digital wireless communication, has selected Teradata, a division of NCR Corporation (NYSE:NCR), to provide advanced data warehousing technology and business solutions for Nextel de Mexico, NII Holdings, Inc.'s largest operator. Nextel de Mexico is the first Mexican telecommunications company to implement a Teradata solution.

With a focus on improving customer retention, Nextel de Mexico needed a faster, more efficient way to calculate monthly churn and detect potential problems. By gaining a single, enterprise-wide view of its customers and initiating the use of predictive modeling and multi dimensional reports with its new Teradata solution, Nextel de Mexico will be identifying those customers most likely to churn, and will be taking appropriate action. This timely access to integrated information enables the company to take preventive measures and increase customer retention.

"Teradata's approach of focusing on solving the business challenge rather than solely addressing technology issues was a key factor in our decision," said John McMahon, vice president of business operations, NII Holdings, Inc.

"Customer churn continues to be a big issue for the industry. And churn reduction is perhaps even more important for business-to-business providers such as Nextel," said Jack Knapp, vice president of communications industry marketing at Teradata. "When you lose one business customer, it has a much greater impact on the bottom line than losing a single consumer account. Teradata's warehousing solution provides the foundation to support Nextel's rapidly expanding growth."
