Ericsson will integrate, host, manage, maintain and support the systems for the two services, and provide service offering development, market segmentation and positioning support for SunCom's prepaid and ringback tones market introduction activities.

Larry Britt, Vice President, Marketing, SunCom, says: "We continue to focus on delivering our customers a broad and complete portfolio of service plans, features, downloadables and much more. There's great demand for the flexibility, convenience and ease-of-use of prepaid service plans.

"Customers enjoy personalizing the wireless experience with ringback tones and other popular SunCom features. Once we decided to move forward and develop our prepaid services, we moved quickly providing pay-as-you-go services to the market in about 90 days. Ericsson's track record in this area helped us expedite delivery of a customized program that meets the expectations of SunCom Wireless and our customers."

Angel Ruiz, President of Ericsson in the US, says: "We are pleased SunCom Wireless has chosen Ericsson to host two more services for them; it proves that hosting is a good business model for operators when launching new services. Ericsson and SunCom have worked together in the hosting of Napster Mobile, and we look forward to further extending our strong partnership into the areas of systems integration and managed services."

There's a great potential in net subscriber additions and many potential customers need a fast track to purchase minutes and package plans without a lengthy credit check. By teaming with Ericsson, a market leader in both charging systems and managed services, SunCom is now able to deliver a desirable prepaid service to its customers, which will generate a revenue source that will only grow.

The ringback tones solution, based on Ericsson's Personalized Greeting Service, will enable SunCom Wireless customers to use songs or other sounds to replace the standard tone callers hear as they wait for their call to be answered. Ericsson takes responsibility for content aggregation, ingestion and publishing of the ringback tones service delivering a true end-to-end solution to SunCom.
