T-Mobile USA, Inc. has entered into a long term partnership with Centennial Communications to expand network coverage through a roaming agreement. Centennial will provide an enhanced GSM customer experience in the US thanks to the deal; customers will be able to roam on T-Mobile USA's nationwide GSM / GPRS network. T-Mobile customers benefit from expanded network coverage, which will include the areas of Michigan, as well as Louisiana and Mississippi.

"We're excited to provide an enhanced GSM customer experience in our U.S. markets," said Michael J. Small, Centennial's chief executive officer. "Historically, we've had only a limited roaming relationship with T-Mobile USA, and we look forward to a valuable long-term partnership with this national wireless carrier. The impact of this roaming agreement was considered when we provided our financial outlook for the 2006 fiscal year."
