Sonim’s professional and powerful power tools do well on the construction site. They are resistant to crushing, puncturing, dust, scratches and impacts (including withstanding a 2-meter drop onto concrete), and with a lifetime of more than 3 years, they offer low total cost of ownership (TCO). Professional Push-to-Talk (depending on network vendor) and man-down monitoring keep work teams coordinated and secure.

Transportation and logistics

Chain suppliers, transportation services, field facilities, maintenance and cab companies have fleets and drivers in need of specialized communication solutions. Ports, airports and rail carriers around the world rely on Sonim to coordinate containers, maintenance personnel and cargo aircraft. With accessories specifically for in vehicles, control via GPS, Push-to-Talk and lone worker safety solutions, Sonim is in all markets.

Security and facility management

For private security, commercial cleaning services, facility maintenance and hospitality, Sonim phones help lower operating costs, improve response time and keep staff safe and accountable. With Push-to-Talk, proof of activity, indoor/outdoor location monitoring and lone worker protection, one Sonim device can replace many others. Heavy-duty battery capacity, plus ultra rugged reliability of 3+ years of use, ensure flawless operation and satisfied customers.


Personnel from water, electricity, gas and telecom companies work underground with cables and pipes, climb towers, descend manholes and spend time on the road. Out of range means out of order. Sonim phones withstand all weather conditions, mud, water and drips for years, locate the technician on the road or on site and make direct contact and coordinate employees with Push-to-Talk.
