The Iridium system was designed to be accessed by small handheld phones, the size of a cell phone. While "the weight of a typical cell phone in the early 1990s was 10.5 ounces" [6] (300 grams) Advertising Age wrote in mid 1999 that "when its phone debuted, weighing 1 pound (453 grams) and costing $3,000, it was viewed as both unwieldly and expensive."
Iridium Communications Inc. (formerly Iridium Satellite LLC) is a publicly traded American company headquartered in McLean, Virginia, United States. Iridium operates the Iridium satellite constellation , a system of 80 satellites: 66 are active satellites and the remaining fourteen function as in-orbit spares. [ 2 ]
A satellite telephone, satellite phone or satphone is a type of mobile phone that connects to other phones or the telephone network by radio link through satellites orbiting the Earth instead of terrestrial cell sites, as cellphones do.

Two such constellations, intended to provide satellite phone and low-speed data services, primarily to remote areas, are the Iridium and Globalstar systems. The Iridium system has 66 satellites, which orbital inclination of 86.4° and inter-satellite links provide service availability over the entire surface of Earth.
Leveraging upgraded satellite constellation, the new broadband service offering is likely to fortify Iridium's (IRDM) market presence with improved maritime and land-mobile applications.
From 2009 certain Iridium satellite phone models were shipped with both LetterWise and WordWise though not necessarily enabled by default; [28] [30] [31] as of May 2019 some of these models seem current. [33]
Telephone calls to satellite terminals are often accomplished by dialing numbers assigned to the Global Mobile Satellite System, although most Globalstar users and some Iridium users are assigned country-based numbers. Thus, calls can be made to satellite phones from normal land-line and cellular terminals.
