Truphone announces it's developing a global roaming application based on RIM's BlackBerry 10 platform. The new application will let BlackBerry 10 users make international calls and send text messages over Wi-Fi or 4G/LTE at rates up to 90 percent cheaper than mobile operator tariffs.

BlackBerry 10's advanced APIs, new programming tools, intuitive programming environment and developer features are enabling Truphone to slash development time and create market-differentiating features. As a result, the new Truphone app will provide a superior user experience, including reliable, high-quality Wi-Fi and 4G/LTE calling and other over-the-top services that take advantage of the BlackBerry 10 platform.

The BlackBerry 10 app also will enable Truphone to accelerate its efforts to offer converged voice and data services to BlackBerry users over Wi-Fi and 4G/LTE networks. Truphone's industry firsts include the first commercial release of a Wi-Fi calling app on Nokia N and E series smartphones in 2006. Truphone released its current BlackBerry app in 2008 to provide dial-around and callback capabilities and low-cost SMS, minimizing the cost of international communications.
