Cutting edge technology from HMD (Human Mobile Devices) aims to bridge the gap between cellular and satellite networks, and in January announced the Australian launch of OffGrid, a device that is its entry into Non-Terrestrial Network (NTN) Communications.

HMD OffGrid uses ultra-reliable L Band satellite radio spectrum, enabling any Android or IOS user to connect directly to satellites, even in the world’s most challenging environments. The device delivers satellite connectivity and features 24/7 emergency response, three-day battery life and MIL-STD-810H military grade-durability.

The device weighs a mere 60g and easily fits in the palm of your hand, making it ideal for adventurers, outdoor enthusiasts, and anyone prioritising connectivity, security and peace of mind. 

HMD OffGrid allows people to stay in touch whilst ‘off grid’ via the OffGrid app, enabling two-way messaging and live location tracking for up to five recipients. It also has a ‘check in’ feature, allowing you to send a pre-configured message to friends and family in just the click of a dedicated button.

The device also comes with Overwatch x Rescue, a SOS service that includes 24/7 multi-lingual emergency response coordination and fully funded assistance for customers that live, work, and play off the grid.

This is a device that requires a subscription plan though, which is tailored to various levels of adventure. Off-gridders can stay connected no matter their budget, with all flexible plans providing critical support with access to a premium search and rescue service.
