Sento Corporation Selected to Provide Multi-Channel, Multilingual End User Support to mBlox

Sento’s Outsourced End User Support Service will Enable mBlox to Provide a High Level of Support While Lowering Costs and Increasing Geographic Reach

Salt Lake City, Utah – January 11, 2006 – Sento Corporation (Nasdaq: SNTO), a right- channeling solutions leader, announced today that mBlox, the world’s largest mobile transaction network, has chosen Sento to provide scalable, outsourced multilingual support service for end user inquiries. The deal will allow mBlox to continue its international growth while also reducing support costs without compromising workflow processes or the degree of professional service it offers throughout all of its operations. mBlox will continue to service its business clientele with in-house engineers.

Eliminating mobile business complexity is a cornerstone of mBlox’s business. mBlox needed a partner with technically-skilled, multilingual agents that would enable it to maintain a high standard of service for its end user support, as it continued to grow internationally.

“We needed a partner who could manage the end user support services piece of our business while we focused on continuing to grow domestically and internationally, and implementing mechanisms to improve efficiency for our clients worldwide,” said Natalie Diggins, vice president of global operations for mBlox. “We selected Sento as our end user support service partner because we trust them to handle inquiries from end users and provide them with the same high level of service they would expect to get from mBlox directly.”

Using Sento’s multilingual end user support services across multiple contact mechanisms, mBlox will be able to ensure that when users need service, they are being assisted by highly-trained, multilingual agents who are very efficient at addressing their specific needs.

“We are pleased to be helping mBlox with both its expansion and its goal of reducing workflow complexity and customer support costs,” said Patrick O’Neal, president and chief executive officer for Sento. “The integrity and expertise of our agents will ensure that each support services interaction will be handled efficiently regardless of geographic location or native language.”
