Telkom has major businesses in fixed line telephony, internet and data communications. It is operated as the parent company of the Telkom Group, which is engaged in a broad range of businesses that consist of telecommunication, multimedia, property and finance services.

Telkom is one of the world's oldest telecommunication companies. The company can be traced to an establishment of the first electromagnetic telegraph service in Indonesia on 23 October 1856, by the Dutch Colonial Government to connecting Batavia (Jakarta) and Buitenzorg (Bogor). 

In 1884, the Dutch Colonial Government founded a private company to provide postal and domestic telegraph services and, later on, international telegraph services.

After privatisation in 1995, Telkom Indonesia's total consumer base grew by 7.8% from 2010 to 129.8 million customers at the end of December 2011, making the company the nation's largest telecommunication service provider by subscribers.

According to Statista, Telkom Indonesia took the top spot of the most valuable brands in Indonesia, with a brand value of approximately 4.8 billion U.S. dollars.
