The XP3 - A mobile handset with advanced features and functionality that's built to serve the most demanding users' real-world needs now and into the future. But the XP3 is far more than a simple container for communications service. Sonim mobile is setting the new standard for ruggedized phones. The XP3 headset was built for people who use their mobile phones as tools, not fashion accessories. It's engineered to be equally at home in a factory and forest, a construction site or a mountain, on a boat in the middle of the ocean or a dry, sweltering desert. The XP3 was created to suit people who value solidly constructed tools that are built to last rather than disposable devices.
