Satellite phones for emergency communication

updated 25th March 2014

Satellite communication phones have long been standard kit for news reporters and some businesses that operate in globally remote areas.
Now, with Inmarsat's introduction of the affordable IsatPhone Pro, hand-held satellite phones should fast become standard emergency preparedness equipment for all. With voice calls costing as low as £0.65 per minute to any landline in the world and a handset price of around £550, the IsatPhone Pro satellite phone is essential for emergencies but is also proving useful for remote workers and expedition leaders. The IsatPhone Pro is a robust handset that offers voice calls, sms, short message email in addition to GPS look-up-and-send.

Coming soon: Isat Phone 2


Who needs a satellite phone?

  • Any organization that requires a mobile emergency communication system as a component of their contingency plans
  • Businesses of all sizes can include a satellite phone in their business continuity kit
  • Families should consider a satellite phone in the home as part of their emergency preparedness kit
  • Schools and other educational institutions that lead field trips and expeditions into remote areas
  • Adventurers and sports enthusiasts that venture off the beaten path
  • Mariners and boat owners for onboard telephony and as part of your ditch bag

Why the need for satellite phones?

  • Satellite phones are independent of the terrestrial landline telephone system which has been known to fail during major incidents
  • Satellite phones are also independent of the mobile phone system which is often locally overwhelmed during times of crisis
  • A satellite phone will often be your only method of voice communications with the outside world during a large scale emergency
  • Portable satellite phones can be used in the field, or at sea, where there is often no cellular network phone coverage available
  • Use the satellite phone to call for rescue in an emergency anywhere in the world or use it simply to report to base

Why the IsatPhone Pro?

  • Handset specifically designed for use in the field: in rain storms, dust storms, searing heat to sub-zero cold, tropical humidity or freezing fog
  • Long battery life: lasts up to 8 hours talk-time and up to 100 hours on standby
  • Global coverage for: voice telephone, voicemail, text message, short email message, can also send your GPS location co-ordinates by text or email
  • Easy to use handset: Intuitive GSM style operation
  • Reliable network connection: operates over global geo-stationary satellites that will be operational for decades

How does the IsatPhone Pro work?

Your IsatPhone makes and receives calls by communicating with Inmarsat satellites in orbit above the equator. It connects to one of the new-generation Inmarsat-4 series of satellites, flying in geosynchronous orbit 37,786 km (22,240 statute miles) above the Earth. The satellite phone requires a clear line of sight between the phone’s antenna and the satellite to make and receive calls.

Practically, this means you will need to be outdoors with a clear view of the sky to use the phone. When you have a good signal, you may use your satellite phone much like a mobile phone; directly dialling a landline or mobile telephone number anywhere in the world.

Where does the Isat Phone Pro work?

Currently, there are three operating satellites in the I-4 constellation which the IsatPhone Pro uses. These cover most of the globe. The coloured areas in the coverage map below show the 'footprint' of each of these three Inmarsat-4 satellites. If you are outdoors, with a clear view of the sky, in one of these areas of the globe - including the oceans - your IsatPhone Pro should receive a strong signal - and consequently, you should be able to make and receive calls. The best reception can be found in the centre of each of the spot beams which are highlighted below in light blue, green and dark blue. The areas to the edge of each spot beam will require the antenna of the phone to be pointed in the direction of the centre of that beam to obtain the best possible reception. As an example, to establish a strong signal in the UK, you will need a clear view of the sky towards the South-East at an angle of approximately 20 degrees elevation from the horizontal.


This map depicts Inmarsat’s expectations of coverage, but does not represent a guarantee of service. The availability of service at the edge of coverage areas may require more directional pointing of the antenna to the satellite. IsatPhone Pro coverage July 2010
