Perusahaan Perseroan (Persero) PT Telekomunikasi Indonesia Tbk, commonly known as Telkom Indonesia, is Indonesia’s largest integrated telecommunications service provider. Majority-owned by the Government of Indonesia, the company traces its modern corporate structure to its 1991 incorporation under Law No. 3 of 1989, although its operational roots date back to the colonial-era postal and telegraph services of the mid-19th century. Telkom Indonesia is headquartered in Jakarta and Bandung and employs a network of subsidiaries and associates to deliver a comprehensive suite of connectivity solutions across the archipelago.
The company’s core activities encompass fixed-line and mobile telephony, broadband internet, and data communications. Through its flagship mobile arm, Telkomsel, it operates one of the country’s largest cellular networks, offering 4G and 5G services to consumers and enterprises. On the fixed-line side, Telkom Indonesia provides fiber-to-the-home (FTTH), digital subscriber line (DSL), and Wi-Fi access under the IndiHome brand. Complementing these services, the company has developed a range of IT and network solutions—including cloud computing, data center hosting, cybersecurity, Internet of Things (IoT) platforms and managed network services—targeted at the enterprise sector.
Beyond its domestic footprint, Telkom Indonesia maintains strategic regional operations and partnerships across Asia-Pacific and the Middle East. It owns and operates undersea cable assets to enhance international connectivity and serves multinational corporations through offices in Singapore, Australia and other regional hubs. The company also invests in technology ventures and digital start-ups, aimed at accelerating Indonesia’s digital economy and expanding its presence in emerging digital markets.
Telkom Indonesia is governed by a board of commissioners and a board of directors appointed by the government, reflecting its status as a state-owned enterprise. Under this leadership structure, the company continues to focus on network expansion, digital transformation initiatives and sustainable growth strategies to support Indonesia’s ongoing infrastructure development and increasing demand for advanced telecommunications services.
