Satellite Phones

Where can satellite phones be used, and how reliable are they?

Satellite phones operate independently of cell towers, making them essential in areas without mobile coverage, remote wilderness, offshore waters, deserts, disaster zones, and more. Reliability depends on the satellite network: Iridium offers true global coverage, including polar regions; Inmarsat covers most of the globe except the far north and south; and Globalstar provides dependable regional coverage across much of North America.

What factors should I consider when choosing a satellite phone?

Key considerations include your location, frequency of use, and required features. For global travel or high-latitude expeditions, Iridium is often preferred. For lower-cost regional coverage, Globalstar may suffice. Battery life, portability, and ease of use also matter, OSAT’s team can help guide the decision based on your exact needs.

Are satellite phones difficult to operate or set up?

Not at all. Satellite phones are designed to be straightforward, with familiar menu navigation and dialing. Many also include emergency features like GPS tracking or SOS messaging. OSAT provides setup support and user guides to ensure you’re fully prepared before heading out.

Do I need a specific service plan or subscription to use a satellite phone?

Yes, satellite phones require a dedicated airtime plan. These range from flexible prepaid options for occasional use to monthly contracts for consistent fieldwork. OSAT offers service across all major networks and can activate your plan before your device even ships.

How long do satellite phone batteries last, and can they be recharged off-grid?

Most satellite phones provide several days of standby time and 4–8 hours of talk time per charge. For extended trips, OSAT recommends carrying a spare battery or compatible solar charger, available as part of our accessories range.
