PT Indosat Tbk, (doing business as Indosat Ooredoo since 2015 due to Ooredoo's majority stake), is a telecommunications provider in Indonesia.[3] The company offers wireless services for mobile phones, and to a lesser extent, broadband internet lines for homes. Indosat operates their wireless services under a few sub-brands, among them are IM3, Mentari, and Matrix. These brands differ by their payment model (pre-paid vs. post-paid) as well as pricing. Indosat also provides other services such as IDD, fixed telecommunications, and multimedia.[4]

In February 2013, Qtel, a majority stakeholder in Indosat, rebranded itself as Ooredoo. This was followed by a renaming of all their subsidiaries across multiple countries.[5] As such, Indosat was renamed Indosat Ooredoo on November 19, 2015.[6]

As of Q3 2017, Indosat has 97 million subscribers.[7] This is a sharp increase from 2013, where the number was 58.5 million.[8] Data from 2016 shows that Indosat has 22.2% of the market share, making them the second largest mobile network operator in the country.[9]



Indosat was established as the first foreign investment company in Indonesia that provides international telecommunication services using an international satellite.


Indosat expanded into becoming the first international company that was acquired and 100% owned by the Indonesian Government.


Indosat acquired Satelindo and SLI through share majority. They also established PT Indosat Multimedia Mobile (IM3) to provide and operate a nationwide GPRS network, a first for the country. In 2003, Indosat merged with its 3 subsidiaries—Satelindo, IM3, and Bimagraha—and established itself as a mobile network operator.


Indosat was granted a 3G network license and introduced a 3.5G service in Jakarta and Surabaya. In 2009, Qtel bought 24.19% of series B shares from the public and became Indosat's majority shareholder with a 65% ownership. They were granted the use of additional 3G frequencies later that same year. Indosat also won the WiMAX bid from the government during this period.


In 2014, Indosat launched and commercialized a 4G service at 900 MHz, with a download speed of up to 42 Mbit/s. The service was first rolled out in the major cities, with planned expansions to rural areas. On November 2015, Indosat rebranded itself as Indosat Ooredoo.
