How to Use

The following explains how to use the KDDI INMARSAT service from an INMARSAT B equipment.

  1. Turn on the equipment and face the antenna towards one of the satellites.
  2. Dial the KDDI Land Earth Station ID Number "003."
  3. Dial the code that represents the direct-dial code "00."
  4. Next, dial the country code followed by phone number or telex number. To call another INMARSAT equipment, dial the ocean region code for where it is located, and its ID number.
  5. Lastly, dial #.

  • From June 3, 2013, as with medical assistance communications by dialing 38#, distress calls, emergency calls and safety communications that originate from an INMARSAT B, M or Fleet terminal to the Yamaguchi LES are directly connected to the Japan Coast Guard, not via the KDDI operator. The method of making calls from ships remains the same.
