Indosat offers (prepaid and postpaid) mobile phone services (Mentari, IM3 and Matrix), fixed voice services (including International Direct Dialing (IDD)), fixed wireless and fixed telephone services.[3][4] The company also provides Multimedia, Internet & Data Communication Services (MIDI).[4]

As of 2012 the company holds around 21 percent of market share. It has around 50 million cellular subscribers.[3] An Indonesian investment website stated that the company has lost a couple of percentage points in terms of market share on the mobile phone market in Indonesia in recent years.[3] listed the company as the third largest telecommunications company in Indonesia in 2013, coming behind Telkomsel and XL Axiata.[5]


Indosat has long history of ownership and change of purpose and goals from its establishment on 10 November 1967.[3][6] After being bought by Indonesian government from foreign investment company, the company began as a commercial international telecommunications service provider (IDD) in September 1969.[6] The company connected to Intelsat (International Telecommunications Satellite Organization), an earth station in Indonesia, to access Intelsat's Indian Ocean Region satellites until 1989.[6]

The company's shares were registered on the Indonesia Stock Exchange on 19 October 1994 (code: ISAT).[3] Its form of American Depositary Shares are registered at New York Stock Exchange (NYSE:IIT).[4]

Between 1999 and 2000 the company went from Indonesia’s international telecommunications provider to an integrated telecommunications network and service provider.[6] In 2001 the company signed an agreement with Telkom to eliminate its cross-shareholdings in several operating subsidiaries; among others Satelindo, Telkomsel, and Lintasarta.[6]

In 2006 Indosat became a member of Conexus Mobile Alliance to enhance its international roaming and corporate mobile services for voice, video and data roaming.[4][7] The alliance has a combined customer base of about 350 million mobile subscribers via its GSM/GPRS, W-CDMA networks and/or HSDPA networks.[7]
