Dial ‘870’ For All Inmarsat Terminals

From 1 January, 2009, phoning Inmarsat mobiles will be easier than ever.

All Inmarsat services have now been brought into line with our most advanced voice and high-speed data services, such as BGAN and FleetBroadband.

Just dial the Inmarsat country code +870, followed by the Inmarsat Mobile Number, to reach any Inmarsat customer anywhere in the world.

You can now use the +870 country code for the following Inmarsat services:

  • Fleet 33
  • Fleet 55
  • Fleet 77
  • Inmarsat B
  • Inmarsat M
  • Mini M
  • Inmarsat GAN
  • IsatPhone
  • FleetPhone


Withdrawal of ocean region codes:

From midnight, 24:00 hours GMT, on 31 December, 2008, the four original Inmarsat ocean region codes of +871, +872, +873 and +874 will be discontinued.

In the past, you needed to know in which Inmarsat ocean region our customer was roaming - for example, the Pacific Ocean Region (+872) or Indian Ocean Region (+873).

For the above services simply dial +870 and our global satellite network will locate the Inmarsat terminal. It’s that easy. We recommend you begin dialling the +870 country code with your next call.

If you experience any problems, contact the AST Customer Support Helpline on +44(0)1493 441 485 or email
