The Inmarsat IsatPhone 2 is a dependable handheld satellite phone designed to provide clear voice communication and messaging in remote locations where conventional mobile networks are unavailable.
Built for international travel, expeditions, maritime use, field operations and emergency preparedness, the IsatPhone 2 provides a straightforward way to stay in contact across much of the world. It is an ideal choice for individuals and organisations that need reliable communication without the complexity of a more advanced satellite terminal.
Reliable Communication Beyond Mobile Coverage
Operating through Viasat’s global L-band satellite network, the IsatPhone 2 delivers high-quality voice communication across up to 99.9% of the world’s landmass, excluding the most extreme polar regions. This extensive coverage makes it well suited to remote journeys, offshore operations and isolated worksites where terrestrial infrastructure cannot be relied upon.
The handset can be used to make and receive satellite calls, exchange text messages and maintain essential contact with family members, colleagues or operational teams.
Designed for Remote and Demanding Environments
The IsatPhone 2 is built for users who may encounter challenging weather, difficult terrain and long periods away from established communication networks.
Its robust handheld design makes it suitable for carrying in an expedition pack, storing aboard a vessel or including within an emergency communications kit. The handset is particularly valuable for remote workers, adventure travellers, NGOs, government teams and businesses operating across areas with limited mobile coverage.
Straightforward Satellite Communication
Despite being designed for remote environments, the IsatPhone 2 operates in a familiar and accessible way. Users can place calls and send messages using traditional phone-style controls, making it a practical option for both experienced satellite-phone users and those using one for the first time.
For the most reliable connection, the handset should be used outdoors with its antenna extended and a clear, unobstructed view towards the satellite.
A Practical Choice for Travel and Emergency Planning
Whether used as a primary communication device in the field or as a backup when terrestrial services fail, the IsatPhone 2 offers valuable reassurance in locations where staying connected cannot be taken for granted.
Its combination of extensive satellite coverage, straightforward operation and durable construction makes it a proven communication solution for remote travel, maritime activity, disaster planning and professional field operations.
Not all mobile networks allow you to send text messages to satellite phones and as a result, text messaging can be unreliable. Please check with your provider or contact us for further information.
