PT Indosat Tbk, operating under the name Indosat Ooredoo Hutchison (IOH), is a telecommunications company in Indonesia owned by Ooredoo Hutchison Asia, a joint enterprise formed by Ooredoo and Hutchison Asia Telecom Group (a subsidiary of CK Hutchison Holdings) since 2022. The firm delivers wireless mobile connectivity and broadband internet services through its IM3 and Three brands, which differ in their pricing structures and payment methods. Additionally, Indosat offers international direct dialing (IDD), fixed-line telephony, and multimedia solutions.

In February 2013, Qtel, which was the principal shareholder of Indosat, rebranded itself as Ooredoo. This change led to the renaming of its subsidiaries, including Indosat, which adopted the name Indosat Ooredoo on 19 November 2015.

By the end of Q4 2018, Indosat had accumulated 58 million subscribers, a decline from 110 million in 2017, capturing a 16.5% share of the Indonesian mobile market as the country's second-largest operator.

1967

Indosat was founded as Indonesia’s inaugural foreign-invested company providing international telecommunications via satellite. Initially, it was owned by the American corporation ITT, through its subsidiary American Cable and Radio Corporation, until the year 1980.

1980

Indosat became the first international telecommunications company to be entirely acquired and fully controlled by the Indonesian Government.

1994–2003

During this period, Indosat took majority ownership in Satelindo and SLI and established PT Indosat Multimedia Mobile (IM3) to launch Indonesia’s first nationwide GPRS network. In 2003, it consolidated its operations by merging with subsidiaries Satelindo, IM3, and Bimagraha into a single mobile network operator entity.

2003–2009

Indosat obtained a 3G license and introduced 3.5G services in key cities such as Jakarta and Surabaya. In 2009, Qtel acquired a 24.19% stake previously held by public shareholders, becoming the majority owner with a total of 65% shares. During this timeframe, Indosat also secured additional frequencies for its 3G network and won the government tender for WiMAX services.

2012–2020

In 2014, Indosat commenced commercial deployment of its 4G network on the 900 MHz band, initially providing download speeds up to 42 Mbit/s in major urban areas with plans to expand coverage to rural regions. The company adopted the name Indosat Ooredoo in November 2015 following rebranding efforts. In 2016, it collaborated with Swedish streaming platform Spotify, becoming Indonesia’s first telecom operator to offer integrated Spotify music services.

2021–present

In January 2021, Indosat announced its withdrawal from satellite operations. Later that year in September, it revealed plans to merge with PT Hutchison 3 Indonesia—a joint venture between Hutchison Asia Telecom Group and Garibaldi Thohir operating the 3 network—to establish Indosat Ooredoo Hutchison (IOH). This merger was officially finalized on 4 January 2022.
