Truphone, a global wireless carrier, is developing a global roaming application based on RIM's BlackBerry (News - Alert) 10 platform.

Officials with Truphone said that the new application will let BlackBerry 10 users make international calls and send text messages over Wi-Fi or 4G/LTE (News - Alert) at rates up to 90 percent cheaper than mobile operator tariffs.

According to company officials, BlackBerry 10's advanced APIs, new programming tools, intuitive programming environment and developer features are enabling Truphone (News - Alert) 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 (OTT) services that take advantage of the BlackBerry 10 platform.

"RIM has got it right with the BlackBerry 10 platform. They have really streamlined the app-development process," said Adam Linford, head of labs and mobile applications, Truphone, in a statement.

Linford said that the platform's support for open-source components flattens the learning curve enabling the company to build a new application quickly and cost-effectively and have it ready to go when the first BlackBerry 10 devices debut.

Company officials pointed out that 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 BlackBerry 10 application will be the product of two things: Our leadership in being first to market on new platforms, and RIM's visionary approach in developing a platform that's developer-friendly," said Linford.

He said that the company’s new BlackBerry solution will debut at a time when Wi-Fi offloading and other OTT services begin to reach the tipping point to become the business traveler's must-have options for reliable, global and cost-effective communications.
