Perusahaan Perseroan (Persero) PT Telekomunikasi Indonesia Tbk
Telkom Indonesia sells phone, internet, and data services to consumers and businesses across Indonesia.
Telkom Indonesia is the giant phone and internet company of Indonesia. If you live in the country, there is a good chance your home internet, your mobile connection, or the data running through your office comes from Telkom. It offers mobile service through its Telkomsel brand, home broadband through IndiHome, and network and data-center services for big companies and other telecom operators.
The business runs on a simple idea: people and companies need to talk and stay connected, and they pay a monthly bill for it. Telkom owns the pipes and the licenses, so it collects money from ordinary customers buying phone credit and home internet, and from businesses renting capacity, cloud space, and network services. It has been hard to beat at home because its network reaches deep into the country, including places where rivals have been slow to build. The most important recent move was combining Telkomsel and IndiHome into one unit. That put mobile and home broadband under the same roof, so the company can sell a bundle instead of fighting itself. It now serves a huge base of mobile customers and a large number of home broadband subscribers, and it keeps investing heavily in fiber and data centers to carry all that traffic.
This is a big, steady utility-like business, but it is not a rocket ship. Revenue was roughly 150 trillion rupiah in 2024, and the company returns a lot of cash to shareholders as dividends. The risks are real: competition from other mobile operators, price wars, heavy spending on network upgrades, and the fact that growth in a mature market is slow. Still, Telkom is the closest thing Indonesia has to a national digital backbone, and that position is what makes the cash keep flowing.
