International Networks is the name given by the International Telecommunication Union (ITU) to country calling codes +882 and +883, and serves as a catch-all for telephone services not dedicated to a single country.
Satellite telephone carriers, especially those with worldwide service, are allocated within the Global Mobile Satellite System (GMSS), country code +881, with the exception of non-terrestrial Inmarsat, country code 870.
The phone number for a subscriber of such a service starts with +882/+883 followed by the carrier code.
The cost to call such a number can be high; for example in the British Telecom price list rates for various 882 and 883 numbers ranged from £0.60 to £4.50 per minute.
