Sonim Technologies, the makers of the world's most rugged phones, announces the Sonim XP3 Sentinel, the cornerstone of a new safety solution for Lone Workers. Custom-designed for vertical markets including the energy, utilities, construction, security, forestry and logistics sectors, the XP3 Sentinel will keep remote workers safe while in isolated and hazardous environments.

Peoplesafe (UK), TrackaPhone (UK), SafelinQ (global) and GEOS Alliance (US/Canada) are Sonim's launch partners for the monitoring services and servers announced today. Together with these partners, Sonim's XP3 Sentinel provides an end-to-end safety solution that also includes an emergency response call center and uses the voice and data capabilities of a mobile network operator.

The Sonim XP3 Sentinel is engineered to exceed the toughest tests: it can be dropped from 2 metres onto concrete, submerged in one metre of water for up to 30 minutes and operate in temperatures from -20 to +55 Celsius. The phone has a Gorilla glass screen and meets the military-level MIL-810F certification for resistance to humidity, salt, shock and heat. The uniquely designed keypad makes it easy to use with gloved or wet hands and its 110 decibel speakers can be heard over machinery or sirens. In addition, the ergonomic design enables mobile workers to change settings and make adjustments to the phone easily, helping them stay focused on the task at hand.

"We've worked closely with Sonim to ensure this mobile phone fulfills the needs of hard hat wearing Lone Workers in water, electricity and gas utilities, the building and construction trades and the farming, manufacturing and logistics sectors, to name a few," said Ian Johannessen, Managing Director of Peoplesafe.


The Sonim XP3 Sentinel features risk management buttons (red, amber and green) simplifying the user interface and requiring no menu selections by the user. This user interaction is powerfully customized by each of Sonim's monitoring partners through their specific configuration of the XP3 Sentinel's flexible capabilities. A typical configuration is as follows:

Emergency Red Button: 

In emergencies, the user presses the dedicated red button on the side of the phone, even if the phone keypad is locked. This causes the user's GPS location to be sent to the monitoring centre, where the position appears on a map with other relevant data. A call is automatically placed to the emergency monitoring center to summon assistance. After the call, the GPS tracking will continue until the incident is resolved and the phone is remotely reset. On a full battery, GPS tracking can continue for around 24 hours at three minute intervals. For maximum reliability, Sonim has implemented red button capabilities natively in the phone's firmware. 

Amber Alert Button: 

With the amber key, the lone worker can request enhanced monitoring and tracking if they are going into a risky situation. The monitoring service may track the worker on a map and remind the user to use the phone keypad to acknowledge their safety every ten minutes until they cancel the amber alert. 

Green Button: 

The green key may be used to indicate that the user has started or ended their working shift.

For workers in risky situations, perilous environments or violence-prone situations, the Sonim XP3 Sentinel meets the device requirements of the newly issued British Standard BS8484 device requirement for Lone Worker Devices and Monitoring Stations. Sonim's UK partners have used these capabilities to ensure the complete solution meets and exceeds the duty-of-care requirements under UK Law, toughened in 2008 with the passage of the Corporate Manslaughter Act. The XP3 Sentinel has also been designed to meet the device requirements of German Lone Worker standard DIN 0825-11.
