The Iridium Extreme® Satellite Phone is a rugged handheld communications device designed for dependable use in remote locations where conventional mobile coverage is unavailable. Built for demanding environments, it is well suited to expeditions, maritime operations, emergency response, remote working, overlanding and adventure travel.
Operating through the global Iridium satellite network, the Iridium Extreme provides reliable connectivity across land, sea and air, including polar regions. Its durable construction makes it a practical choice for professionals and travellers who need a robust satellite phone capable of performing in challenging weather and field conditions.
Compact enough to carry as part of an emergency communications kit, the Iridium Extreme helps users remain connected with colleagues, support teams, family members and emergency services when working or travelling beyond the reach of terrestrial networks.
An active Iridium SIM card and compatible airtime plan are required to use satellite communication services.
When used in conjunction with GTCTrack, GTC's online advanced mapping portal, the Iridium Extreme offers a variety of advanced tracking functions such as a breadcrumb trail of historic movements, live view (position of last message transmitted) and exact location of SOS and emergency requests. These tracking functions are available with an additional subscription.
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.
