De-Fi Mobile has chosen BroadSoft’s BroadWorks VoIP application platform to enable the delivery of media-rich, advanced IP features and global voice service to mobile users, regardless of their wireless carrier and with predictable, affordable pricing.

De-Fi Mobile’s new Straight Talk service disrupts the existing mobile services market by bridging the gaps between carrier networks, handset manufacturers and mobile application providers that has left subscribers with hit-or-miss call quality and often exorbitant pricing for non-local calling. Straight Talk, unveiled at Mobile World Congress, will allow users to enjoy advanced BroadWorks calling features on dual-mode handsets, and the ability to dial to and from anywhere in the world without worrying about high-cost roaming tariffs and long distance charges.

De-Fi Mobile has created its own IP Network for which BroadWorks will provide a consistent call experience across the IP domain and Circuit Switch domain, allowing WiFi-enabled mobile phones to access the SIP-based network. Through peering and interconnect agreements with over 220 carriers, cable and DSL providers globally, the De-Fi Mobile network combines carrier-grade architecture and next-generation mobile technology to deliver a seamless, feature-rich user experience.

BroadWorks provides a range of services including call routing and call continuity, providing the pre-IMS architecture required to deliver high bandwidth mobile applications direct to mobile handsets provisioned with the De-Fi SIP client. De-Fi Mobile subscribers will also have access to BroadWorks features such as simultaneous ring and alternate numbers. De-Fi Mobile subscribers will benefit from a carrier-grade quality of service at affordable, predictable costs.

Consumers can sign up for the Straight Talk service on De-Fi’s web portal at http://www.defimobile.com/, and begin using the service within minutes. Subscribers can choose phone numbers in 28 countries. Straight Talk is currently available to users of Nokia E and N series phones. Additional handsets will be supported soon.
