The Sonim solution includes: ultra-rugged mobile phones, a suite of industrial-grade accessories, and data/ workflow applications; collectively designed to increase worker productivity, communication and safety on the job site. Sonim's Portfolio Strategy is transitioning, from producing (solely) Ultra-Rugged devices, to producing Rugged and Consumer grade smartphone devices. Sonim Technologies: Portfolio Strategy Ultra-Rugged Devices are designed for those working in mission- and business-critical environments. Engineered to withstand the most perilous conditions, ultra-rugged devices feature support for industrial-grade accessories, applications and services, making them perfect for first responders and those working in heavy industry. Rugged Devices are designed to meet the needs of the everyday worker. While still designed for durability, rugged devices feature a sleeker form factor that is most popular with those who work in the trades, transportation and security, to name a few. Consumer Durable Devices are designed for every one . Building upon Sonim’s experience and leadership in the ruggedization and durability of mobile devices, consumer durable devices bring durability to everyone at a competitive price point. Sonimís Rugged Performance Standards: Prior to Sonim, the ultra-rugged mobile device market did not have a defined set of standards for enduring, extreme, environmental conditions. Sonim devices are designed and built to meet the most demanding needs of the industry. The company considers the 12 point benchmark of endurance and durability to be a major advantage. For these reasons, the company is confident that their portfolio of Rugged and Endurance devices will attract both the Athletic and Blue-Collar Markets. Sonim Carrier Providers:
