PT Telkom Indonesia (Persero) Tbk

PT TelkomIndonesia is the primary telecommunications operator in the country, providing a broad portfolio that includes fixed‑line voice services, mobile communications, broadband internet, and data centre solutions. It also offers information and communication technology (ICT) services such as cloud computing, managed services, and digital solutions for enterprises and government agencies. The company serves customers across the Indonesian archipelago, ranging from individual consumers to large corporate and public‑sector clients. Its product mix is designed to support both traditional voice traffic and modern IP‑based data traffic.

As the largest telecommunications provider in Indonesia, Telkom operates an extensive network infrastructure that spans fiber‑optic cable, microwave links, and satellite connections reaching remote islands. The firm serves a large subscriber base nationwide, giving it a dominant share of the fixed‑line and broadband markets. Its scale enables it to undertake national projects, such as the development of the national data centre and the rollout of 4G/5G services across provinces. This nationwide reach positions Telkom as a critical component of Indonesia’s digital infrastructure.

Telkom’s distinguishing attributes include its status as a state‑owned enterprise, which gives it a mandated role in supporting national connectivity and government digital initiatives. The company’s involvement in the 2024 ransomware incident—where it collaborated with domestic and international partners to decrypt data held by the Lockbit 3.0 group—illustrates its technical capability in cybersecurity response and its responsibility for safeguarding critical information assets. Additionally, Telkom leverages its extensive ICT portfolio to offer cloud and managed services that help public‑sector agencies modernise their IT environments. These competencies reinforce its positioning as both a carrier and a strategic technology partner for the Indonesian state.

Structurally, PT Telkom Indonesia is owned by the Government of Indonesia and operates as a public limited company (Persero) under the supervision of the Ministry of State‑Owned Enterprises. Its ownership model means that strategic decisions are aligned with national policy objectives, including universal service obligations and the promotion of broadband access in underserved regions. The firm’s subsidiaries and affiliates cover areas such as tower infrastructure, digital advertising, and financial services, allowing it to diversify while maintaining its core telecommunications focus. This ownership and subsidiary structure underpins its ability to mobilise resources for large‑scale national projects.
