Indosat Ooredoo Hutchison (IOH), originally established as Indosat in 1967, is a telecommunications provider in Indonesia. Its inception marked the first foreign investment company in Indonesia to provide international telecommunication services using an international satellite, initially owned by American conglomerate ITT. The company underwent a significant transition in 1980 when it became the first international company to be fully acquired and owned by the Indonesian Government. Over the years, the company has seen various changes in ownership and branding. In 2003, Indosat merged with its three subsidiaries, establishing itself as a mobile network operator. The company was rebranded as Indosat Ooredoo in November 2015 following a renaming exercise by its then majority stakeholder, Qtel, which rebranded itself as Ooredoo in 2013. As of 2022, IOH is owned by Ooredoo Hutchison Asia, a joint venture between Ooredoo and Hutchison Asia Telecom Group, part of CK Hutchison Holdings. The merger with Hutchison Asia Telecom Group occurred in January 2022, forming the current entity, Indosat Ooredoo Hutchison.
