Global Mobile Satellite System

Short description: none

The Global Mobile Satellite System (GMSS) consists of several satellite phone providers serving private customers. It can be compared to PLMN (wireless telephony carriers) and PSTN (traditional wire-based telephony).

As of 2023, ranges of numbers have been assigned to two GMSS carriers:

* Iridium Satellite LLC
* Globalstar

In 1996, the ITU introduced country code +881 for direct international dialing of phones on GMSS providers. (Inmarsat had already been allocated country code +870.) The next digit following the country code is allocated (two at a time) to a particular GMSS carrier:[1][2]

Carrier | GMSS codes

|

spare
(formerly ICO) | +881 0
+881 1
spare
(formerly Ellipso) | +881 2
+881 3
spare | +881 4
+881 5
Iridium | +881 6
+881 7
Globalstar | +881 8
+881 9

## Satellite numbers outside the GMSS country code

Inmarsat is a satellite-based communications provider, but it is primarily a maritime service and is not generally considered part of the GMSS.

Globalstar usually allocates subscribers with a local number in the country they are based rather than using their GMSS country code.

Iridium also uses an Arizona-based access number to call Iridium phones for those unwilling or unable to call the usually expensive GMSS number directly.[3]

Thuraya has been assigned +882-16, within the +882 range for International Networks.
